Current Emissions Put the World on Track for Biodiversity Collapse

The lemurs of Madagascar and Himalayan snow leopards are among the hundreds of endemic species that will all but disappear if greenhouse gas emissions go unchecked. 

The plants and animals that are unique to a single location such as one island or one country, are particularly vulnerable to climate change, according to research by a global team of scientists published in the Biological Conservation journal on Friday. They’re almost three times more likely to go extinct, according to an analysis of almost 300 biodiversity hotspots on land and sea. 

“Unfortunately, our study shows that those biodiversity rich-spots will not be able to act as a safe haven from climate change,” said Mariana Vale, a researcher at the Federal University of Rio de Janeiro and a co-author of the study. “This could greatly increase extinction rates worldwide.”

Earth’s carbon dioxide levels hit record high, despite coronavirus-related emissions drop

The coronavirus-related economic downturn may have set off a sudden plunge in global greenhouse gas emissions, but another crucial metric for determining the severity of global warming — the amount of greenhouse gases actually in the air — just hit a record high.

According to readings from the Scripps Institution of Oceanography and the National Oceanic and Atmospheric Administration (NOAA), the amount of CO2 in the air in May 2020 hit an average of slightly greater than 417 parts per million (ppm). This is the highest monthly average value ever recorded, and is up from 414.7 ppm in May of last year.
