Should we be concerned about global warming?

We should all be concerned about global warming because of the harm it can do to our planet, our society and our economy. Global warming threatens climate change that will result in widespread species extinction, droughts in some areas but more frequent severe floods in others, sea level rises that, along with higher storm surges, could result in entire populations having to abandon their homes, and more intense storm activity that will cause economic hardship.

The Arctic Climate Impact Assessment, an international project of the Arctic Council ( a high-level intergovernmental forum) and the International Arctic Science Committee (IASC), created for evaluating and synthesize knowledge on climate variability, climate change, and increased ultraviolet radiation and their consequences, have arrived to the conclusion that the concentration of greenhouse effect gases and the rising of temperatures will cause the melting of the ice caps, the rising of sea levels, increased storms, decreased water in lakes and rivers, radical changes in weather behavior, reduced animal health, increase of insects population and drying of wetlands and other inland areas with simultaneous floods and increased rain in coastal regions.
