Global Warming Could Stop Relatively Quickly If Emissions Go to Zero, Research Suggests
Global Warming Could Stop Relatively Quickly If Emissions Go to Zero, Research Suggests A firefighter keeps watch as flames advance along the Western Divide Highway during the SQF Complex Fire on Sept. 14, 2020, near Camp Nelson, California. (David McNew/Getty Images) Parts of the world economy may have been on pause during 2020, dampening greenhouse […]
New research on forests and oceans suggest projections of future warming may be too conservative, with serious consequences
New research on forests and oceans suggest projections of future warming may be too conservative, with serious consequences How much will the world warm with ongoing fossil-fuel carbon emissions? It’s a big question that preoccupies policymakers and activists, with important discussions about when the world will hit two degrees, are we really on a path […]
Climate Campaigners Say ‘Listen to the Science’ as New Study Shows Earth Now Warmer Than Any Time in Last 12,000 Years
Climate Campaigners Say ‘Listen to the Science’ as New Study Shows Earth Now Warmer Than Any Time in Last 12,000 Years The study “changes the baseline and emphasizes just how critical it is to take our situation seriously,” its lead researcher said. A new study published in the journal Nature shows the Earth is now hotter than […]
Is Society Collapsing?
Is Society Collapsing? Abandoned passenger train car, Astoria, Oregon. Photo: Jeffrey St. Clair. Twenty-five years ago, when the high-tech Second Industrial Revolution had just begun, I made a bet with an editor from Wired magazine that global society led by the United States would collapse in the year 2020 from a confluence of causes created by modern […]
Anthropogenic CO2 Emissions are Fate
Anthropogenic CO2 Emissions are Fate Mill, Halsey, Oregon. Photo: Jeffrey St. Clair. I developed a model of Global Warming based on the anthropogenic perturbation of the Carbon Cycle. The essence of this model is a rate equation for the evolution of the carbon dioxide (CO2) concentration in the atmosphere. The interesting results from this model […]
Is there a limit to optimism when it comes to climate change?
Is there a limit to optimism when it comes to climate change? Photo by Lance Cheung/USDA ‘We’re doomed’: a common refrain in casual conversation about climate change. It signals an awareness that we cannot, strictly speaking, avert climate change. It is already here. All we can hope for is to minimise climate change by keeping global average […]
Nobel prize-winning economics of climate change is misleading and dangerous – here’s why
Nobel prize-winning economics of climate change is misleading and dangerous – here’s why While climate scientists warn that climate change could be catastrophic, economists such as 2018 Nobel prize winner William Nordhaus assert that it will be nowhere near as damaging. In a 2018 paper published after he was awarded the prize, Nordhaus claimed that 3°C of warming would reduce global […]
Possible Future Trends of CO2 Concentration and Global Temperature
Possible Future Trends of CO2 Concentration and Global Temperature Wildfire smoke and power line, northern California. Photo: Jeffrey St. Clair. Carbon dioxide gas (CO2) has been accumulating in the atmosphere since the dawn of the Industrial Revolution (~1750), because increasingly voluminous fluxes of that gas have been exhausted from the lands and the oceans, and […]
The Criminology of Global Warming
The Criminology of Global Warming Pulp mill, Longview, Washington. Photo: Jeffrey St. Clair. Some – like Exxon since 1957 – have been aware that the world is facing global warming that has all the signs to render earth uninhabitable. At least with United Nations’ IPPC and NASA reporting on global warming, others have realised that we also face an unprecedented threat. Potentially, all […]
If you can’t stand the heat…get off of the planet!
If you can’t stand the heat…get off of the planet! As I sit in 90-degree heat typical of Washington, D.C. in midsummer and a so-called “heat dome” hovers over much of the United States, I am reading the following: At 11 or 12 degrees [Fahrenheit] of [global] warming, more than half the world’s population, as distributed today, would […]
As warming approaches 1.5°C, talk of a carbon budget for the Paris targets is delusional
As warming approaches 1.5°C, talk of a carbon budget for the Paris targets is delusional There’s a lot of delusional talk about how much “carbon budget” (or new emissions) are allowable that would still keep global heating to the Paris target of 1.5 degrees Celsius (°C). The reality is that over the last year, global […]
Global Warming and Cooling After CO2 Shutoff at +1.5°C
Global Warming and Cooling After CO2 Shutoff at +1.5°C I have done further analytical modeling of global warming, using the same general method described earlier. The question addressed now is: what is the trend of temperature change after an abrupt shutoff of all CO2 emissions just as the net temperature rise (relative to year 1910) reaches +1.5°C, […]
Analysis: How ‘carbon-cycle feedbacks’ could make global warming worse
Analysis: How ‘carbon-cycle feedbacks’ could make global warming worse Scientists making climate-change projections have to deal with a number of uncertainties. The amount of global warming will depend on the magnitude of future emissions, which, in turn, depends on how society grows and develops. The rate of warming will also depend on how sensitive the climate is to […]
Global warming was blamed for evaporating the Great Lakes, now blamed for high water levels in Chicago’s ‘climate emergency’ – Updated 2
Global warming was blamed for evaporating the Great Lakes, now blamed for high water levels in Chicago’s ‘climate emergency’ – Updated 2 “What we are seeing in global warming is the evaporation of our Great Lakes.” That was Illinois Senator Dick Durbin in 2013 when Lake Michigan was at a record low. You can find plenty of […]
