The study, which looked at the number of very hot days in 53 U.S. metro area between 1956 and 2005, says the number of very hot days is on the rise globally, but the rate of increase is more than double in the most sprawling regions compared with more compact cities. This was true regardless of the urban regions’ climate zone, population size or rate of growth. The annual number of very hot days increased by 14.8 days on average in the regions with the most sprawl and by 5.6 days in the least sprawling cities, according to the study.

Between 1992 and 2001, the rate of deforestation in the most sprawling regions was more than double that of compact regions, the study noted. Other studies have shown that the loss of vegetative cover is one of the main reasons that cities become much hotter than surrounding areas.

Oklahoma City's rainiest day in history brought rampaging floods to the city and surrounding areas yesterday, as widespread rain amounts of 8 - 11 inches deluged the city. Fortunately, no confirmed deaths or injuries have been blamed on the mayhem, though damage is extensive. Oklahoma City's Will Rogers Airport received 7.62" of rain yesterday, smashing the record for the rainiest day in city history. According to the National Climatic Data Center, the city's previous rainiest day occurred September 22, 1970, when 7.53 inches fell. Some rivers continue to rise due to all the rain, and the Canadian River east of downtown Oklahoma City is four feet over flood stage, with major flooding expected today.

CoreLogic® Finds More Than $234 Billion in Residential Storm Surge Exposure in 13 U.S. Cities

Sizzling Moscow shrouded in polluting smog

A cloud of harmful smog has enveloped Moscow, raising airborne pollutants to four times the norm, officials said Wednesday, and prompting doctors to urge residents to stay indoors as the city swelters in a record heat wave.

A heat wave has hit central Russia breaking temperature records going higher than 30 C (86 F) for four weeks breaking all records for the last 130 years and smoke from burning forests around Moscow has reached the city.

Killer heat hits Korea, little relief this month

The temperature in South Jeolla hit highs of 34 degrees Celsius (93 degrees Fahrenheit) at the start of the month.

“We are considering announcing the number of heat fatalities on a weekly basis,” said an official at the Health Ministry, “to inform the public of the danger outside.”According to ministry records, 24 people rushed to emergency rooms on Aug. 2 and 3 had no other health problems. Another 16 who went to the hospital had conditions that were made worse by the heat.

China issued a fresh heatwave alert Wednesday as soaring temperatures -- some of them record highs -- were again forecast for large swathes of the nation, sparking concerns about power shortages.The National Meteorological Centre warned that large parts of northern and central China would again be hit by "sweltering heat and very little rain", with temperatures set to hit 40 degrees Celsius (104 degrees Fahrenheit).It set the heat alert at "orange" -- the second-highest rating on a four-colour scale.The extreme heat, which began at the weekend in most areas, has led to hospital wards packed with people suffering from heat-related illnesses, a surge in air-conditioner sales and even a plague of locusts in Inner Mongolia.

used giant ice blocks to keep animals cool, the Xinhua news agency reported.In several cities including Beijing, where the temperature hit 40.6 degrees Celsius on Monday, authorities reported that overheated vehicles had caught fire, state media said.The heatwave comes after torrential rains in June, mainly in southern parts of the nation, caused massive floods and landslides that killed at least 266 people.The soaring temperatures have led to fears of power shortages in several provinces due to high demand for air conditioning, the state-run Global Times reported.In the southern city of Guangzhou, authorities had opened nearly 500 shelters equipped with air-conditioning units and water for people to escape the heat, the report said.Water demand has also soared along with the high temperatures.In Beijing on Monday, nearly three million cubic metres of water was pumped into the capital, the largest single-day usage since tap water was brought into operation in 1910, the China Daily reported.Authorities in the capital said they would double a "high temperature" subsidy for people working outside in the heat, or whose workplaces were hotter than 33 degrees Celsius.Those who work outside will now get an extra 120 yuan (18 dollars) a month, while people in hot indoor places will be paid 90 yuan, the report said.

Four days after rainstorms pummeled my hometown, problems mount. Major portions of the city are still submerged beneath floodwaters. Thousands are displaced from their homes, the contents of their lives soaked, mud-caked and molding. Thousands more have no electricity or plumbing. The city faces severe drinking water shortages, with several water treatment facilities paralyzed.

in the coming months, as Nashvillians reflect on this shock, we may conclude that we've gotten a firsthand glimpse of the symptoms of a warming planet.

the unprecedented intensity of this storm -- which produced the largest volume of rainfall from a single storm on record in the state of Tennessee -- is closely tied to warming climate trends.

Extreme heat wave sets all-time high temperature records in Africa and Middle EastA withering heat wave of unprecedented intensity and areal covered has smashed all-time high temperatures in four nations in the Middle East and Africa over the past week. Saudi Arabia, Iraq, Chad, and Niger all set new records for their hottest temperatures of all time, and several other Middle East nations came within a degree of their hottest temperatures ever. The heat was the most intense in Iraq, which had its hottest day in history on June 14, 2010, when the mercury hit 52.0°C (125.6°F) in Basra. Iraq's previous record was 51.7°C (125.1°F) set August 8, 1937, in Ash Shu'aybah. It was also incredibly hot in Saudi Arabia, which had its hottest temperature ever on Tuesday (June 22): 52.0°C (125.6°F), measured in Jeddah, the second largest city in Saudi Arabia. The previous record was 51.7°C (125.1°F), at Abqaiq, date unknown. The record heat was accompanied by a sandstorm, which caused eight power plants to go offline, resulting in blackouts to several Saudi cities.In Africa, Chad had its hottest day in history on Tuesday (June 22), when the temperature reached 47.6°C (117.7°F) at Faya. The previous record was 47.4°C (117.3°F) at Faya on June 3 and June 9, 1961. Niger tied its record for hottest day in history on Tuesday (June 22), when the temperature reached 47.1°C (116.8°F) at Bilma. That record stood for just one day, as Bilma broke the record again on Wednesday (June 23), when the mercury topped out at 48.2°C (118.8°F). The previous record was 47.1°C on May 24, 1998, also at Bilma.Three countries came within a degree of their all time hottest temperature on record during the heat wave. Bahrain had its hottest June temperature ever, 46.9°C, on June 20, missing the all-time record of 47.5°C (117.5°F), set July 14, 2000. Temperatures in Quatar reached 48.8°C (119.8°F) on June 20. Quatar's all-time record hottest temperature was 49.6°C (121.3°F) set on July 9, 2000. It was also very hot in Kuwait, with temperatures reaching 51°C (123.8°F) in the capital on June 15. Kuwait's all-time hottest temperature was 51.9°C (125.4°F), on July 27,2007, at Abdaly. According to Essa Ramadan, a Kuwaiti meteorologist from Civil Aviation, Matrabah, Kuwait smashed this record and had Asia's hottest temperature in history on June 15 this year, when the mercury hit 54.0°C (129.2°F). However, data from this station is notoriously bad, and each year bogus record highs have to be corrected, according to an email I received from weather record researcher Maximiliano Herrera. Asia's hottest temperature in history will very likely remain the 53.5°C (128.3°F) recorded at MohenjuDaro, Pakistan on May 26 this year.

Still recovering from a 10-year drought on the world's driest inhabited continent, Australia is increasingly turning to the oceans that surround it for drinking water. Australia's five largest cities have embarked on a massive $13-billion plan to build desalination plants that can remove the salt from seawater and make it potable. By 2012, when the last plant is scheduled to be up and running, Australia's big cities will get 30% of their water from the oceans, The New York Times reported Sunday. The government says Australia's latest decade-long drought was largely caused by climate change and one official called the $13-billion desalination programme "the cost of adapting to climate change."

"We consider ourselves the canary in the coal mine in for climate change-induced changes to water supply systems,” Ross Young, executive director of the Water Services Association of Australia, told The New York Times.

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.

Russian President Dmitry Medvedev has declared a state of emergency in seven Russian regions because of wildfires fuelled by a heatwave. The death toll from the fires has risen to at least 34. The Russian emergencies ministry said 500 new blazes had been discovered over a 24-hour period, but most had been extinguished. Homes have been burnt in 14 regions of Russia, the worst-hit being Nizhny Novgorod, Voronezh and Ryazan. The state of emergency was announced in a decree that also restricted public access to the regions affected. Moscow is again shrouded in smoke from peat and forest fires outside the city. The fires, caused by record temperatures and a drought, have affected cereal harvests, driving wheat prices up.

Russians are bracing themselves for another week of high temperatures, with forecasts of up to 40C (104F) for central and southern regions. Officials also expect stronger winds in some regions, which will fan the flames. By Sunday night, wildfires were still raging across some 128,000 ha (316,000 acres).

Thousands of people have lost their homes and nearly a quarter of a million emergency workers have been deployed to fight the flames. President Medvedev described the situation on Saturday as a "natural disaster of the kind that probably only happens every 30 or 40 years". Moscow doctors say the elderly and toddlers should wear gauze masks outdoors.

As she did for winter 2010, this summer Mother Nature has truly outdone herself, this time by brewing up a miserable combination of heat and humidity that has enveloped not only the northeastern U.S., but much of the Northern Hemisphere as well. As Ian Livingston reported on Saturday, July was the warmest single calendar month of all time in Washington (tied with July 1993). The warmest day in the city was July 7th, when the temperature soared to 102 degrees Fahrenheit at Reagan National Airport. The day before, the temperature rose to a sweltering 105 F at Baltimore-Washington International Airport. In total, Washingtonians sweated through 21 July days during which temperatures exceeded 90 degrees. Baltimore set a new record for the average daily high temperature, which was 92.5 degrees, beating July 1988's 91.9 degrees. New York City and Philadelphia experienced their second-warmest months since records began in the late 1800s. New York recorded an average monthly temperature of 81.3 degrees, which was 4.8 degrees above the July average. The warmest July on record there occurred in 1999, when the average temperature was 81.4 degrees.

Although long-term global climate change doesn't directly cause a particular heat wave, the pronounced warming trend in global average temperatures during the past century has increased the odds of more frequent and severe heat waves. For example, scientists have partially attributed the deadly 2003 European heat wave, which killed tens of thousands, to manmade climate change.

Russia Heat Wave Statistics Staggers the Imagination

IT IS AS IF THE RUSSIAN HEARTLAND SHIFTED ONE THOUSAND MILES SOUTH That the month of July 2010 was hot in Moscow could rank among the foremost understatements in the world of "weather speak." For one thing, the highest temperature on record (in roughly 130 years of Moscow weather records) was reached on July 29, this being 38.2 C, or 100.8 F. This broke the previous high mark of 37.5 C set only three days earlier, on July 26. This was nearly tied on July 28. All of this is extraordinary, given that the normal high for this, the hottest time of year, is only 23 C. Moreover, July 2010 was the hottest July in the climate record of Moscow, as well as the hottest month overall. Thanks to Loepa, writing from Brasil (of all places!), I have it that the old record for warmest month in Moscow was 23.3 C, or 73.9 F, versus normal of about 17 C, or 63 C. What about this July? How about 26.1 C, or 79.0 F. So that is nearly a 3 C (and more than 5 F) gap. It is as if Moscow were shifted a thousand miles to the south. For perspective, the normal average temperature of July in Washington, D.C., is 26.2 C, or 79.2 F, according to the ADC database. Moscow has thus experienced roughly the weather (less the usual steamy humidity and thunderstorms) that is normally expected in the city of Washington, D.C., which lies 1,890 km/1,170 miles nearer to the equator! ST. PETERSBURG HAS ALSO ENDURED EXTREME TEMPERATURES I do not have full climate records for St. Petersburg, but I do know about July 2010. The AccuWeather.Com database shows a monthly mean temperature of 24.2 C, or 75.5 F. Normal mean July temperature is 15.2 C, or 59.4 F. Yes, that is even higher above normal than was Moscow. The city of Indianapolis has a normal mean July temperature of 24.2 C. Yet Indianapolis is 2,250 km/1,400 miles nearer to the equator than St. Petersburg. I do not say that this is a rigorous "apples-to-apples" comparison. Rather, it is to get a rough idea of how skewed the weather has been this summer in the Russian heartland. AND IT IS NOT OVER YET... As of this writing, the highest temperature thus far on Wednesday, Aug. 4, is 36.6 C, or 98 F, in Moscow. St. Petersburg has reached 33.3 C, or 92 F. Searing heat has invaded eastern Belarus, where readings to 37 C or 38 C have been reached. In the Ukraine, the worst of the heat has backed westward to Kiev, where August 4 has become the hottest day (37 C to 38 C, or near 100 F) of the summer thus far. And near 40 C yet again in Luhansk. The GFS numerical forecast model shows widespread extreme high temperature departure, for at least another week, throughout European Russia along with stretches of her western neighbors.

POQUOSON -- Hurricane Isabel flooded Sandy Firman's house in 2003, and now routine storms drive water into the roads and marshes close by. Several homes in this low-lying city, including Firman's, have been elevated about 10 feet to keep them above the ever-closer waters. "We used to not have it like that," said Firman, who has lived in Poquoson all of his 46 years. "But something has changed around here." One big thing that has changed is the sea level, which is rising -- an increase blamed on global warming.

In southeastern Virginia, the rising sea is a problem now, and scientists expect it to get much, much worse.

During the last ice age thousands of years ago, the weight of glaciers pushed down land in what is now the northern U.S. When those glaciers receded, that northern land began to rise, and land here started sinking, as if Virginia were on the end of a see-saw after the other rider got off. Throughout most of the 20th century, the sea level in southeastern Virginia rose about twelve-hundredths of an inch a year -- or 12 inches per century. But over the past two decades or so, the rate appears to have doubled in places. About half of that increase seems to be due to the sinking of land, and half to global warming, said Carl Hershner, a professor at the Virginia Institute of Marine Science. "And the forecast -- this is the scary part -- is for that acceleration to rise," Hershner said. Scientists say the future increases will be caused almost entirely by climate change. "We will still be sinking," Hershner said, "but that will be a smaller and smaller fraction of the change we experience."

Swdwmsri Narzary, 19, a nimble weaver, rests her fingers on her loom and gets a faraway look when asked to recall her last few years of struggle dealing with the pressures of climate change. Orphaned at an early age, Swdwmsri lived with her elder brother and his family in Bijni, a rural village in Assam province's Chirang district. But increasingly unpredictable weather conditions - drought one year, incessant and untimely rains the next - made life gradually harder as the family's crops repeatedly failed. With the family on the verge of starvation, Swdwmsri had to drop out of school. Her brother decided not to waste money sowing new crops and instead used his remaining cash to migrate to a nearby city, Guwahati, in search of a job.

New daily high temperature records were set in many cities, with June 2010 ranking as the hottest June on record for Delaware, New Jersey, and North Carolina.

The unusual warmth in the highly populated South and Southeast resulted in the second highest June REDTI value in the 116-year record. For the first half of 2010, large footprints of extreme wetness (more than three times the average footprint), warm minimum temperatures ("warm overnight lows"), and areas experiencing heavy 1-day precipitation events resulted in a Climate Extremes Index (CEI) that was about 6 percent higher than the historical average.

The nationally-averaged temperature for June was much warmer than normal. A deep layer of high pressure dominated much of the eastern United States

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.

The first heavy downpour of the morning had carried debris and vegetation into the 2.7m by 2.7m culvert, starting a chain of events that led eventually to the flash flood.It was choked where it drained into the side of Delfi Orchard, so water was directed only into the side along Forum the Shopping Mall.When a second intense rainstorm the same morning added more water to the drains within a short period of time, the canal overflowed and water gushed up to the surface of Orchard Road, causing the worst floods there in 26 years.

Although national water agency PUB alerted the traffic police when the sensors at the start of each Stamford Canal channel indicated water levels were at 75 per cent, the water level rose too abruptly to get the alert out to shopkeepers.At a press conference yesterday, the PUB said the heavy rains were responsible for sweeping the debris into the drain.

What was unusual about Wednesday's storm was its intensity and its two peaks, he said. The first peak could have brought a certain amount of debris, and there was no way for PUB officers to safely check and clean it out. The next peak soon after might have brought even more debris.

Having just completed the warmest spring on record, Washington, DC, and other cities in the eastern United States are enduring a record-breaking heat wave that is consistent with climate change. Last week’s temperatures in Washington D.C. broke a century-old record and forecasters expect this month to be the hottest June on record for the area. These patterns fit the long-term trends of more frequent heat waves driven by climate change

Characteristics of the current heat wave in the Washington, DC area include record daytime highs, record high overnight lows, and the long string of days above 90 degrees, all of which are consistent with the trends in the U.S. driven by climate change. The back-to-back heat waves experienced in Philadelphia this June also reflect the long-term global warming trend, as do the record-breaking average temperatures witnessed this past spring in Washington D.C., Maryland, Pennsylvania, and New Jersey.
