Climate change issues

Global warming comprises a phenomenal worldwide increase of the average temperature of oceans and atmosphere over many years.

The existence of this climate change has been published by reports prepared by over 600 climatologists of the Intergovernmental Panel on Climate Change, coming from all over the world and supported by governments worldwide.

In 1994, the hypothesis of a link between average global temperature and the level of carbon gases in the atmosphere was announced for the first time. In 1979, the first worldwide climate conference proposed, for the first time in the international scene, the probability that human activity has an impact on climate. Today, it is universally recognized that the causes of global warming can be attributed to human activity and, in particular, the emissions of greenhouse gases.

Global warming affects both average sea levels and global precipitation patterns. The thermal expansion of the oceans, added to the melting of glaciers, could lead to a substantial increase in average sea level, which would noticeably decrease the land area in regions near or under sea level (which are often very populated). Changing precipitation patterns could also have a substantial environmental impact, as some areas become dryer while others become wetter.
