There are three statements by major scientific organizations that provide a valuable lens through which to view the climate crisis.
“(T)he amount of rise in carbon dioxide levels since the late 1950s would naturally, in the context of past ice ages, have taken somewhere in the range of 5,000 to 20,000 years; we’ve managed to do it in about 60.” (National Oceanic and Atmospheric Administration)
Although Earth’s climate has changed before, it’s the pace of the current change that’s most troubling.
“Climate change resulting from anthropogenic CO2 emissions and any associated risks to the environment, human health and society, are…essentially irreversible on human time scales.” (Fourth National Climate Assessment, U.S. Global Change Research Program)
About half of the carbon dioxide we emit stays in the atmosphere for centuries or more.
The United States is the greatest cumulative emitter, with twice the historical emissions of second place China. Given the long residence time of CO2 in the atmosphere, this means the U.S. is responsible for a larger percentage of the current CO2 concentration than any other nation.
“Limiting global mean temperature increase at any level requires global CO2 emissions to become net zero at some point in the future.” (Global Warming of 1.5°C, Intergovernmental Panel on Climate Change)
Net zero carbon dioxide emissions means reducing emissions enough that they are balanced by CO2 removal, such as being absorbed by forests and dissolved in the oceans, otherwise the concentration of carbon dioxide in the atmosphere will continue to grow.
Terri, I have read your remarks before and have found them unbelievable for many reasons, but thanks anyway for offering them for consideration.
My preferred sources for the real facts on the causes of global warming are located in Flagstaff at both the university, NAU, and the renowned Lowell Observatory. As maybe you know Lowell is world recognized for the expertise of their leader, Jeff Hall, and staff. That happens because they have the telescope equipment to look into the universe where all this heat is coming from ( the sun in our case ) a fact which eludes too many if not all so called scientists and wana be experts.
A summary of their opinions on how we all should cope and act to mitigate the increases in the temperatures is do not have the government create laws and regulations for this purpose because these measures never have nor will they ever work.
Terri it would help you if you just quit following the Al Gore gang.
