Conclusions
If one looks at the facts and observations of global warming, it is only possible to conclude that the Earth is warming and that humans are primarily responsible. Therefore the only “unknowns” are how much the Earth is likely to warm both in the near term and in the long term and how the climate is likely to change. The “near term” forecast is not promising, particularly since there is not even a hint that global leaders are taking the problem seriously.
