3°C at 2100, you are dreaming. In Europe we are already at 1.7°C
The Paris agreements require a 5% reduction in CO2 emissions per year to be at 0 in 2050
The global containment of 2020 is a 7% reduction in emissions.
The 5% is and will never be required. The fight against climate change has never existed and will never exist.
Robert Charney wrote in 1979 in the first report of what was not yet the IPCC: if we do nothing in 1979, it will be too late when we see it.
Climate change does not exist. It will soon be forbidden to talk about it under penalty of repression.
for an emissions scenario leading to more than +4°C in 2100, about 74% of the world's population will face life-threatening temperature and humidity conditions more than 20 days a year.
For the same emissions scenario, the working capacity will be reduced by less than 60% on average for the world population, during the hottest months in 2100.
In its Sustainable Development Scenario (supposed to be compatible with the objectives of the Paris Agreement), the IEA estimates that, by 2040, the global demand for nickel and cobalt linked to the energy transition could be multiplied by 20 approximately and that of lithium by more than 40.
In concrete terms, the share of "low carbon energies" in the world demand for minerals could, by 2040, reach 45% for copper (compared to 24% in 2020), approach 60 to 70% for nickel and cobalt ( against respectively 8% and 15% in 2020) and exceed 90% for lithium (against 29% in 2020).
CO2 has been in the atmosphere for millennia. 3°C in 2100, this is madness and the industrial world live in a bubble
