Study: How climate change threatens mountaintops (and clean water)

Mountains are far more than rocks. About half of the world’s drinking water filters through their high-elevation forests, plants, and soils, among other natural benefits.

Now, a new first-of-its kind study, in the journal Nature, shows how these mountain ecosystems around the globe may be threatened by climate change.

Rising temperatures over the next decades appear likely to “decouple” key nutrient cycles in mountain soils and plants, an international team of sixteen scientists reports. This is expected to disrupt the function of ...

Nadia Prupis – Global Sea Ice Hits Lowest Levels ‘Probably in Millenia’

Global sea ice levels are at their lowest in recorded history, according to new statistics from the U.S. National Snow & Ice Data Center.

In the Arctic, the loss is due to climate change and extreme weather events that are likely influenced by global warming, while the changes in the Antarctic may be attributed to natural variability, the center said.

But as a result of the declines in both regions, the total loss of ice is likely at the lowest it’s ...

Alexandra Jacobo – New study confirms findings of faster global warming, despite what the GOP claims

A new study has confirmed what the National Oceanic and Atmospheric Administration originally found in 2015 – the oceans are warming at nearly twice the rate we originally thought.

After publishing their findings in 2015, the NOAA was immediately attacked by members of the GOP. GOP members of the House Science, Space, and Technology Committee, headed by Rep. Lamar Smith, opened an investigation into the conclusions. According to Smith, “NOAA has failed to fully explain the ...

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 ...

Andrea Germanos – Sorry, Santa: North Pole Temps Could Climb 50 Degrees Above Normal

Santa will likely be feeling toasty as he does his final checks on the naughty-or-nice list because temperatures at the North Pole on Thursday are forecast to be as much as 50°F above normal.

Temperatures are expected to climb to near the freezing point of 32°F, computer models show.

Arctic ice melt ‘already affecting weather patterns where you live right now’

The dramatic melting of Arctic ice is already driving extreme weather that affects hundreds of millions of people across North America, Europe and Asia, leading climate scientists have told the Guardian.

Severe “snowmageddon” winters are now strongly linked to soaring polar temperatures, say researchers, with deadly summer heatwaves and torrential floods also probably linked. The scientists now fear the Arctic meltdown has kickstarted abrupt changes in the planet’s swirling atmosphere, bringing extreme ...

Reynard Loki – Trump Declares All-Out War on Environment With Fossil Fuel-Loving, Climate Change-Denying Cabinet Nominees

Scientists warn in a major new reportthat the increasingly rapid melting of Arctic ice could potentially be irreversible and have severe implications not just for Arctic ecosystems, but for the entire planet.

“The warning signals are getting louder,” said Marcus Carson of the Stockholm Environment Institute and one of the lead authors of the report, adding that these developments “also make the potential for triggering [tipping points] and feedback loops much larger.”

Researchers monitoring Arctic weather stations ...

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 ...

Alex Kirby – Arctic Tipping Points Put Earth at Risk

LONDON—If the world fails to slow the pace of climate change very soon by cutting emissions of the greenhouse gases that are heating the planet, Arctic tipping points threaten to overwhelm the region, new research reveals.

Not only that—the authors of the Arctic Resilience Report say the changes that are liable to affect the high northern latitudes could also trigger drastic changes worldwide.

The report, written by an international research team, is a project of the Continue Reading →

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 — ...
