How to stop climate change.


Hi.. this is a new entry to show you guys that our world is in danger and we should do something about that very soon.. In my opinion we should focus first in this than anything else.. because we only got one world to care about

STEP ONE: Stop debating, start doing

Although there is now a very broad consensus on climate in the media and politics, opinion polls show that many people still harbour doubts about climate change. One of the peculiarities of the climate debate is that although more than 99 per cent of international climate change scientists agree on the causes of global warming, the denial lobby still only has to produce one contrarian to undermine the consensus in the public mind. Similarly, changes in our understanding can be magnified and distorted to suggest that, because we don't know everything, therefore we must know nothing. Thus, data from one glacier that apparently bucks the global trend can be wielded as a trump card against all the accumulated knowledge of climate science.

STEP TWO: Focus on the big wins

But this is a long-term agenda, and we don't have much time. Hence my second proposal, which is for a much clearer focus on win-win strategies for immediate emissions reductions. These are things we would want to be doing anyway, even if global warming had never been thought of. Reducing deforestation in the tropics is a big win-win. Inherently desirable, this by itself would reduce global carbon emissions by 10 per cent or more. All it takes is money: we have to pay countries such as Brazil and Indonesia to leave their forests alone rather than chop them down to sell to us as plywood and furniture.

There are obvious win-win strategies in the domestic sector. Better insulation makes living conditions more comfortable and reduces fuel bills. Even without climate change we'd still want to be getting cars out of town centres to reduce air pollution and improve the urban experience. Getting more children to walk and cycle to school improves their physical health and helps to tackle obesity. Enforcing speed limits (and reducing them further) would save hundreds of lives a year, and give some respite from the incessant noise pollution of speeding traffic.

STEP THREE: Use technology

But there are some areas of high-carbon behaviour that people will always be reluctant to give up, and this brings me to the third and final part of my strategy to deal with global warming - technology.

Today we face a situation where a global population of potentially nine billion or so by 2050 continues to demand a steadily increasing consumer lifestyle. There is nothing we can do to stop this, and nor should we try. But it does put humanity on a very real collision course with the planet, so we are going to have to throw every technological tool we have at the problem to try to meet people's aspirations without worsening our climatic predicament. Some of this will involve technology leapfrogging: helping developing countries skip over our dirty phase of industrialisation, by instal ling solar power in remote, off-grid areas of Africa and Asia, for example. We also need to help developing countries make choices that put fossil fuels at the bottom of the energy shopping list, by helping them use carbon capture and storage technology as well as nuclear power. Both have obvious drawbacks, but I would rather see China building two nuclear reactors a week than two coal-fired plants.

Ending it!

In my opinion is hard for us to descrease our demand to the world.. we should focus our technology to protect our world because is the only one we have.. so why don't we make the technology to not hurt our world..
