First of all, this tornado was not the biggest and strongest tornado ever recorded on Earth, as one Oklahoma City weather-caster said. We don’t know the wind speeds yet, and until then it cannot be given an EF […]

You can see the multiple suction vortices in the tornado. I think this video may have some very high scientific value.

Devastation in Moore (Suburb of OKC). This tornado was 14 years to the month after the May 3, 1999 EF 5. It passed very nearly over the same area.

Correction: Hat tip to Daniel Linek who spotted my mistake. This is a CIRCUMSCRIBED Halo. Not a Circumzenithal Arc . See here: http://www.atoptics.co.uk/halo/circum.htm

John Cook over at Skeptical Science has produced an excellent video, that explains why anyone who telling you the climate has stopped warming, or that the planet is now cooling is wrong. 

Utterly wrong. […]

Vincent Van Gogh painted his most turbulent images when insane. The Labrador Current resembles Van Gogh’s paintings when it becomes unstable. There is no […]

Every summer, thousands of people drive out to Chincoteague in Virginia to see the beautiful beach, wild ponies, and the stunning National Wildlife Refuge. To get there, they drive around the long NASA runway at […]

A bit late on spotting this bit in case you have not seen it:

Anecdotal evidence can be very interesting, and it can lead to great discoveries, but it’s usually false. Unfortunately, many people make almost all of their decisions based on it. In some rare cases it’s almost a […]

We are very near passing a milestone. The CO2 levels will likely soon reach 400 ppm at the Mauna Loa Observatory in Hawaii. The curve of course is named after Charles Keeling who started the measurements in […]

Each dot is a Molecule of Carbon Monoxide ( A stack of two molecules actually). The world’s smallest animation ever made. More here.

Note I previously wrote atom instead of molecules and that has been […]
