What are the possible consequences of global warming?
Loss of species, increase sea level, loss of lives (human being), etc.
Global climate change has already had observed effects on the environment. Glaciers have gone, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees have been flowering sooner.
Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice and icebergs, accelerated sea level rise and longer, more intense heat waves (especially in large cities). This causes extra deaths especially in metropolitan areas (such as in Madrid, Paris, etc.).
According to the IPCC (Intergovernmental Panel on Climate Change, which includes more than 1,300 scientists from different countries), the extent of climate change effects on individual regions will vary over time and with the ability of different societal and environmental systems to mitigate or adapt to change.
