The loss of ‘everlasting ice’ threatens Mongolian reindeer herders’ way of living

The loss of ‘everlasting ice’ threatens Mongolian reindeer herders’ way of...

Patches of long-frozen snowpack and ice in the Mongolian steppes are rapidly vanishing — with dire consequences for the reindeer and herders who rely on the icy spots. About 30 families, members of the Tsaatan people (SN: 1/14/03), live within a remote part of northern Mongolia called the Ulaan Taiga Special Protected Area. Interviews with…
5 things to understand about battling environment modification by planting trees

5 things to understand about battling environment modification by planting trees

The idea seemed so catchy, simple and can-do. There’s room to plant enough trees, albeit many, many, many trees, to counter a big chunk of the planet-warming carbon spewed by human activities. A more realistic look at that feel-good estimate, however, might shrink it down to a useful idea, but no panacea. The proposed fabulous…
California’s methane super-emitters

California’s methane super-emitters

Methane is a much more potent greenhouse gas than carbon dioxide, trapping much more heat. Point-source methane emitters are typically small—usually less than 10 meters in diameter—but they emit plumes of highly concentrated methane. So if we want to reduce the amount of methane we’re spouting into the air (which we obviously should, although we’re not),…
California land fills are burping high levels of climate-warming methane

California land fills are burping high levels of climate-warming methane

Landfills, pipelines or dairy farms: The largest sources of methane released to the atmosphere can now be spotted from the sky. A team of researchers used airborne remote sensing to pinpoint the exact locations of some of California’s biggest belchers of methane, a potent greenhouse gas. Of those concentrated “superemitters,” landfills were the biggest sources…
The environment crisis is currently having extreme effects for human health

The environment crisis is currently having extreme effects for human health

A bushfire rages in Australia's Blue Mountains. Andrew Merry/Getty In a new, wide-ranging assessment focused on the human health impacts of climate change, a global collaboration of over 100 scientific experts paint a dire picture: The climate crisis is making us sick. If we fail to limit greenhouse gas emissions, we will be faced with…

Emissions generated between 2016 and 2030, when the agreement expires, will account for…
‘Local weather emergency’: Over 11,000 scientists sound thunderous warning

‘Local weather emergency’: Over 11,000 scientists sound thunderous warning

Scientists from 153 different countries have issued a dire warning. CNET Humanity faces "untold suffering" unless we significantly improve our efforts to protect the planet, an alliance of international scientists and researchers warn. That warning, published Tuesday in the journal BioScience, summarizes much of the scientific research over the last 40 years and states that the…
Local weather change: How one can make a distinction

Local weather change: How one can make a distinction

Protesters in New York in September. Erik McGregor A heatwave has turned Western Europe into a furnace. The Amazon is on fire. Glaciers in Iceland are melting. Earth just sweltered through its hottest five-year period on record. The seemingly never-ending newsreel of climate catastrophes can leave us feeling powerless. And while it's unfortunately true that…
In an environment crisis, is geoengineering worth the threats?

In an environment crisis, is geoengineering worth the threats?

Geoengineering ideas — tinkering with the climate to delay or halt the worst effects of global warming — have been around for decades. Few such ideas have progressed past the thought experiment stage, due in part to concerns that the cure could be worse than the disease. But as dire warnings about climate change’s impacts…

Malin Pinsky had the first of two lightbulb moments while standing on the bridge of a research ship crossing the churning Drake Passage, which separates the tip of South America and Antarctica. It was 2003, and Pinsky was five months out of his undergraduate studies in biology and environmental science. He was scanning the sky…
