We must not be dependent on uncertain computer models to ascertain climate sensitivity
ISLAMABAD: There is certainly no dispute between scientists and environmentalists regarding the fact that the climate changes, and does so for many reasons. In fact, the past century witnessed two distinct periods of warming and cooling. Humans are causing global warming — is the position of the Academies of Science from 80 countries plus many scientific organisations that study climate science. But there has yet been no consensus.
A Petition Project features over 31,000 scientists signing the petition, stating that, “There is no convincing scientific evidence that human release of carbon dioxide will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere”. They argue that climate is always undergoing change, and the changes due to increasing CO2 are smaller than the natural variability of climate. We must not be dependent on uncertain computer models to ascertain climate sensitivity. It is further noted that the common assertion that even small changes in mean temperature can lead to major changes in climate distribution may be an unclear assumption.
Nations are abandoning the UN’s climate hype-promoted Kyoto carbon emission reduction commitments in droves as its intergovernmental panel on Climate Change struggles to explain why its model-based predictions have been spectacularly disproven by Mother Nature.
