2013 was one of the warmest years since 1880

Both NASA and NOAA – US National Oceanic and Atmospheric Administration – have issued a joint presentation on how climate change made 2013 one of the warmest year ever recorded. It is worth showing to any climate change deniers you may know. According to NASA : ” NASA scientists say 2013 tied with 2009 and 2006 for the seventh warmest… Continue reading 2013 was one of the warmest years since 1880

Brazilian deforestation increasing

Here are some bad news I read last week : deforestation in Brazil is increasing again. For the past years, it had been decreasing steadily, reaching its lowest levels in two decades. But over the last year, deforestation increased by 28 percent over the previous one. As the BBC noted : ” The government is… Continue reading Brazilian deforestation increasing

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

For algae biofuels, it’s all about patience

Will your car – or mine, or any vehicle – be powered one day by algae ? Despite this solution being a great one compared to more traditional biofuels, we will have to be (really) patient as GigaOM notes : ” In 2010, Pike Research predicted that by 2020, the algae biofuel industry would only… Continue reading For algae biofuels, it’s all about patience

Earth is losing 500 billion tons of ice a year

To the NASA : ” Using satellite measurements (…), the researchers measured ice loss in all of Earth’s land ice between 2003 and 2010, with particular emphasis on glaciers and ice caps outside of Greenland and Antarctica. ” ” The total global ice mass lost from Greenland, Antarctica and Earth’s glaciers and ice caps during… Continue reading Earth is losing 500 billion tons of ice a year

NASA study backs 350 ppm objective

A new study by the NASA is bringing more credence to the fact we need to go back to carbon dioxide concentration of 350 parts per million.  This will hopefully be a huge boost to the 350.org campaign. As Climate Progress reported : ” According to calculations conducted by Hansen and his colleagues, the 0.58… Continue reading NASA study backs 350 ppm objective

Earthrise, the making of

I love the picture Earthrise. Since I first discovered it back to 2007, it has become the central part of my communications; It is featured on my Twitter account, my About.me page, my business cards and on the header of this website. So when Andrew Revkin from the New York Times tweeted about the “… Continue reading Earthrise, the making of

14 simple ways to fight climate change

What if we could in the same time slow down climate change, increase health and boost agriculture ? Is this too good to be true ? No, as to a NASA scientist we could do just that by focusing on both methane and soot (black carbon). Out of the 400 ideas that were studied, these… Continue reading 14 simple ways to fight climate change

Great astrophotographies – February 2011

I think this is a record of some sort as I am only publishing today my selection of astrophotographies for February… Anyway, here is my selection of the best pictures of the NASA’s Astronomy Picture of the Day (APOD). This month is a bit special as my favorite is a video : ” How big… Continue reading Great astrophotographies – February 2011

Greenland and Antarctica are melting much faster than predicted

To CleanTechies : ” According to a new NASA-funded study, Greenland and Antarctic ice sheets are losing mass at a much faster rate than previous model forecasts have predicted. “ ” Results suggest that the ice sheets, found only in Antarctica and Greenland, are melting faster than mountain glaciers and ice caps and are poised… Continue reading Greenland and Antarctica are melting much faster than predicted
