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]
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]
Left: Observed changes in the Earth heat inventory for the period 1971–2020. Right: Estimates of the Earth energy imbalance for successive overlapping 20-year periods and the most recent decade (right). Shaded regions indicate the very likely range (90–100 % probability), while the stars show the CERES (NASA Clouds and the Earth’s Radiant Energy System) estimates for comparison.

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]

I was a bad friend the other day. As I was walking my local beach on a bright sunny day, I thought of my Connecticut pal who’ll be arriving here in Florida at the end of the month. I sent along a “Can’t way to see you” text with a … [continued]
Renewable energy is moving ahead all around the world, while the US sucks its thumb and whines about how good things were in the 1950s.
It’s hot across much of the US and Europe this week, as record temperatures sear hundreds of cities and millions of people.
The global energy system may be faced with an inescapable trade-off between urgently addressing climate change versus avoiding an energy shortfall, according to a new energy scenario tool developed by University of South Australia researchers and published in the open access journal Energies. The Global Renewable Energy and Sectoral Electrification model, dubbed ‘GREaSE’, … [continued]
According to my grandfather, “Only fools and newcomers try to predict the weather around here.” in the American Southwest. And, should anybody try to predict the weather, he’ll remind us that we aren’t newcomers, leaving only one other option. But, I’ve learned over time that his advice largely applies to … [continued]
The climate debate focuses on certain temperature increases, but one scientist suggests that is the wrong way to get people to act.
