Since the first Earth Day, the planet’s CO2 levels have gone off the rails

When Americans celebrated the first Earth Day on April 22, 1970, the planet’s atmosphere was markedly different than it is today. Now, almost five decades later, that number has shot up to around 412 ppm, nearly 90 ppm higher. It’s a change atmospheric researchers, geologists, and climate scientists call unparalleled in at least 800,000 years, though it’s likely carbon dioxide levels haven’t been this high in millions years.

Melting glaciers causing sea levels to rise at ever greater rates

Melting ice sheets in Greenland and the Antarctic as well as ice melt from glaciers all over the world are causing sea levels to rise. Glaciers alone lost more than 9,000 billion tons of ice since 1961, raising water levels by 27 millimeters, an international research team has now found.

80 Percent of New Arctic Sea Ice Melts Before Leaving Russian Coast

The northern coast of Russia is largely considered the most important spot for the formation of new sea ice in the Arctic Ocean. But scientists have discovered that 80 percent of this new sea ice now melts before it can leave coastal waters, up from 50 percent in 2000.

A marine heat wave in Western Australia that had lasting impacts on dolphin populations may be a disturbing sign of things to come, according to a new study. The researchers have determined that climate change will have more devastating consequences for marine mammals than what was previously realized.

Even Antarctica’s Coldest Region Is Starting to Melt

East Antarctica is the coldest spot on earth, long thought to be untouched by warming. But now the glaciers and ice shelves in this frigid region are showing signs of melting, a development that portends dramatic rises in sea levels this century and beyond.
