Although the effects of global warming are gradual, here are some pictures of global warming captured by satellite, so you can really see some of the changes happening to the Earth right now.
This is a picture of the retreat of Jakobshavn Glacier in Greenland. This glacier drains out about 6.5% of the Greenland ice sheet into the ocean. It’s one of the fastest moving glaciers in the world, moving at a speed of 20 meters/day. It’s one of the glaciers that contributes the most to potential sea level rise.
This image shows the predicted temperature rise from global warming in 2070-2100 over temperatures from the 1960s to the 1990s.
This image shows the extent of arctic ice loss in 2007. It was the largest decrease on record, with the Northwest passage opening up for a long period of time.
This is an image of the Larsen B ice shelf in Antarctica, which has been crumbling over the last few years. Some of the largest icebergs ever seen have broken away from this shelf.
This is an image of the rise in global carbon dioxide levels matched with the rise in global temperatures.
We’ve written many articles about global warming for Universe Today. Here’s an article about how cosmic rays don’t increase global warming, and here’s an article about the effects of global warming.
We’ve also recorded an episode of Astronomy Cast about Earth. Listen here, Episode 51: Earth.
