Rising Sea Levels = Rising Level of Concern

Global sea levels are rising, and yesterday’s video of melting glaciers in western Greenland is a stunning (albeit scary) example of its cause. Climate change isn’t going anywhere unless we act, and until we do, researchers will find new ways to demonstrate the damage happening every day. Here’s a recent study that spans over two decades.

Researchers at the Australian National University (ANU) found that the past century rivals sea levels not seen for thousands of years.  They used 1,000 sediment samples from Britain, North America, and Greenland to reconstruct 35,000 years of sea fluctuations, and measured an increase of about 20cm. This is unparalleled over a timespan of more than 6,000 years.

The ANU research results published in PNAS are consistent with other studies, including salt flat data changes in the sea floor due to extra water weight.

Rising temperatures are the culprit. With higher temperatures due to climate change, the polar ice melts and the sea expands. This is what you saw in the video yesterday – the cold hard facts caught on camera.

Scientists predict that this trend will continue for the next century. And that’s only if carbon emissions stay at the same level they are today.

Global warming affects the livelihoods of more and more people sometimes to such an extent that they have to leave their homes either temporarily or permanently, becoming environmental refugees.
