Despite working on polar science for the British Antarctic Survey for 20 years, Louise Sime finds the magnitude of potential sea-level rise hard to comprehend

Real world measurements of how much extra heat the Earth is trapping are well beyond most climate models. That’s a real problem.

Since Donald Trump's presidential election victory, major tech companies have abandoned years of policies restricting military work and sought out lucrative defense contracts and deeper connections with the Pentagon.

Breaching threshold would ramp up catastrophic weather events, further increasing human suffering

Fifteen years ago, smack in the middle of Barack Obama's first term, amid the rapid rise of social media and a slow recovery from the Great Recession, a professor at the University of Connecticut issued a stark warning: the United States was heading into a decade of growing political instability.

A new study uncovers Earth’s deep temperature history and shows just how tightly carbon dioxide has always controlled the climate

Russia’s war in Ukraine has encouraged a rapid increase in the deployment of drones that use fibre optic cables to protect them from being jammed or downed by electronic warfare: the drones trail kilometres of plastic cable across frontlines. In this post Leon Moreland explores the environmental risks posed by this new form of battlefield plastic pollution.

Earth’s albedo (reflectivity) declined over the 25 years of precise satellite data, with the decline so large that this change must be mainly reduced reflection of sunlight by clouds. Part of the cloud change is caused by reduction of human-made atmospheric aerosols, which act as condensation nuclei for cloud formation, but most of the cloud change is cloud feedback that occurs with global warming. The observed albedo change proves that clouds provide a large, amplifying, climate feedback. This large cloud feedback confirms high climate sensitivity, consistent with paleoclimate data and with the rate of global warming in the past century.

2024 marks the first time since record keeping began that all of the 10 hottest years have fallen within the most recent decade.

The world is warming despite natural fluctuations from the El Niño cycle.
