The Guardian begrudgingly admits "weakening of Gulf Stream could bring colder UK winters"

Deep snow drifts, skating along frozen rivers and weeks of sub-zero temperatures used to be normal features of a British winter, but they are rare today. However, in an ironic twist, global warming may help conditions like this to return in the coming decades, by disrupting the Gulf Stream - the warm ocean current responsible for taking the chill off north-west Europe.

The Gulf Stream is part of a larger ocean conveyor belt known as the Atlantic meridional overturning circulation (Amoc), which moves warm water northwards in the upper layers of the Atlantic Ocean, and colder waters southwards at lower depths. Previous research has shown that a slowdown of Amoc appeared to trigger a global cold snap 13,000 years ago. In 2018 scientists revealed that the Gulf Stream was at its weakest in 1,600 years.

By investigating the impact of Greenland meltwater and rainfall on Amoc, researchers found that thankfully there is very little chance of a complete shutdown in the next 1,000 years, but instead they show there is a 15% chance of a temporary shutdown in the next 100 years, which would likely trigger cooler conditions in north-west Europe. But acting fast to limit global warming will reduce the chances of being thrown into a chill.

Comment: While The Guardian tries to spin this as an unlikely event their bias blinds them to the plentiful research that shows global cooling has already begun: Also check out SOTT radio's:

Bhutan experiencing a colder winter than normal

Many people, including commuters and residents were taken by surprise when it snowed in Gedu on the night of January 4, stranding vehicles and causing inconveniences to commuters.

Official records indicate Gedu received its first snowfall this year. Some Gedu residents said the place received a light snowfall in 2008. "But this is the first time we are receiving snowfall of such thickness," a local resident said.

Many people attributed the snowfall to climate change.

The National Centre for Hydrology and Meteorology (NCHM) officials, however, said western disturbance along with convective clouds, which were fed with continuous moisture from the Arabian Sea caused the snowfall with hailstorm and thunderstorm in Gedu.

Extreme cold winter weather in Lapland
Visitors to Lapland have the opportunity to experience a proper snowy winter with a record amount of snowfall blanketing the region.

In many places there's 90cm of snow - for example today in Sodankylä there's 89cm and in Kittilä 88cm have been recorded, around 30cm more than usual.

"It's a record for the time of year" says Meteorologist Anniina Valtonen at the Finnish Meteorological Institute.

"Typically in January Lapland really does not have snow cover above 80cm. Such snowfall occurs once every thirty years" she explains.

Parts of the South Island received a dusting of snow overnight, reflecting cooler summer temperatures across much of the country.

Webcams from Cardrona and the Remarkables ski resorts showed snow falling overnight on Sunday and on Monday morning.

Temperatures on the Remarkables were forecast to hover between -1C and -4C on Monday,
with Cardrona only slightly warmer.

MetService meteorologist Lewis Ferris says snow at this time of the year is "not unusual" and more snow could fall down to 900m around Fiordland on Monday given the mixture of wet conditions and cool southerly winds.

The cooler temperatures were due to a "cold southerly intrusion", Ferris said, with Gore and Invercargill set to get the worst of the colder temperatures.

25 plus locations across south Australia have just suffered their coldest January days ever - Mainstream Media Silent

auss map
Parts of South Australia have just shivered through some of their coldest January days on record — with Adelaide missing out on beating its 1970 record by just 0.7C.

The temperature at Adelaide's West Terrace weather station reached just 16.6C on Sunday — about 13C below the average for the time of year, and below the city's previous lowest January max temp on record, the 17.1C from 1970.

However, because of the controversial way the BOM now measures Australia's maximum temperatures "as the highest reading during the 24 hours to 9am each day," an observation of 17.8C at Adelaide's West Terrace site just before 9am on Monday has gone down as the official max for the 24 hour period.

Snow depths have passed the three metre (10 foot) mark in Western USA and the two metre mark in western Canada after heavy snowfall hit the region.

Ski areas have reported up to 2.3 metres (nearly eight feet) of snow in the past 7 days, the biggest accumulation reported by Mt Baker, in northern Washington state close to the US border. It is also posting the deepest base on the continent at 3.1 metres (10.3 feet).

Mt Baker holds the record for the most snow ever reported in one season, and for the most snow on average each season (both unofficial records); 29 metres / 95 feet set in winter 98/99 and 16.3m / 54 ft respectively.

Thousands are without power, according to The Weather Network, as nearly 40 centimetres have fallen so far, and the number is expected to rise as it keeps falling.

Environment Canada has issued a weather warning for the province, and it is likely that more of the winter precipitation will arrive on Wednesday, so get ready, Newfoundlanders!

Wind speeds are extremely high, and traffic has been a mess. The winds are reportedly travelling at up to 80 km/h across the province, according to TWN.
