A ‘world climate statement’ that denies climate emergency makes misleading claims

A 'world climate statement' that denies climate emergency makes misleading claims

2.”The world has warmed far less than the IPCC predicted based on forced anthropogenic modeling… Climate policy relies on inadequate models, baseless

Since the first report, the IPCC’s estimates have still proved correct, Javier Fattweis explained to AFP in early August. ,When we look at the IPCC estimates of the 2001 and 2007 reports, anticipated warming is exactly what we see“, said the climatologist this check item,

Many climatologists have compared IPCC experts’ estimates to actual observed temperatures, Already Explained Liberation in 2019.

Thus, a. author of Article published on the Carbon Brief platform (funded by the European Climate Foundation) estimated in 2017 that “Climate models published since 1973 have generally been quite good at predicting future warming. While some were very low and others were very high, they all show results close to what actually happened, especially when discrepancies between projected and actual CO2 concentrations and other climate pressures are taken into account.,

In first chapter According to the IPCC’s Sixth Assessment Report, the scientists compared estimates of temperature curves from the group’s previous reports with those of several climate scientists – such as sukuro manabe where James Hansen – And the temperature was actually observed.

It can be seen that the estimates correspond fairly well to the temperatures actually observed, with a difference not exceeding 0.2 °C.

3.”The increase in CO2 is good for the green nature of our planet. Increase in CO2 in the air has fueled the growth of global plant biomass, misleaders

The argument that CO2 is beneficial to nature is based on a confusion between organic CO2 and CO2 emitted by human activities, as detailed in this article of verification.

CO2 is actually a so called gas “Natural”Like water vapor, that is, it was present in the atmosphere long before man appeared on the planet.

,there are Sure Part of what is the carbon cycle Natural“In June, Sonia Seneviratne, professor of climate science at the Swiss Federal Institute of Technology in Zurich, explained to AFP.”If we don’t burn fossil fuels, there will inevitably be CO2 in the atmosphere. For example, plants capture CO2 through photosynthesis. Then during their decomposition CO2 is emitted again. these are natural phenomena“, she adds.

This gas also participates in the functioning of our body: “When we breathe, we take in oxygen and release CO2.”, confirms Pierre Friedlingstein, carbon and climate expert, research director at ENS.

,Problem“, emphasizes Sonia Seneviratne,”is that we now have an additional supply of CO2 in the atmosphere Which comes from the combustion of old plant waste: oil, gas or coal. Originally there were plants that captured the CO2 in the organic form, which had accumulated on the planet. When they are burned, an additional contribution of CO2 is released into the atmosphere. which will remain there for hundreds of thousands of years, And since it’s a greenhouse gas, it creates an imbalance in our climate system.”

,with fossil fuels, We emit CO2 that was removed from the atmosphere millions of years ago and which we now re-inject : it only brings CO2 back to where it was 50 million years ago“, completed Pierre Friedlingstein.

so CO2 is not dangerous, but When its concentration in the atmosphere is high, it contributes to global warming in the same way as methane or nitrous oxide, which are also greenhouse gases (GHGs).

,As the Earth heats up as a result of solar radiation, it emits heat in response, which radiates back into space. Greenhouse gases block this heat from being released like a blanket. The more GHGs there are, the thicker this blanket will be. so we have an increase in temperature“, elaborated Sonia Seneviratne.

This increase in Earth’s temperature has harmful and dangerous effects on biodiversity, populations, agriculture and even water resources.

According to experts cited in this article According to the German-speaking AFP verification team, plants can really only deal with a limited portion of the additional carbon dioxide emissions, and are suffering from the effects of climate change.

IPCC Reporters indicate in their final report He If climate change continues at the same pace, these effects, which can already be observed for many years, will continue to multiply and intensify.
