Arctic ice melt is changing ocean currents

A major ocean current in the Arctic is faster and more turbulent as a result of rapid sea ice melt, a new study from NASA shows. The current is part of a delicate Arctic environment that is now flooded with fresh water, an effect of human-caused climate change.

What’s the ozone hole got to do with warming?

Based on new data crunched in climate model, researchers argue that CFCs are likely what’s caused the Arctic to warm even faster than the rest of the planet under the influence of climate change. CFCs are, after all, potent greenhouse gases.

Antarctica logs highest temperature on record of 18.3C

A record high temperature of 18.3C (64.9F) has been logged on the continent of Antarctica. The temperature was recorded in the Antarctic Peninsula, on the continent’s north-west tip – one of the fastest-warming regions on earth.

Why clouds are the key to new troubling projections on warming

Recent climate models project that a doubling of atmospheric CO2 above pre-industrial levels could cause temperatures to soar far above previous estimates. A warming earth, researchers now say, will lead to a loss of clouds, allowing more solar energy to strike the planet.

In the Afro-Caribbean heart of Puerto Rico, locals fight erosion

The waves crashed loudly on the collapsed ruins of the Paseo del Atlántico, a walkway that once partially protected residents here from the volatile ocean. Erosion along this northernmost coast of Puerto Rico, nearly 20 miles east of San Juan, precipitated the promenade’s destruction, it finally fell into the Atlantic, exposing the Parcelas Suárez neighborhood to the water’s edge.
