As climate risks worsen, U.S. flood buyouts fail to meet the need

The U.S. approach to buying out properties vulnerable to flooding is rife with uncertainty and delays. Now, as climate change drives more extreme coastal storms and precipitation events, the system must undergo a drastic overhaul or risk stranding millions in flood-prone homes.

A huge iceberg just broke off West Antarctica’s most endangered glacier

On the ice-covered edge of a remote West Antarctic bay, the continent’s most imperiled glaciers threaten to redraw Earth’s coastlines. Pine Island Glacier and its neighbor Thwaites Glacier are the gateway to a massive cache of frozen water, one that would raise global sea levels by four feet if it were all to spill into the sea. And that gateway is shattering before our eyes.

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.
