The Development Of Global Warming Until Now

There is a lot of discussion about whether global warming is progressing or a lie, but in the 150 years since the end of the Edo period when CO2 began to be observed, the CO2 concentration increased by about 100 ppm, but the temperature of the earth was 1 ℃ Only a weak rise.

The history of global warming issues is shown below.
In the first half of the 1980s, NASA ’s Hansen supported Hawaii ’s meteorological observatory CO2 ’s CO2 observation records at the end of the Edo period. American science lined up with British nature as a paper that might cause “global warming” like Venus because CO2 “greenhouse gas” is increasing rapidly from the atmosphere of Venus near 100%. After submitting a paper to the magazine “Science”, the issue of global warming started to fuss.

Hansen just said that the Earth might be warmed from the rise in CO2 concentration and the warmed Venus atmosphere. So I abandoned the honor of being named “greenhouse gas” and “global warming” and withdrew from the global warming issue.

The Global Warming Prevention Convention was concluded in the 1992s, and its research organization, IPCC, advocated the theory of global warming, calculated a global environment simulator program with a supercomputer, and simulated CO2 concentration and global warming. Announced the calculation results that the earth would warm if the atmospheric CO2 concentration increased to 450ppm, 2 ℃, and if it increased to 1000ppm, the Earth would warm.

And since the temperature of the earth began to rise in the second half of the 20th century, IPCC made a fuss about the warming, and the curve of the temperature rise resembles hockey sticks, and IPCC prospered the report. In addition, the IPCC data suspicion problem has highlighted the conflict with global warming skeptics.

However, since the temperature of the earth has fallen since the beginning of the 21st century, the IPCC resets the relationship between CO2 concentration and the temperature of the earth as if there were no previous reports, and a new warming called RCP scenario. I brought a scenario.

And while the Earth's temperature is falling, the Earth's temperature is falling, but the ocean's temperature is rising, so when the Earth is warming, it has become a painful excuse. .

The above is summarized as follows.

There are various discussions about global warming, whether it is a lie, etc., but the CO2 concentration is increasing monotonously, but the temperature is rising or falling, so the CO2 concentration and warming have a low correlation It is considered.

From the end of the Edo period when CO2 began to be observed to the present in the 21st century, the CO2 concentration has increased by about 100 ppm, but the temperature of the earth has risen by just under 1 ° C.

While it is the global warming trend (it is true that there is a warming trend in the short term), it is promising whether it is progressing to the extent that it cannot return in an irreversible direction called global warming.

It is difficult to think that fluctuations will occur at once in a few years when seen on a large scale of the earth, and it seems that it is still unknown even if `` warming '' is correct if you do not see it in a little longer span .
