The NOAA-supported Northeast Regional Climate Center is currently reviewing temperature data for 2012 from throughout the 12-state region, and researchers have discovered that for most major sites–including Washington, DC, Boston, Philadelphia and New York City–it was the hottest year ever recorded–something we tend to overlook when we’re in the midst of storms and blizzards.

Climatologist Samantha Borisoff says, "The year 2012 was the warmest year on record for 23 of the 35 major climate sites in the Northeast.

We didn’t really know–until now. The ocean, which has risen an average of 8 inches since 1900, should rise another 3 feet or so by 2100, but without an accurate record of where we started, we can’t know if the melting starts to speed up or (hopefully) slow down.

On the Climate Central website, Michael D. Lemonick quotes researcher Ian Joughin as saying, "There are lots of processes in play and it remains unclear whether the ice loss will level out or slow down or speed up. We thought we understood ice sheets, but it’s clear we don’t. We need a lot more observations and a lot better modeling."

Permafrost is thawing all over the planet, and this releases the powerful greenhouse gas methane. Permafrost covers nearly a quarter of the northern hemisphere and may contain as much as 1,700 gigatons of carbon, which is twice the amount that is currently in the atmosphere. As it thaws, it could push global warming past one of the key "tipping points" that scientists believe could lead to runaway climate change.

I didn’t coin the word ‘superstorm’ but the Coming Global Superstorm, certainly brought it into the language. And the movie based on it, the Day After Tomorrow, fixed the idea of such storms in the public imagination.
