Leaders from 32 nations that are part of the major tropical forests in Africa, Asia and Latin America will meet for the first time to promote co-operation on issues that have become increasingly important to preserving forests and preventing climate change.

Henri Djombo, minister of sustainable development, forestry and environment for the Republic of Congo, told a news conference Wednesday that his country will host the summit from May 31-June 3 in the capital Brazzaville.

REUTERS/Alexander NatruskinBANGKOK (AlertNet) – As climate negotiators talk this week in Bangkok, there are no signs the gap between the amount of emissions countries have pledged to cut and what is needed to avoid temperatures rising to dangerous levels has been bridged, climate experts said.

Scientists say the world needs to keep global temperature increases to below 2 degrees Celsius above pre-industrial levels to avoid dangerous climate change, including impacts like more extreme weather and rising sea level.

To achieve this, current global emissions of greenhouse gases, blamed for global warming, need to drop to 40 to 44 billion tonnes, according to the Climate Action Tracker, an assessment tool set up by three European organisations to track emission commitments and actions of countries.

But emissions reductions proposals by governments so far have been inadequate, data show.

Geneva, 5 April 2011 GENEVA 5 APRIL 2011 (WMO) — Depletion of the ozone layer- the shield that protects life on Earth from harmful levels of ultraviolet rays - has reached an unprecedented level over the Arctic this spring because of the continuing presence of ozone-depleting substances in the atmosphere and a very cold winter in the stratosphere. The stratosphere is the second major layer of the Earth’s atmosphere, just above the troposphere.

The record loss is despite an international agreement which has been very successful in cutting production and consumption of ozone destroying chemicals. Because of the long atmospheric lifetimes of these compounds it will take several decades before their concentrations are back down to pre-1980 levels, the target agreed in the Montreal Protocol on Substances that Deplete the Ozone Layer.
