Oh, The Things You Can See From On High

Sand and soot in NW China. A huge sandstorm caused school sto close in China. The view from Aqua shows it well. The brown cloud of soot is now almost a constant over China. One reason why they are feverishly working to get away from "clean" coal. It's choking them to death!

I spent a little while looking at today’s images from NASA’s Terra and Aqua satellites with their amazing MODIS imager that sends back true colour images from an altitude of around 700 km. Here are a few things I spotted in just a short period of browsing this evening. Click any image for a much larger view. Here is a view of just some Sahara sand blowing north into Greece …

More About The Guy Who Almost Poisoned The Planet (As Seen on COSMOS Sunday Night)

More About The Guy Who Almost Poisoned The Planet (As Seen on COSMOS Sunday Night)

If you saw COSMOS Sunday night, (20 April) then you might be fascinated by the story of Thomas Midgley who invented lead additives for gasoline, and formed the Ethyl Corporation. Neil deGrasse Tyson used the entire episode to tell the story Clair Patterson who discovered the age of the Earth. In doing so, he also discovered that the lead additives in the gasoline were burning slowly poisoning all plant and …

Great Lakes Ice Unprecedented? Hardly.

Great Lakes Ice Unprecedented?  Hardly.

The headline above is on the Huffington Posts front page this evening, and it’s rather misleading. Yes, it’s been a rather cold winter around the Great Lakes and a cold spring has slowed the ice melt as well. It’s really not that big of a deal however, and the claim that this will affect the environment for years is more than dubious. The ice was worse in the cold winters …

Can’t Get Enough of Cosmos? Netflix Has 6 Hours of Neil deGrasse Tyson

Can't get enough of COSMOS? Netflix has more from Dr. Neil de Grasse Tyson.

I have mentioned the lectures you can buy from the Teaching Company before here, and one of those lecture sets is a six lecture series called The Inexplicable Universe, by Neil deGrasse Tyson. It’s worth the money IMHO, but before you buy it, Netflix has made available this entire series for its customers. That’s a pretty good deal. Now, this series does not have all the flash bang the COSMOS …

New Research Shows Asian Soot Cloud Affecting Pacific Storms

Air pollution from Asia streaming into the Pacific. Image taken today from NASA Aqua Satellite.

A group of researchers from Texas A & M University have a paper in the Proceedings of the National Academy of Sciences (PNAS) this week that is getting a lot of attention. Cloud droplets and rain drops need something to form on, and without dust and other aerosols in the atmosphere we would see a lot less of both. Sometimes though, the addition of particulates can cause tiny cloud droplets …

The Most Pervasive Scientific Myth

The Most Pervasive Scientific Myth

I’ve written before here about how pervasive the myth is that science is divided about the reality of and the threat of man-made interference with our climate system. It truly is the number one science myth out there. Just by writing this post, I’ll get the usual comments with links to the usual rabid political sites (with unflattering pictures of Al Gore) telling me that thousands of scientists disagree, and …

Wave Clouds, Contrails, and Sahara Dust

They dod not last long but for a few minutes were pretty nice.

What causes this? Very good website about it here: It was a bit chilly with an onshore sea-breeze, but sparkling early spring sunshine in spite of it being 10° C. I got a decent pic of the Ocean City pier that was damaged by a February nor’easter. Also notice the Jet contrails over the Eastern Mediterranean today. This image from the NASA Terra satellite about 600km up. Dust blowing off …

The Melt Begins- Arctic Sea Ice Max Was 5th Lowest on Record

From NSIDC/NOAA

The March Sea Ice Record is downward at 2.6% /decade. The melt season is now extending by 5 days per decade. Most of the ice is very young ice so the melt will likely be rapid, depending on weather conditions.
