With torrential rains and record flooding hitting the Nashville area, Tennesseans are getting a first-hand glimpse of the future due to climate change. While individual storms can be driven by a number of factors, more frequent and heavy rains are one of the impacts of climate change that people are already experiencing in many areas of the United States. “While major storms are expected this time of year in the U.S. Southeast, global warming contributes to higher air and sea temperatures that in turn promote increased moisture in the atmosphere and more intense rainfall events,” said Dr. Kevin Trenberth, Head of the Climate Analysis Division at the National Center on Atmospheric Research.  “Any resulting flooding has a direct consequence on people’s well-being and livelihood.  Unless we address the root causes of climate change, we are likely to see more of these extreme storms in our future.” The National Oceanic and Atmospheric Administration (NOAA) recently reported that the southeastern United States has witnessed a 20 percent increase in heavy precipitation from 1958-2007, which is driven by climate change.

Once again, Philadelphia faces an especially hot summer

It has been hot for days, for weeks, and for that matter, remarkably often in the last 23 years. In the period of record dating to 1874, officially eight of the 10 warmest summers in Philadelphia have occurred since 1988.

This latest heat surge continues an extraordinarily warm period that took hold in March, right after the historic snows disappeared. In New Jersey, the March 1-June 1 period - the meteorological spring - was the warmest statewide on record, said David Robinson, a Rutgers University professor who is the state climatologist.

ASTRONOMICAL SPRING FOR 2010...DEFINED AS MARCH 20 TO JUNE 20 IN THE NORTHERN HEMISPHERE...WAS THE WARMEST ON RECORD AT BOTH WASHINGTON NATIONAL DC AND WASHINGTON DULLES. AT WASHINGTON DC...THE AVERAGE SPRING TEMPERATURE OF 66.7 DEGREES BROKE THE OLD RECORD OF 66.3 DEGREES SET IN 1991. AT DULLES...THE AVERAGE SPRING TEMPERATURE OF 64.5 DEGREES BROKE THE OLD RECORD OF 63.1 DEGREES SET IN 1991. OFFICIAL CLIMATE RECORDS DATE BACK TO 1871 FOR WASHINGTON DC AND 1962 FOR DULLES.

Mumbai has over the last four years seen a gradual decline in the number of rain days, states data compiled by the disaster management department of the Brihanmumbai Municipal Corporation (BMC). While it rained on 106 days during the monsoon season in 2006, it only rained on 92 days in 2008. The number further came down to 86 in 2009.

Interestingly, however, even as the number of rain days decreased by almost 19%, for the last year when rains were deficient, the total rainfall witnessed has not deviated much.

Extreme rain events have increased due to climatic changes and global warming, a senior civic official said.

The GCC region is undergoing a heat wave that is hospitalising labourers, breaking down electricity substations and pushing power stations to the limit, experts and officials from across the region say. ¡°It¡¯s a heat wave, it¡¯s unexpected, we are having extreme temperatures for this time of year,¡± said Essa Ramadan, the senior meteorologist at the Kuwait Meteorological Department. In Kuwait, ¡°it¡¯s seven to eight degrees [Celsius] above average¡±.

The highest temperature ever recorded at Kuwait International Airport since it started taking measurements in 1957 was 51.3¢ªC in August 1998. Even though June is usually a cooler month, that temperature was matched this week. Weather stations in other areas of the country recorded temperatures as high as 54¢ªC.

Mr Ramadan blames the high temperatures on global warming, which he said is changing the Earth¡¯s weather systems and has led to an average annual rise of between 0.5¢ªC and 0.8¢ªC in Kuwait over the last 53 years. He said Kuwait, the eastern coast of Saudi Arabia, the south of Iraq and west Iran are being hit the hardest.

“Over the last 30 years, Asia has been the continent with the largest increase in frequency of weather-related disasters. Loss-relevant events have tripled in number which presents new challenges for all exposed economies.”

Alluding to the impact of climate change and its impact, Munich Re said that over the last century, the Asian continent has seen the largest temperature increase.

A storm system that stagnated over the Lower Mississippi Valley on May 1st–2nd killed 29 people and flooded thousands of homes and businesses. The storms spawned dozens of tornadoes and brought record amounts of rain to numerous locations in Mississippi, Tennessee, and Arkansas. Preliminary reports indicated that more than 200 daily, monthly, and all-time precipitation records were broken across the three states. According to the National Weather Service, Bowling Green, Kentucky set an all-time daily rainfall record for May of 4.75 inches (120 mm) on May 1st. However, that record was broken the following day as 4.92 inches (125 mm) of precipitation was recorded. The combined total of 9.67 inches (246 mm) was the greatest two-day rainfall total for the area since records began in 1870. In Nashville, the most rain ever recorded in a single calendar day fell on May 2nd—7.25 inches (184 mm)—making the precipitation received on the previous day (6.32 inches or 161 mm) the third-greatest rainfall total in Nashville's history. This led to a record two-day total of 13.53 inches (344 mm), more than doubling the previous record of 6.68 inches (170 mm) received from the remnants of Hurricane Fredrick on September 13th–14th, 1979. By just the second day of the month, Nashville had already recorded its wettest May on record and fifth wettest month ever. The torrential rains caused several rivers to crest at record levels. According to a local U.S. Geological Survey official, the flows on various rivers in the Nashville area exceeded those from the historic 1927 and 1975 floods. The Cumberland River in Nashville crested at 51.85 feet (15.80 m) on May 3rd, nearly 12 feet (3.7 m) above its flood stage—the highest level since an early 1960s flood control project was built (Source: AP). The Duck River in Centerville, Tennessee crested at 47.5 feet (14.4 m), smashing the old record of 37 feet (11.7 m) set in 1983. Fifty-two of Tennesse's 95 counties were declared disaster areas by the governor, as were 73 of Kentucky's 120 counties. Preliminary estimates placed damages at more than 1.5 billion U.S. dollars

The incidence of cardiovascular, respiratory and water-borne diseases is rising in Uruguay in tandem with climate change, while dengue fever and malaria lurk at the country's borders. Higher temperatures are encouraging the presence of insect vectors carrying diseases that were eradicated decades ago, experts say.Increasingly frequent spells of extreme weather particularly affect the health of the poorest, who live in overcrowded conditions in precarious dwellings lacking sanitation, in the shantytowns that have sprung up at an exponential rate since the 1990s in the Montevideo metropolitan area. Many of them are on low-lying land exposed to flooding. Diarrhoea, hepatitis A and leptospirosis are some of the most common illnesses resulting from flooding and inadequate disposal of human waste, the head of the Health Ministry's Environmental and Occupational Health Division, Carmen Ciganda, told IPS. "These diseases are not exactly caused by climate change, but they are associated with it and become more prevalent when there are floods or droughts," she said. At the Pereira Rossell Hospital, the country's main children's hospital, respiratory diseases climbed from 17.7 percent in 2003 to 23.3 percent in 2007, and leptospirosis cases increased from 64 in 2006 to 106 in 2007. But Ciganda warned of threats that so far have been kept at bay beyond the country's borders. "If our climate becomes more tropical, conditions will be more favourable for the vectors that transmit diseases like dengue, yellow fever and malaria," she said. The average yearly temperature in Uruguay has risen by 0.8 degrees Celsius in the last 100 years, and spring and summer average temperatures are now higher than they were in the early 20th century, while rainfall has become heavier and more frequent in the last 50 years.

"Since 2007, the mosquito has been detected in the capital city. Longer summers, and the delayed onset of cold weather (in the southern hemisphere winter) until late May, mean that the mosquitoes do not go into hibernation and continue to reproduce for a longer time," the coordinator of the Departmental Emergency Committee in Montevideo, Daniel Soria, told IPS. He said frequent heavy rainfall, a result of climate variability, hampers the struggle to prevent dengue and other diseases entering the country. "When 50 or 60 millimetres of rainwater falls in less than half an hour, it overwhelms the sewer system in Montevideo, and people in the shanty towns suffer most," he said. "Flooding of the Miguelete, Pantanoso and Carrasco rivers, which flow across the city, causes a lot of erosion, so people are constantly having to be evacuated." In Uruguay, nearly 60,000 people were evacuated between 1997 and 2008, and over half a million were affected in various ways from floods following a 30 percent increase in rainfall. The trend is expected to worsen in future, according to official reports.

AS anyone who works in a museum knows, art conservators can be slow to embrace change. But for Sarah Staniforth, director of historic properties at the National Trust in Britain, the eye opener came last September, as she contemplated photographs of a torrential downpour that had just invaded the billiard room of Cragside, one of the trust’s Victorian house museums.

Since 2000 catastrophic rainstorms have become so prevalent in England that the trust has gradually retrained its emergency teams to cope with floods, in addition to its time-honored enemy, house fires. Yet at Cragside, as with all of the trust’s 300-plus historic house museums, employees still use a standard British mid-20th-century conservation method — chiefly an electric or hot water heating system that maintains constant humidity levels — to protect irreplaceable treasures, like its painting by J. M. W. Turner and its early Burroughes & Watts billiard table.

nd now, in the photographs Ms. Staniforth viewed in her office, Cragside’s carefully tended electric conservation heating system was standing in a pool of water. So were the 19th-century fire irons and ornate wrought-iron fireplace seating unit, which had both rusted, and the billiard table, whose legs would take several months to dry out. (The room finally reopened to the public in late February.) “That photograph made me feel that we had just been fiddling while Rome burned — or, rather, flooded,” Ms. Staniforth said. “It made me see how important it is to get your priorities right, and not to worry exclusively about the humidity when your house can fill up with water as a result of climate change.”

Quebec is already seeing economic effects of climate change, said Economic Development Minister Clement Gignac. On Lac St. Jean, extremely low water levels forced sailboat owners to remove their craft from the lake, while Rio Tinto, which owns hydro dams in the area, has had to ask Hydro-Quebec for electricity."I know scientists like to be prudent, and they need proof, but there is an accumulation of meteorological anomalies in our weather -heat waves, low precipitation -that have significant economic impact," said Gignac.

Bolstered by mild winters and heavy spring rains, the poison ivy creeping across the Chicago landscape this summer is at bumper crop levels.The abundance of poison ivy and other invasive plants proliferating in Illinois and across much of the nation this year is a symptom of a scenario more serious than an itchy red rash, experts say.Elevated CO2 levels in the atmosphere, although destructive to many plant species, are proving a boon for adaptive weeds such as poison ivy, said Lewis Ziska, a federal plant physiologist.

"We are up to our arms in poison ivy this summer," said Ziska, with the USDA's Agricultural Research Service in Beltsville, Md. The higher CO2 levels, he said, also are contributing to an increasing abundance of kudzu, the legendary vine once limited to the South but was discovered lurking in central Illinois and as far north as Canada. Dr. Paul Epstein, associate director for the Center for Health and the Global Environment at Harvard Medical School, said recent studies show that poison ivy is not only more prevalent across the U.S. but more toxic, too. The rise in CO2 levels strengthens an oil in the plant that triggers itchy havoc when it touches the skin, he said. The heavy rains, warmer temperatures and rising CO2 levels that have disturbed plant chemistry also have increased pollen counts, leading to higher rates of asthma and allergies. "It's not an accident we're having this perfect storm," said Epstein. "Pests and pathogens thrive in extreme events, like floods or droughts. We need to stabilize the climate by reducing fossil fuel emissions dramatically." John Masiunas, an associate professor in the Department of Crop Sciences at the University of Illinois Urbana- Champaign, said he is unaware of any quantitative data tracking an increase in poison ivy taking root across the state. But, he said, "it makes perfect sense that higher CO2 levels will make these plants more efficient." The plant has "a survivor's ability" to grow in a variety of environments, Masiunas said, adding that climate change is also detrimental to endangered species such as native thistles and orchids that require specific soils and pollinators to thrive. "When climate change occurs … it is poor for these plants and contributes to the extinction of the species," Masiunas said. "When endangered plants are competing in an agricultural ecosystem, they start losing, and plants like poison ivy start doing better."

The nation’s heaviest rains in June poured down on Nebraska and Iowa. Records were set across both states.Iowa recorded its rainiest June in 138 years and its second-rainiest month ever, exceeded only by the rainfall of July 1993, which led to that year’s “Great Flood.”Northeastern Nebraska saw the state’s heaviest rains, with some areas recording three times the normal amount. Some places got nearly 17 inches.Near Ericson — where nearly 13 inches fell — a dam burst, draining a popular fishing lake.

Thursday Flood Risk (and the most severe 30 days in Minnesota history?)

Paul's Star Tribune Outlook for the Twin Cities and all of Minnesota

we just lived through an incredible 30-day period. According to the local National Weather Service Office in Chanhassen we experienced 395 severe storms between June 17 and July 17. That compares to 120 severe storms in all of 2009! So in a mere 30 days we saw more than 3 TIMES more severe weather than we did all of last year.

he NOAA Coral Reef Watch (CRW) Coral Bleaching Thermal Stress Outlook indicates that there is a high potential for coral bleaching in the Caribbean in 2010. The 2009-2010 El Niño ended in May 2010. However, the Caribbean typically experiences elevated temperature during the second year of an El Niño event. Since the beginning of 2010, sea surface temperatures (SSTs) in most of the Caribbean region and tropical Atlantic Ocean have been observed more than 1ºC above the normal (see the SST anomaly figure below), based on Coral Reef Watch's climatology. This pattern is similar to, but has persisted much longer than, what occurred during the same time period in 2005.

The NOAA Coral Reef Watch (CRW) Coral Bleaching Thermal Stress Outlook indicates that there is a high potential for coral bleaching in the Caribbean in 2010. The 2009-2010 El Niño ended in May 2010. However, the Caribbean usually experiences elevated temperature during the year following an El Niño event. Since the beginning of 2010, sea surface temperatures (SSTs) in most of the Caribbean region and tropical Atlantic Ocean have been observed more than 1ºC above the normal (see the SST anomaly figure above), based on Coral Reef Watch's climatology. This pattern is similar to, but has persisted much longer than, what occurred during the same time period in 2005. In 2005, a record breaking mass coral bleaching event in the Caribbean along with the most active hurricane season on record in the Atlantic Ocean followed such a pre-bleaching season SST anomaly pattern. The high SST anomaly in the Gulf of Mexico and Florida Keys began in mid-May after a dramatic increase in SST in early May (near 2ºC increase over several days at some locations) after an extreme cold outbreak earlier this year in the eastern Gulf of Mexico and Florida area. This preheating increases the likelihood that temperatures will exceed bleaching thresholds during the coming season. The pattern and intensity of early-season SST anomalies is similar to what was seen in 2005. The high potential for thermal stress above levels required to cause bleaching as seen in the CRW bleaching outlook system indicates a high potential for significant bleaching in the Caribbean region for the 2010 bleaching season. In 2005, the active hurricane season greatly reduced the coral bleaching thermal stress in the Florida Keys and Gulf of Mexico. However, the lack of tropical cyclones around the Lesser Antilles did not allow storms to relieve much the thermal stress in the epicenter of the 2005 mass bleaching event.

Low level bleaching thermal stress has already been present in the Caribbean region. The stress started to appear at the beginning of May at the eastern end of the Caribbean. It now covers most of the southern Caribbean region. In the Caribbean, bleaching-level thermal stress usually does not appear across such a wide area this early in the year. The year of 2005 was an exception and showed the similar thermal stress pattern. Given that the record breaking mass coral bleaching event occurred in 2005, the development of this year's thermal stress in the Caribbean needs to be monitored closely.

As more studies reveal findings of an increase in climate extremes in Mongolia, scientists are particularly concerned about the rapid spread of desertification caused by global warming and land degradation due to overgrazing. Presidential advisor on environmental policy, Mr. Zorigt. E, spoke recently revealed some of the most recent and alarming data about the impact of climate change across the country. Zorigt. E – Ecology and environmental policy advisor to the President of Mongolia (M): Twenty percent of all rivers have gone, according to the last count. Many other rivers and lakes are close to disappearing. Seventy-five percent of all territory has been affected by desertification. The northern part of the desertified area includes the capital city. Such an actual process already has become reality. Now we have to wake up and pay attention to it.

Speaking at the Asean Energy Business Forum Ministers-CEO Dialogue in Vietnam last Friday, Energy Secretary Jose Rene Almendras said the need to “climate-proof” the region’s energy sector was now more pressing, given the visible impact of climate change on various aspects of energy production.

He explained that the energy sector was very vulnerable to the effects of climate change, using as an example the Philippines’ experience during the extended El Niño weather phenomenon. Mindanao experienced daily rotating power interruptions, sometimes lasting 10-12 straight hours, due to severe lack of water to power the main grid’s hydropower facilities, from which the bulk of the region’s power supply came.

Apart from hydropower generation, Almendras related that wind power generation was also highly affected by climate change. “Wind power generation is susceptible to variations in ambient temperatures, humidity, and precipitation. The primary determinants of wind power availability are wind speed statistics, consisting of mean wind speeds and gustiness. Wind speeds are subject to natural variability on a wide range of time scales, and they may be affected by climate change,” he explained. To help respond to the effects of climate change, he said the country had adopted a holistic approach of combining mitigation with adaptation.

The Three Gorges dam on China's longest river, the Yangtze, is standing up to its biggest flood control test since completion last year, officials say. Floodwaters in the giant reservoir rose 4m (13ft) overnight, and are now just 20m below the dam's maximum capacity.

The flow of the water overnight was the fastest ever recorded, at 70,000 cubic metres per second. Dr Cao Guangjing, head of China Three Gorges Corporation, told the BBC that 40,000 cubic metres/second were released, with 30,000 cubic metres/second of water held back in the reservoir.

More than 35 million people across China have been affected by the poor weather and 1.2 million have been relocated. China is facing its worst floods since 1998, when more than 4,000 people died, and 18 million people were displaced, the China Daily newspaper said.

Severe and persistent drought held southern Russia in its grip in June and July 2010. Low rainfall and hot temperatures damaged 32 percent of the country’s grain crops, said Russian Agriculture Minister, Yelena Skrynnik on July 23. This satellite vegetation index image, made from data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite, shows the damage done to plants throughout southern Russia. A previously published image of land surface temperatures shows extreme heat in the drought region at the same time. The vegetation index is a reflection of photosynthesis. The index is high in areas where plants are dense, with plenty of photosynthesizing leaves. The index is low when plants are thin or not present. This image is a vegetation index anomaly image that compares photosynthesis between June 26 and July 11, 2010, to average conditions observed in late June and early July between 2000 and 2009. Below-average plant growth is shown in brown, while average growth is cream-colored. If there had been above-average growth in the region, it would have been represented in green. The land around the Volga River is brown in this image. Plants throughout the region were stressed, producing fewer leaves and photosynthesizing less between June 26 and July 11, 2010. The image is speckled brown. In the large image, which covers a broader region in more detail than the web image, the dots are clearly fields of crops. Here, the dots blend together to reveal a broad region of drought-affected crops. The Volga region is one of Russia’s primary spring wheat-growing areas. The vegetation index values shown here were the lowest late-June values seen in Russia’s spring wheat zone since the MODIS sensor began taking measurements in 2000, said an analyst from the United States Department of Agriculture (USDA) Foreign Agricultural Service. Largely as a result of the drought, the USDA expected Russia’s overall wheat crop to be 14 percent smaller than in 2009. The drought affects more than Russian farmers. Russia is the world’s fourth largest wheat exporter. If Russia isn’t able to supply as much wheat, the world’s overall wheat supply will drop. With less wheat on the market, wheat prices will go up. As of July 23, wheat futures (the current price for wheat that will be harvested and delivered in September) had risen for four consecutive weeks because of the expected drop in supply of Russian wheat, reported Bloomberg.

Provence & Cote d'Azur: 25 reported dead and fears more bodies will be found as massive clean-up operation begins in the Var After the flood Apocalyptic visions are continuing to emerge from the Var in the wake of the torrential rainfall that has been plaguing the region since Tuesday. The scenes are almost impossible to comprehend: battered cars floating down rivers that were just a few days ago normal village streets, residents surrounded by water and stranded on roofs and terraces waiting to be airlifted to safety, buildings destroyed. Most devastating of all: the death toll is rising. The number of dead now lies at 25, the majority of fatalities occurring to people travelling in vehicles. As the water starts to go down, there are fears that more bodies will be found. The situation was not helped this morning as further rain storms hit the worst affected areas, which includes Les Arcs, Draguignan, Roquebrune and Trans. The latest weather disaster to hit the region, the worst flood recorded since 1827, has already left a tragic trail of destruction and death in its wake. Among the victims; a Dutch woman in Fréjus who was swept away in a caravan being towed by her husband; a 19-year-old mechanic who was crushed inside his car in Draguignan; and an 18-month-old baby who was taken by the water from his mother's arms in Roquebrune. Damage to property has been extensive. With homes flooded and commercial buildings torn apart, normal life has come to a standstill in many places and the area resembles more a conflict zone than a popular holiday destination in the South of France. 25,000 homes were still without electricity today and schools, shops and offices remain shut. People are being strongly advised to avoid travelling in the region. The A8 may be open but many of the surrounding smaller roads have been closed and the trains continue to be severely disrupted. Yesterday, government leaders rushed to the disaster site. Brice Hortefeux, Minister of the Interior, in the Var yesterday afternoon, said that this was “an unprecedented disaster in the region.” Joining Hortefeux was Hubert Falco, France’s Secretary of State and the mayor of Toulon, the Var capital. President Sarkozy is expected to arrive in the area early next week. One million euros has been made immediately available, from national funds, for the recovery operation and more will be provided. This same sum was given to Nice and Cannes in the aftermath of the coup de mer in April and the situation this time around is seemingly far worse. It is almost incomprehensible that two “natural disasters” of this scale could occur in the region one so soon after the other. It highlighted for the second time in almost as many months how important it is to be well prepared for extreme weather conditions. As water filled and flooded streets quickly on Tuesday night, it is clear that many urban and residential areas are not designed to cope with heavy rainfall. Furthermore, it has been suggested that this kind of catastrophe can be exacerbated because a culture of risk simply does not exist in France. French senator, Bruno Retailleau, speaking at a press conference this morning, said that France must take better precautions against the risk of floods, which are the nation’s most common 'natural disaster'. He went on to say that the country has the tools to work with and the regulations in place to take preemptive measures against freak weather behaviour but that these are not used adequately. HM
