Science and techno world topic: Climate change
It is an indictment on 525 pages. Two weeks before the
summit "Rio +20" in Brazil to warn UN experts strongly that the
international environment makes little progress.
Rio de Janeiro - Experts from the United Nations has issued
the world's environmental policy a damning testimony. The United Nations
Environment Program (UNEP) warns in his new report, "Geo-5”,
one-third of 90 major environmental goals have been achieved over the past five
years, no progress. At 40 there was some improvement.

less ozone-damaging gas in the atmosphere ,

The bad news is however, far more numerous, so warn the
authors of the study of a collapse of ecosystems. "This is an
indictment," the UNEP chief Achim Steiner said at a press conference in
Rio de Janeiro. "We live in an age of irresponsibility, which is
documented in this report." A change is possible, however. Steiner
called for urgent measures to stop the exploitation of the environment.
"While the human pressure on the earth, there are
several critical global, regional and local limits already reached or
exceeded," says the report. "If they are exceeded, it is likely
to be abrupt and potentially irreversible changes in the life-sustaining
functions of the planet."
At 525 pages, the experts draw a gloomy picture of the
organization of our planet. Such a threatened including the melting of polar
ice caps, the spread of deserts in Africa and the deforestation of
tropical forests to life on Earth. Already, 20 percent of vertebrates
are threatened with extinction, the coral reefs had shrunk by 38
percent since 1980, and greenhouse gas emissions could double in the next 50
years.
"Will see if the trend continues like this and the
behavior of production and consumption of natural resources can not be
reversed, then the government an unprecedented dimension of damages and
losses," Steiner warned.
In just over two weeks there in Brazil, the United Nations
Earth Summit "Rio+20" instead. The name commemorates the UN
Earth Summit in 1992.Developed from this meeting, including the Climate Change
Convention and later the Kyoto Protocol and the Convention on
Biological Diversity.
So far could the industrialized countries and developing
countries can not agree, however, about the goals of the "Rio +20". UN
Secretary General Ban Ki Moon acknowledged that negotiations on a final
document be difficult. He was, however, is "cautiously
optimistic" that the 193 UN members could agree on an agreement.
Environmental organizations such as WWF warned however
against a failure. There were two likely scenarios, WWF Director General Jim
Leape said the "Guardian": either adopted the conference was a soft
diaper and empty document - or they fail altogether.
