Ice loss from Antarctica has sextupled since the 1970s, new research finds

Antarctic glaciers have been melting at an accelerating pace over the past four decades thanks to an influx of warm ocean water – a startling new finding that researchers say could mean sea levels are poised to rise more quickly than predicted in coming decades. The Antarctic lost 40 billion tons of melting ice to the ocean each year from 1979 to 1989. That figure...

Oceans Are Warming Faster Than Predicted

Up to 90 percent of the warming caused by human carbon emissions is absorbed by the world’s oceans, scientists estimate. And researchers increasingly agree that the oceans are warming faster than previously thought. Multiple studies in the past few years have found that previous estimates from the Intergovernmental Panel on Climate Change may be too low. A new review of...

Ten Grim Climate Scenarios If Global Temperatures Continue to Rise

The summer of 2018 was intense: deadly wildfires, persistent drought, killer floods and record-breaking heat. Although scientists exercise great care before linking individual weather events to climate change, the rise in global temperatures caused by human activities has been found to increase the severity, likelihood and duration of such conditions. Globally, 2018 is...

Vanishing Nutrients. It’s a hazard of climate change you probably haven’t heard of.

  Is it possible to starve yourself of nutrients while simultaneously gaining weight? It turns out the answer is yes. According to a growing body of research, rising carbon dioxide levels are making our food less nutritious, robbing key crops of vitamins essential to human development. Studies have shown that crops as varied as wheat, maize, soybeans and field...

19 of 20 World Leaders Just Pledged to Fight Climate Change. Trump Was the Lone Holdout.

It is telling that on two of the most contentious topics at the Buenos Aires Group of 20 meeting, the United States eventually joined 19 other world leaders on trade, but when it comes to climate change, President Donald Trump remained firmly alone in his belief that it is a hoax. Trump was the only holdout. While the communiqué affirms support for the Paris climate...

What climate change will do to America, region by region

Look, at this point, even the most stubborn among us know that climate change is coming for us. We really don’t have much time until the climate plagues we’re already getting previews of — mega-wildfires, rising sea-levels, superstorm after superstorm — start increasing in frequency. The 4th National Climate Assessment says all that and much more is on its way. Here’s...

Climate report details deep hits to the Southwest

Climate change is here. It’s human-caused. And it’s going to deliver a blow to American prosperity. Already hard-hit by drought, wildfires and declining water supplies, the southwestern United States will continue to face those challenges — and new ones. That’s the message from a federal report released over the holiday weekend about climate change and its impact on the...

Government climate report warns of worsening US disasters

As California’s catastrophic wildfires recede and people rebuild after two hurricanes, a massive new federal report warns that these types of extreme weather disasters are worsening in the United States. The White House report quietly issued the Friday after Thanksgiving also frequently contradicts President Donald Trump. The National Climate Assessment was written long...

Climate change: Warming gas concentrations at new record high

Concentrations of key gases in the atmosphere that are driving up global temperatures reached a new high in 2017. In their annual greenhouse gas bulletin, the World Meteorological Organization (WMO) says there is no sign of reversal in this rising trend. Carbon dioxide levels reached 405 parts per million (ppm) in 2017, a level not seen in 3-5 million years. Researchers...

Startling new research finds large buildup of heat in the oceans, suggesting a faster rate of global warming

The world’s oceans have been soaking up far more excess heat in recent decades than scientists realized, suggesting that Earth could be set to warm even faster than predicted in the years ahead, according to new research published Wednesday. Over the past quarter-century, the Earth’s oceans have retained 60 percent more heat each year than scientists previously had...

Huge reduction in meat-eating ‘essential’ to avoid climate breakdown

Huge reductions in meat-eating are essential to avoid dangerous climate change, according to the most comprehensive analysis yet of the food system’s impact on the environment. In western countries, beef consumption needs to fall by 90% and be replaced by five times more beans and lentils. The research also finds that enormous changes to farming are needed to avoid...

Huge risk if global warming passes 1.5C, warns landmark UN report

The world’s leading climate scientists have warned there is only a dozen years for global warming to be kept to a maximum of 1.5C, beyond which even half a degree will significantly worsen the risks of drought, floods, extreme heat and poverty for hundreds of millions of people. The authors of the landmark report by the UN Intergovernmental Panel on Climate Change (IPCC)...

The global climate refugee crisis has already begun

When Hurricane Florence struck the shores of North and South Carolina and Virginia, more than a million evacuees fled their homes seeking shelter from the storm. For some, there will be no return home, as their homes are damaged beyond repair or beyond what they can afford to repair. All these displaced people are not simply evacuees fleeing a dangerous hurricane. They...

Study: National Parks Bearing The Brunt Of Climate Change Impacts

Yellowstone National Park escaped the summer without any large conflagrations in its forests, but that could be an anomaly under the current pace of climate change.

5 hikes to find Colorado’s last glaciers before they’re gone for good

Time is running out to see Colorado’s year-round alpine glaciers before they recede into extinction — which is, in some cases, a couple decades off, according to a study from the Institute of Arctic and Alpine Research. In the Ice Age, glaciers carved much of Colorado’s alpine landscape. Wide mountain valleys — now dotted with towns and zig-zagged by hiking trails — are...

Shell and Exxon’s secret 1980s climate change warnings

In the 1980s, oil companies like Exxon and Shell carried out internal assessments of the carbon dioxide released by fossil fuels, and forecast the planetary consequences of these emissions. In 1982, for example, Exxon predicted that by about 2060, CO2 levels would reach around 560 parts per million – double the preindustrial level – and that this would push the planet’s...

Spring is Arriving Earlier, Messing With Bird Migrations

Thanks to climate change, spring now comes earlier. But how much sooner the season arrives varies across the U.S. That’s according to a new study that assessed the first appearance of leaves and flowers in nearly 500 U.S. National Wildlife Refuges over more than 100 years. Researchers found the irregular seasonal changes affect migratory birds’ breeding sites, an outcome...

Arctic’s strongest sea ice breaks up for first time on record

The oldest and thickest sea ice in the Arctic has started to break up, opening waters north of Greenland that are normally frozen, even in summer. This phenomenon – which has never been recorded before – has occurred twice this year due to warm winds and a climate-change driven heatwave in the northern hemisphere. One meteorologist described the loss of ice as “scary”....
