Some research suggests that, along with melting ice sheets and glaciers, the water pumped from underground for irrigation and other uses, on the rise worldwide, could contribute substantially to rising sea levels over the next 50 years. A new study published in Nature Climate Change says the magnitude is substantially lower.
A study out yesterday says that the lives of up to 13 million people in the United States may be disrupted by sea-level rise in the next century. But another study says that while much hard infrastructure like houses, piers, seawalls and roads may have to be kissed goodbye, some 70 percent of natural landforms along the Northeast Coast may be able to adjust themselves, and not suffer inundation.
Forests in the south-central United States are some of the country’s most productive and diverse. They also sit in a warming “hole”—an area where the progressive rise in temperature affecting most of the continent hasn’t yet taken hold. A team from Columbia University’s Lamont-Doherty Earth Observatory is studying how these forests might shift—or even disappear—when climate change does catch up with them, as expected.
A new study that looked at the feasibility of lowering sea levels by pumping water onto icy Antarctica offers a warning about the costs today’s greenhouse gas emissions may be creating for future generations.
Sometime soon, a flock of “Climate Birds” could be ascending from a former NATO base in northeast France to take the measure of climate change around the world.
Vast portions of the oceans contain low levels of the nutrients that normally sustain life. Yet these areas are not devoid of life. Once thought to be biological deserts, recent research has shown that such nutrient-poor marine systems could significantly contribute to the amount of carbon dioxide that is trapped into the deep ocean, influencing Earth’s climate.
The global trend toward hotter summers could make parts of the Middle East and tropics “practically uninhabitable” by the end of the century, new research published this week contends.
Globally, the tool estimates at least 11 inches of sea level rise this century with ambitious efforts to lower greenhouse gas emissions and as much as 52 inches if greenhouse gas emissions continue to grow unchecked.
Nicolás Young studies glaciers and ice sheets, and how they’ve changed in the past. His work earned him the Blavatnik Award for Young Scientists last fall, which came with a $30,000 prize. You can hear him talk about his research in this new video, produced by the Blavatnik Family Foundation.
That change would have affected the monsoons, today relied on to feed over half the world’s population, and could have helped tip the climate system over the threshold for deglaciation.
