It seems anywhere scientists look for plastic, they find it: from the ice in Antarctica, to the first bowel movement produced by newborn babies. Now, researchers are finding that the amount of microscopic plastics floating in bottled drinking water is far greater than initially believed.
A two-decade-long dry spell that has parched much of the western United States is turning into one of the deepest megadroughts in the region in more than 1,200 years, a new study found.
And about half of this historic drought can be blamed on man-made global warming, according to a study in Thursday’s journal Science.
Scientists looked at a nine-state area from Oregon and Wyoming down through California and New Mexico, plus a sliver of southwestern Montana and parts of northern Mexico. They used thousands of tree rings to compare a drought that started in 2000 and is still going — despite a wet 2019 — to four past megadroughts since the year 800.
Early this month, scientists announced a surprising discovery: The “fingerprint” of climate change is now detectable in everyday weather. In fact, evidence of global warming can be found in the planet’s weather every day, minute, and second since 2012.
But wait —you, a person who actually paid attention in your high school atmospheric science class, say — weather and climate are not the same! Right you are, dear reader. Weather is what happens in the moment (rain passing through, or the current temperature outside). Climate is average weather over time.
