The Siberian Express will ride again next week, as frigid air pushes across much of the U.S. with temperatures in some places dropping to as much as 50 degrees Fahrenheit below average for this time of year. 

The cold will come courtesy of two main weather features — a wobble in the upper level polar vortex that will pull cold air out of Siberia, Alaska and Canada, 

While this will be a headline-grabbing event, with temperatures remaining below zero Fahrenheit for the daytime high across the northern Rockies, parts of the Plains and Midwest, it is not likely to equal or beat the severity of the January 2014 Polar Vortex event.  Read more…

India may still be using fossil fuels for much of its power needs, but the country is quickly turning to renewable power sources. 

If you visited Kamuthi, in Tamil Nadu, one year ago, you would find delight and peace in its temples and greenery. But today, everyone is talking about its brand new power plant.

Kamuthi, located 90 kilometers outside Madurai, is now home to the world’s largest solar power plant at a single location. Spanning a 10-square-kilometer area, the plant has the capacity of 648MW, enough to power about 150,000 homes.  Read more…

The Weather Channel shuts down Breitbart: Yes, climate change is real

The Weather Channel has slammed Breitbart for using its reporting to argue that the earth is cooling, when in fact, it definitely is not.

Brietbart‘s use of an unrelated Weather Channel video to back up false claims that the earth is getting colder just didn’t sit well with the weather reporting service, which rarely if ever sticks its nose in anything political. It delivered a scathing and informative video message on Tuesday. 

The site didn’t stop there. It also ran a story entitled “Note to Breitbart: Earth Is Not Cooling, Climate Change Is Real and Please Stop Using Our Video to Mislead Americans,” alongside the video message. Read more…

Crack in Antarctic ice shelf threatens research station

A giant crack in East Antarctica is threatening to cleave off part of the ice where a key research station sits and leave the facility drifting on an iceberg.

The chasm, which was dormant for 35 years, is now growing at a pace of about 1.7 kilometers, or 1 mile, per year on the Brunt ice shelf, according to the British Antarctic Survey.

The U.K. science office on Tuesday said it was preparing to move the Halley VI Research Station to save it from splintering off into the sea. The station is a globally important platform for gathering data on space, weather, climate change and ozone measurements.  Read more…

Dakota Access pipeline opponents just scored a huge victory

Opponents of the Dakota Access Pipeline erupted in cheers on Sunday after U.S. regulators rejected a final permit needed to complete the controversial pipeline.

The U.S. Army Corps of Engineers said it won’t grant an easement that would’ve allowed the pipeline’s builders to run the conduit under Lake Oahe, a reservoir near the Standing Rock Sioux Reservation in North Dakota.

The decision is an enormous victory for the thousands of people camped near the disputed construction site. 

Native American activists and their allies have insisted that the $3.8 billion project would threaten the region’s water supplies and damage sacred sites. Critics also noted the 1,170-mile pipeline would boost U.S. greenhouse gas emissions by allowing for increased oil production in North Dakota’s shale region. Read more…

The National Park Foundation and Mashable joined forces on #GivingTuesday for a Facebook Live “View-A-Thon”to benefit America’s national parks and educate audiences about the impact of climate change on the National Park System.

Science wiz and Find Your Park Centennial Ambassador Bill Nye hosted the modern take on the telethon, conducting demonstrations and taking questions during the live event. Along with Joshua Laird, Commissioner of the National Parks of New York Harbor, Nye brought to life tangible examples of the dangers of climate change and its effect on our national parks – including cultural and historic sites. Throughout each segment of the “View-a-thon,” Nye urged viewers to make a difference by donating and do their part in protecting our parks. Read more…

Global warming blowout: Record highs beat record lows by 51-to-1 ratio in November

As the planet warms in response to the buildup of greenhouse gases in the atmosphere, the ratio of high temperature records compared to low temperature records has become more skewed. If the climate weren’t warming, that long-term ratio should average out to about 1-to-1. 

However, that isn’t the world we’re living in. A 2009 study found that the record highs to lows ratio was 2-to-1 for the lower 48 states during the 2000s, and this disparity has only grown since then. Projections show the imbalance increasing in coming decades as global warming continues.

Keeping in mind that individual months show considerable variability in weather patterns, it’s clear that over the long-term, the ratio of record highs to record lows is now strongly favoring record highs as well as record warm overnight temperatures. This is consistent with computer model projections of a warming world.  Read more…
