WMO Bulletin highlights growth in nitrous oxide in atmosphere
The amount of greenhouse gases in the atmosphere reached a new high in 2010 since pre-industrial time and the rate of increase has accelerated, according to the World Meteorological Organization’s Greenhouse Gas Bulletin. It focussed special attention on rising nitrous oxide concentrations.
Between 1990 and 2010, according to the report, there was a 29% increase in radiative forcing - the warming effect on our climate system - from greenhouse gases. Carbon dioxide accounted for 80% of this increase.
IPCC releases special report on extreme events
The Summary for Policymakers of the Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX) was approved today by member governments of the Intergovernmental Panel on Climate Change (IPCC), which is co-sponsored by WMO.
Rajendra Pachauri, Chair of the IPCC, said: "This summary for policymakers provides insights into how disaster risk management and adaptation may assist vulnerable communities to better cope with a changing climate in a world of inequalities".
"It also underlines the complexity and the diversity of factors that are shaping human vulnerability to extremes--why for some communities and countries these can become disasters whereas for others they can be less severe," he added. The report said there is “high confidence that both maximum and minimum daily temperatures have increased on a global scale due to the increase of greenhouse gases.”
La Niña conditions have re-emerged in the tropical Pacific since August 2011, according to the latest Update from the World Meteorological Organization. This La Niña is expected to persist through the end of this year and into early 2012, possibly strengthening to moderate intensity. However, it is likely to be considerably weaker than the recent episode that was linked to flooding and drought in different parts of the world.
The Update is based on input from climate prediction centres and experts around the world and is an authoritative source of information on a phenomenon which has such a widespread impact on weather and climate – and lives and livelihoods – around the globe.
An International Conference on Adaptation to Climate Change and Food Security in West Asia and North Africa today adopted the “Kuwait Declaration” which called for urgent actions to minimize the region’s short and long-term vulnerability to climate change.
The declaration was adopted by more than 80 participants from 18 countries and nine international and regional organizations who attended the four day conference in Kuwait City.
Agriculture is the primary source of livelihoods and revenue for the majority of the population in many countries in West Asia and North Africa and over 70% of the region’s poor live in rural areas. Cereal yields are currently only half the world average and all countries in the region are net importers of food. Over 70% of the land area is rangelands and traditional livestock provide the major support for livelihoods. Population growth is straining natural resources. Expansion of cultivated land and livestock numbers and a decrease in forests is leading to land degradation and desertification.
