GENEVA – Much of the extreme weather that wreaked havoc in Asia, Europe and the Pacific region last year can be blamed on human-induced climate change, the U.N. weather agency says.

The World Meteorological Organization's annual assessment Monday said 2013 was the sixth-warmest year on record. Thirteen of the 14 warmest years have occurred in the 21st century.

A rise in sea levels is leading to increasing damage from storm surges and coastal flooding, as demonstrated by Typhoon Haiyan, the agency's Secretary-General Michel Jarraud said. The typhoon in November killed at least 6,100 people and caused $13 billion in damage to the Philippines and Vietnam.

Australia, meanwhile, had its hottest year on record.
"Many of the extreme events of 2013 were consistent with what we would expect as a result of human-induced climate change," Jarraud said.

He also cited other costly weather disasters such as $22 billion damage from central European flooding in June, $10 billion in damage from Typhoon Fitow in China and Japan, and a $10 billion drought in much of China.

Only a few places -- including the central U.S. --were cooler than normal last year, but 2013 had no El Nino, the warming of the central Pacific that happens once every few years and changes rain and temperature patterns around the world.

Jarraud spoke as top climate scientists and representatives from about 100 governments with the U.N.'s Intergovernmental Panel on Climate Change met in Japan to complete their latest report on global warming's impact on hunger, disease, drought, flooding, refugees and war.

Speaking in Geneva, Jarraud drew special attention to studies and climate modeling examining Australia's recent heat waves, saying the high temperatures there would have been virtually impossible without the emissions of heat-trapping carbon dioxide from the burning of coal, oil and gas.

"It is not possible to reproduce these heat waves in the models if you don't take into account human influence," he said.

To state the obvious, the weather around the globe keeps getting more and more intense everywhere. It is getting much colder in some regions and much hotter in others. It is global warming and it is global cooling . . .

Centuries of warming locked into earth’s climate warns UN

Record temperatures, heavy monsoon rains and rising sea levels are all signs the climate is changing, says the UN’s World Meteorological Organization.

Its 2013 State of the Climate report, published annually, says last year tied with 2007 as the sixth warmest on record, continuing what it says is a “long term warming trend”. 13 of the 14 warmest years on record occurred since the year 2000, it adds.

In a statement WMO Secretary-General Michel Jarraud said record levels of greenhouse gases would mean the atmosphere and oceans will warm for centuries to come.

“There is no standstill in global warming,” he said, referring to a 15-year hiatus in land temperatures. “The warming of our oceans has accelerated, and at lower depths.

“More than 90% of excess energy trapped by greenhouse gases is stored in the oceans,” he said, adding: “the laws of physics are non-negotiable.”
The WMO says the global average surface temperature was 0.5C ± 0.1C above the 1961–1990 average and 0.03C above the 2001–2010 average.

In the past 12 months Australia experienced its hottest year on record, with Argentina registering its second warmest.

A study by scientists at the University of Melbourne cited by the WMO by concluded Australia’s record summer was five times as likely as a result of man made climate change.

Jarraud said the surge in storms also demonstrates the need for further investment in forecasting systems and better resilience to further reduce losses of life.

“We must continue to strengthen preparedness and early warning systems and implement a multi-hazard approach to disaster risk reduction,” he said.

This week UN scientists working on the next instalment of the IPCC’s climate science review meet in Yokohoma, Japan to discuss the scale of future impacts from climate change.

Leaks online indicate the report will warn of ever more dangerous impacts without rapid action to curb carbon emissions, including extreme weather, sea level rise and species extinctions.

“Risks to the overall global economy and Earth’s biodiversity become moderate for warming between 1-2 degrees Celsius and high around 3 degrees (above levels at the start of this century),” one draft says.

“With or without adaptation climate change will reduce median (crop) yields by 0 to 2% per decade for the rest of this century as compared to a baseline without climate change.”

Scientists meet in Japan after grim climate forecast

(AFP) – 1 hour ago

Yokohama — International scientists will gather near Tokyo on Tuesday for a week-long meeting centred on a grim climate change report that warned of floods and drought that would stoke conflicts and wreak havoc on the global economy.

A draft of their report, seen by AFP, is part of a massive overview by the Intergovernmental Panel on Climate Change (IPCC), likely to shape policies and climate talks for years to come.

Scientists and government representatives are meeting in Yokohama, south of Tokyo, from Tuesday to exchange ideas and release a full report at the end of the conference on March 31.

"We have a lot clearer picture of impacts and their consequences... including the implications for security," said Chris Field of the United States' Carnegie Institution, who headed the probe.

The work comes six months after the first volume in the long-awaited Fifth Assessment Report declared scientists were more certain than ever that humans caused global warming.

Rising greenhouse-gas emissions will "significantly" boost the risk of floods, with Europe and Asia particularly exposed, the draft says.

Temperature increase was also leading to decline of renewable water resources, while the rising sea level was seen to displace "hundreds of millions" of coastal dwellers by 2100, according to the draft report.

Average yields of wheat, rice and corn were seen to fall, while demand for crops will likely rise sharply due to expanding population.

Poverty, migration and hunger are invisible drivers of turbulence and war, as they sharpen competition for dwindling resources, the report warns.

By reducing carbon emissions "over the next few decades", the world can stave off many of the worst climate consequences by century's end, says the report.

The panel has issued four previous "assessment reports" in its quarter-century history.

The Yokohama volume goes further than its predecessors in forecasting regional impacts in greater detail and emphasising the risk of conflict and rising seas.

The IPCC's last big report in 2007 helped unleash political momentum leading to the 2009 UN climate summit in Copenhagen. But its reputation was dented by several mistakes, seized upon by climate skeptics as proof of bias.

Geneva - There has been no reverse in the trend of global warming and there is still consistent evidence for man-made climate change, the head of the UN World Meteorological Organisation (WMO) said on Monday.

A slowdown in the average pace of warming at the planet's surface this century has been cited by "climate sceptics" as evidence that climate change is not happening at the potentially catastrophic rate predicted by a UN panel of scientists.

But UN weather agency chief Michel Jarraud said ocean temperatures, in particular, were rising fast, and extreme weather events, forecast by climate scientists, showed climate change was inevitable for the coming centuries.

"There is no standstill in global warming," Jarraud said as he presented the WMO's annual review of the world's climate which concluded that 2013 tied with 2007 as the sixth hottest year since 1850 when recording of annual figures began.

"The warming of our oceans has accelerated, and at lower depths. More than 90% of the excess energy trapped by greenhouse gases is stored in the oceans.

Future

"Levels of these greenhouse gases are at a record, meaning that our atmosphere and oceans will continue to warm for centuries to come. The laws of physics are non-negotiable," Jarraud told a news conference.

The 21-page survey said the global land and sea surface temperature in 2013 was 14.5°C, or 0.50°C above the 1961 - 90 average. It was also 0.03°C up on the average for 2001 - 2010.

The WMO's Annual Statement on the Status of the Climate, pointed to droughts, heat waves, rising seas, floods and tropical cyclones around the globe last year as evidence of what the future might hold.

It was issued on the eve of a conference bringing climate scientists together with officials from over 100 governments in Japan from 25 - 29 March to approve a report on the effects of future global warming and how these might be mitigated.

A draft of this report, from the Intergovernmental Panel on Climate Change (IPCC), says global warming will disrupt food supplies, slow world economic growth and may already be causing irreversible damage to nature.

The chair of the IPCC, Rajendra Pachauri, said that the report made even more compelling the scientific arguments for a reduction in greenhouse gas emissions.

Some 200 countries have agreed to try to limit global warming to less than 2°C above pre-industrial times, largely by cutting emissions from burning fossil fuels like coal, oil and gas.

Sceptics

Sceptics argue that changes in global weather are the product of natural fluctuations or other natural causes.

But such arguments were rejected by Jarraud.

Natural phenomena like volcanoes or the El Niño or La Niña weather patterns originating in Pacific Ocean temperature changes had always framed the planet's climate, affecting heat levels and disasters like drought and floods, he said.

"But many of the extreme events of 2013 were consistent with what we would expect as a result of human-induced climate change," declared the WMO chief, pointing to the destruction wreaked by Typhoon Haiyan in the Philippines.

Another example was the record hot summer of 2012 - 13 in Australia which brought huge bush fires and destruction of property. Computer simulations showed the heat wave was five times as likely under human influence on climate, Jarraud said.

Among other extreme events of 2013 probably due to climate change were winter freezes in the US south-east and Europe, heavy rains and floods in north-east China and eastern Russia, snow across the Middle East and drought in south-east Africa.
