Forget the Polar Vortex: January Wasn't That Cold

So much for the "polar vortex." Even with the cold air outbreaks in the Midwest and East during January, the month wound up being just 0.1 degree Fahrenheit below the 20th century average in the lower 48 states, the National Oceanic and Atmospheric Administration (NOAA) said on Thursday in its January climate report. Unusually mild and dry conditions in the West helped balance out the cold in the East, NOAA said.

Notably, although January was the coldest such month since 2011, not a single state had its coldest January on record.

The month featured a split screen nation, with almost everywhere east of the Rockies experiencing colder-than-average conditions, and areas west of the Rockies experiencing unusually warm conditions. For example, while Michigan and Georgia had a top 10 coldest January, Arizona, California, and Nevada had a top 10 warmest January. Read more...

Al Gore on Climate Change: 'Extreme Weather Events Are a Gamechanger'

Climate change made an appearance at the 44th annual World Economic Forum in Davos, Switzerland, thanks to former Vice-President Al Gore and former Microsoft CEO Bill Gates. The two world figures commented on how extreme weather events are intensifying global awareness of the climate change phenomenon

The weather events they mentioned include the likes of the recent typhoon Haiyan and Hurricane Sandy, both of which caused huge economic and human damage

“I think that these extreme weather events which are now a hundred times more common than 30 years ago are really waking people's awareness all over the world [on climate change], and I think that is a gamechanger, “ said Gore, as reported by The Guardian Read more...

Temperatures in 2013 Among the Hottest in 133 Years

Global surface temperatures in 2013 were among the highest since scientists started keeping records in 1880. But federal agencies on Tuesday differed when putting last year's climate in historical context.

The National Oceanic and Atmospheric Administration (NOAA) reports that 2013 tied with 2003 for the fourth warmest year. However, NASA said 2009 and 2006 tied for the seventh place

"This is a real thing," Gavin Schmidt, a climate scientists for NASA's Goddard Institute for Space Studies, told Mashable. "It doesn't go away because it's snowing in New York today." Read more...

Norwegian Wind Storm Makes it Impossible to Cross Streets

Storm Ivar is passing through Northern Europe, and it looks like it wants to take Norway with it, one frustrated Christmas shopper at a time.

Euronews published a video of people in Aalesund, Norway attempting to cross a street and failing miserably. The winds increasingly worsen, so much that local police carried some across the road to safety. While everyone in this clip eventually gets where they're going, Euronews reports that one man was blown into an intersection in an accident that required an ambulance.

The strong winds are just the latest in weird weather we've had this winter, which also includes the rare snowstorm in the Middle East. Read more...

Newly Discovered Greenhouse Gas More Harmful Than Carbon Dioxide

Researchers at the University of Toronto have discovered a new greenhouse gas that has the highest impact on global warming to date.

Called perfluorotributylamine, the man-made compound has been an unregulated staple in the electrical industry since the mid-20th century. Researchers found it to be the most "radiatively-efficient chemical" to date, which means it is highly efficient in damaging the atmosphere. As these chemicals clog the environment and break down its various layers, they open the doors to global warming, according to a release.

Strange Greenhouse Gas Warmed Ancient Mars

At first glance, Mars' 500-mile-long Nanedi Valles looks like the Grand Canyon, with its steep-sided walls and plunging crevasses, two features that indicate a history of water

However, the Mars we know today is one of freezing temperatures, arid conditions and, most importantly, a paper-thin atmosphere — all combined to create a hostile environment seemingly defiant of any life at all, let alone water

Scientists have floated the idea that meteorites assaulted the Red Planet billions of years ago, generating steam atmosphere to create the landscapes like the Nanedi Valles, a large valley that stretches 1.5 miles wide in some areas. However, it's more likely that an unusual greenhouse gas raised the planet's temperature to allow for flowing water. Read more...

'Visionary' Climate Scientist Mario Molina Earns Presidential Medal of Freedom

President Barack Obama awarded Mario Molina the Presidential Medal of Freedom at a White House ceremony Wednesday.

Alongside 15 others, the chemist earned what Obama called "the nation's top civilian honor" for his work uncovering how chemical pollutants called chlorofluorocarbons deplete Earth's ozone layer.

"Today, inspired by his example, we're working to leave our planet safer and cleaner for future generations," Obama said of Molina.

The well-decorated Molina also earned the 1995 Nobel Prize in Chemistry. He currently works at the University of California at San Diego and serves on the President’s Council of Advisors on Science and Technology. Read more...

Severe Thunderstorms Could Increase 40% by 2070

If you follow climate science at all, you’ve probably heard that a warming world is likely to generate more nasty weather and a lot more weather extremes, kind of like the extreme droughts and then torrential flooding that Colorado, New Mexico and other western states have experienced. Well that also goes for severe thunderstorms and tornadoes, according to a new study by researchers who used a new computer simulation to test the conditions which generate tornadoes.

Their results suggests that we and our progeny are in for some pretty terrible twisters in coming decades — a lot like those that ripped up the U.S. in 2012. Specifically, by the year 2070 severe thunderstorms in the eastern United States could rise by 40%, the researchers say. Ouch. Read more...

8 New Cities Submerged as Oceans Rise in Climate Change GIFs

How will the rising seas caused by climate change swallow up your city?

Nickolay Lamm, a 24-year-old researcher and artist has worked on answering this question for months now. In April, he created illustrations of how the increased sea level will impact cities in the U.S. like Miami, New York and Washington, D.CMashable turned them into GIFs that showed how much our world could potentially change if the earth's ice caps melt.

Now, Lamm has created eight new sets of illustrations, depicting how San Diego, San Francisco, and Charleston will look under five, 12, and 25 feet of seawater Read more...

Twitter Bot Auto-Debates Climate Change Critics

As anyone interested in the recent midterm elections can attest, arguing with people who’ll never agree with you is an exhausting hobby.

At least one developer has found a way to answer his would-be debaters without having to engage in a tiring, dead-end debate himself.

When it comes to climate change, many folks find themselves at odds with certain facts.

The developer in question (that would be Australian systems architect and entrepreneur Nigel Leck) got tired of arguing on Twitter with people who believe climate change is not occurring, so he built a bot that scrapes Twitter for certain strings of words then responds to the author of the offending tweet with a pre-packaged link containing a science-based counter-argument.

The dialog (or should we say rhetoric?) between climate change skeptics and those in the science crowd is apparently so formulaic that Leck’s bot can carry on an exchange with a real human for dozens of tweets. He hopes to make the auto-debate even more realistic and accurate in the future by parsing data from other climate change debaters on Twitter.

One thing the bot can’t do, however, is detect irony. If, for example, I sarcastically tweeted something like, “With weather like this, there’s no way global warming can be real,” the bot would respond as if I truly thought climate change was an unlikely theory. However, the bot does whitelist people when they respond that they don’t disagree with the bot’s science-based point of view.

Named “Turing Test” (after computer scientist Alan Turing’s famous criteria for machine intelligence), the bot can be found on Twitter at @AI_AGW.

If you could build a bot to conduct debates on your behalf — be those arguments religious, social, political, culinary, what have you — what issue would you choose as the most tiresome subject worthy of auto-debate?
