In the lead-up to COP29, Fausto Corvino emphasized the need for a paradigm shift within the international climate negotiations to ensure that the global rich bear a greater responsibility for climate finance. In this follow-up article, he explains why COP29 has failed in its historic mission to lay the foundations for a rapid and equitable global transition to low-carbon energy....

We are used to thinking about natural disasters as events confined in time and space: the direct impact in a certain location of an earthquake happens over minutes, a hurricane over hours. While they might be confined in geography, longitudinal studies can help us understand the full range of effects and what extra efforts might be needed to rebuild.

Average global temperature in November was 1.62C above preindustrial levels, bringing average for the year to 1.60C. Data for November from the EU’s Copernicus Climate Change Service (C3S) found the average global surface temperature for the month was 1.62C above the level before the mass burning of fossil fuels drove up global heating. With data for 11 months of 2024 now available, scientists said the average for the year is expected to be 1.60C, exceeding the record set in 2023 of 1.48C.

The new study, led by researchers at the Global Systems Institute, University of Exeter, associated with the Earth Commission, and Nanjing University, assessed what this would mean for the number of people living outside the “climate niche” in which our species has thrived. It says about 60 million people are already exposed to dangerous heat (average temperature of 29°C or higher). And two billion – 22% of the projected end-of-century population – would be exposed to this at 2.7°C of global warming.

Op de vijfde top van het Intergovernmental Negotiating Committee on Plastic Pollution in Busan, Zuid-Korea, is geen akkoord uit de bus gekomen. Het comité van het VN-Milieuprogramma moet de plasticproductie aan banden te leggen, maar de weerstand van de olieproducerende landen bleek te groot.

On why collapse could be much closer than predicted: what happens when the Atlantic Ocean’s heart stops beating?

To tackle the challenges of competitiveness and well-being of future generations, Europe needs to accelerate the climate transition. This will require sizable investment, both public and private. National governments must thus embrace and the EU must facilitate investments in climate transition.

Trump could reverse the nation’s progress on climate change, but rolling back the Biden administration’s significant climate successes could be a low, slow and difficult process...

In het Zuid-Koreaanse Busan leggen delegaties uit 175 landen de laatste hand aan een nieuw verdrag tegen plasticvervuiling, ondanks tegenstand van olieproducerende landen.

Top officials in Baku for COP29 say the spread of false climate narratives undercuts the annual climate talks.

This research reinforces the scientific consensus that the only viable strategy to limit catastrophic climate change requires drastic and immediate emissions cuts. An important study was published last month in the journal Nature, titled “Overconfidence in climate overshoot.” While increasingly dire warnings of the catastrophic impacts of global climate change continue to be published by scientists, the findings of this new paper provide another stark reminder of the urgent necessity to limit global warming by immediately reducing greenhouse gas (GHG) emissions.

The idea that the AMOC is headed to collapse is very controversial, but it is clearly weakening. If the circulation did collapse, the consequences on both sides of the Atlantic Ocean would be immense—including large changes in temperature and a spike in weather-related disasters.

Disruption of the Atlantic Meridional Overturning Current could freeze Europe, scorch the tropics and increase sea level rise in the North Atlantic. The tipping point may be closer than predicted in the IPCC’s latest assessment.

04/17/2024 - Even if CO2 emissions were to be drastically cut down starting today, the world economy is already committed to an income reduction of 19 % until 2050 due to climate change, a new study published in “Nature” finds. These damages are six times larger than the mitigation costs needed to limit global warming to two degrees. Based on empirical data from more than 1,600 regions worldwide over the past 40 years, scientists at the Potsdam Institute for Climate Impact Research (PIK) assessed future impacts of changing climatic conditions on economic growth and their persistence.

Op de VN-klimaattop in Bakoe zijn belangrijke besprekingen over uitstootreductie in de eerste week op een haar na gekelderd door verzet van oliestaat Saoedi-Arabië en enkele ontwikkelingslanden. Het voorzitterschap moest alle zeilen bijzetten om de onderhandelingen uit het slop te halen.

Global warming has already caused the Arctic to release more climate-warming methane—but exactly how much will depend closely on the actions we take to halt climate change.

Insurance costs are rising quickly across much of the country. Hurricanes are part of the reason, but it’s the other perils common across the Midwest and Great Plains that complicate costs.

The results of one election can’t stop the momentum of the energy transition. But they can do a lot of damage.

A Trump presidency can delay, but not stop, the global transition to renewable energy, but it may more effectively stymie progress than during his first term.

A new declaration aims to make the southernmost continent an autonomous legal entity, akin to a nation-state, with inherent rights to participate in decision making that affects it.

The election of Donald Trump as president for a second time and the Republican takeback of the U.S. Senate could undo many of the national climate policies that are most reducing planet-warming greenhouse gas emissions, according to climate solutions experts.When they list measures that are making the most difference, it lines up with policies Trump has said he’ll target. These rollbacks will come as more lives are being lost in heat waves, record amounts of climate pollution are accumulating in the atmosphere, the United States has been hit with what may be two of its most expensive hurricanes, and nations, which will meet in Baku, Azerbaijan next week for climate negotiations, have failed to take strong action to change these realities.

Without urgent action, Earth is heading for climate catastrophe. Yet there are reasons for hope in 2024 – including a possible peak in global greenhouse gas emissions.

The predicted El Niño is a worry, but it doesn’t guarantee the record-breaking heat we’re seeing in parts of the Northern Hemisphere.

UN Climate Change Conference Baku - November 2024 | UNFCCC

Oceanographer Stefan Rahmstorf explains why Amoc breakdown could be catastrophic for both humans and marine life

If despair is the most unforgivable sin, then hope is surely the most abused virtue. That observation feels particularly apposite as we enter the Cop season, that time of United Nations megaconferences at the end of every year, when national leaders feel obliged to convince us the future will be better, despite growing evidence to the contrary.

Abstract. We review how the international modelling community, encompassing integrated assessment models, global and regional Earth system and climate models, and impact models, has worked together over the past few decades to advance understanding of Earth system change and its impacts on society and the environment and thereby support international climate policy. We go on to recommend a number of priority research areas for the coming decade, a timescale that encompasses a number of newly starting international modelling activities, as well as the IPCC Seventh Assessment Report (AR7) and the second UNFCCC Global Stocktake. Progress in these priority areas will significantly advance our understanding of Earth system change and its impacts, increasing the quality and utility of science support to climate policy. We emphasize the need for continued improvement in our understanding of, and ability to simulate, the coupled Earth system and the impacts of Earth system change. There is an urgent need to investiga

Critical tipping points in the climate system are the flies in the ointment when it comes to accurate prediction of where our planet is headed

These powerful ‘rivers in the sky’ provide a huge share of annual precipitation in many regions, including California. They can also melt sea ice, with global climate implications.

The big question: Would climate engineering like sending reflective particles into the stratosphere or brightening clouds help reduce the national security risks of climate change or make them worse?

Surpassing 1.5°C of warming can be undone at a later date – using tech, land and resources that don’t exist.

Climate change should be at the heart of national security plans, say experts.

Record emissions, temperatures and population mean more scientists are looking into possibility of societal collapse, report says

We are on the brink of an irreversible climate disaster. This is a global emergency beyond any doubt. Much of the very fabric of life on Earth is imperiled. We are stepping into a critical and unpredictable new phase of the climate crisis. For many years, scientists, including a group of more than 15,000, have sounded the alarm about the impending dangers of climate change driven by increasing greenhouse gas emissions and ecosystem change (Ripple et al. 2020).

To analyze the climate change experienced in Spain between 1971 and 2022 and to estimate the future climate for 2050.

VN-klimaatbaas Simon Stiell roept wereldleiders op om ‘het script om te gooien’ als het gaat om klimaatmaatregelen in Afrika. Hij wil de ‘epidemie van onderinvestering’ ombuigen naar een ‘goudmijn voor de Afrikanen en hun economie’.

The EU is being sued for failing to set ambitious climate targets in sectors that contribute more than half of the bloc’s total greenhouse gas emissions.

For many of us the climate crisis mainly calls to mind rising global temperatures, but the crisis goes far beyond this – we are at risk of pushing our planet across climate ‘tipping points,’ critical thresholds where small changes can lead to abrupt and irreversible shifts in the Earth’s climate system. One major element in climate tipping is a huge system of ocean currents, the Atlantic Meridional Overturning Circulation (AMOC), which is responsible for Europe's relatively mild climate. Past climate patterns show that these currents can switch abruptly between today’s vigorous flow and a much weaker flow state. A future shutdown would have potentially devastating consequences in Europe and around the world.

High-level policy discussions have built momentum for “food system transformation” that would help farmers address the climate crisis.
