Climate models simulate a wide range of 21st century warming for a given forcing scenario. Constraining this uncertainty is a central challenge in climate science because of its implications for climate policy and adaptation. The transient climate response (TCR) is a key idealized metric used to quantify future warming in response to an exponentially increasing CO2 concentration. Climate models span a range of 1.3–3 K for TCR. In attempts to constrain this range, emergent constraints on TCR based on historical temperature trends consistently pointed toward TCR values at the lower end of the range of models. However, recent evidence from trends in the short-wave and long-wave components of Earth's energy imbalance (EEI) at the top-of-atmosphere suggests that models with higher TCR lie closer to the observed EEI trends. Here, we reconcile this discrepancy and provide a revised range for TCR of 1.9–2.6 K. Using a statistical variability-filtering approach, we show that previous temperature-based constraints wer

Rising temperatures are set to drive up emissions from wildfires, fermenting wetlands, and melting permafrost, but these feedback loops are poorly captured in climate models. Scientists are racing to make sense of these emissions to gauge how much warming may lie ahead.

Some have called for Nuremberg-style trials against big oil. But there are laws already on the books to describe companies’ conduct

Emerging climate extremes should draw public attention to human-caused climate change. We expect unusual sea surface temperature (SST) and global warming the rest of this year to make 2026 hotter than 2024, despite 2024 being a peak El Nino year, while 2026 is only the lead-in year of an emerging El Nino. Beware the “surprise” record high being blamed on an extreme El Nino on top of global warming otherwise consistent with IPCC estimates. Instead, record warmth provides additional evidence of high climate sensitivity and increased net climate forcing in the past decade. These two factors are driving an unusual increase in global SSTs with major consequences. If you bear with our discussion to the end, you will find some possible good news.

European scientists warn of consequences for weather patterns, the global climate and marine life

The climate and nature crisis threatens all aspects of British life, from national security to the food supply. Despite the scale of the risks now facing the UK, there has been no comprehensive national emergency briefing delivered to the public by the Government.

Study also finds high humidity means people in hundreds of cities are enduring their worst ever heat stress

Food security (FS) remains a pressing issue at the global scale. Current literature about FS points to a plethora of causes of food insecurity, among which climate change and the loss of biodiversity are critical to all facets of food security. Building on this notion, we advocate for a comprehensive understanding of drivers of food security, thus contributing by examining climate change and biodiversity as drivers of food security. The interest in this subject stems not only from the scientific community, but also from practitioners and policymakers. However, holistic encapsulation of the relevant literature addressing this subject is currently lacking. This review systematically analyses and categorises the drivers of FS induced by climate change and biodiversity. Following the Systematic Literature Review approach, 342 peer-reviewed studies were selected and synthesised. Our findings identified 11 categories of climate change drivers and 9 categories of biodiversity drivers of FS. These drivers were found
