NOAA: Record Antarctic Sea Ice Growth Linked To Its Staggering Loss Of Land Ice

October 11, 2014 by Joseph Romm

Sea Ice and Land Ice

NOAA said that “as counterintuitive as expanding winter Antarctic sea ice may appear on a warming planet, it may actually be a manifestation of recent warming.” The thing to know about Antarctica and ice is that a large part of the South Pole’s great sheet of land ice is close to or at a point of no return.[read more]

Greenland And West Antarctic Ice Sheet Loss More Than Doubled In Last Five Years

August 28, 2014 by Joseph Romm

Growing Ice Loss

A new study finds that both the Greenland ice sheet and West Antarctic Ice Sheet (WAIS) have seen an astonishing increase in ice loss in just the past five years. This first-ever extensive mapping of the two great ice sheets using the CryoSat-2 satellite confirms the findings.[read more]

Jet Stream Changes Driving Extreme Weather Linked Again To Global Warming, Arctic Ice Loss

August 21, 2014 by Joseph Romm

Jet Stream and Climate Change

California is suffering through drought, while the East Coast sees flooding. Both are worsened by global warming. But in recent years you may have noticed a disproportionate increase in record-smashing extreme weather and suspected that’s also linked to global warming.[read more]

Biggest Loser: Thawing Greenland Competes With Collapsing Antarctic For Fastest Ice Loss

May 23, 2014 by Joseph Romm

Shrinking Ice and Environmental Risk

The worst-case scenario for sea level rise has now become simply the “business-as-usual” scenario, recent studies from NASA make clear. NASA glaciologist Eric Rignot says that the new papers “suggest that the globe’s ice sheets will contribute far more to sea level rise than current projections show.”[read more]

Greenland, Antarctica May Be Vulnerable To Rapid Ice Loss

August 3, 2013 by Joseph Romm

Sea Level Rise

Humanity faces 70 feet of sea level rise, possibly coming much sooner than has been expected if we continue with unrestricted carbon pollution. A study found stretches of ice on the coasts of Antarctica and Greenland are at risk of rapidly cracking apart and falling into the ocean.[read more]

Antarctic woes

January 14, 2010 by Lou Grinzo

The news from the bottom of the planet isn’t good, despite what one report would suggest… Major Antarctic glacier is ‘past its tipping point’: A major Antarctic glacier has passed its tipping point, according to a new modelling study. After losing increasing amounts of ice over the past decades, it is poised to collapse in a...[read more]

How fast is Greenland melting?

September 2, 2009 by Lou Grinzo

It is undeniable that accurate measurements are key to climate science, and therefore critical to public policy that’s informed by science. One of the problems humanity has to deal with is that some of the things we’d love to measure in great detail are conspicuously resistant to our efforts. A prime example is determining the yearly net...[read more]

900 billion metric tons

July 24, 2009 by Lou Grinzo

The title of this post is one of the scariest numbers I’ve run across in my energy and environmental research is a long time. Nine hundred billion metric tons. What is it? That’s the trend of net ice loss from the Arctic every year over the last few years. That’s 900 cubic kilometers of ice. Every year. (Drive down a straight, flat...[read more]
