According to the National Weather Service in Boulder, after a high of 69°F at 2:27 p.m. on Sunday (Feb. 18) Denver's official low hit -3°F just over 40 hours later at 6:45 a.m. on Tuesday (Feb. 20).
The 72 degree drop tied for the 8th biggest swing ever noted in a period of two days or less. It also landed in the top 20 biggest temperature swing events for Denver since records began in 1872.

Every year since, diplomats have met at United Nations summits to, sometimes successfully, negotiate new treaties and agreements to cut greenhouse gas emissions. Most recently, nearly 200 nations signed onto the Paris climate accord.
The Paris accord went into effect in 2016, but after one year global emissions rose two percent, largely on economic activity in China.
The Washington Post reported on Tuesday that countries' Paris accord commitments were "falling short." The Post admitted, "The euphoria of Paris is colliding with the reality of the present."
Coronet Peak has had about 10-15cm of snow at the base of its ski fields, and snow drifts of more than one metre have blanketed the Remarkables.
Ski manager Ross Lawrence told Stuff across the area there was 50cm of snow on average, but he didn't expect it to last long.
'Remember it is only February so the sun will come out again soon,' he said.

Detroit, Michigan, west of the river - Windsor, Ontario, east of the river: why is it mostly residents of Windsor who hear it?
The Windsor Hum, can be heard throughout Windsor, Ontario, home to almost 220,000 people, but it has been reported 90 miles away in the US city of Cleveland.
Complaints of the part noise, part vibration arose in 2011, when locals initially compared it to rattling windows.
Comment: Interesting, that's the same year the 'strange sky sounds' phenomenon really took off.
But as the hum began to vary in its intensity, droning on for days at unbearable levels, distressed locals have taken to all forms of social media to question their hearing and vent their frustrations.
Comment: It may not be noise pollution, i.e. man-made. It could also be at least partly natural, but yes, 'new' at the same time.
What's striking in this particular case is that something about the location apparently 'anchors' the noise(s) there very frequently, if you'll excuse the pun. Zug Island, located in the river between the two cities, might in some way function as an 'anchor' or 'transducer' of electrophonic geomagnetic frequencies.

The 1.42-metre-long female porpoise was showing moderate body decay when it was spotted at Tai Long Wan.
A further two bodies were found in Sai Kung. One was a juvenile, 0.97-metre-long porpoise, which was found at Ham Tin Wan. The porpoise had three visible wounds, possibly the result of being hit by a boat's propellers. Another female, adult porpoise was found in the sea off Silverstrand Beach.
The fourth creature, a 1.31-metre-long female, was found near the Hong Kong University of Science and Technology pier on Sunday in a moderately decomposed state.
All four bodies were sent to the Ocean Park Conservation Foundation (OPCF) for further investigation.
The parents of the boy, Ibrahim had taken him along with them to a groundnut field. Since the boy was sleeping, they kept him on a swing nearby and went for their work.
However, the boy was attacked by two stray dogs and his screams fell short due to the sounds of the groundnut crusher machine.
The parents later tried to locate their son and found the body half a kilometre away as they heard two dogs growling at each other.
The NUI Galway (NUIG) study published today found that 73 per cent out of 233 deep water fish examined had ingested plastic particles.
According to the study, the ingestion of microplastics by these animals may cause internal physical damage, inflammation of intestines, reduced feeding and other effects.
Marine scientists took dead deep sea fish from midwater trawls in the Northwest Atlantic Ocean from a depth of up to 600 metres using large fishing nets.

Indonesian schoolchildren walk together at Sipandak elementary school in Tiga Pancur village in Karo, North Sumatra on Feb. 19, 2018, as thick volcanic ash from Mount Sinabung volcano rises into the air following another eruption. Sinabung roared back to life in 2010 for the first time in 400 years and has remained highly active since.

On February 14, 2018, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite acquired data for these false-color images of North America's Great Lakes. The images were made from a combination of infrared and visible light (MODIS bands 7-2-1) in order to better differentiate between snow and ice (teal) and clouds (white). Open water appears black, though some of the dark areas likely have a layer of clear ice (without snow cover on it). For a detailed map of ice extent and thickness on the Great Lakes, visit the Great Lakes Ice Analysis page.
Norway's waterways and energy directorate NVE reported that there hasn't been as much snow in the hills around Oslo, for example, since 1995. In some areas, snow depths haven't been so large since the mid-1960s.
There's been at least 80 centimeters at low elevations this winter and more than a meter at higher elevations, with the hills around suburban Bærum, for example, reporting around 120 centimeters of snow on the ground.













Comment: It's unbelievable that these scientists are still blathering on about emissions and global warming when their research is debunked time and time again. They have bills to pay too, we suppose. Meanwhile, take a gander at some global warming solutions:
