Ice formation in Antarctica (stock image).Credit: © Lorraine Kourafas / Adobe Stock Inland Antarctic ice contains volumes of water that can raise global sea levels by several metres. A new study published in the journal Nature shows that glacier ice walls are vital for the climate, as they prevent rising ocean temperatures and melting glacier ice.advertisement The ocean […]Read More Antarctic ice walls protect the climate
Aerosol emissions from burning coal and wood are dangerous to human health, but it turns out that by cooling the Earth they also diminish global economic inequality, according to a new study by Carnegie’s Yixuan Zheng, Geeta Persad, and Ken Caldeira, along with UC Irvine’s Steven Davis. Their findings are published by Nature Climate Change.advertisement Tiny […]Read More Do the climate effects of air pollution impact the global economy?
Using computer simulations of a model by US Nobel Laureate William Nordhaus, researchers weight climate damages from, for instance, increasing weather extremes or decreasing labor productivity against the costs of cutting greenhouse gas emission by phasing out coal and oil. Interestingly, the economically most cost-efficient level of global warming turns out to be the one […]Read More Climate costs smallest if warming is limited to 2°C

One study predicted that crop yield lost to insects increases 10 to 25 percent for every 1 degree Celsius increase.advertisement Michigan State University scientists think […]Read More Insect bites and warmer climate means double-trouble for plants
Thermometer in snow (stock image).Credit: © weyo / Adobe Stock In October this year, weather researchers in Utah measured the lowest temperature ever recorded in the month of October in the US (excluding Alaska): -37.1°C. The previous low-temperature record for October was -35°C, and people wondered what had happened to climate change.advertisement Until now, climate researchers […]Read More Climate signals detected in global weather
A study in Botswana by Columbia University Mailman School of Public Health scientists finds that spikes in cases of life-threatening diarrhea in young children are associated with La Niña climate conditions. The findings published in the journal Nature Communications could provide the basis for an early-warning system that would allow public health officials to prepare for periods […]Read More Scientists link La Niña climate cycle to increased diarrhea
