Deciphering the ‘SPM AR6 WG1’ code

Real Climate

Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below). The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

Don’t Believe the Lies: Five Facts to Consider as the UN’s COP27 Comes to a Close

Union of Concerned Scientists

Their study examined the carbon dioxide and methane emissions from these companies’ products, as well as from the extraction and production processes of the largest gas, oil and coal producers and cement manufacturers. Data on the major carbon producers’ emissions have been published since 2014.

New, Updated Carbon Majors Dataset Holds Promise for Researchers, Litigators

Union of Concerned Scientists

That 2013 headline resulted from the first effort to quantify emissions from the ‘carbon majors’ —fossil fuel companies and cement manufacturers whose businesses have contributed an outsized amount of heat-trapping gases to the atmosphere.

Now however, the updates to the historical warming , the use of four datasets instead of one, and of course, the series of record breaking years subsequently (2014, 2015, 2016/2020), the issue of variability in decadal trends is no longer so salient.

Oil Refineries: A Deadly Industry

Union of Concerned Scientists

Fossil fuel combustion produces carbon dioxide (CO2), the most abundant global warming pollutant, but also produces local pollutants such as fine particulate matter (PM2.5), nitrogen oxides (NOx), carbon monoxide (CO) and volatile organic compounds (VOCs). which is formed in the atmosphere from precursor gases such as NOx.

Carnegie Museum Of Natural History: We Get Questions - Climate Change, Hope And Action

PA Environment Daily

The frightful phenomenon is on a scale proportional to and correlated with the climate altering changes in Earth’s atmosphere. Gases from the atmosphere get absorbed by the ocean and gases dissolved in the ocean are released into the atmosphere.

Tackling Agricultural Methane: An Overview of the Science

Legal Planet

Because methane has 28 times the global warming potential of carbon dioxide and a shorter atmospheric life of only 12 years, immediate action to reduce methane emissions —including from agriculture—is critical to slow our warming climate, especially in light of expanding global populations and food demand. 2018 , Petersen et al.,
