Our Atmospheric CO2 is now past the point that in the Deep Past has Meant the Melting of the Antarctic Ice Sheets

Ann Arbor (Informed Comment) – So as a historian, I am particularly interested in what the past tells us about the present. I’ve taught courses on climate change in history. But of course my kind of history doesn’t go back very far from the point of view of physical scientists. The academic discipline of “history” […]

Desalinating Seawater sounds Easy, but there are cheaper and more sustainable Ways to meet people’s Water Needs

The Conversation

By Gregory Pierce, University of California, Los Angeles | – (The Conversation) – Coastal urban centers around the world are urgently looking for new, sustainable water sources as their local supplies become less reliable. In the U.S., the issue is especially pressing in California, which is coping with a record-setting, multidecadal drought. California Gov. Gavin […]

Scientists Conclude Climate Change Contributed to 1/3 of Pakistan being Under Water; Calls for Debt Relief

Juan Cole

Ann Arbor (Informed Comment) – The massive monsoon floods that affected 33 million people in Pakistan, destroyed 1.3 million homes, turned the southern province of Sindh temporarily into a new inland sea nearly 70 miles across, and killed off 80% of the country’s livestock was in part fueled by the human-caused climate emergency. So argues […]

Climate Emergency: Typhoon Merbok, fueled by unusually warm Pacific Ocean, pounded Alaska’s vulnerable coastal Communities at a critical Time

The Conversation

By Rick Thoman, University of Alaska Fairbanks | – The powerful remnants of Typhoon Merbok pounded Alaska’s western coast on Sept. 17, 2022, pushing homes off their foundations and tearing apart protective berms as water flooded communities. Storms aren’t unusual here, but Merbok built up over unusually warm water. Its waves reached 50 feet over […]

Nine out of 10 marine Species could disappear by 2100, Scientists warn

Daniel T. Cross

( Sustainability Times) – If the planet continues to warm at current rates, by the end of the century as many as 90% of marine species will be at risk of going extinct. This stark warning comes from a team of scientists who examined some 25,000 species, including fish, marine plants, bacteria and protozoans, which […]

What’s going on with the Greenland ice sheet? It’s losing ice faster than forecast and now irreversibly committed to at least 10 inches of sea level rise

The Conversation

By Alun Hubbard, University of Tromsø | – I’m standing at the edge of the Greenland ice sheet, mesmerized by a mind-blowing scene of natural destruction. A milewide section of glacier front has fractured and is collapsing into the ocean, calving an immense iceberg. Seracs, giant columns of ice the height of three-story houses, are […]

Climate Emergency: Marine Life Endangered as Mediterranean Heats Up

The Conversation

By John Spicer, University of Plymouth | – The ocean sustains all life on our planet. It provides food to eat and oxygen to breathe, while playing a key role in moderating our climate. But marine life is increasingly threatened by climate change. The ocean is becoming considerably warmer, affecting its ability to sustain life. […]

The World’s biggest Ice Sheet is more vulnerable to Global Warming than Scientists previously Thought

The Conversation

By Chris Stokes, Durham University and Guy Paxman, Durham University | – The eastern two thirds of Antarctica is covered by an ice sheet so large that if it melted the sea would rise by 52 metres [~yards]. Most scientists had once thought this ice sheet was largely invulnerable to climate change, but not any […]

Arctic is warming nearly four Times faster than the rest of the World – New Research

The Conversation

By Jonathan Bamber, University of Bristol | – The Earth is approximately 1.1℃ warmer than it was at the start of the industrial revolution. That warming has not been uniform, with some regions warming at a far greater pace. One such region is the Arctic. A new study shows that the Arctic has warmed nearly […]
