Unprecedented ice melt in Greenland

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… Continue reading Unprecedented ice melt in Greenland

CO2 concentration reaches 400 ppm

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… Continue reading CO2 concentration reaches 400 ppm

Bad climate news from the Amazon and the Arctic

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… Continue reading Bad climate news from the Amazon and the Arctic

IPCC underplayed the impacts of climate change

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… Continue reading IPCC underplayed the impacts of climate change

Arctic sea ice sets new record low in 2011

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… Continue reading Arctic sea ice sets new record low in 2011

Temperatures are going up and up…

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… Continue reading Temperatures are going up and up…

At long last a normal winter in the Arctic

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… Continue reading At long last a normal winter in the Arctic

Glaciers are melting faster and faster

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… Continue reading Glaciers are melting faster and faster

Great astrophotographies – December 2009

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… Continue reading Great astrophotographies – December 2009

Latest (bad) news from the arctic

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… Continue reading Latest (bad) news from the arctic

Latest news from the Arctic

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… Continue reading Latest news from the Arctic

Both poles are melting faster and faster

As 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… Continue reading Both poles are melting faster and faster
