The U.S. Environmental Protection Agency (EPA) has updated climate change data on its website for the first time in 5 years. The data is presented on the Climate Change Indicators website, the website allows the public to explore data generated primarily by federal agencies on climate change and its impact on people throughout the U.S. The first Climate Change Indicators report was published by the EPA in 2010, and the data was regularly updated on its website until the Trump administration in 2016. During his presidency, Donald Trump was openly sceptical of human-caused climate change, at times calling it a “hoax”.
The recent data presented in the Climate Change Indicators report illustrates the alarming reality of the impact of climate change across the U.S. Surface temperatures across the U.S. are rising, and that increase is accelerating. This temperature increase is the most pronounced in Alaska, which saw an average temperature rise of more than 2°C in parts, since 1925. Rising temperatures are also worsening wildfires, according to the new data. Wildfire season is starting earlier, lasting longer, and the amount of land burned each year by wildfires is increasing. Heatwaves have also become more common due to increasing surface temperatures, with occurrences tripling in U.S. cities since the 1960s. Drought is growing in the Southwest, which in turn threatens the availability of drinking water.
Coastal flooding is five times more common in cities across the U.S. today compared to in the 1950s. A combination of melting of polar ice and rising water temperatures are the cause of the flooding, with sea level rising being particularly prominent along the East Coast and Gulf Coast. The new data also shows that incidents of lyme disease have doubled since 1991, as a warming climate across the U.S. is leading to deer ticks being able to survive in an increasing number of areas.
The global cryptocurrency revolution has reached an all-time high with people actively involved in cryptocurrency investing. The idea of a decentralized currency without privacy concerns has been the key factor behind the growing popularity of these digital currencies. This has been acknowledged by institutions like Deutsche Bank, which anticipates that by 2030 digital currencies will have over 200 million users and could eventually replace cash one day. Another major factor that propels the success of already popular cryptocurrency is its portrayal as a ‘greener’ alternative to traditional cash and its potential to evolve into a global currency. However, Elon Musk stirred global controversy when he questioned the environmental impact of cryptocurrencies, and subsequently declined to accept Bitcoin for Tesla payments.
The exchange rate of Bitcoin has fallen drastically, due to subsiding hype and excitement, the prevalence of common sense, and the global audience shifting their attention to how much energy is actually consumed by these cryptocurrencies. The potential conflict between these ‘future global currencies’ and the efforts being made towards ‘a sustainable future’ is intriguing. This article attempts to understand this potential conflict through a detailed analysis of the energy consumed by cryptos, its incompatibility with the idea of a sustainable future, and the challenges it poses to a greener tomorrow.
Cryptocurrency Mining and Energy Consumption
Cryptocurrencies, unlike the traditional banking system of maintaining account balances in a central database, make use of a distributed network of ‘miners’. These are a network of specialized computers that keep a record of new and constantly added blocks. A computational race exists between these miners to earn incentives, and as such blocks can only be recorded by solving cryptographic puzzles. Incentives or bonuses are only given to the recording miner. While on the one hand this assures a fail-proof system, on the other, it requires huge computational power. This mining process tends to lose efficiency due to the rising prices of the cryptocurrencies, because the mathematical puzzles to create blocks become more complex and require more computation power to keep the number of transactions constant. This means more computing power and energy is being consumed per block to process the same number of transactions in the face of the increasing complexity of the puzzles.
As per recent research by the University of Cambridge which aims to create a Bitcoin electricity consumption index, it has been estimated that the miners of Bitcoin alone are going to consume 130 Terawatt-hours of energy (TWh). This energy is close to 0.5% of global electricity consumption. Just like any other conventional source of energy, electricity has its fair share of carbon emission issues. Using the standard global scale, such an amount of electricity usage would put the Bitcoin economy on par – in terms of carbon dioxide emissions – with a small developing nation. It is also interesting to note that 65% of Bitcoin mining takes place in China, where the major source of electricity generation is coal burning. Many other countries around the world are primarily dependent on coal and fossil fuels for electricity generation. This is even more concerning as coal burning is a significant contributor to climate change, owing to the high carbon emission rates associated with it. An alarming report by CNBC suggests that Bitcoin alone produces 35.95 million tons of carbon dioxide emissions every year.
The Paris Agreement and Sustainable Development Goals
Under Article 2(c) of the UN Paris Agreement (a legally binding international treaty on climate change adopted by 196 Parties at COP 21 in Paris on 12 December 2015) every signatory is obligated to make attempts to hold global temperatures within 2°C above pre-industrial levels. This agreement also reflects the understanding that the future of international finance must include a to switch to low greenhouse gas emissions. Thus, the signatories that allow for such crypto-mining to continue are directly violating the agreement. Furthermore, the central idea of the agreement was to enable modern technology to be utilized in a way that mitigates greenhouse gas emissions to the highest standard possible. The highly polluting use of technology, such as that discussed above, would be in stark contravention of the spirit of the agreement.
The Sustainable Development Goals (SDGs) are a global agenda which was adopted by countries in 2015 with a vision to end poverty, protect the planet, and ensure that all people enjoy peace and prosperity. The 17 SDGs and 169 targets are part of what is known as ‘the 2030 Agenda’ which recognizes that “eradicating poverty in all its forms and dimensions, including extreme poverty, is the greatest global challenge and an indispensable requirement for sustainable development”. Usage of cryptocurrencies directly contradicts these goals which were formulated to ensure a sustainable and better future for humanity. They directly go against SDGs 7, 9, 11, and 12 which deal with ensuring affordable and clean energy, industry, innovation and infrastructure, creating sustainable cities, and responsible consumption and production respectively.
The Solution: Revamping the Crypto-Model
The analysis of the various reports and the due examination of the crypto energy consumption pattern highlights that the seemingly ‘green’ currency actually has a huge carbon footprint. The present generation of the human race, in its efforts to tackle global climate change, has been constantly trying to transition towards more energy-efficient technology. Millions of dollars are being poured into research and development to come up with sustainable and green technology. On the face of this, the growing popularity of cryptocurrencies can be seen as a major setback because, in their present state, they endanger the future of human civilization.
With global temperatures increasing, we have seen a fresh rise in global warming-related issues. Whether it be as a result of untimely flooding or pre-season blooming, the very existence of human life is being threatened. People are forced to leave their homelands because of climate stressors. It is ironic that the currency which promised to, in a way, mitigate the challenges of the global climate crisis has itself become one of its major causes. The energy consumption of these cryptocurrencies and the hope of a sustainable future are antagonist pairs; neither can live while the other survives. The key lies not in the complete abandonment of cryptos but a gradual transition to more energy-efficient ways of mining them.
Whether you’re in favor of cryptocurrencies or against them, there is little doubt that these blockchain-based currencies use enormous amounts of energy. Much of this energy usage comes from burning coal and other fossil fuels, although cryptocurrency advocates have argued that renewable sources are also a major component. While the exact figures are disputed, even the best-case scenarios indicate that mining is a major factor in carbon dioxide emissions. Thus, the question that naturally follows is: do we abandon the cryptocurrency framework? The answer to this question is tricky. While there is no denying that cryptocurrencies in their present state of operation are a great threat to the idea of sustainability, there have been recent developments of alternate cryptos which are more promising and less energy-consuming. For instance, Ripple (XRP) consume only 0.0079 KWh per transaction – this is highly power-efficient when compared to Bitcoins. Further, new forms of energy-efficient crypto mining are being introduced.
Cryptocurrencies, in their current form, are not only highly inefficient, but their continued usage can pose considerable danger to the future of humans. There is more than one solution to the problem: from devising a better mining strategy, to transitioning towards greener energy for mining. The entire concept is so nascent that hardly any academic debate or scientific report available could suggest concrete plans. However, looking at the growing popularity of cryptos, it is pertinent to note that there indeed exists a problem and the need of the hour lies not in ignoring it, but rather starting a meaningful discussion to come up with better strategies to effectively tackle it.

The Canadian Association of Refugee Lawyers (CARL) is preparing a report parallel to the UN High Commissioner for Refugees Canada’s invitation for the federal government to examine its own laws with relation to climate change and migration. In their view, Canada is not paying due attention to the impending crisis.
In a podcast, which discussed the report, different solutions were explored. For example, it was argued that climate refugees are in fact no different from those who can get refugee status by escaping from persecution based on race, religion and political opinion; and that on this ground, no disparate treatment is necessary. Or another point was raised, that climate migrants could fall under the existing category of those applying for residency in a foreign country, after a natural disaster made their previous residence uninhabitable. It was also stated in the report that Canada’s sponsorship program for Syrian refugees could be utilized and adapted to leave room for those fleeing climate change.
The authors of the report hope that the proposed reinterpretation of exisiting regulations will be met with support from the Canadian public.
Amid ongoing global debate around the definition, classification, and treatment of ‘climate migrants’, little attention is paid to what the people affected want.1 There have been multiple reports with varying estimates of the number of people expected to be displaced due to climate change by 2050. 2,3 The common link featured in these reports, however, is that the majority of climate displacement is and will be internal. People around the world will be forced to relocate within their own countries to escape the slow onset impacts of climate change. Even in the face of uninhabitable conditions, people are generally unwilling to leave their homes and relocate to foreign lands. So, in addition to arguing over cross-border arrangements, countries ought to come up with inward-looking strategies to deal with climate-induced displacement.
One needs to look no further than the island states in the Pacific as examples. These small island nations are more vulnerable to the acute effects of climate change than any other region in the world. 4 Sea-level rise, amongst other climatic changes, is threatening the existence of these geographically isolated and small landmasses. Kiribati, which rises no more than two meters above sea-level at its highest point, is one such island state. A 2016 United Nations report has shown that half of the households have already been affected by sea-level rise on one of Kiribati’s constituent islands.5 In neighboring Tuvalu, a UNU-EHS study found that 97% of surveyed households had been impacted by natural hazards between the period 2005 and 2015, yet only 53% of the people affected believed that they would be able to afford migration in the future.6
Despite the above, people of these nations have been unwilling to leave their homes, families, and lives. New Zealand’s Pacific Access Ballot, an annual lottery which selects people from five Pacific countries for New Zealand residency each year, has repeatedly had quotas go unfulfilled.7 The governments of these islands are trying to build adaptive capacity and employ migration as a means of improving the quality of life. The Kiribati government has implemented a program, entitled ‘Migration with Dignity’, which aims to create a skilled workforce that can find decent employment abroad. In 2014, the government also purchased 6,000 acres in Fiji to try and ensure food security whilst the environment changes.8 With support from the Green Climate Fund, the Tuvalu Coastal Adaptation Project will enhance resilience to coastal hazards on some of the nation’s islands.9
These measures might not be enough, but they are better than simply waiting for other countries to help. As Kiribati President, Taneti Maamau said: “We are telling the world that climate change impacts Kiribati, it’s really happening… But we are not telling people to leave.” 8 Rather than simply focusing on relocation – an option that does not support true self-determination for the affected people – international policy should provide adaptive capacity and long-term support to these island states. Many engineering options are available, such as coastal fortification, and land reclamation technologies. It is imperative, therefore, for developed countries to voluntarily adopt these measures before they are forced to do so.

A landmark case brought by six young Portuguese citizens in November 2020 against 33 signatory states to the 2015 Paris Agreement continues to gain momentum at the European Court of Human Rights (ECHR). In early May, the European Commissioner for Human Rights and a number of NGOs filed third party interventions to the Court in support of the applicants’ claim. Duarte Agostinho and Others v. Portugal and Others centers on the alleged violation of the applicants’ right to life (article 2) and right to respect for private and family life (article 8) as well as the prohibition of discrimination (article 14) due to the disproportional effects of climate change on younger generations. Due to the urgency of addressing climate change, the applicants won a legal battle confirming the court’s decision to fast-track the case.
The ECHR has constructed a notable body of case law which acknowledges the direct impact of certain environmental issues on human rights, and requires states to mitigate resulting violations of these rights. The ‘environmental admissibility criteria’ for the ECHR, established in Fadeyeva v Russia (2005), stipulates that interference on an applicant’s private life must be concrete and severe, a requirement which the applicants have already satisfied.
There is scientific and governmental consensus that climate change impacts human life, but a state’s legal obligation to mitigate the risk has yet to be established by the Court. By demonstrating causation between the defendant states’ greenhouse gas emissions and global warming induced heatwaves, the Duarte Agostinho case could set a new precedent for a state’s legal obligations to mitigate the effects of climate change. The third party interventions provide the Court with evidence linking national inaction on climate change to ensuing negative impacts on the applicant’s health and human rights.
The group of NGOs that recently filed supportive third party interventions includes Amnesty International, Climate Action Network (CAN) Europe, Germanwatch, Notre Affaire à Tous, and 2Celsius. These organisations have provided evidence supporting the claim that current national contributions will not reduce emissions to a level that will prevent global temperatures from rising above 2°C, in accordance with commitments of the Paris Agreement. According to Wendel Trio, Director of CAN Europe, “Current efforts by our governments to reduce greenhouse gas emissions are highly insufficient as the world is still heading for a temperature rise around 2.5°C, alarmingly above the objectives of the Paris Agreement.” The court should appreciate the expert knowledge on this subject as it waits for government defenses which are due by May 27th.
Refugee shelters are being destroyed as rains begin in Sudan. Thousands of Ethiopians fleeing violence in Tigray over the past few months have found themselves facing extreme weather conditions, from scorching heat to long rains.
Climate change is responsible for the unpredictable rainfall and high temperatures across Sudan’s arid and semi-arid areas. Sudan’s already vulnerable position has made combating climate change in the country difficult; conflict, poverty and displacement limit potential investment into climate mitigation or adaptation efforts.
The Sudanese government, the World Food Programme (WFP) and UN organisations (United Nations Development Programme), have made efforts to address the energy needs of refugees by creating sustainable conditions. For example, energy saving stoves and solar panels have been implemented to improve conditions for refugees. Plant drought-resistant plants are also providing food and greenery.
Despite such adaptation efforts, Sudan’s vulnerable position makes climate mitigation difficult. Preventative measures to protect refugees from further displacement and suffering are necessary to shield refugees from future floods and other climate disasters. Climate mitigation may only be possible in Sudan if vulnerability factors such as conflict and poverty are addressed, too.
On Tuesday 18th May, 2021, 6,000 migrants from Morocco swam and walked across the border to Spain. Video evidence showed Moroccan soldiers allowing migrants through security gates, sparking tensions between the two countries. The European Union stands in defence of Spain, condemning the mass incursion as a breach of borders. This comes following policy disputes over Western Sahara, which Spain maintains must be resolved via a United Nations agreement.
Migrants fled Morocco seeking economic opportunity, in pursuit of education or to flee poverty and human rights abuses. Unemployment in Morocco has been rising in recent years, with a significant rise of 2% as a result of the Covid-19 pandemic. Urban areas have been hit harder by unemployment compared to rural areas, although sectors across both have been affected. Whilst socio-economic crises and the pandemic are major causes of unemployment in Morocco, growing rural-urban migration – largely due to climate change, is also a factor.
Rising temperatures makes agricultural productivity more difficult. The High Commission for Planning (HCP) predicts that by 2050 only 15% of Morocco’s population will live in non-urban areas; this compares to 40% in 2018. With rural populations shrinking, (both water scarcity and floods causing a decline in agricultural production and an increase in poverty) a growing urban population needs employment.
Morocco has taken numerous commitments to combat climate change via adaptation initiatives such as the Green Generation 2020-2030 plan – to support the agricultural sector through water irrigation and reducing dependence on rain-fed farming. Water irrigation projects are expected to save 2.4bn metres of water by 2030. On-going protection of rural areas is vital for agricultural livelihoods that make up 34% of employment. The links between climate change, rural-urban domestic migration, unemployment and cross-border migration requires further investigation; such as the percentage of rural verses urban migrants leaving their home country, Morocco.
Climate-induced violence is rising in poverty-ridden regions across the earth, and women are being left in the shadows of its wrath.
In Sub-Saharan Africa, compounding variations in seasonality have resulted in an increased incidence of extreme weather events, acute environmental degradation, and a widespread decline in quality of life. With more than 95% of farmed land using rain-fed cultivation, these regions are heavily reliant on stable rainfall cycles to maintain annual agricultural yields. 1 In recent years, increasing severity in climate variability has magnified the intensity and frequency of flooding and drought, exacerbating issues of food insecurity and resource scarcity throughout the land.
Changes in climate disproportionately impact the livelihoods of women because they possess limited social control and ownership of land, and often serve as primary caregivers within their communities. They also face increased exposure to gender-based violence during periods of economic and environmental upheaval, as well as harmful discrimination in the labour market, making it difficult to generate alternative sources of income as needed.
Economic pressures have intensified with environmental disaster in many rural areas of Sub-Saharan Africa, driving hunger-based fatalities. In Angola, girls as young as the age of 12 are resorting to prostitution in order to avoid starvation. 2 Crisis coverage from the Thomas Reuters Foundation reports that “a girl might get 500 kwanzas ($1) for sex – enough to buy about a kilo of beans or two kilos of maize – but could get as little as 200 kwanzas.. Sometimes they earn as little as 5 RGT ($0.31) for one sexual encounter, which is .. not even enough to buy a loaf.” 3 These conditions simultaneously place girls at higher risk of sexual exploitation and human trafficking due to the subversive nature of the sex market.
In the Amboseli basin of southern Kenya, rising temperatures have caused rivers and grasslands to dry up, causing women and young girls to walk extensive distances to collect essential resources including firewood and water. 4 A field report conducted by the UN Africa Renewal program affirms that these tasks are both physically and mentally demanding, as it may take more than 20 hours per week to locate clean water, examine existing well levels, and carry the water home. 5 This process leaves young girls vulnerable to sexual assault and rape, whilst worsening the spread of infectious disease and infirmity within already weakened communities.
Environmental extremes also aggravate the prevalence of child marriage in various rural regions. The intensity and duration of recent dry spells have left countless families in dire need of basic resources, causing many to offer their daughters as brides to help ease financial stress. In rural districts of Malawi, “girls are forced sometimes to marry younger than 14. Some are impregnated by schoolteachers, some are forced to get married so the in-laws will bring bread and butter to their homes, others marry because of peer pressure. Especially when harvests are not good, these problems arise as girls are used to generate income.” 6
An increase in child marriage has further driven the practice of female genital mutilation (FGM), as this procedure is often carried out in preparation for marriage. Despite bans that have been implemented to prohibit both of these practices, researchers in northern Kenya have witnessed a climate-related surge in cases. 7 Throughout the 2020/2021 season, periods of prolonged drought were superseded by widespread locust outbreaks, resulting in deeper impoverishment and irreparable damage to livestock and crops. Despairing households succumbed to desperate measures, marrying off their daughters in exchange for dowries. 8
Girls who have undergone FGM are also perceived as more ‘valuable’ in comparison to those who remain uncut, inviting higher bride prices. Many families are able to circumvent the bans on these practices by shipping their daughters to neighboring countries where laws are less restrictive, and having them sent back prior to marriage. 9
In the absence of government intervention, rates of child marriage and FGM will continue to rise in synchronicity with environmental disaster and displacement. A severe lack of legal reinforcement and safeguarding services in regions across Sub-Saharan Africa is contributing to this endless cycle of gender-based violence. If vulnerable areas are left without stronger protection aid, this issue will only continue to worsen as levels of hunger and extreme weather events become more pervasive.
It is vital to draw deeper attention to the connections between climate change and violence against women and children in order to subvert the underground nature in which many of these practices are conducted. In addressing the impacts of climate-sensitive stresses, it is crucial to accentuate the various gender disparities inherent in a shifting ecological framework.

Climate activists from the youth climate group Sunrise Movement have been marching 400 miles from New Orleans to Houston, following the path of thousands of families who permanently fled New Orleans in the wake of Hurricane Katrina. The activists’ aim is to pressure President Biden into including a Civilian Climate Corps in his $2.26 trillion infrastructure plan, which will create good-paying jobs for young people within environmentally friendly careers.
Along the way the group is making stops in communities disproportionately affected by the climate crisis. At these stops the group will be holding protests and rallies, and will be joined by many figures including political leaders and environmental justice activists. One of these stops was St James parish, a community about an hour outside of New Orleans, where the group protested the proposed construction of a petrochemical complex. St James parish sits on an 85-mile industrial corridor along the Mississippi River, which has been dubbed “Cancer Valley” due to housing more than 150 chemical plants and oil refineries. Last year, the government approved permits for plastic company Formosa Plastics to build 14 plastic plants in St James parish.
Environmental justice group, Rise St James, has been leading the fight to block Formosa from building the facility in their community. The Sunrise Movement organised the protest along with Rise St James, to bring greater awareness to the issue. Researchers have found that if the proposed Formosa complex is built it would leave communities vulnerable to extreme flooding, due to the destruction of nearby wetlands. The facility is also expected to emit and discharge a variety of pollutants, including carcinogens, into the air and water. St James parish is a predominantly black community, and Varshini Prakash, the co-founder and executive director of Sunrise Movement, has described the situation as “the epitome of environmental racism”.

Daniel Briggs is an experienced ethnographer and social researcher who has studied some of the most disturbing and challenging social realities of the 21st century. He is currently a part-time Professor of Criminology at Universidad Europea, and an award-winning author in the field of Criminology.
In this conversation with Yumna, he discusses what ethnographic research entails, and what led him to research and write ‘Climate Changed: Refugee Border Stories and the Business of Misery’, an honest, humane account about the rapid downsizing of the world’s natural resources and the consequences this has for millions who are displaced from their home countries because of politically-instigated and economically-justified war and conflict. The book is centred upon interviews with 110 refugees who arrived into Europe from 2015-2018 and observations of refugee camps, border crossings, inner-city slums, social housing projects, NGO and related refugee associations. Briggs sets this against the geopolitical and commercial enterprise that dismantled refugees’ countries in the international chase for wilting quantities of the world’s natural resources.
“… i counted about [200 people] in [Basmane Square] … and there was a boy, probably 2 years of age at the time…playing with a [discarded] lifejacket as if it were a toy with which he didn’t know how to play… You realise that actually, these people want everything you or I want in life: a safe place for their family to live, a job, and to not be terrorised. And I just thought to myself, “My God, that kid has no idea what has happened in his home country, no idea why he is sitting on a dirty pavement playing with a lifejacket…it really brings it home”
