Terrible and wonderful news on climate change

Last week saw quite appalling news on climate change, enough to make you weep, but it also saw an incredibly uplifting report, enough perhaps to create a real sense of optimism about climate change.

Let's get the bad news out of the way first.  Be warned; it is more frightening than any horror movie you have ever seen. The bad news related to data drawn from untapped satellite archives on glaciers distinct from the Greenland and Antarctic ice sheets. The findings were published in a report in Nature.  There is a scary finding and terrifying finding.
