Unprecedented ice melt in Greenland

by

This is bad news.  As NASA states : ” For several days this month, Greenland’s surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations.“ “Nearly the entire ice cover of Greenland, from its coastal edges to its two-mile-thick center, experienced some melting at its … Read more

CO2 concentration reaches 400 ppm

by

This is historical : carbon dioxide concentration has reached in several places over the arctic a concentration of 400 parts per million. This doesn’t seem to be much, but pre-industrial levels were of 280 ppm. As you might remember, the safe level is considered by the scientific community to be at 350 ppm. CO2 concentration … Read more

Bad climate news from the Amazon and the Arctic

by

I recently wrote about positive feedback mechanisms that would increase climate change as temperatures increase. It seems we are already seeing the very first tragic examples.

The first one comes from Peru, where climate change led to a warming Atlantic Ocean, which itself led to a drying Amazon rainforest, which in their turn led to massive wildfires.

To The Daily Climate this took place in a part of the Amazon rainforest which was previously thought as to wet to burn. But this is not the only horrifying prospect.

IPCC underplayed the impacts of climate change

by

This is what arises as the Arctic is melting much faster than the IPCC predicted in its report in 2007. ( I had blogged much about their findings during my first year of blogging here) As Climate Progress notes : ” Far from being “alarmist,” predictions from climate scientists in many cases are proving to … Read more

Arctic sea ice sets new record low in 2011

by

This is not surprising as I was blogging about it two months ago. To TreeHugger : ” After several months of reporting near-record or record monthly levels of Arctic sea ice melting, German researchers now report that a new yearly record low has been set.” ” The area covered by Arctic sea ice has declined … Read more

Temperatures are going up and up…

by

I believe it is getting harder and harder for deniers to keep pretending climate change is a hoax (or a conspiracy…). Here are three articles that got my attention last week : First, Arctic Sea ice melt on track to set new record low in 2011. The second was about the heat wave scorching the … Read more

At long last a normal winter in the Arctic

by

To the Daily Green ” there’s more ice in the Arctic than at any time in recent years.” To the US National Snow and Ice Data Center (NSIDC) specialists March was particularly cold in the Arctic. As they note on their website : ” Ice extent was above normal in the Bering Sea and Baltic Sea, but … Read more

Glaciers are melting faster and faster

by

The UNEP and the World Glacier Monitoring Service published a report showing how glaciers all around the world are melting faster and faster, thus threatening the water supplies of hundred of millions of people. The report then noted that “the average annual melting rate of glaciers doubled after the turn of the millennium.” This scary … Read more

Great astrophotographies – December 2009

by

This is time for me to present my selection of the best pictures of the NASA’s Astronomy Picture of the Day (APOD). As always, this month was packed with beautiful images. It was as always difficult to select just ten.

For the last post of the year (and of the decade) let’s have a look at what the NASA say about my favorite picture : ” Northern Lights, or aurora borealis, haunted skies over the island of Kvaløya, near Tromsø Norway on December 13. ”

I particularly like aurora borealis, a natural phenomenon that occurs generally during nights in the ionosphere of both poles regions.

Latest (bad) news from the arctic

by

This week no less than three news about the arctic hit my aggregator. First and foremost the WWF released a new report on how the melting of the pole could threaten no less than a quarter of the human population. The second one is about Mr. Ban Ki-moon – the UN secretary general – who … Read more

Latest news from the Arctic

by

It has been a while I haven’t written anything on the Arctic. According to Bloomberg: “A Manhattan-sized chunk of ice may break away from a glacier in northwestern Greenland and fall into the sea within about two months.” Furthermore, to Reuters a US governmental agency released hundreds of highly detailed pictures of the Arctic quickly … Read more

Both poles are melting faster and faster

by

Wilkins ice shelfAs bad news came from Antarctica I thought it would be interesting to check out how the poles are warming. I wrote in December that Antarctica keeps on melting and it seems this phenomenon is aggravating.

As the BBC noted “Scientists say the collapse could mean the Wilkins Ice Shelf is on the brink of breaking away, and provides further evidence of rapid change in the region.”

The Arctic also warms significantly as recent studies carried out during the International Polar Year have shown. Both regions are warming more than any other.
