The big melt: Antarctica’s retreating ice could re-shape Earth

CAPE LEGOUPIL, ANTARCTICA: From the ground in this extreme northern part of Antarctica, spectacularly white and blinding ice seems to extend forever. What can’t be seen is the battle raging thousands of feet below to re-shape Earth. Water is eating away at the Antarctic ice, melting it where it hits the oceans. As the ice sheets slowly thaw, water pours […]

Warming oceans killing coral reefs

Coral reefs around the world are experiencing a massive die-off that could be the worst in recorded history, a new study warns. Stoked by climate change and a powerful El Nino, record-high ocean temperatures have triggered the global event, which began last year and is expected to destroy 5 percent of the world’s coral reefs by 2016. The temperature changes […]

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, […]

Warming adds to pressure on bats

Across the world, bats are in trouble from climate change – not only through collisions with the wind turbines that are intended to mitigate its effects, but from what the increasing warmth does to their ability to find their prey. Bats often get a bad press, portrayed as disease-spreading bloodsuckers. In fact, they perform a vital role as pollinators, seed […]

Antarctic ice sheet is more vulnerable to carbon dioxide than expected

Results from a new climate reconstruction of how Antarctica’s ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric CO2 than previously thought. Details appear in two […]

Humans settled, set fire to Madagascar’s forests 1,000 years ago

There’s no question that our species has had a dramatic impact on the planet’s physical environment, particularly over the last few centuries, with the rise of modern industry, transportation, and infrastructure. But as new research shows, humans have been transforming the landscape, with lasting impacts, since long before the start of the Industrial Era. Scientists from MIT and the University […]

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 […]
