ABSTRACT
The use of the term climate change was itself controversial, and a new group soon emerged of climate change sceptics or deniers. Such people either said that the climate wasn't changing, accusing scientists of fiddling the data, or asked, given that climate changed naturally, what was the evidence that human activity was the cause. There are some predictable shifts that contribute to regular changes to climate. The climate someone have depends on where someone are on the Earth, and might be summed up as the long-term weather pattern in a region, particularly in terms of sunshine, temperature, wind and rainfall or snow, and how these vary on a seasonal and yearly basis. The UN's Intergovernmental Panel on Climate Change says it is. It notes that since the 1950s, there have been unprecedented changes to the climate: the atmosphere and ocean have warmed, the amounts of snow and ice have diminished, and sea level has risen.
