The CO2 problem in six easy steps (2022 Update)

Real Climate

Step 1: There is a natural greenhouse effect. This means that there is an upward surface flux of IR around (~398 W/m 2 ), while the outward flux at the top of the atmosphere (TOA) is roughly equivalent to the net solar radiation absorbed (~240 W/m 2 ). Step 2: Trace gases contribute to the natural greenhouse effect.

The definitive CO2/CH4 comparison post

Real Climate

So this is an attempt to put all of that in context and provide a hopefully comprehensive guide to how, when, and why to properly compare the two greenhouse gases. There is also a very small impact of the CH 4 oxidation to CO 2 itself for any fossil-fuel derived methane. (a) Historical comparisons. W/m 2 for CH 4.

The summary for policymakers of the Intergovernmental Panel on Climate Change sixth assessment reports synthesis

Real Climate

The term “fossil fuels”, however, is mentioned 16 times. Nevertheless, the summary for policymakers states the need for “rapid and deep and, in most cases, immediate greenhouse gas emissions reductions in all sectors this decade” if we want global warming to keep below 1.5°C C or 2°C since preindustrial times (p.

Climate Change Is Intensifying the Water Cycle, New IPCC Report Finds

Circle of Blue

This trend will continue as glacial melting, decreased rainfall, and a “thirstier” atmosphere jeopardize sources of freshwater in some parts of the globe. It finds more evidence that severe weather events are linked to carbon in the atmosphere and are becoming more extreme. Heavy rainfall will also become more common and more powerful.

Hydrogen and “Renewable” Gas Aren’t Realistic Solutions for Decarbonizing Maine’s Buildings

Union of Concerned Scientists

This included a bill that would have started a statewide conversation about the diminished role fossil fuels should play in Maine’s energy system as the state strives to meet its climate and clean energy commitments. Gas is primarily composed of methane—a fossil fuel with extremely high global warming potential.

WMO: Greenhouse gases will keep rising

A Greener Life

By Anders Lorenzen On the eve of the COP28 UN climate summit, The World Meteorological Organization (WMO), a United Nations (UN) body, has warned that the atmospheric concentration of greenhouse gases (GHG) is forecast to continue the trend that resulted in record-high CO2 measurements last year.

Tornadoes and More: What Spring Can Bring to the Power Grid 

Union of Concerned Scientists

Heightened flood risk The National Oceanic Atmospheric Administration (NOAA) said in a recent outlook that about 44 percent of the United States is at risk of floods this spring, equating to about 146 million people. Fuel transport – Spring floods can hinder the transportation of fuels like coal.
