Not just heat: Climate change signs can be seen all around
You don’t just feel the heat of global warming, you can see it in action all around.
Some examples of where climate change’s effects have been measured:
—Glaciers across the globe are melting and retreating, with 279 billion tons of ice lost since 2002, according to NASA’s GRACE satellite. Jakobshavn Glacier in Greenland is flowing faster than any other glacier on Earth. In 2012, it hit a record pace of about 75 inches per hour (1.9 meters). In 2017, it slowed down to 40 inches per hour (1 meter). The Portage Glacier in Alaska has retreated so much it cannot be seen from the visitor center that opened in 1986.
