T e trend towards warmer average surface temperatures for the period since 1976 is roughly three times that of the past 100 years as a whole. In the last decades warming seems to be attributable to human activities (man-made environmental changes) like land-use changes, deforestation, urbanisation and the reduction of wetlands. Global climate change is likely to be accompanied by an increase in frequency and intensity of extreme weather events.
