In this handout released by Governor of Yamalo-Nenets region Press Office, people dig in silt searching for mammoth bone fragments in the Pechevalavato Lake in the Yamalo-Nenets region, Russia, Wednesday, July 22, 2020. Fragments of a mammoth skeleton have been found by local reindeer herders in the lake a few days ago, and scientists hope to retrieve the entire skeleton - a rare find that could help deepen the knowledge about mammoths that have died out around 10,000 years ago.

This 2014 microscope photo provided by Dr. F. Dahlke shows 1.5 mm diameter eggs of Atlantic cod (Gadus morhua). Global warming looks like it will be a far bigger problem for the world’s fish species than scientists first thought, since a study led by Dahlke released on Thursday, July 2, 2020 shows that when fish are spawning or are embryos they are far more vulnerable to hotter water.

This March 31, 2018 photo provided by researcher A. Park Williams shows the Catalina Mountains in southern Arizona. 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, and about half of this historic drought can be blamed on man-made global warming, according to a study released Thursday, April 16, 2020 in the journal Science.

Suddenly expertise matters. In the time of coronavirus, America turns its worried eyes to Dr. Fauci and other experts. That's a big shift after decades of the public and its leaders downplaying the advice from scientists and other experts on everything from climate change to disaster planning.  (AP Photo/Andrew Harnik, File)

An Australian mining company says its pursuit of a huge lithium deposit in Nevada is critical to accelerating the manufacture of electric vehicles and reducing greenhouse gases. Opponents argue the mine can't be built without causing the extinction of the only native population of the rare desert wildflower known to exist in the world.
