Everywhere in the world is changing... not all is to become better but worst. The global weather is changing drastically. A lot of places are in danger!
One of the danger is GLOBAL WARMING!
Brazil plays an important and unique role in climate change. It is one of the ten largest economies in the world and — most importantly for climate change — home to one of the greatest ecosystems and forests of the planet: the Amazon. Brazil is the eighth largest emitter of greenhouse gases, and the third largest emitter in the developing world after China and India, according to 2000 World Resources Institute figures. Unlike most developed and many developing countries, Brazil's energy sector contributes little to the country's greenhouse gas emissions. Unsustainable land use and forestry contribute most.
Brazil's track record in renewable energies is an example to many. Brazil is the world's largest producer and also consumer of ethanol, which it has added to gasoline since the 1970s. This has reduced both greenhouse gas emissions and pollution in urban centres, where more that 80 per cent of the 180 million Brazilians live.
Africa has contributed less than any other region to the greenhouse gas emissions that are widely held responsible for global warming. But the continent is also the most vulnerable to the consequences. Researchers predict that warmer temperatures will make sand dunes in southern Africa unstable, with serious implications for farmers whose livestock graze there.
Researchers warn that climate change will threaten food security in developing countries — especially in Africa and Asia.
Whalers kept records of where they met the floating ice shelves which surround much of Antarctica - way back into the 1930s. This was at a time when there were no satellite photos to show how big the ice shelves were. You didn't have those till the 1970s. What the whaling records tell us is that the sea ice has melted away drastically over the last 40 years or so. Collapsing Antarctic ice shelves is already happening. Huge chunks of floating ice the size of whole counties (1300 square kilometres in 1995) have broken off and floated away. Great cracks have appeared in other shelves like the Larsen B shelf in the Antarctic peninsula. This area has warmed 2.5° Celsius since the 1940s and has lost four of its ice shelves. Some people worry that parts of the thick ice sheets covering Antarctica could become unstable because of warming and rising sea levels.
So please plant more trees to reduce global warming... Thanks for saving EARTH and US!
