Shrinking shores: Half the world’s beaches could disappear because of climate change, study says

by Doyle Rice, USA Today

Bye-bye beaches?

Half of the world’s beaches could disappear by 2100 because of severe erosion linked to climate change, a study published Monday suggests.

The main causes are sea-level rise and erosion from storms, the study says, which warned of “the near-extinction of almost half of the world’s sandy beaches by the end of the century.”

Global Warming May Deprive Polar Bears of Safe Places to Give Birth

by Nala Rogers, Inside Science

Study suggests that if climate change continues unabated, there soon won’t be enough snow in northern Alaska for polar bears to dig birthing dens.

Polar bears are born into the Arctic winter blind, hairless, and no bigger than a guinea pig. For three months while storms rage and temperatures fall below -40 F, the cubs stay snug and warm in their mothers’ dens. But if current trends continue, newborn cubs along Alaska’s northern coast may instead perish out in the cold.

The ice we’ve lost to climate change this past decade, visualized

by Umair Irfan, Vox –

As polar and mountain regions have warmed, the extent of sea and land ice has declined.

One of the most poignant climate moments of 2019 was a funeral for ice: an August ceremony in Iceland for the country’s Okjökull glacier. As can be seen in these NASA satellite images, the glacier declined dramatically between 1986 and 2019: Continue reading The ice we’ve lost to climate change this past decade, visualized

Earth has had more major mass extinctions than we realized

by Lucy Jakub, National Geographic

All these periods of sudden, drastic species loss share patterns. That has worrying implications for the climate-driven losses we’re seeing now.

Today’s biodiversity crisis is often referred to as the “sixth mass extinction” by those who believe we’re headed for a collapse in global species counts. But perhaps, some scientists argue, we should be calling it the seventh.
