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.

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.

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.

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

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).

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.

An extensive new multi-proxy database of paleo-temperature time series (Temperature 12k) enables a more robust analysis of global mean surface temperature (GMST) and associated uncertainties than was previously available. We applied five different statistical methods to reconstruct the GMST of the past 12,000 years (Holocene). Each method used different approaches to averaging the globally distributed time series and to characterizing various sources of uncertainty, including proxy temperature, chronology and methodological choices. The results were aggregated to generate a multi-method ensemble of plausible GMST and latitudinal-zone temperature reconstructions with a realistic range of uncertainties. The warmest 200-year-long interval took place around 6500 years ago when GMST was 0.7 °C (0.3, 1.8) warmer than the 19th Century (median, 5th, 95th percentiles). Following the Holocene global thermal maximum, GMST cooled at an average rate −0.08 °C per 1000 years (−0.24, −0.05). The multi-method ensembles and th

Under current emission trajectories, temporarily overshooting the Paris global warming limit of 1.5 °C is a distinct possibility. Permanently exceeding this limit would substantially increase the probability of triggering climate tipping elements. Here, we investigate the tipping risks associated with several policy-relevant future emission scenarios, using a stylised Earth system model of four interconnected climate tipping elements.

The Center for Climate Integrity (CCI) helps communities hold oil and gas corporations accountable for the massive costs of climate change.
From farmers to disaster survivors, new plaintiffs and progressing lawsuits are putting pressure on industry polluters.
This report focuses on the 20 investors and 20 banks that are funding the methane generating activities of 15 of the leading meat and dairy companies worldwide. Collectively these financial institutions fund a methane footprint that could exceed 503 Mt CO2e – nearly as big as the CO2emissions of Saudi Arabia.
This report reveals the tactics of Big Meat and Dairy companies to delay, distract, and derail action on transforming the food system, mirroring strategies used by the tobacco and fossil fuel industries. Food systems are responsible for around a third of global greenhouse gas emissions, with approximately 60% coming from animal agriculture, the largest source of man-made methane emissions.

Simultaneous harvest failures across major crop-producing regions are a threat to global food security. Concurrent weather extremes driven by a strongly meandering jet stream could trigger such events, but so far this has not been quantified. Specifically, the ability of state-of-the art crop and climate models to adequately reproduce such high impact events is a crucial component for estimating risks to global food security. Here we find an increased likelihood of concurrent low yields during summers featuring meandering jets in observations and models. While climate models accurately simulate atmospheric patterns, associated surface weather anomalies and negative effects on crop responses are mostly underestimated in bias-adjusted simulations. Given the identified model biases, future assessments of regional and concurrent crop losses from meandering jet states remain highly uncertain. Our results suggest that model-blind spots for such high-impact but deeply-uncertain hazards have to be anticipated and acc

Abstract. Intergovernmental Panel on Climate Change (IPCC) assessments are the trusted source of scientific evidence for climate negotiations taking place under the United Nations Framework Convention on Climate Change (UNFCCC). Evidence-based decision-making needs to be informed by up-to-date and timely information on key indicators of the state of the climate system and of the human influence on the global climate system. However, successive IPCC reports are published at intervals of 5–10 years, creating potential for an information gap between report cycles. We follow methods as close as possible to those used in the IPCC Sixth Assessment Report (AR6) Working Group One (WGI) report. We compile monitoring datasets to produce estimates for key climate indicators related to forcing of the climate system: emissions of greenhouse gases and short-lived climate forcers, greenhouse gas concentrations, radiative forcing, the Earth's energy imbalance, surface temperature changes, warming attributed to human activit
