New misguided interpretations of the greenhouse effect from William Kininmonth

Real Climate

Another clue is William Kininmonth’s ‘rethink’ on the greenhouse effect for The Global Warming Policy Foundation. When looking at the effect of changes in greenhouse gases, one must look at how their forcing corresponds to the energy balance at the top of the atmosphere. 679-688, 2016. 679-688, 2016.

Just 25 mega-cities produce 52% of the world’s urban greenhouse gas emissions

Frontiers

New research published by the open access publisher Frontiers inventories greenhouse gas emissions of 167 globally distributed cities. The study shows that just 25 mega-cities produce 52% of the greenhouse gas emissions from the studied cities. For 30 cities, there was a clear emission decrease between 2012 and 2016.

How Canada Can Unlock the Power of Public Transit to Cut Greenhouse Gas Emissions

Enviromental Defense

Our latest report outlines that public transit service levels are now on average, 7 per cent lower than they were in 2016, the year that the federal government began its transit infrastructure funding program. Racialized Canadians account for just over one-quarter (26.5 per cent) of all employed workers, but make up 56.3 million fewer people.

The CO2 problem in six easy steps (2022 Update)

Real Climate

Step 1: There is a natural greenhouse effect. Thus there must be a large amount of IR absorbed by the atmosphere (around 158 W/m 2 ) – a number that would be zero in the absence of any greenhouse substances. Step 2: Trace gases contribute to the natural greenhouse effect. The Earth’s Energy Budget (NASA).

Can GoGreen Advance California’s Home Decarbonization Goals?

Legal Planet

Residential buildings are responsible for about 10 percent of state greenhouse gas emissions, and home decarbonization routinely ranks among the most challenging of our many emissions reduction challenges. Last week, the California Public Utilities Commission released a report evaluating the state’s GoGreen home energy financing program.

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. You might recall that GWP is defined as the ratio on per-kg basis of the temperature impact of other greenhouse gases compared to CO 2 over a specific time period.
