Ice Melt

Ann Arbor (Informed Comment) – The Intergovernmental Panel on Climate Change has issued its sixth assessment report. The product of vast international cooperation, the report reflects the scientific community’s certitude that the globe’s climate is rapidly changing as a direct result of humanity burning coal, gasoline and natural gas, putting tens of billions of tons […]

Yellowstone is losing its snow as the climate warms, and that means widespread problems for water and wildlife – a new report details the changes

The Conversation

By Bryan Shuman | – When you picture Yellowstone National Park and its neighbor, Grand Teton, the snowcapped peaks and Old Faithful Geyser almost certainly come to mind. Climate change threatens all of these iconic scenes, and its impact reaches far beyond the parks’ borders. A new assessment of climate change in the two national […]

Climate explained: why is the frozen Arctic heating up faster than other parts of the world?

The Conversation

By Steve Turton | – What is Arctic amplification? Do we know what is causing this phenomenon? What effects is it having, both in the region and for the world? Is Antarctica experiencing the same thing? Human civilisation and agriculture first emerged about 12,000 years ago in the early Holocene. Our ancestors benefited from a […]

Climate Crisis

Antarctica is headed for a climate tipping point by 2060, with catastrophic melting if carbon emissions aren’t cut quickly

The Conversation

By Julie Brigham-Grette and Andrea Dutton | – While U.S. Secretary of State Antony Blinken draws attention to climate change in the Arctic at meetings with other national officials this week in Iceland, an even greater threat looms on the other side of the planet. New research shows it is Antarctica that may force a […]

Surging of Dangerous Greenhouse Gas Methane endangers our Planet: Why we Have to Stop It

The Conversation

By Drew Shindell | – Methane, the main ingredient in natural gas, is a larger climate problem than the world anticipates, and cutting its emissions will be crucial to slow global warming, a new United Nations report warns. The greenhouse gas is many times more powerful than carbon dioxide at warming the planet, and its […]

“Unimaginable Amounts of Water”: Human-Made Global Heating in Danger of “Uncorking” Massive Antarctic Glaciers, causing Sea Level Rise

Juan Cole

Ann Arbor (Informed Comment) – A new article in Geophysical Research Letters found that four times as much of the Antarctic ices shelves would melt under a scenario where we heat the earth by 7.2 degrees F. (4 degrees C.) as opposed to the current Paris Climate Treaty goals of 1.5 degrees C. or at […]

Climate Crisis

Antarctica’s ice shelves are trembling as Earth heats, threatening Sea Level Rise unless we Act Now

The Conversation

By Ella Gilbert | – Images of colossal chunks of ice plunging into the sea accompany almost every news story about climate change. It can often make the problem seem remote, as if the effects of rising global temperatures are playing out elsewhere. But the break-up of the world’s vast reservoirs of frozen water – […]

Acidification of Oceans

More CO2 in our Atmosphere now than any time since 3.6 mn Years Ago, when Oceans were 90 feet higher (that’s our fate)

Juan Cole

Ann Arbor (Informed Comment) – In a scientific shocker, the National Oceanic and Atmospheric Administration has found that despite the slowdown in carbon dioxide emissions in 2020 because of the pandemic, the concentration of CO2 in the atmosphere rose to a global average of 412.5 parts per million (ppm) from 410 in 2019. At the […]

Global heating from CO2 breaks Himalayan Glacier, floods sweep away Scores, destroy Hydroelectric Plant

Juan Cole

Ann Arbor (Informed Comment) – A huge chunk of the Nanda Devi glacier in the Himalayas broke off Sunday morning, melting and crashing down on villages around Joshimath in India’s Uttarakhand state, leaving nine dead and 140 unaccounted for. The turbulent grey deluge of water, ice and rocks slammed into two hydro-electric plants, destroying one […]
