At www.climategate.nl you can read a manifesto that is very critical about the climate agreement as agreed by Dutch politics. I broadly agree with this climate manifesto. I do think however that global warming due to greenhouse gases is going to be a major problem, but it is utterly ridiculous that people think that global warming can be stopped if we achieve the CO2 climate targets as agreed by the politicians.
The greenhouse effect due to CO2 is a physical effect which is easy to quantify. Reducing the current CO2 emissions will not make much difference. The problem, I think, is that the surface of the oceans has already been warmed up a few degrees in the past 100 years. This warming is probably the result of human activities in the past hundred years, but we can not reverse that now. In the past thousands of years, net CO2 has been absorbed by the oceans. In the coming years, however, due to global warming, net CO2 will be released from the oceans. That will be a multiple of all CO2 emissions from human activities. Fortunately there is a delay in these CO2 emissions because most of the CO2 is dissolved at a greater depth where the warming has hardly penetrated. Despite of that we will not be able to prevent the warming of the atmosphere.
Measures must now be aimed at combating the effects of global warming. This will cost a great deal of money and energy and the proposed measures to reduce CO2 emissions are a waste of these resources.
