Many scientists think that
the Earth is getting warmer and warmer. If the change continues, the natural
world and human society will face danger. Scientists believe human activity is
responsible for the climate change. We produce too many greenhouse gases. They
keep heat in the air and make the Earth warm.
Many of the world's
governments agree. And they want to solve the problem. So from 7 to 18
December, 2009，they held a conference in Copenhagen,
Denmark to talk about global warming and climate change.
Representatives(代表) from 192 countries and regions went to the meeting. Although they
have not reached an agreement, the Copenhagen Accord(《哥本哈根协议》) was an important beginning to save the Earth. It was made by a
small group of countries including China，the USA，India, Brazil and South Africa. Some other countries at the
conference also showed support.
What are the key points of
the Copenhagen Accord? The accord limits global temperature increases to 2C by
2050. Scientists think it could help the world to avoid serious climate change.
The accord also says that
developed countries must promise to cut greenhouse gas emissions(排放) to the UN by 31 January, 2010. The accord asks developed countries
to give money to help developing countries.
Many countries and
organizations are disappointed that the conference didn't reach a legal
document(法律文书). And they think the accord is not clear
enough about its goals.
African leaders are
worried that the goal of a 2°C global temperature increase isn't good enough,
because it will mean a much higher increase in temperature across Africa. This
could cause big problems like food and water shortages across the continent.
Still, UN Secretary
General believes the conference was an "improvement".
"Finally we reached a
deal," Ban said," the accord may not be everything everyone had hoped
for, but this is an important beginning."
