With Donald J. Trump about to take control of the White House, it would seem a dark time for the renewable energy industry. After all, Mr. Trump has mocked the science of global warming as a Chinese hoax, threatened to kill a global deal on climate change and promised to restore the coal industry to its former glory.

So consider what happened in the middle of December, after investors had had a month to absorb the implications of Mr. Trump’s victory.

Mexico’s Climate Migrants are Already Coming to the United States

 . . . Mexico’s climate story reflects a growing global problem. Worsening droughts, floods, wildfires, and rising seas will drive millions from their homes, all around the world.

From Mexico to China, Bangladesh to Senegal, climate migrants everywhere will relocate to the nearest safe place, says sociologist Cristina Bradatan, also of Texas Tech. Sometimes that means crossing borders . . .

Atmospheric levels of methane, a powerful greenhouse gas, are spiking, scientists report

washingtonpost.com - Chris Mooney - December 11th 2016

The best news about climate change that we’ve heard lately is that for three years straight, the world’s energy-related emissions of carbon dioxide, the most important greenhouse gas, have been flat. The gas has continued to accumulate in the atmosphere, but emissions haven’t gone up, even as economies have continued to grow.

But now we learn that there’s a major dose of bad news to accompany that: What’s true for carbon dioxide is not at all true for methane, the second most important greenhouse gas. Atmospheric concentrations of this gas — which causes much sharper short-term warming, but whose effects fade far more quickly than carbon dioxide — are spiking, a team of scientists reports in an analysis published Sunday in the journal Environmental Research Letters.

El Niño and Global Warming Blamed for Zika Spread

Mosquito-borne diseases like Zika can be extremely sensitive to climatic changes

The combination of climate change and last year’s El Niño phenomenon likely created the perfect playground for the Zika virus to spread rapidly across South America, a new study finds.

Both the Zika virus and the mosquitoes that carry it have been present in different parts of the world for a while. But several factors, including specific climatic conditions, could have catapulted the disease to public health emergency status, according to researchers from the University of Liverpool.

President Obama Bans Oil Drilling in Large Areas of Atlantic and Arctic Oceans

washingtonpost.com - by Darryl Fears and Juliet Eilperin - December 20, 2016

President Obama moved to solidify his environmental legacy Tuesday by withdrawing hundreds of millions of acres of federally owned land in the Arctic and Atlantic Ocean from new offshore oil and gas drilling.

Obama used a little-known law called the Outer Continental Shelf Lands Act to protect large portions of the Chukchi and Beaufort seas in the Arctic and a string of canyons in the Atlantic stretching from Massachusetts to Virginia. In addition to a five-year moratorium already in place in the Atlantic, removing the canyons from drilling puts much of the eastern seaboard off limits to oil exploration even if companies develop plans to operate around them.

Arctic Heating Up at Twice as Fast as Rest of Globe

           

Arctic Sea Ice Disappearing

CLICK HERE - NOAA - Arctic Report Card: Update for 2016

cnn.com - by Mayra Cuevas and Max Blau - December 14, 2016

The Arctic is heating up twice as fast as the rest of the world -- triggering a "massive decline in sea ice and snow," according to a new federal report.

On Tuesday, the National Oceanic and Atmospheric Administration released its 11th annual Arctic Report Card, which compiles data from 61 scientists in 11 countries.

"Rarely have we seen the Arctic show a clearer, stronger or more pronounced signal of persistent warming and its cascading effects on the environment than this year," Jeremy Mathis, director of NOAA's Arctic Research Program, said in a statement.

Rift in Antarctica's Larsen C Ice Shelf

submitted by Albert Gomez

           

On Nov. 10, 2016, scientists on NASA's IceBridge mission photographed an oblique view of a massive rift in the Antarctic Peninsula's Larsen C ice shelf. Icebridge, an airborne survey of polar ice, completed an eighth consecutive Antarctic deployment on Nov. 18.

nasa.gov - December 1, 2016 - Editor: Sarah Loff

Ice shelves are the floating parts of ice streams and glaciers, and they buttress the grounded ice behind them; when ice shelves collapse, the ice behind accelerates toward the ocean, where it then adds to sea level rise. Larsen C neighbors a smaller ice shelf that disintegrated in 2002 after developing a rift similar to the one now growing in Larsen C.

The IceBridge scientists measured the Larsen C fracture to be about 70 miles long, more than 300 feet wide and about a third of a mile deep. The crack completely cuts through the ice shelf but it does not go all the way across it – once it does, it will produce an iceberg roughly the size of the state of Delaware.

Unless the world stops burning fossil fuels that are fuelling global warming, irreversible changes in the Arctic could have disastrous effects for the people that live there and for the rest of the planet, researchers warned on Friday.

The Arctic's ecosystems are fundamentally threatened by climate change and other human activities, such as oil and gas extraction, they said in a report for the Arctic Council, an inter-governmental forum working to protect the region's environment.

Climate Changing 'Too Fast' for Species

           

Tropical species are thought to be particularly vulnerable.  Thinkstock

CLICK HERE - STUDY - Rates of change in climatic niches in plant and animal populations are much slower than projected climate change

bbc.com - by Helen Briggs - November 23, 2016

Many species will not be able to adapt fast enough to survive climate change, say scientists.

A study of more than 50 plants and animals suggests their ability to adapt to changes in rainfall and temperature will be vastly outpaced by future climate change.

Amphibians, reptiles and plants are particularly vulnerable, according to US researchers.

And tropical species are at higher risk than those in temperate zones.

Oil demand won't peak before 2040, despite Paris deal: IEA

reuters.com - November 16th 2016 - Amanda Cooper

The International Energy Agency expects global oil consumption to peak no sooner than 2040, leaving its long-term forecasts for supply and demand unchanged despite the 2015 Paris Climate Change Agreement entering into force.

The Paris accord to cut harmful emissions seeks to wean the world economy off fossil fuels in the second half of the century in an effort to limit the rise in average world temperatures to "well below" 2 degrees Celsius (3.6 Fahrenheit) above pre-industrial times.

But while demand for oil to power passenger cars, for example, may drop, other sectors may offset this fall.
