The word “science,” according to Wikipedia, is derived from the Latin verb “scire, meaning ‘to know,’ specifically its present participle sciens, meaning ‘knowing.’” The root word scire is also connected to English words like conscience — shared knowledge of right and wrong — and omniscient — all-knowing. My, how times … [continued]
Attributable days of heat stress for different age cohorts (columns), at different warming levels (rows). Each circle contains 100 coloured dots, with each dot representing 1% of the age cohort. Darker dots indicate more heat-stress days. Source: Pietroiusti et al (2026).
By Ayesha Tandon More than 40% of children under the age of 10 globally are already experiencing at least 20 additional “heat-stress days” due to climate change. This is according to a new attribution study, published in Science Advances, which combines climate models with demographic data to assess the age groups and regions … [continued]
Balcony and rooftop solar could cover home cooling costs, if policy makers prioritize access SACRAMENTO — California is experiencing more frequent and dangerous heat days, but sky-high utility bills mean millions of people can’t afford to run air conditioning that could keep them safe, a new Environmental Working Group report … [continued]
Seven US states rely on the water in the Colorado River. Those seven states are divided into upper basin states — Colorado, New Mexico, Utah, and Wyoming — and lower basin states — Arizona, Nevada, and California. In 1922, the American southwest was little more than an arid area with … [continued]
Heatwaves are becoming more likely and more intense due to climate change, impacting sources of power generation around the world as they work to meet increased demand. When temperatures soared past 40C in parts of Europe in June and July 2026, nuclear reactors shuttered, gas plants’ efficiency fell, wind speeds dropped and … [continued]
By Irene Sans, Yale Climate Connections The Eastern Pacific continues to be very active. This is very typical for this time of year — and especially in seasons like this one, with an El Niño event strengthening — and with record-setting sea-surface temperatures, the activity is not expected to stop … [continued]
Changes in the Earth’s climate can be measured by satellites and sensors in the ocean, but they are hard for ordinary people to visualize — which makes them easy to ignore. Wildfires, on the other hand, do a splendid job of focusing our attention on the situation. Here is a … [continued]
France and Spain are enduring mammoth wildfires that threaten entire cites. More than 300,000 people have been displaced from their homes by the fires. Do you have any idea what sort of family trauma that causes? No income for most, no cooking facilities or clean bathrooms, no safe place for … [continued]

The planet is heating up more quickly than ever before. For decades, greenhouse gas emissions caused by human activity have been building up in the atmosphere and trapping ever-higher levels of heat. The resulting asymmetry between incoming solar energy and energy radiated back out into space — known as “Earth’s … [continued]
