Sea levels are going to rise The amount of carbon dioxide in the Earth’s atmosphere directly and indirectly determines the sea level. The more CO2 the higher the sea level. The details matter, the mechanism is complex, and as CO2 levels change, it takes an unknown amount of time for the sea level to catch…

I’ve got a new post up at 10,000 Birds on a study looking at changing populations of several hundred common species of birds in Europe and North America (mainly the US). The two subcontinents exhibit dramatically different patterns, as shown in the enigmatic graph above. Go to the post to unravel this intriguing mystery!

Corals are ocean-dwelling invertebrates in the same phylum as jellyfish. Corals are tiny and create an exoskeleton that is fixed to something hard, like the remains of previously existing corals. So these organisms build up a geological stratum, a reef, beneath the surface of the sea, often close enough that parts of the reef are…

There is a new study out in Nature that is liable to be misinterpreted, or that may be flawed in a way that lends itself to misuse, in the context of climate science driven policy. The study is “Northern Hemisphere hydroclimate variability over the past twelve centuries” by Fredrik Charpentier Ljungqvist, Paul J. Krusic, Hanna…

An Nasty Surprise in the Greenhouse

Remember that movie, The Day After Tomorrow? Check out this (not too new but still very current) video by Greenman3610, with

Though not enough. And for the wrong reasons. But this is still good news. Somewhere around 1990, but you could justify an earlier date if you like, science knew enough about global warming, the increase in the planet’s surface temperatures caused by human release of greenhouse gas pollution and other human effects, to have initiated…
