The above link is to an interesting study by Professor Roy Spencer. He says: Net Zero assumes that human CO2 emissions must stop to halt the rise in atmospheric CO2. This is false. nature removes atmospheric CO2 at a rate based upon the CO2 content of the atmosphere, and as long as that remains elevated, nature continues to remove CO2 at a rapid rate. Satellite-observed “global greening” is evidence of that over land. Over the ocean, sea water absorbs CO2 from the atmosphere in proportion to the difference in CO2 partial pressures between the atmosphere and ocean, that is, the higher the atmospheric CO2 content is, the faster the ocean absorbs CO2.

Here are three sources supporting net zero. 2/3 of the warming has occured since the 1970s. Global warming has accelerated strictly due to increased GHGs in the atmosphere.
ReplyDeleteRoy Spencer was a at one time an honest scientist. That's not the case any more. The field of climate science now ignors him.

The evidence is clear: the time for action is now. We can halve ... - IPCC
For 1.5°C (2.7°F), this means achieving net zero carbon dioxide emissions globally in the early 2050s; for 2°C (3.6°F), it is in the early 2070s. This assessment shows that limiting warming to around 2°C (3.6°F) still requires global greenhouse gas emissions to peak before 2025 at the latest, and be reduced by a quarter by 2030.

The Latest IPCC Report: What is it and why does it matter?
Mar 20, 2023The IPCC is the scientific group assembled by the United Nations to monitor and assess all global science related to climate change. Every IPCC report focuses on different aspects of climate change. This latest report is the IPCC's 6 th Synthesis report. It updates and compiles in one report findings from all the reports in the IPCC's sixth ...

The What, When, and How of Net-Zero Emissions - World Resources Institute
Mar 20, 2023Here we unpack what net-zero greenhouse gas emissions really means, and why these goals are important to fighting the effects of climate change. ... The different pathways assessed by the IPCC to achieve 1.5 degrees C all rely on carbon removal to some extent. Removing CO2 from the
You write: "The IPCC is the scientific group assembled by the United Nations to monitor and assess all global science related to climate change." You are wrong, the IPCC was set up to look at the human causes of climate change due to global warming. They ignore all other causes which is why they are completely one-sided and cannot be relied on.
DeleteThis is a gathering of the studies of human vs natural causes. Humans are the clear cause of warming on earth. Natural would actually be cooling.

A wide variety of statistical and physical approaches all arrived at the same conclusion: that humans are the dominant cause of the global warming over the past century, and particularly over the past 50 years. This robust scientitic evidence is why there is a consensus amongst scientific experts that humans are the dominant cause of global warming.
