At a UNESCO climate conference last week, scientists declared (once again) that climate change is already happening. The evidence is our wacky weather—even Paris, where the conference was held, was broiling in a historic heatwave. But the biggest red flag is the rise in peak global mean temperatures: Which means…
It sounds like a great idea: Grab a cleaving iceberg from the Greenland coast and live on it until it melts into the sea, getting a first-hand glimpse at the effects of climate change. But how exactly would one live on an iceberg? Inside this giant ball, of course.
A study published this week in the journal Nature concludes that sea-levels rose more slowly during the 20th century than previously believed. That being said, if the revision is corroborated, it will mean that the recent acceleration in sea level rise has been "significantly larger than previously supposed."
Scientists working in Greenland have discovered an extensive aquifer of meltwater that sits under the Greenland ice sheet all year round — but it's not known if this reservoir, which is about the size of Ireland, will ever make its way to the ocean.
