Cyclone(Reuters) - Witnesses to Cyclone Yasi's destructive tear across northeastern Australia described it as a monster for its size and ferocity. It was also an omen.

Climate scientists say global warming is heating up the world's oceans and atmosphere, providing more fuel for tropical cyclones and creating ever greater risks for crops, miners and billion-dollar beachfronts.

The risks from stronger storms flow right through the heart of the global economy, affecting food security and inflation, iron ore and coal production and higher insurance losses.

Particularly vulnerable are Asia's booming coastal megacities from Manila to Karachi, large areas of the U.S. Gulf and east coast, Australia's iron-ore and northern coal mines and tropical Asia's rice-growing river deltas.

GlobeClimate change, the shifting temperature of the earth due to amplified levels of atmospheric greenhouse gases (GHGs) from fossil fuels and deforestation, is currently a topic of heated discussions worldwide. In 2007, the Intergovernmental Panel on Climate Change, a United Nations organization, stated that “warming of the climate system is unequivocal” [1].

GHGs persist in the atmosphere for hundreds of years [2]. Climate change is thus a very unique issue as its effects transcend time and space: GHGs emitted now in any location will affect the whole planet for many generations to come. Therefore, the generation that knowingly creates negative climate change should make every effort to reduce that impact; this represents a moral choice.

REDDJOHANNESBURG, 28 January 2011 (IRIN) - Forests help sustain life on earth by absorbing carbon dioxide from the air, and also provide a home to many communities that depend on them, yet they become one of the biggest sources of harmful carbon dioxide when they are destroyed. 

An imbalance in the perceived value of forests drives deforestation, which contributes between 12 percent and 20 percent of the world’s annual greenhouse gas emissions - about the same as the transport sector, according to the Intergovernmental Panel on Climate Change (IPCC). 

“Forest areas are often worth more harvested than left standing,” said Manish Bapna, managing director of the World Resources Institute (WRI), on the website of this US-based environmental think-tank.
