Scientists present a calendar of global warming
Keywords: warming, climate, planing, developments, dates, estimates
The 2 2005 February, a scientist from the German Research Institute on Climate Change at Potsdam - Germany's largest research institution in this field - has presented a detailed schedule of the effects that climate change is likely to have on the planet.
During a conference in Exeter, UK, Bill Hare outlined the dangers of global temperatures to rise to species, ecosystems, agriculture, water and socio-economic conditions . Developed from a synthesis of recent university studies major, Dr Hare's timetable shows that the effects of climate change are expected to amplify rapidly as an increasing global average temperature.
According to Dr. Hare, our civilization will face huge dangers, environmental refugees crossing borders because of a lack of food and water. This is particularly true for developing countries, he added.
At present, global temperatures are already higher than 0,7 ° C at the pre-industrial era. Over the next twenty five years, when this temperature difference reaches 1 ° C, some ecosystems such as tropical forests of Queensland, Australia, will start to suffer.
An increase in 1 2 ° C temperatures cause fires and insect outbreaks in the Mediterranean region. In the US, rivers may become too warm for trout and salmon, and in the Arctic, melting ice threatens polar bears and walruses.
On top of increased 3 ° C, expected by 2070, the effects will be catastrophic as over 3,3 billion people, or half the world's population will live in countries expected to experience severe crop losses . In many countries, GDP drop will be substantial and the damage to the environment will be enormous, provides Dr. Hare.
Dubbed "Avoiding dangerous climate change", this two-day conference was organized at the call of British Prime Minister Tony Blair as part of a UK effort to raise the issue of climate change among the priorities of the United States. the agenda of the UK Presidency of G8 and the EU. The purpose of the conference is to develop a scientific understanding of the long-term implications of climate change, the importance of stabilization goals and the options for achieving these goals. It also aims to encourage research and international scientific debate on these issues.
