In a new paper, Sir Nicholas Stern, Nobel Laureate Joseph E. Stiglitz and Charlotte Taylor conclude that climate-energy-economy Integrated Assessment Models (IAMs), which are the key tool in producing emission-reduction scenarios, “have very limited value in answering the two critical questions” of the speed and nature of emissions reductions and “fail to provide much in the way of useful guidance, either for the intensity of action, or for the policies that deliver the desired outcomes”. The research paper is The economics of immense risk, urgent action and radical change: towards new approaches to the economics of climate change. Now this is a big thing, because IAMs are at the center of the IPCC Working Group III report on mitigation, and “have played a major role in IPCC reports on policy, which, in turn, have played a prominent role in public discussion.
Policies in place to reduce emissions as of December 2020 would lead the planet to 3.2 degrees Celsius of warming, more than double the 1.5 degrees limit that scientists say is essential for avoiding the worst impacts of the climate crisis. That’s the urgent warning from the latest Intergovernmental Panel on Climate Change (IPCC) report released Monday. “The jury has reached the verdict, and it is damning,” UN Secretary-General António Guterres told reporters ahead of the report’s release. “This report of the Intergovernmental Panel on Climate Change is a litany of broken climate promises. It is a file of shame, cataloging the empty pledges that put us firmly on track towards an unlivable world. We are on a fast track to climate disaster.
Scientists have long warned that time is of the essence to stop emitting greenhouse gases into the atmosphere. Now, in a new international report released on Monday, they argue the clock is also ticking on efforts to adapt to the devastating consequences of climate change. Rising seas, scorching wildfires, and devastating droughts already jeopardize billions of people worldwide — these, and other climate impacts, are expected to get much worse over the coming decades. “Any further delay” in global action, the report says, “will miss a brief and rapidly closing window of opportunity to secure a liveable and sustainable future for all.” The new report is the second of three parts of the latest global assessment by the Intergovernmental Panel on Climate Change, or IPCC, a body of leading climate experts from around the world.
A leaked draft of the third part of the upcoming IPCC report establishes that we must move away from the current capitalist model to avoid exceeding planetary limits. It also confirms that, as stated in the article published by CTXT on August 7, “Greenhouse gas (GHG) emissions must peak in at most four years”. The document also acknowledges that there is little chance of further economic growth. The signatories of this article, scientists and journalists, have analysed a new part of the Sixth Report, leaked by the scientists’ collective Scientist Rebellion and Extinction Rebellion Spain. The leak clearly shows the vast discrepancies between the scientific community’s understanding of what is needed to achieve an effective and just transition, and the reality of how little has been achieved.
President Joe Biden has been touring climate-ravaged areas of America, warning that climate change is a “code red” emergency for the planet. And yet, his administration has continued to boost fossil fuel projects and is now preparing to vastly expand offshore drilling. The White House argues that a court order it opposes and is appealing requires federal officials to lease more than 78 million acres of the Gulf of Mexico for fossil fuel exploration. Environmental groups, however, assert that federal law gives the administration broad discretion over whether or not to hold such sales. In fact, Biden’s officials have instead used that power to officially declare that the warnings in the recent Intergovernmental Panel on Climate Change (IPCC) report “does not present sufficient cause" to reevaluate the drilling plan.
In late March 2021, 120 traditional owners from 40 different First People’s groups spent five days at the National First People’s Gathering on Climate Change in Cairns (Australia). Speaking on the impact of the climate crisis on First People, Gavin Singleton from the Yirrganydji traditional owners explained that ‘From changing weather patterns to shifts in natural ecosystems, climate change is a clear and present threat to our people and our culture’. Bianca McNeair of the Malgana traditional owners from Gatharagudu (Australia) said that those who attended the gathering ‘are talking about how the birds’ movements across the country have changed, so that’s changing songlines that they’ve been singing for thousands and thousands of years, and how that’s impacting them as a community and culture.
The UN-sponsored Intergovernmental Panel on Climate Change (IPCC) recently released its latest comprehensive report on the state of the earth’s climate. The much-anticipated report dominated the headlines for a few days in early August, then quickly disappeared amidst the latest news from Afghanistan, the fourth wave of Covid-19 infections in the US, and all the latest political rumblings. The report is vast and comprehensive in its scope, and is worthy of more focused attention outside of specialist scientific circles than it has received thus far. The report affirms much of what we already knew about the state of the global climate, but does so with considerably more clarity and precision than earlier reports.
The United Nations Intergovernmental Panel on Climate Change’s sixth assessment report, released on Monday, contained some of the group’s strongest language yet affirming the link between human activity and global warming. Humans have “unequivocally” warmed the planet, the IPCC report said, making heatwaves, droughts, and wildfires more extreme in the process. While that might seem like a no-brainer to some, it’s a finding that could have big implications for lawsuits seeking to hold polluters accountable for disaster damages. “The IPCC report should be a sort of rallying call to lawyers,” said Rupert Stuart-Smith, a climate researcher at the University of Oxford, “to ensure that they are making use of the most up-to-date developments in climate science.”
Earth has warmed 1.09℃ since pre-industrial times and many changes such as sea-level rise and glacier melt are now virtually irreversible, according to the most sobering report yet by the Intergovernmental Panel on Climate Change (IPCC). The report also found escape from human-caused climate change is no longer possible. Climate change is now affecting every continent, region and ocean on Earth, and every facet of the weather. The long-awaited report is the sixth assessment of its kind since the panel was formed in 1988. It will give world leaders the most timely, accurate information about climate change ahead of a crucial international summit in Glasgow, Scotland in November. The IPCC is the peak climate science body of the United Nations and the World Meteorological Organization.
To coincide with the release of the 6th Assessment Report from the IPCC this morning, Extinction Rebellion UK has launched plans for 2 weeks of civil disobedience in London, beginning Monday 23 August. Because the future we fear is already here and there’s nothing left to do now but act. On impacts, the IPCC confirms what has become obvious: from heatwaves, to flooding, to droughts, every region on Earth is experiencing unprecedented weather extremes because of the CO2-jacked climate. Tropical cyclones are also intensifying and moving north. The IPCC also confirms that the land and oceans are on course to be – if they aren’t already – a net source of carbon emissions even in the lowest possible emissions scenario. The Earth’s carbon drawdown ability which has bailed us out for so long is hugely weakened.
Amidst a summer of fires, floods and heat waves, scientists on Monday delivered yet another reminder that burning more fossil fuels in the decades ahead will rapidly intensify the impacts of global warming. Only pulling the emergency brake right now on greenhouse gas emissions can stop the planet from heating to a dangerous level by the end of the century, the scientists’ report concluded. The report, Climate Change 2021: the Physical Science Basis, is the first installment of the Intergovernmental Panel on Climate Change’s Sixth Assessment Report (AR6), which will be completed in 2022. It was approved Aug. 6 by 195 member governments of the IPCC. The report, by the panel’s Working Group I, assesses the physical science of climate change. It found that global warming is worsening deadly extremes like droughts and tropical storms and that every part of the planet is affected.
The western states have been stuck in a blast furnace of hot weather as spring transitions to summer. Record-breaking heat, drought and extreme stress to power grids have almost half the country in deep distress. The last couple of days have seen a small reprieve, but that’s about to end. “The National Weather Service is warning of a ‘Record-Breaking and Dangerous Heatwave’ hitting this weekend and early next week,” reports Brian Kahn for Gizmodo. “Weather models are also coalescing around blistering heat. If the forecasts come to fruition, we’re not just talking about a few daily records falling here and there. We’re talking about a heat wave for the ages that could absolutely destroy all-time records from Washington to California as well as parts of Canada.”
Agence France-Presse reported Monday on the contents of a leaked draft of a United Nations intergovernmental climate panel report which warned that devastating effects of a warming world are set to hit far sooner than previously thought, with impacts including an additional tens of millions of people facing hunger by 2050. "This is a warning of existential risk. Of survival. Of collapse," said climate movement Extinction Rebellion in response to AFP's reporting on what the draft contained. The draft Intergovernmental Panel on Climate Change (IPCC) document warns of sweeping impacts on weather events, food, ecosystems, and disease—changes expected even if global temperature rise is kept under the Paris climate agreement's second threshold of 2°Celsius.
The world’s leading climate scientists have warned there is only a dozen years for global warming to be kept to a maximum of 1.5C, beyond which even half a degree will significantly worsen the risks of drought, floods, extreme heat and poverty for hundreds of millions of people. The authors of the landmark report by the UN Intergovernmental Panel on Climate Change (IPCC) released on Monday say urgent and unprecedented changes are needed to reach the target, which they say is affordable and feasible although it lies at the most ambitious end of the Paris agreement pledge to keep temperatures between 1.5C and 2C.
This week, scientists and representatives from every country on Earth are gathering in South Korea to put the finishing touches on a report that, if followed, would change the course of history. The report is a roadmap for possible ways to keep climate change to 1.5 degrees C above pre-industrial levels. Anything beyond that amount of warming, and the planet starts to really go haywire. So the Intergovernmental Panel on Climate Change — a U.N.-sponsored, Nobel Peace Prize-winning assemblage of scientists — wants to show how we can avoid that. To be clear, hitting that goal would require a radical rethink in almost every aspect of society. But the report finds that not meeting the goal would upend life as we know it, too.
