When we were in early 2015, scientists announced that 2014 had been the hottest year on record. Now that we are in 2016, climate scientists are announcing that 2015 was even warmer.
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 year since 1880, continuing a long-term trend of rising global temperatures. “
” With the exception of 1998, the 10 warmest years in the 134-year record have all occurred since 2000, with 2010 and 2005 ranking as the warmest years on record “
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 working to reverse this “crime”, Environment Minister Izabella Teixeira said.”
This takes place as on a global scale, the world has lost a staggering 900,000 square miles (2.3 million square kilometers) of forests between 2000 and 2102 to deforestation or fire.
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
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 … Read more
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 … Read more
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 Watts per square meter imbalance implies that carbon dioxide levels need to be reduced to about 350 ppm to restore the energy budget to equilibrium.”
“The most recent measurements show that carbon dioxide levels are currently 392 parts per million and scientists expect that concentration to continue to rise in the future.”
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 “ Nice video assembly of Apollo 8 astronaut audio & photos leading to iconic “EARTHRISE” image “ I just had to click.
To say the least, I wasn’t disappointed as this making of clearly explains how such a beautiful image was created by the Apollo 8 crew.
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 14 were chosen as they have a direct and immediate impact on people’s lives. None of these methods are concerning carbon dioxide, which also have to be tackled in the meantime.
One of the main ways is switching to cleaner burning cookstoves. I have previously tackled this topic here and explained how this could save two million people per year.
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 is our Sun compared to other stars? In a dramatic and popular video featured on YouTube, the relative sizes of planets and stars are shown from smallest to largest. “
The video is visible in the full post below. This clearly demonstrates how infinitesimal we are and how our beautiful planet is tiny, thus the need to protect our ability to live on it…
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 … Read more
With some late – again – I would like to propose you my selection of the best pictures of the NASA’s Astronomy Picture of the Day (APOD). As always, here is my selection of the best pictures of last month. Today’s picture :
Sometimes it looks like the Sun is being viewed through a large lens. In this case, however, there are actually millions of lenses: ice crystals. As water freezes in the upper atmosphere, small, flat, six-sided, ice crystals might be formed.
I am absolutely still amazed at how many splendors can be seen at night (and day). I just hope we may find a way to make our nights darker so more people can see them.
