Climate models may underestimate future warming on tropical mountains

PROVIDENCE, R.I. [Brown University] — In few places are the effects of climate change more pronounced than on tropical peaks like Mount Kilimanjaro and Mount Kenya, where centuries-old glaciers have all but melted completely away. Now, new research suggests that future warming on these peaks could be even greater than climate models currently predict.

Researchers led by a Brown University geologist reconstructed temperatures over the past 25,000 years on Mount Kenya, Africa’s second-highest peak after Kilimanjaro. The work shows that as ...

Tim Radford – Vast carbon sink found in Congo basin

A carbon sink as large as 20 years’ worth of US fossil fuel emissions has been identified in peatland in central Africa’s forests.

LONDON, 15 January, 2017 – British scientists have just discovered one of the richest stores of carbon on Earth. They have found 145,000 square kilometres of peatland – an area larger than England – in the forests of the central Congo basin.

The reservoir of compressed plant material holds at least 30 billion metric ...

Nadia Prupis – Surprise: Climate Change is Likeliest Cause for Extreme Arctic Heat

This year’s remarkably warm Arctic winter would have been “extremely unlikely” without climate change, according to a new analysis from a consortium of scientists dedicated to understanding the impacts of global warming.

World Weather Attribution (WWA) released its report after the Arctic was hit with record-breaking temperatures amid the hottest year in recorded history.

The North Pole’s temperature anomalies “were not seen in our natural world ensemble,” the group wrote. “In contrast, events like 2016 or ...

Charles Mudede – California Tells Trump It Will Launch Its Own Damn Satellite to Monitor Climate Change

The president of urban America, California Gov. Jerry Brown, gave a speech at the recent American Geophysical Union conference that not only declared war on the backward climate policies of the president of rural America, Donald Trump, but made it very clear that his state has the economic will and power ($2.5 trillion GDP) to pursue its own programs and policies. The things is this: Trump wants to shutdown NASA’s 58-year earth-monitoring project, which includes a set of satellites that ...

Andrea Germanos – NOAA Issues ‘Jaw-Dropping’ Assessment on ‘Unprecedented’ Arctic Warming

If President-elect Donald Trump’s appointments of a “band of climate conspiracy theorists” weren’t already stoking fears for the ever-warming planet, the latest Arctic Report Cardfrom the National Oceanic and Atmospheric Administration (NOAA) may well provide the ignition.

The annual assessment, released Wednesday, finds that “persistent warming” is driving “extensive changes” to the region. In fact, the average air temperatures were “unprecendented”—the highest on observational record—and “Arctic temperatures continue to increase at double the rate of the global ...

Lauren McCauley – Scientists Racing to Archive Climate Data Before Denier-in-Chief Trump Takes Office

Anticipating the worst under the incoming administration, a group of scientists are frantically trying to archive government climate data before President-elect Donald Trump’s “band of climate conspiracy theorists…storm the castle,” as one put it.

On Saturday, Slate meterologist Eric Holthaus posed the question: “Scientists: Do you have a US.gov climate database that you don’t want to see disappear? Add it here,” he wrote. “Please share.”

The response was “overwhelming,” Holthaus said Sunday, “We still need more input, more database ...

The world’s wet regions are getting wetter, the dry regions are getting drier

Research from the University of Southampton has provided robust evidence that wet regions of Earth are getting wetter and dry regions are getting drier but it is happening at a slower rate than previously thought.

The study, published in Scientific Reports, analysed the saltiness of the world’s oceans.

More rain and outflow from rivers in a region of an ocean means sea water gets diluted and therefore becomes less salty. More evaporation in another region takes away fresh water ...

Stephen Hawking – This is the most dangerous time for our planet

As a theoretical physicist based in Cambridge, I have lived my life in an extraordinarily privileged bubble. Cambridge is an unusual town, centred around one of the world’s great universities. Within that town, the scientific community that I became part of in my 20s is even more rarefied.

And within that scientific community, the small group of international theoretical physicists with whom I have spent my working life might sometimes be tempted to regard themselves as the pinnacle. In addition ...

Dr. Mercola – How Sunlight Affects Your Mental Health

Sunlight has a profound impact on your mental health — more so than any other weather phenomenon. That’s the conclusion of a recent study looking at links between weather and depression.1

Mental health data from more than 16,000 Brigham Young University students was used. Assessments had been filled out several times by each person over the course of six years. Each assessment was then matched to local weather data.

Nineteen different environmental factors, including solar irradiance (the amount of sunlight ...

Chris Mooney and Jason Samenow – The North Pole is an insane 36 degrees warmer than normal as winter descends

This story has been updated.

Political people in the United States are watching the chaos in Washington in the moment. But some people in the science community are watching the chaos somewhere else — the Arctic.

It’s polar night there now — the sun isn’t rising in much of the Arctic. That’s when the Arctic is supposed to get super-cold, when the sea ice that covers the vast Arctic Ocean is supposed to grow and thicken.

But in fall of 2016 — ...
