In the slanting, late-afternoon summer sun, the fields around the small Australian town of Ouyen almost 450km north-west of Melbourne turn the colour of honey. The edges shimmer with silver, that old cruel trick of feigning water where it hasn't rained for weeks. Summer is always hot out here in the sparse, flat Mallee, but this year is shaping up to be particularly harsh.

It was 26.1C as the sun rose on Tuesday over the small Victorian town of Ouyen, the Mallee town of 1,170 people whose forecast high of 49C would break the state's temperature record of 48.8C set in Hopetoun on Black Saturday in 2009. The area has not recorded a drop of rainfall all January, and only 13.6mm in December. The fire danger rating on Tuesday was extreme.

At 30-30 the Dutchman conjures up a 210-kmh serve down the middle, and follows it up with an ace to clinch his first hold. When he connects with that first serve sweetly it is a thing of ludicrous power. Share Updated at 03.23 EST Van de Zandschulp has only been broken once in the tournament himself, so Djokovic is unlikely to get anything for free there.

Lyn Cheedy, a Yindjibarndi elder, takes her grandson to the pool most afternoons. At first, the cold water is refreshing. Then a gust of wind hits. The wind burns you, she says. I have to keep splashing my face, and your hair is drying that quick it's like you're sitting in front of an oven. In the Pilbara, heat and cyclones are nothing new, says Cheedy. Her people have survived extreme conditions for millennia.

The highest temperature that Jonathan Paul has ever recorded in a London Tube station is about 42 Celsius, or 107.6 Fahrenheit. Paul, a researcher at Royal Holloway, University of London, uses his thermometer-equipped smartphone to take such readings. 42C is the kind of heat that would send someone running to the nearest air-conditioned building. Underground, though, they can't. There's nothing but stifling tunnels and screeching trains down here.

Coastlines around the world are threatened by flooding, erosion, and saltwater incursions into wells and community water supplies. In the United States, the Southeast and Northeast are most susceptible to hurricane and storm surge flooding, as well as losing freshwater supplies due to saltwater incursion as the sea rises. In the West, coastal erosion, including the loss of homes on bluffs above Pacific beaches, and water supply issues are the primary concerns facing homeowners who live near the ocean.

The researchers are not talking about the effects of solar radiation on the skin, but biological aging. Unlike chronological age-that answer that you give when asked how old you are-your biological age reflects how well your cells, tissues, and organs are functioning. Biological age can be calculated by looking at physiological and molecular markers in the body as well as by using various tests, for instance by measuring lung function, cognitive ability, or bone density.

Residents of the Western U.S. sweltered in a heat wave Saturday that hospitalized some people, with temperatures forecast to hit dangerous levels throughout the weekend in Washington, Oregon, Southern California, Nevada and Arizona. About 1.2 million people were under extreme heat risk, meaning temperatures were expected to stay dangerously high with no relief overnight. The largest area under the warning was around Tucson, Arizona, where the National Weather Service forecast highs between 102 and 107 degrees Fahrenheit (39 and 42 degrees Celsius).

The association said that from the beginning of June to at least the end of August, the opening hours of the Colosseum area should run from 7am to 8.15pm. For three years, we've been asking for the opening of the whole park to be brought forward to 7am and for closing to be postponed by an hour, said AGTA. These changes would benefit the public health of everyone: visitors, guides and other workers.

"I don't think it's the product," says Brian Lowit, the owner of Mount Desert Island Ice Cream in Mount Pleasant. "People are just like, 'I'll stay cooler by staying in my house.'"

On July 23 more than 35 million people are at a major or extreme risk of heat effects, according to the National Weather Service.

Despite the sweltering heat today in Portland, with temperatures nearing 100, residents are advised to keep cool, as not everyone is equipped for such weather.

When extreme heat hits the Boston area, emergency departments are packed with people who are dehydrated, experiencing kidney or heart problems, or are having heat cramps. The stress of the heat exacerbates those conditions, and we'll see a 10 percent jump of people in the emergency department not just for heat illness, but also weakness or syncope or other conditions due to the heat.

Starting on Saturday June 21, nearly 20 extreme-weather records were broken in a single day, including in Mitchell, SD, which broke its daily high when temperatures climbed to 104 degrees.

The National Weather Service warns that a dangerous heat wave, combined with high humidity, will blanket much of the central and eastern US, with temperatures possible above 100°F.

I actually watched him. He drank a bunch of water. I mean a bunch, and then he went right out and got rid of it.
