Earth Wise ·

2024/03/08

In an average year, the Great Lakes end up about 40% covered in ice. But this is not an average year. 2023 was the warmest year on record and, in fact, the global temperature was more than 1.5 degrees above the pre-industrial average for the full year. That hasn’t happened before. As a result of […]

Polar bears and the changing climate

Earth Wise ·

2024/03/07

The changing climate poses a major threat to polar bear survival. Polar bears, whose native range lies largely within the Arctic Circle, depend on sea ice for nearly all of their lifecycle functions. Rising global temperatures are causing this sea ice to disappear. With less sea ice, polar bears are forced to stay longer on […]

Earth Wise ·

2024/03/06

For the first time in a while, the monthly report on the US climate did not feature record-setting heat. The average January temperature across the contiguous U.S. was 1.6 degrees above the average, but that only ranked it in the middle third of the climate record. The diminishing El Niño probably helped. On the other […]

Earth Wise ·

Groundwater is found underground in aquifers and it bubbles up naturally into springs, streams, and rivers. It’s also often pumped out for use by people. Researchers from UC Santa Barbara have conducted the largest assessment of groundwater levels across the globe, spanning 170,000 wells and nearly 1,700 aquifers across more than 40 countries. The team […]

Fusion energy

Earth Wise ·

2024/02/29

Nuclear fusion is the process that powers the sun. Two atoms of hydrogen unite to form one helium atom and release energy in the process. Hydrogen bombs work in this way and since their development in the 1950s, scientists have sought a way to use fusion to generate electricity. Many scientists believe that the key […]
