The earth now has over 400 ppm CO2 which is more than its had in the last 20 million years. Pre-industrial levels were 280 ppm. Our own species, homo sapiens, had never existed when the CO2 concentration were so high.… Read more ›
Trashed landscapes contaminated by depleted uranium or toxic gases. To the eco pragmatist, if you can’t halt war, change to ‘green munitions’ Ruined streets: A rebel fighter retreats for cover as enemy fire targets the position during clashes at the… Read more ›
A comprehensive review of all potential factors behind the 2013/2014 UK winter floods is published today in the journal Nature Climate Change. The paper does not definitively answer whether human activity played a role in the magnitude of the winter… Read more ›
Man, that’s a weird title. But it’s accurate enough. I’ve written about noctilucent (literally, “night shining”) clouds a few times recently. These weird, high-altitude clouds appear to be more common in recent days, and it’s not clear why (global warming… Read more ›
NASA kicked off a new expedition at the top of the world this week to study melting sea ice in order to learn more about Earth’s changing climate. The space agency’s ARISE mission (short for Arctic Radiation IceBridge Sea and… Read more ›
See the video here As international climate scientists warn runaway greenhouse gas emissions could cause “severe, pervasive and irreversible impacts,” the Obama administration is abandoning attempts to have Congress agree to a legally binding international climate deal. The New York… Read more ›
Improving technology is making electrolysis a viable way to store excess renewable energy. Germany, which has come to rely heavily on wind and solar power in recent years, is launching more than 20 demonstration projects that involve storing energy by… Read more ›
From Vogue: “I was never really a marcher,” says Naomi Klein, an author so politically committed that she discovered she was pregnant with her son, Toma, while among Occupy Wall Street protesters in Zuccotti Park. “Even though I believe in… Read more ›
For years, Dr. Ken Caldeira’s interest in planet hacking made him a curious outlier in his field. A highly respected atmospheric scientist, he also describes himself as a “reluctant advocate” of researching solar geoengineering—that is, large-scale efforts to artificially manage… Read more ›
Veteran environment writer John Carey looks at the reasons we don’t seem to make meaningful progress on climate changeand issues a rousing call to arms for us all to step up and play our part When I started covering climate change more… Read more ›
What if there were a simple solution to fighting climate change right under our feet? In her new book, The Soil Will Save Us, journalist and writer Kristin Ohlson says there is. No-till planting is under way at an alfalfa… Read more ›
The world is headed “down a dangerous path” with disruption of the food system possible within a decade as climate change undermines nations’ ability to feed themselves, according to a senior World Bank official. Rising urban populations are contributing to… Read more ›
Humans risk causing irreversible and widespread damage to the planet unless there’s faster action to limit the fossil fuel emissions blamed for climate change, according to a leaked draft United Nations report. Global warming already is affecting “all continents and… Read more ›

By Editorial Board August 25 at 7:00 PM FOR MORE than a century, scientists have understood the basic physics of the greenhouse effect. For decades, they’ve realized humans can affect the climate by burning coal, oil and gas. But the… Read more ›
This article, from NY Times is interesting in that is still describes capping warming at 2C, when we believe that we’re now at .8, and if we stopped all our emissions today at, we would continue to rise to 1.6C, that’s… Read more ›
According to MIT researchers, savings on health care spending and other costs related to air pollution are significant in comparison to the costs of reducing carbon emissions. “Carbon-reduction policies significantly improve air quality,” notes co-author Noelle Selin, an assistant professor… Read more ›
Of all the global warming gasses, methane is one of the very worst. Pound for pound, the Environmental Protection Agency says its effect on global warming is 20 times greater than that of carbon dioxide. And though its lifetime in… Read more ›
The oceans have absorbed almost one-half (approximately 525 billion tons) of human-released CO2 emissions since the Industrial Revolution. Although this has moderated the effect of greenhouse gas emissions, it is chemically altering marine ecosystems 100 times more rapidly than it… Read more ›
A new study is showing that the current rate that we are turning our oceans acidic is quite alarming, possibly ten times faster than it has ever happened in the history of our planet. Ocean acidification is possibly one the… Read more ›
We can pay for it now by dealing with the issue, or later, as problem worsens When it comes to ocean acidification, the state of Washington is in damage-control mode. There is little doubt such acidification has — and will… Read more ›
Algae might seem easy to ignore, but they are the ultimate source of all organic matter that marine animals depend upon. Humans are increasingly dependent on algae, too, to suck up climate-warming carbon dioxide from the atmosphere and sink it… Read more ›
