Important new research shows that sea levels are rising at unprecedented rates, and will have tremendous costs if we don’t slow them
March 14, 2016 — As humans emit heat-trapping gases into the atmosphere, it’s causing the Earth to warm. It’s also causing the ocean waters to rise. In fact, water rise is one of the clearest signatures of a warming world. The questions we want to answer are, how much will sea levels rise, and how fast?
Ice core records going back 800,000 years reveal a lot about carbon dioxide and temperature, but climate researchers want to go back further
March 9, 2016 — Somewhere deep below the ice in Antarctica lies a time capsule. It’s the holy grail of climate science and promises to reveal the past and future of Earth’s atmosphere. And right now, scientists are meeting in Hobart to work out a plan to dig it up.
Winnowing away of the ice, exacerbated by soot blown on to the ice from wildfires, means Greenland’s ice sheet is stuck in a ‘feedback loop’
March 3, 2016 — Greenland’s vast ice sheet is in the grip of a dramatic “feedback loop” where the surface has been getting darker and less reflective of the sun, helping accelerate the melting of ice and fuelling sea level rises, new research has found.
From raging forest fires to dwindling snowmelt to the extraordinary birth of new ocean islands
January 13, 2016 — Sometimes the best way to witness planetary happenings — and to gain perspective on them — is from high above. Below are satellite images and aerial photos from the NASA Earth Observatory that capture some of the more dramatic changes that shaped the earth over the past year.
A new discovery about the glacier shows that it can’t absorb meltwater the way it used to and is shedding 8,000 tons of ice a second.
January 10, 2016 — Greenland’s melting ice sheets are contributing more water to the oceans than previously realized, and that’s going to lead to even greater amounts of sea-level rise around the world, according to new research.
