Earth’s 2/3rd area is occupied by ocean where there is negligible human interference in terms of emission of green house gases. Large area of earth’s 1/3rd land is occupied by dense forests, mountains, water bodies etc where there is negligible human interference in terms of emission of green house gases. Only a small area of earth’s land (≤ 5%) is occupied by dense human population where human interference in terms of emission of green house gases is significant. As far as emission of green house gases is concerned whether during Second World War it was maximum or for last 3 decades? Now question is that ‘whether such a negligible amount ≤ 5% of urbanization emitting green house gases (Human interference) is responsible for global warming in turn resulting in climate change?'
Dear Prasann,
It is a false argument that people have not contributed to global warming because the area of the planet that is densely occupied is a relatively small proportion of the total. John is right about the evidence for the human contribution to greenhouse gas emissions being overwhelming, as presented in the IPCC 5th assessment report. Another small, but compelling piece of evidence is in the attached paper by Kokic et al.
I couldn't help wondering whether your colleagues at the Indian Meterological Office agree with your opinion? Kind regards, Matt
In my recent papers I have proven that climate variability is almost exclusively solar originated so CO2 has nothing to very little to do with it.
