A recent study of climate change, published in Scientific Reports, a Nature journal, which suggests that global warming is now irreversible and that the earth is past the tipping point on climate, has caused alarm, and also scepticism, and even anger. The study is based on a model developed by Norwegian researchers who charted changes in climate from 1850 to 2500. Two scenarios were envisaged, one in which there is immediate achievement of zero greenhouse gas emissions and another in which gradual reductions are made till 2100. It was found that the earth will continue to warm over the next five centuries and it will be warmer by 3.0 degrees Centigrade by 2500. The only difference between the two futures is that the extreme situation will happen faster in the second scenario. The conclusion is that the earth is set to get hotter, whether the emissions are cut or not. Many scientists have found fault with the study on various grounds. Modelling need not be accurate, especially if the inputs are not correct. Many factors that influence climate are still not known and there is a paucity of data on events of the past. It is not possible to predict climatic events of the coming …
