WHAT IS GLOBAL WARMING?<br />Global Warming is the increase in temperature of Earth’s wear-surface, air and oceans <br />
Most of the observed temperature increase has been caused by increasing concentrations of greenhouse gases, which result from human activity. <br />
It supposed that the global surface temperature is likely to rise a furter 1.1 to 6.4°C during the 21st century. <br />
How can it change our world?<br />Global Warming will cause: <br /><ul><li>sea levels to rise
the amount and pattern of precipitation, probably including expansion of subtropical desorbs
changes in the frequency and intensity of extreme weather events
changes in agricultural yields </li></li></ul><li>… and then…<br />Warming and related changes will vary from region to region, though the nature of these regional variations is uncertain.<br />As a result of contemporary increases in atmospheric carbon dioxide, the oceans have become more acidic, a result that is predicted to continue… <br />
What do people think about it?<br />The scientific consensus is that anthropogenic Global Warming is occurring. <br />Nevertheless, political and public debate continues.<br />The Kyoto Protocol is aimed at stabilizing greenhouse gas concentration to prevent a “dangerous anthropogenic interference” .<br />In 2009 187 states had signed and ratified the protocol.<br />
There are different views over what the appropriate policy to climate change should be.<br />In general it seems likely that climate change will impose greater damages and risks in pooper regions. <br />But…<br />
Nick Pidgeon of Cardiff University said “results show the different global warming on each side of the Atlantic”, adding “the debate in Europe is about what action needs to be taken, while many in the USA still debate whether climate change is happening” <br />
So, <br />THE PLANET IS NEATING UP – AND FAST!<br />
