A Changing Jet Stream

Climate Changes

Climate change appears to be affecting the jet stream, altering the weather patterns over the U.S. so that regions can get “stuck” in extreme weather for weeks, a new study has found. The jet stream is the fast-moving, high-altitude air current that shuttles weather from west to east over North America and Europe. But the pronounced warming of the Arctic—where […]

Carbon rise keeps water in drylands

The drylands of the world are getting greener, and researchers think it is thanks to higher levels of carbon dioxide in the atmosphere. In a paradoxical discovery, even as landscapes become increasingly at risk of desertification, they may also look more luxuriant. Two scientists from Purdue University in Indiana, US, and a researcher in Saudi Arabia report in the journal […]

Climate risk to inflexible penguins’ chicks

Crested and rockhopper penguins are threatened by climate change – but this time the penguins could be at risk because they cannot change their own ways. Evolution has left them with a rigid parenting strategy, probably well adapted for climate conditions so far. But as temperatures rise, conditions change and food supplies become precarious, the inflexible roles of male and female […]

New framework sheds light on how, not if, climate change affects cold-blooded animals

Cold-blooded animals like lizards, insects and fish have a preferred body temperature range at which they hunt, eat, move quickly and reproduce. Fear that a warming climate will constrict this temperature range underlies recent studies that warn of the detrimental effects of climate change on the activity and survival of cold-blooded animals. While not contradicting these warnings, a new paper […]

Impact of human activity on local climate mapped

Earth’s temperature has increased by 1°C over the past century, and most of this warming has been caused by carbon dioxide emissions. But what does that mean locally? A new study published in Nature Climate Change pinpoints the temperature increases caused by CO2 emissions in different regions around the world. Using simulation results from 12 global climate models, Damon Matthews, […]

Pope Francis’ Tough Stance On Climate Change

Pope Francis

In 2015, Pope Francis, the leader the Catholic Church, issued the first-ever comprehensive set of Vatican teachings on climate change, in the form of an encyclical—or “papal letter”—sent to churches worldwide. Plans also include personally lobbying for climate action action in a series of high profile meetings ahead of the all-important UN global warming negotiations in Paris. A papal letter […]
