The rush to 'go electric' comes with a hidden cost: destructive lithium mining | Thea R... - 0 views

  • In order to stave off the worst of the accelerating climate crisis, we need to rapidly reduce carbon emissions. To do so, energy systems around the world must transition from fossil fuels to renewable energy. Lithium batteries play a key role in this transition: they power electric vehicles and store energy on renewable grids, helping to cut emissions from transportation and energy sectors. Underneath the Atacama salt flat lies most of the world’s lithium reserves; Chile currently supplies almost a quarter of the global market. But extracting lithium from this unique landscape comes at a grave environmental and social cost.
  • The entire process uses enormous quantities of water in an already parched environment. As a result, freshwater is less accessible to the 18 indigenous Atacameño communities that live on the flat’s perimeter, and the habitats of species such as Andean flamingoes have been disrupted.

  • we are on the verge of a global boom in mining linked to the energy transition
  • by 2040, the IEA forecasts that demand for lithium will have increased 42 times relative to 2020 levels
  • In the US and Europe, policymakers increasingly talk about a “race” to secure the minerals linked to energy transition and shore up domestic supplies; the idea of a “new cold war” with China is frequently invoked
  • natural resource sectors, which include extractive activities like mining, are responsible for 90% of biodiversity loss and more than half of carbon emissions. One report estimates that the mining sector produces 100bn tons of waste every year. Extraction and processing are typically water- and energy-intensive, and contaminate waterways and soil. Alongside these dramatic changes to the natural environment, mining is linked to human rights abuses, respiratory ailments, dispossession of indigenous territory and labour exploitation. Once the minerals are wrested from the ground, mining companies tend to accumulate profits and leave behind poverty and contamination. These profits only multiply along the vast supply chains that produce electric vehicles and solar panels. Access to these technologies is highly unequal, and the communities who suffer the harms of extraction are frequently denied its benefits.
  • battles between competing visions of a low-carbon world are intensifying – and they will become increasingly central to politics across the world
  • there are multiple paths to rapid decarbonisation
  • A transportation system based on individual electric vehicles, for example, with landscapes dominated by highways and suburban sprawl, is much more resource- and energy-intensive than one that favours mass transit and alternatives such as walking and cycling
  • Chilean activists are clear: there is no zero-sum conflict between fighting climate breakdown and preserving local environments and livelihoods. Indigenous communities in the Atacama desert are also on the frontlines of the devastating impacts of global heating. Rather than an excuse to intensify mining, the accelerating climate crisis should be an impetus to transform the rapacious and environmentally harmful patterns of production and consumption that caused this crisis in the first place

5 Things COP27 Must Achieve for Vulnerable Countries | World Resources Institute - 0 views

  • Vulnerable countries, despite their limited contribution to climate change and ambitious climate commitments, are and will continue to shoulder the bulk of this burden
  • Developed by organizations from the Global South, ACT2025’s new Call for Enhanced Implementation lays out where concrete action is needed in the lead-up to and at the conference.
  • When looking at countries’ commitments to reach net-zero emissions by around mid-century, temperature rise could be kept to around 1.9 degrees C. However, some major emitters’ 2030 targets are so weak that they don’t offer credible pathways to achieve their net-zero targets, indicating a major “credibility gap.”

  • All countries — especially G20 countries — that have submitted “updated” NDCs that were no more ambitious than their previous commitments, and countries that have not yet communicated new or updated NDCs at all, should update their NDCs and long-term strategies in a credible, ambitious manner
  • developed countries must lead on climate ambition — they are the laggards in living up to their climate promises despite their overwhelming contribution to the climate crisis
  • After COP26, it was noted “with deep regret” the failure of developed countries to meet the $100 billion goal they originally promised to achieve by 2020, feeding into the credibility gap and hamstringing the ability of developing countries to plan further climate action.
  • clear finance targets for mitigation, adaptation and loss and damage finance
  • $600 billion in climate finance from 2020-2025
  • The urgency for enhanced adaptation action is underscored by the IPCC Working Group II report, mentioned previously,  which finds that every tenth of a degree of additional warming will escalate threats to people, species and ecosystems. Yet many communities still lack the resources required to manage today’s climate change impacts, let alone worse impacts in the future.
  • countries must also prepare their National Adaptation Plans and Adaptation Communications
  • developed countries need to provide grant-based funding to finance adaptation plans, especially through the Adaptation Fund and other entities of the Financial Mechanism established under the UNFCCC.
  • despite an urgent plea from climate-vulnerable countries, the proposal for a new loss and damage financing facility was  rejected by developed nations. Instead, at COP26, countries established the Glasgow Dialogue to discuss possible arrangements for loss and damage funding, with the first discussion to be held in June 2022.
  • even the most effective adaptation measures cannot prevent all losses and damages, which are a present-day reality for vulnerable people in certain regions
  • Countries also made progress at COP26 on the operationalization and funding of the Santiago Network on Loss and Damage (SNLD), which aims to provide developing countries with technical assistance on how to address loss and damage in a robust and effective manner. Sufficient financing for the SNLD is crucial to ensure technical support for developing countries and to create a new method in encouraging technical assistance that is country-owned and emphasizes local expertise.
  • The first Global Stocktake process must be done in a way that is inclusive, raises awareness, ensures the meaningful participation of Global South organizations, and paves the way for a comprehensive outcome that promotes increased NDC ambition and is centered around equity. Additionally, the UN Secretary General should hold countries and non-state actors accountable to develop a robust accountability system for commitments made outside of the UNFCCC process.
  • Shortly after COP27, we will be more than a quarter of the way through the decisive decade — what will the world have to show for it? Now is the time for solidarity and ambitious, real, on-the-ground action and support that will deliver justice for vulnerable countries and communities. While realizing countries’ differentiated responsibilities and capacities, the world needs to be all in, all together on climate.

Drought may have doomed this ancient empire - a warning for today's climate crisis - Th... - 1 views

  • A new analysis published Wednesday in the journal Nature shows that the Hittites endured three consecutive years of extreme drought right around the time that the empire fell. Such severe water shortages may have doomed the massive farms at the heart of the Hittite economy, leading to famine, economic turmoil and ultimately political upheaval, researchers say.
  • n accumulating field of research linking the fall of civilizations to abrupt shifts in Earth’s climate. In the ruins of ancient Egypt, Stone Age China, the Roman Empire, Indigenous American cities and countless other locations, experts have uncovered evidence of how floods, droughts and famines can alter the course of human history, pushing societies to die out or transform.
  • It underscores the peril of increasingly frequent and severe climate disasters. But it also points to strategies that might make communities more resilient: cultivating diverse economies, minimizing environmental impacts, developing cities in more sustainable ways.

  • “Things like climate change, earthquakes, drought — they are of course realities of our lives,” Durusu-Tanrıöver said. “But there are human actions that can be taken to foresee what will happen and behave accordingly.
  • In the half-century leading up to empire’s collapse, the scientists found, the rings inside the tree trunks gradually start to get narrower — suggesting that water shortages were limiting the junipers’ growth. Chemical analyses of the kind of carbon captured in the wood also showed how drought altered the trees at the cellular level.
  • cuneiform tablets from that time in which Hittite officials fretted over rising food prices and asked for grain to be sent to their cities. But Manning said the empire — which was known for its elaborate water infrastructure projects and massive grain silos in major cities — should have been able to survive this “low frequency” drought.
  • between 1198 and 1196 B.C., the region was struck by three of the driest years in the entire 1,000-year-long tree ring record. The abrupt spurt of intensely dry weather may have been more than the Hittites could bear. Within a generation, the empire had dissolved.
  • “Very few societies ever plan for more than one or two disasters happening consecutively.”
  • “But I think it’s naive to believe that three years of drought would bring down the storerooms of the Hittite empire,” Weiss said. He argues that the longer-term drying trend, which has been documented in other studies, was probably more significant.
  • “What’s a crisis for some becomes almost an opportunity for others,” Manning said. “You have adaptation and resilience in the form of new states and new economies emerging.”
  • Durusu-Tanrıöver blames an unsustainable economy and centralized political system. The intensive agricultural practices required to support the capital city probably exhausted the region’s water resources and weakened surrounding ecosystems
