CO2

Jack Marley | – The world has the means to avert the greatest ravages of global heating – but we must deploy them immediately, while eliminating the fuels and activities that threaten to warm Earth beyond safe levels. This is the conclusion of a new report by the Intergovernmental Panel on Climate Change (IPCC), a […]

In 20 years of studying how ecosystems absorb carbon, here’s why we’re worried about a tipping point of collapse

By Caitlin Moore, David Campbell, Helen Cleugh, Jamie Cleverly, Jason Beringer, Lindsay Hutley, and Mark Grant | – From rainforests to savannas, ecosystems on land absorb almost 30% of the carbon dioxide human activities release into the atmosphere. These ecosystems are critical to stop the planet warming beyond 1.5℃ this century – but climate change […]

Industrialized Nations must stop Producing Fossil Fuels by 2034 to keep Climate from Going Tropical and Chaotic

Ann Arbor (Informed Comment) – Scientists Dan Calverley and Kevin Anderson at Manchester University have brought out a new report looking hard at what would have to be done for us to have a 50/50 chance of keeping the increase in the average temperature of the earth’s surface to 2.7 degrees F. (1.5C) over preindustrial […]

Ann Arbor (Informed Comment) – The UN Intergovernmental Panel on Climate Change has issued its 2022 report and the scientists have bad news for us. This report is far more pessimistic than its predecessors. The climate emergency is being caused by humans burning coal, petroleum and methane gas for electricity and heating and cooling buildings. […]

Climate-Driven Heat Waves stop Carbon Absorption by Forests like Tasmania’s Eucalyptus Stands

By Tim Wardlaw | – Southern Tasmania’s tall eucalyptus forests are exceptionally good at taking carbon dioxide from the atmosphere and converting it into wood. For many years, we have believed these forests had a reasonable buffer of safety from climate change, due to the cool, moist environment. Unfortunately, my research published today shows these […]

Not Since Charlemagne: Megadrought in US Southwest, boosted by Human CO2 emissions, is worst since 800 AD

Ann Arbor (Informed Comment) – The megadrought in the US West has produced drier conditions as of the past year than any seen in over 1,200 years, according to a just-published article in Nature Climate Change by scientists A. Park Williams, Benjamin I. Cook and Jason E. Smerdon of UCLA. The length and intensity of […]

We need to cut Carbon, not fall for the Scam of Trying to Capture it

By Jason MacLean | – When the federal government released the budget in April 2021, it proposed creating a new tax credit for private firms that make investments in carbon capture, utilization and sequestration projects. But in January, shortly after the consultation period closed, more than 400 Canadian climate scientists, academics and energy system modellers […]
