What do you think about our new web site?

Love it, indeed
Really good solution
Same as old one
The old one was better
This is a new option

Quote of the day

People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Geoengineering plan could have 'unintended' side effect

RATE THIS! +33

Attempts to reverse the impacts of global warming by injecting reflective particles into the stratosphere could make matters worse, say researchers. A new study suggests the idea, seen as a last-ditch way to deal with runaway climate change, could cut rainfall in the tropics by 30%.

 
This would have devastating impacts on rainforests in South America and Asia.The research has been published in the journal Environmental Research Letters.
 
The concept of curbing rising temperatures by blocking sunlight has been discussed by scientists for many years now.
 
Some of the ideas have been dismissed as crazy notions, but others have been taken more seriously.
 
One of the most credible plans involves using reflective particles called aerosols to reflect solar radiation away from the Earth.
 
This happens naturally when volcanoes erupt, sending plumes of ash into the stratosphere, as with Mount Pinatubo in the Philippines in 1991.
 
Now a team at the University of Reading have modelled the impacts of a large-scale injection of sulphur dioxide particles at high altitudes around the equator.

Tackling climate change needs many approaches. Furthermore they have to be assessed very carefully as making any mistakes would be catastrophic

This is completely new. At present, these injection technologies do not exist, even on paper, and this precludes an evaluation of realistic effectiveness or side effects. Reply

Researchers around the world continue to explore different climate interventions that might be used in extreme circumstances. The Intergovernmental Panel on Climate Change in their recent report acknowledged that every option should be considered. Reply

Climate change is a serious issue. Recently Panel on Climate Change said that global warming carries risk of deep changes. At the same time, some worst-case fears about climate change can be ruled out as unlikely

While most climate scientists believe the human release of greenhouse gases has made immense changes in the earth inevitable, they hope many of these will happen slowly enough that society can adapt. Reply

This could seem comforting. The fact that there is no global catastrophe looming in the near future is a good news, however could send a wrong message.

Nasty climate surprises have occurred already, and more seem inevitable, perhaps within decades Reply

I agree, we should not relax and stop all regulations and measures to reduce global worming due to human activity. If we stop, this prediction may soon change Reply

It is a god thing that there are international talks on this topic and no one would like to stop further talks and agreements. However, this remains very complex and difficult and we should not relax this effort in a view of this analysis

At a recent conference the problem was that China and India clashed with the developed countries by insisting that rich countries continue to operate under stricter standards than poor countries. Avoiding impacts on economic growth seem to be the main goal for all involved Reply

Climate financing is hard to agree on. Rich countries have promised to help developing nations make their economies greener and to adapt to rising sea levels, desertification and other climate impacts. They have provided billions of dollars in climate financing in recent year Reply
