1. Death Valley, US

California 's Death Valley holds the record for the highest reliably reported air temperature in the world, 56.7°C in July, 1913. In midsummer the desert region averages around 47°C and is the driest place in the US .Hardly the environment you would expect to find hiking trails, resorts, and a bewilderingly green golf course.
Ringed by mountains, Death Valley plunges to 86 metres below sea level, which helps explain the heat. It's around a three-hour drive from Las Vegas . Head there around Christmas to miss the crowds and make sure you have a rugged vehicle - getting stranded is not recommended.

2. Al-Aziziyah, Libya

The Foreign Office advises against all travel to Libya .
Around 25 miles south of Tripoli lies Al-Aziziyah, where - on September 13, 1922 - the world experienced its hottest air temperature ever recorded: 58°C. That is, until the World Meteorological Organisation announced in 2012 that the recording was invalid for a number of reasons, one of which was that the record keeper on that day was not the usual employee but an inexperienced observer. This ruling handed the record heat back to Death Valley, California, for its 56.7°C temperature

3. Dallol, Ethiopia

At Dallol, in the Denakil Depression, Africa dips to a depth of 116 metres below sea level, and the temperature soars. Dallol has the world's highest average temperature for an inhabited place, calculated at 34.6°C. Head across the salt plain to the Dallol volcano , the lowest on Earth, if that's not hot enough for you. Cooling temperatures from November to March make a winter visit more viable.

4. Dasht-e Lut, Iran

Between 2003 and 2010, this desert plateau recorded the year's highest surface temperature, cracking the 70°C barrier, reaching 70.7°C. Coupled with the heat, the Dasht-e Lut vies with Chile's Atacama Desert for the title of the world's driest spot, and across a large area of the central Lut not a single creature survives, even bacteria. The desert's east has great visitor potential, with classic wind-sculpted dunes rising to heights of 500 metres. Yazd ( Iran 's driest city) borders the deserts of Dasht-e Lut and Dasht-e Kavir. To really head into the desert you'll need to team up with local nomads.

5. Bangkok, Thailand

Crowned as the planet's hottest city by the World Meteorological Organisation, Bangkok has an annual mean air temperature of around 28°C. The months from March to May are the hottest, when the smog-saturated city experiences nearly 35°C days with 90 per cent humidity. The city is only slightly cooler in December (around 26°C) but humidity remains high, making Bangkok rather uncomfortable year-round.

6. Vostok station, Antarctica

We're on to coldest now, in case you didn't realise. Located near the South Geomagnetic Pole, and at the lofty height of around 3,500 metres above sea level, the Russian research station at Vostok is perpetually cold, but never more so than on July 21, 1983, when it registered the coldest recorded air temperature on the planet at the time: -89.2°C. Its
record was broken in 2013 when a NASA satellite revealed a temperature of -93.2°C, the new coldest on record, was reported elsewhere in East Antarctica back in August 2010.
The key geographical feature around Vostok is Lake Vostok. One of the world's largest lakes, it is buried beneath four kilometres of glacial ice.

7. Eureka, Canada

The Eureka research base on Canada's far-northern Ellesmere Island (pictured) is one of the world's coldest inhabited places. It straddles the 80th parallel and was created as a weather station in 1947. The average annual air temperature is around -20°C. In winter that drops to around -40°C. It is mildly warmer in the summer but even so, since records began the temperature has never exceeded 20.9°C, first reached on July 14, 2009.

8. Oymyakon, Russia

In 1933, in the republic of Yakutia, around 350 kilometres south of the Arctic Circle, the village of Oymyakon slipped to the numbing frostiness of -67.7°C, the coldest recorded air temperature in the northern hemisphere (apart from Verkhoyansk, where a temperature of -67.8°C was recorded in 1885). A plaque in the village is said to commemorates the event, but expect a long day of rugged driving from Yakutsk (around 800 kilometres to the west) if you plan to pay homage to this mercury marvel. Hitch a ride aboard one of the tankers that transport water to the town (the native water is all frozen).

9. Denali, US

Denali, or Mount McKinley, the highest peak in North America, has long been considered the coldest mountain on Earth, with its lowest recorded temperature being around -73°C, reported in 1913 at the 4,600 metre feet level. To experience the 6,194 metre-high Alaskan peak you must be a mountaineer, but you can ponder it from slightly warmer locales with a visit to the Denali National Park.

10. Ulaanbaatar, Mongolia

Perched on the Mongolian steppe, around 1,300 metres above sea level, Ulaanbaatar has often been described as the world's coldest capital city. In January, the air temperature rarely rises above around -16°C. There are places to escape the chill, however: head to one of the city's impressive collection of museums (including the Camel Museum and the Museum of Political Persecution), or seek out the body heat of nearly 150 monks at Gandantegchinlen Khiid - Mongolia's largest monastery.

nice and interesting

Nature is pure Magic.

E gud!

Winterfell and the lands of the wildings and White walkers are colder.

wow!!
I pity those pple living in oymyakon!!
oga oo!! see there costume

This list is incomplete without mentioning Maiduguri

U

This thread is hot....

It is cool like that too.....

Interesting!

imagine only USA has the coldest and hottest.

I think all the northern mid-west states in the U.S are the coldest states in the union... Minnesota, North/Douth Dakota, Wisconsin, Iowa, Montana, Colorado etc...

Northern Nigeria nko?
