Scientists have suggested that emissions must be reduced by at least 50 per cent by 2050 to check global warming.
Washington, Dec 7 : Scientists have suggested that emissions must be reduced by at least 50 per cent by 2050 to check global warming.
They have also warned that the world might have as little as 10 years to start reversing the effects of global warming, which makes the need for an immediate cut in greenhouse gas emissions all the more important.
Referred to as the 'Bali Climate Declaration by Scientists', it calls on government negotiators from the 180 nations represented at the meeting to recognize the urgency of taking action against global warming now.
Signatories warn that if immediate action is not taken for fighting global warming, many millions of people will be at risk from extreme events such as heat waves, drought, floods and storms, with coasts and cities threatened by rising sea levels, and many ecosystems, plants and animal species in serious danger of extinction.
In order to check this bleak scenario, the Bali Declaration emphasises the current scientific consensus that long-term greenhouse gas concentrations need to be stabilised at a level well below 450ppm CO2e (450 parts per million measured in carbon dioxide equivalent).
It also endorses the latest scientific consensus that every effort must be made to keep increases in the globally averaged surface temperature to below 2 degrees C. The scientists say that "to stay below 2 degrees C, global emissions must peak and decline in the next 10 to 15 years".
"Climate change is unfolding very fast. There is only one option to limit the damages: stabilise the concentration of CO2 and other greenhouse gases in the atmosphere," said Prof Le Quéré. "There is no time to waste. I urge the negotiators in Bali to stand up to the challenge and set strong binding targets for the benefit of the world population," he added.
So, it becomes important for negotiations at Bali to start the process of reaching a new global agreement that sets strong and binding targets and includes the vast majority of the nations of the world.
"As scientists, we urge the negotiators to reach an agreement that takes these targets as a minimum requirement for a fair and effective global climate agreement," the Bali Declaration concluded.
