The English Prime Minister, Gordon Brown, wrote an article for the magazine Newsweek on September 28th, 2009 on the importance to reach an world agreement on the climate change at the top of United Nations in Copenhagen 11 weeks later.

Indeed, some reasons are pushing him to act for the future of the planet. Ecological threats (pollution), environmental (drought) but also humanitarian workers (famine) and economic (decline of the harvests and the commodities) are omnipresent and he thinks that we won’t have a second chance in the future to change things. Climate change will be inevitable and we expect sea level to rise as the ocean takes up heat and ice starts to melt which will entail floods, destructions, poverty and diseases.

To face all these problems which will increase from years to years, G. Brown proposes solutions such as investments by countries in the "green technology", to facilitate the electric motor cars’ sales to reduce CO2 emissions, to use more wind turbines and the tides’ current to make some electricity, " limit the rise to two degrees Celsius " for global warming.

However the proposed actions are going to meet obstacles. The main difficulty is the economic crisis which has just touched all the countries. But there is also another major problem; it is the developing countries which utter tons of CO2.

Furthermore, those actions are practicable thanks to, on one hand, the Copenhagen Climate Conference which gathered the powerful countries and on the other hand thanks to the waves of innovations and the millions of jobs in the environmental sector. In it is added all the investments brought by countries and private sectors as well as the new growth.

To conclude, if the world leaders do not agree from now on, the catastrophic damages caused to the environment will be impossible to change. That's why it's essential that they find an international agreement on the climate change at the Copenhagen
