I am really concerned that we may be causing irreversible and harmful climate change.
While there is no conclusive proof that humankind is behind global warming, the evidence against us is stacking up more and more heavily.
The planet has some amazing mechanisms for keeping the environment stable, such as soaking CO2 up in the oceans, but these are not infinitely flexible and we may be approaching a tipping point. As an illustration of this, consider a glass filled with water and ice cubes, standing in a warm room. The ice/water mixture stays at 0 degrees as the ice gradually turns to water, but once all the ice has melted the temperature rapidly rises.
While we have not proved that our wasteful use of fossil energy is causing global warming, there is ample evidence that using a lot less won't cause any harm and may in fact stimulate the economy. So it would be logical to reduce our emissions of both greenhouse gases and waste heat as quickly as possible.
More research is needed to identify renewable energy sources that are much more efficient and less environmentally damaging than wind turbines or biofuels. Better insulation and more efficient heating, manufacturing, agriculture and transport are also needed.
Right now, the President of the EU Commission, Jose Manuel Barroso, is weighing a decision that could make or break our planet. His team have just days to pin down carbon emissions and renewable energy targets for Europe until 2030. It’s a very important deal that has been kept very quiet. Some EU countries, prompted by vested energy interests, are lobbying to set extremely unambitious targets. Barroso may opt to avoid a fight by playing it safe. He works in a bubble of politicians, officials and lobbyists, but he is very sensitive to what people think of him, especially now as he embarks on his last few months in the job and hopes to leave a shining legacy.
Avaaz is publishing an ad in the key Brussels paper today calling on Barroso to follow the science. If supported by tens of thousands of e-mail messages from across Europe, this could just jolt him out of the bubble. You can read the ad and send Barroso a message today that the the future of the world is in his hands.
