Climate change is a threat to human security. As pointed out in the Fourth Assessment Report prepared by the Intergovernmental Panel on Climate Change, it produces changes in the patterns of hydrological cycles, which in turn produces: an increase in the frequency and severity of drought, with associated changes in the already difficult food supply-demand balance, a loss of human life and property and health problems due to water-related disasters such as floods and landslides: an increased risk of tidal waves/water damage and loss of lands caused by the rise in sea level, an increased likelihood of glacial lake bursts: declining water quality due to elevated water temperatures: and changes in water ecosystems. Thus, changes in hydrological cycles caused by climate change will pose a grave threat to both developed and developing countries |
