Greenland ice is melting fast, and could potentially cause many meters of sea level rise

April 14, 2017 — As humans put more heat-trapping gases into the atmosphere, like carbon dioxide, ice around the planet melts. This melting can be a problem, particularly if the melting ice starts its life Continue reading New study shows worrisome signs for Greenland ice

Northern hemisphere sees in early spring due to global warming

Spring is sprung 26 days earlier than a decade ago, causing problems for the natural cycle of plants and wildlife, Climate News Network reports

March 1, 2017 — Spring is arriving ever earlier in the northern hemisphere. One sedge species in Greenland is springing to growth 26 days earlier than it did a decade ago. And in the US, spring arrived 22 days early this year in Washington DC. Continue reading Northern hemisphere sees in early spring due to global warming

OMG measurements of Greenland give us a glimpse of future sea rise

The Oceans Melting Greenland project is taking important measurements to determine how fast sea levels will rise

February 26, 2017 — If you meet a group of climate scientists, and ask them how much sea levels will rise by say the year 2100, you will get a wide range of answers. But, those with most expertise in sea Continue reading OMG measurements of Greenland give us a glimpse of future sea rise

Sea levels could rise by six to nine metres over time, new study warns

Evidence that continental ice sheets are sensitive to slight increases in ocean temperature suggests ocean levels will continue to rise for centuries

January 20, 2017 — Sea surface temperatures today are strikingly similar to those during the last interglacial period, when sea levels were six to nine metres above their present height, according to research. Continue reading Sea levels could rise by six to nine metres over time, new study warns

Sea level rise is accelerating, how much it costs is up to us

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.

Greenland’s ice melt accelerating as surface darkens, raising sea levels

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.

How Earth Changed In 2015

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 Threat Lurks in Greenland’s Melting Ice

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.
