New study quantifies the effects of climate change in Europe

eu flag 1

JRC: If no further action is taken and global temperature increases by 3.5°C, climate damages in the EU could amount to at least €190 billion, a net welfare loss of 1.8% of its current GDP. Several weather-related extremes could roughly double their average frequency. As a consequence, heat-related deaths could reach about 200 000.

The cost of river flood damages could exceed €10 billion and 8000 km2 of forest could burn in southern Europe. The number of people affected by droughts could increase by a factor of seven and coastal damage, due to sea-level rise, could more than triple

More, bigger wildfires burning western U.S.

AGU: Wildfires across the western United States have been getting bigger and more frequent over the last 30 years – a trend that could continue as climate change causes temperatures to rise and drought to become more severe in the coming decades, according to new research.  The number of wildfires over 1,000 acres in size in the region stretching from Nebraska to California increased by a rate of seven fires a year from 1984 to 2011, according to a new study accepted for publication in Geophysical Research Letters, a journal published by the American Geophysical Union. The total area these fires burned increased at a rate of nearly 90,000 acres a year – an area the size of Las Vegas, according to the study. Individually, the largest wildfires grew at a rate of 350 acres a year, the new research says.

Middle East drought a threat to global food prices

AlertNet: The Middle East’s driest winter in several decades could pose a threat to global food prices, with local crops depleted and farmers’ livelihoods blighted, U.N. experts and climatologists say.  Varying degrees of drought are hitting almost two thirds of the limited arable land across Syria, Lebanon, Jordan, the Palestinian territories and Iraq.

“Going back to the last 100 years, I don’t think you can get a five-year span that’s been as dry,” said Mohammad Raafi Hossain, a U.N. Food and Agriculture Organisation (FAO) environmental economist.  The dry season has already hurt prospects for the cereal harvest in areas of Syria and to a lesser extent Iraq. Several of the countries under pressure are already significant buyers of grain from international markets.

Heatwaves: Hotter, Longer, More Often

aus climate council heatwaves

AUS Climate Couincil: The report examines the impact of climate change on heatwaves and hot weather in Australia and around the world.

FIVE TOP FACTS  :

Climate change is already increasing the intensity and frequency of heatwaves in Australia. Heatwaves are becoming hotter, lasting longer and occurring more often.

Climate change is making heatwaves worse in terms of their impacts on people, property, communities and the environment. Heatwaves have widespread impacts, ranging from direct impacts on our health to damage to ecosystems, agriculture and infrastructure.

The climate system has shifted, and is continuing to shift, increasing the likelihood of more extreme hot weather.

Record hot days and heatwaves are expected to increase in the future

Limiting the increase in heatwave activity requires urgent and deep reductions in the emissions of greenhouse gases.

Scientists find precipitation, global warming link

The rain in Spain may lie mainly on the plain, but the location and intensity of that rain is changing not only in Spain but around the globe.

A new study by Lawrence Livermore National Laboratory scientists shows that observed changes in global (ocean and land) precipitation are directly affected by human activities and cannot be explained by natural variability alone. The research appears in the Nov. 11 online edition of the Proceedings of the National Academy of Sciences.

Emissions of heat-trapping and ozone-depleting gases affect the distribution of precipitation through two mechanisms. Increasing temperatures are expected to make wet regions wetter and dry regions drier (thermodynamic changes); and changes in atmospheric circulation patterns will push storm tracks and subtropical dry zones toward the poles.

More than 500 million people might face increasing water scarcity

pik savana

Both freshwater availability for many millions of people and the stability of ecosystems such as the Siberian tundra or Indian grasslands are put at risk by climate change. Even if global warming is limited to 2 degrees above pre-industrial levels, 500 million people could be subject to increased water scarcity – while this number would grow by a further 50 percent if greenhouse-gas emissions are not cut soon. At 5 degrees global warming almost all ice-free land might be affected by ecosystem change. This is shown by complementary studies now published by scientists of the Potsdam Institute for Climate Impact Research (PIK).

NOAA: Human influences are having an impact on some extreme weather and climate events, according to the report Explaining Extreme Events of 2012 from a Climate Perspective released September 5, 2013 by the Bulletin of the American Meteorological Society. Scientists from NOAA served as three of the four lead editors on the report. Overall, 18 different research teams from around the world contributed to the peer-reviewed report that examined the causes of 12 extreme events that occurred on five continents and in the Arctic.

The report shows that the effects of natural weather and climate fluctuations played a key role in the intensity and evolution of many of the 2012 extreme events. However, in several events, the analyses revealed compelling evidence that human-caused climate change was a secondary factor contributing to the extreme event. “This report adds to a growing ability of climate science to untangle the complexities of understanding natural and human-induced factors contributing to specific extreme weather and climate events,” said Thomas R. Karl, LHD, director of NCDC. “Nonetheless, determining the causes of extreme events remains challenging.” read more

Heat Waves to Become Much More Frequent and Severe

IOP: Climate change is set to trigger more frequent and severe heat waves in the next 30 years regardless of the amount of carbon dioxide (CO2) we emit into the atmosphere, a new study has shown. Extreme heat waves such as those that hit the US in 2012 and Australia in 2009 – dubbed three-sigma events by the researchers – are projected to cover double the amount of global land by 2020 and quadruple by 2040.  Meanwhile, more-severe summer heat waves – classified as five-sigma events – will go from being essentially absent in the present day to covering around three per cent of the global land surface by 2040.  The new study, which has been published , Thursday 15 August, in IOP Publishing’s journal Environmental Research Letters, finds that in the first half of the 21st century, these projections will occur regardless of the amount of CO2 emitted into the atmosphere.

Sahel: Recurrent Climate Shocks Propel Migration

Refugees International: Recurrent climate-related shocks in West Africa’s Sahel region are having severe impacts on vulnerable populations. Increasingly, those unable to feed themselves or their families have no option but to leave their villages, resorting to new forms of migration that bring with them serious protection risks.

Although the Sahel region is prone to droughts, over the past decade, marked changes in rainfall patterns have emerged. Rains have become more erratic in terms of quantity, timing, and geographic scope, making droughts and poor harvests more frequent. These changes are, in turn, having enormous impacts on the region’s livestock herders (pastoralists) and farmers who rely on crops to feed their animals (agro-pastoralists), given their dependence on rainfall for their livelihoods. This is especially the case for agro-pastoralists, for whom proper forecasting of the timing, location, and quantity of precipitation is crucial for planting. read more

Timeline: extreme weather and climate-related events in 2013

timeline rtcc

The World Resources Institute have compiled a useful timeline chronicling extreme weather events in 2012 and 2013.

The pattern for extreme events that we saw in 2012 continued into 2013. In early 2013, parts of the Southern Hemisphere witnessed record-high temperatures, with Australia experiencing its hottest month in January 2013 since record-keeping began more than a century ago. Meanwhile, the central and northeastern United States saw record snowfall and blizzard conditions. Precipitation continued to be extreme throughout the spring, with Spain seeing its wettest March on record and China experiencing its wettest May since 1973. At the same time, New Zealand saw its worst drought in three decades, and California experienced its driest year-to-date

Water in the Anthropocene is a 3-minute film charting the global impact of humans on the water cycle.  Evidence is growing that our global footprint is now so significant we have driven Earth into a new geological epoch — the Anthropocene.

Human activities such as damming and agriculture are changing the global water cycle in significant ways.

The data visualisation was commissioned by the Global Water Systems Project for a major international conference (Water in the Anthropocene, Bonn, Germany, 21-24 May, 2013).

As datasets build upon one another, the film charts Earth’s changing global water cycle, why it is changing, and what this means for the future. The vertical spikes that appear in the film represent the 48,000 large dams that have been built.

China: High and dry

The Financial Times: Water shortages put a brake on economic growth

In the face of China’s rapid economic expansion and growing presence on the global stage, it is often forgotten that the country is running out of water. In per capita terms, China’s water resources are just a quarter of the world average. Eight of China’s 28 provinces are as parched as countries in the Middle East such as Jordan and Syria, according to China Water Risk, a consultancy based in Hong Kong.

Australia: The hottest summer on record

Bureau of Meteorology: This summer hasn’t just felt hot. It’s been hot. The numbers are in, and the Bureau has confirmed this summer has been Australia’s hottest on record.  Average temperatures across the country came in at 28.6°C, 1.1°C above normal, and exceeding the previous record set in the summer of 1997-98 by more than 0.1°C. A new daytime maximum temperature record was also set at 35.7°C, or 1.4°C above normal, and 0.2°C above the 1982/83 record.  The most extreme heat occurred in the first three weeks of January during an exceptionally widespread and prolonged heatwave. The highest temperature recorded during the heatwave was at Moomba in South Australia at 49.6°C.

Of the 112 locations used in long-term climate monitoring, 14 had their hottest day on record during the summer of 2012/13 – the largest number in any single summer. Record temperatures were also set in two capital cities; Sydney with 45.8°C and Hobart with 41.8°C.

A new record was also set for the number of consecutive days the average maximum daily temperature for Australia exceeded 39°C – seven days between 2 and 8 January 2013, almost doubling the previous record of four consecutive days in 1973. More

Increases in extreme rainfall linked to global warming

The University of Adelaide: A worldwide review of global rainfall data led by the University of Adelaide has found that the intensity of the most extreme rainfall events is increasing across the globe as temperatures rise.  In the most comprehensive review of changes to extreme rainfall ever undertaken, researchers evaluated the association between extreme rainfall and atmospheric temperatures at more than 8000 weather gauging stations around the world.  Lead author Dr Seth Westra said, “The results are that rainfall extremes are increasing on average globally. They show that there is a 7% increase in extreme rainfall intensity for every degree increase in global atmospheric temperature.  “Assuming an increase in global average temperature by 3 to 5 degrees Celsius by the end of the 21st century, this could mean very substantial increases in rainfall intensity as a result of climate change.” More

Global warming from greenhouse gases affects rainfall patterns in the world differently than that from solar heating, according to a study by an international team of scientists in the January 31 issue of Nature. Using computer model simulations, the scientists, led by Jian Liu (Chinese Academy of Sciences) and Bin Wang (International Pacific Research Center, University of Hawaii at Manoa), showed that global rainfall has increased less over the present-day warming period than during the Medieval Warm Period, even though temperatures are higher today than they were then.

Andean glacier melt threatens floods, then drought

AlertNet : As glaciers melt in the Andes, western areas of South America can expect a period of repeated, extreme flooding that will later give way to drought conditions, creating new challenges for millions of people, researchers warn.  Tropical Andean glaciers and high-altitude ecosystems are vital to the economies of Peru, Ecuador, Colombia and Bolivia. The 8 million inhabitants of Peru’s capital Lima depend on them for drinking water. The Bolivian capital, La Paz, takes 30 to 40 percent of its drinking water from glaciers in the Cordillera Real.  Glacial water powers hydro-electric generation and feeds agriculture in all four countries, while supporting biodiversity in the high Andes.

When national disasters go global

AlertNet: The national Drought Monitor recently declared a drought for almost 80 percent of the contiguous United States, ranging in intensity from “abnormally dry” to “drought-exceptional.”  Five days ago, the U.S. Department of Agriculture followed by declaring disasters in 26 U.S. states. This is the largest national disaster area ever declared.

But while the drought is obviously a serious concern for the U.S. (historically, droughts are the nation’s most costly natural disaster), it also has worrying implications for other countries that are tied to the U.S. through the global food market. Coupled with other recent extreme weather events across the globe, the U.S. drought could have a globally destabilizing influence.  And while it is too early to tell exactly why these events are happening, recent reports show that climatic changes are a part of the story.

Climate Change Has Intensified the Global Water Cycle

ClimateCentral: Climate scientists have been saying for years that one of the many downsides of a warming planet is that both droughts and torrential rains are both likely to get worse. That’s what climate models predict, and that’s what observers have noted, most recently in the IPCC’s report on extreme weather, released last month. It makes physical sense, too. A warmer atmosphere can absorb more water vapor, and what goes up must come down — and thanks to prevailing winds, it won’t come down in the same place.

The idea of changes to the so-called hydrologic cycle, in short, hangs together pretty well. According to a new paper just published in Science, however, the picture is flawed in one important and disturbing way. Based on measurements gathered around the world from 1950-2000, a team of researchers from Australia and the U.S. has concluded that the hydrologic cycle is indeed changing. Wet areas are getting wetter and dry areas are getting drier. But it’s happening about twice as fast as anyone thought, and that could mean big trouble for places like Australia, which has already been experiencing crushing drought in recent years. Continue

Syria: Climate Change, Drought and Social Unrest

Syria- Climate Change, Drought and Social Unrest - ThinkProgress 2012-03-05 16-33-45

Climate Progress:

NOAA concluded in 2011 that “human-caused climate change [is now] a major factor in more frequent Mediterranean droughts.” Reds and oranges highlight lands around the Mediterranean that experienced significantly drier winters during 1971-2010 than the comparison period of 1902-2010.

Syria’s current social unrest is, in the most direct sense, a reaction to a brutal and out-of-touch regime and a response to the political wave of change that began in Tunisia early last year. However, that’s not the whole story. The past few years have seen a number of significant social, economic, environmental and climatic changes in Syria that have eroded the social contract between citizen and government in the country, have strengthened the case for the opposition movement, and irreparably damaged the legitimacy of the al-Assad regime. If the international community, and future policy-makers in Syria, are to address and resolve the drivers of unrest in the country, these changes will have to be better explored and exposed.

The CCAPS program released the pilot version of its dynamic mapping tool today. In partnership with AidData, CCAPS developed the online data portal to enable researchers and policymakers to visualize data on climate change vulnerability, conflict, and aid, and to analyze how these issues intersect in Africa.

The mapping tool, which uses Esri technology, allows users to select and layer any combination of CCAPS data onto one map to assess how myriad climate change impacts and responses intersect. For example, mapping conflict data over climate vulnerability data can assess how local conflict patterns could exacerbate climate-induced insecurity in a region. It also shows how conflict dynamics are changing over time and space. Continue

Threat of malnutrition dire in Africa’s Sahel region due to increasing food shortages

unicef

UNICEF: It’s not a tsunami or an earthquake – it is a predictable emergency. UNICEF estimates more than a million children under five will need to be treated in feeding centres for severe malnutrition in the Sahel region of Africa. It is a staggeringly high number, and there is little time to prepare.

Extreme food insecurity

The situation is extremely dire for children in many parts of the Sahel region of West and Central Africa. Due to poor rains and the resulting restricted harvests, entire populations are now vulnerable. In surveys carried out over the summer and autumn by UNICEF nutrition teams, seven of the eight countries showed pockets with elevated rates of global malnutrition for children under five. The driest parts of Chad and Mauritania had levels that put them into the category that requires an emergency response.

With an estimated 330,600 children under age five at risk of severe and acute malnutrition in Niger, the government has issued an alert saying more than half of the country’s villages are vulnerable to food insecurity. Other countries and regions where children are expected to require specialist treatment in clinics are northern Nigeria, the north of Cameroon, Burkina Faso, Mali and northern Senegal. Continue
