Polar Bear Scare Unmasked: The Saga of a Toppled Global Warming Icon [another look]

polarbearscience

For almost twenty years, , we’ve endured the shrill media headlines, the hyperbole from conservation organizations, and the simplistic platitudes from scientists as summer sea ice declined dramatically while polar bear numbers rose. This video of mine from two years ago, which deconstructs the scare, is worth another look as International Polar Bear Day approaches with its associated ‘save the polar bear’ rhetoric.

Jet stream not getting ‘wavier’ despite Arctic warming, say researchers

Tallbloke's Talkshop

Credit: Wikipedia
This contradicts climate alarmist claims such as: Global Warming Is Messing with the Jet Stream. Whether 40 years of data is enough to establish what is ‘normal’, is another matter. The fastest jetstream on record of 231 mph has only just been set, we’re told.
– – –
Rapid Arctic warming has not led to a “wavier” jet stream around the mid-latitudes in recent decades, pioneering new research has shown.

Scientists from the University of Exeter have studied the extent to which Arctic amplification—the faster rate of warming in the Arctic compared to places farther south—has affected the fluctuation of the jet stream’s winding course over the North Hemisphere, reports Phys.org.

Recent studies have suggested the warming Arctic region has led to a “wavier” jet stream—which can lead to extreme weather conditions striking the US and Europe.

However, the new study by Dr. Russell Blackport…

Sea Level Rise Is Accelerating (If You Ignore Pre 1970 Data!)

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

Want to know how sea level in your area is changing due to global warming and other factors? Our ‘report cards’ can help. Updated by the Virginia Institute of Marine Science each year as annual tide-gauge data become available, they display recent sea-level trends and project sea-level height to the year 2050 for 32 localities along the U.S. East, Gulf, West, and Alaskan coasts.

Report Card Components

Our report cards have 3 components: the 2050 projection, recent trends in the rates of sea-level change, and an explanation of processes affecting sea level at each locality.

The annotated chart below, using the latest data from Norfolk, Virginia, briefly explains the data and statistical approaches we use in our 2050 projections. Visit an individual locality for details on all its report-card components. You can also compare sea-level trends, projections and processes among localities and by region. For full…

New Record Low Temperature For Greenland Set Last Month

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

 image

Summit Camp, also known as Summit Station, is a year-round research station on the apex of the Greenland Ice Sheet. It is located some 10,500 ft (3,200 m) above sea level, and it’s data is often cited by climate alarmists claiming “Greenland Is Melting Away Before Our Very Eyes” and other such nonsense…

Adding to the list of temperature measurements those alarmists will likely ignore –or won’t even get to hear about given the mainstream media’s warm-bias– is Summit Camp’s preliminary low of -86.8F (-66C) set at 11:13 PM on January 02, 2020.

The reading, once confirmed by the DMI, will enter the books as Greenland’s coldest-ever recorded temperature–not only at Summit Camp, and not only in January, but of anywhere across the island, and of any month of the year.

Extremes and Averages in Contiguous U.S. Climate – Part 10: The Contiguous U.S.

Bob Tisdale - Climate Observations

This is the last in a series of ten posts that present graphs of NOAA precipitation, drought (Palmer Drought Severity Index, PDSI), and temperature (TMIN, TAVG, and TMAX) data for the contiguous United States (and the 9 NOAA Climate Regions thereof) for the most-recent 100 years (1919 to 2018) of data that were available at the time that I prepared my paperback book Extremes and Averages in Contiguous U.S. Climate, which is the source of the graphs. That book was first published in May 2019. The subtitle of the book isGraphs of 100 Years of NOAA Contiguous U.S. Climate Data (2018 Edition) – A Book That NOAA Should Have Published. Links to the nine earlier posts in this series can be found toward the end of this one.

What If the US Banned Fracking?

Science Matters

Other posts have addressed the murky science underneath the claim that burning fossil fuels makes the earth warmer, and the alarmist claims that a warmer world is more dangerous than a colder one. This post takes up the issue that even if rising human CO2 emission were causing dangerous warming, what are the likely consequences of policies to cut down on carbon-based energy. Text below in italics comes from sources listed as links at the end.

This issue arises in the US context because presidential candidates of leftist stripes have pledged to do away with fracking operations and forego the resulting boom in natural gas and tight oil production.

The Narrative

“I will ban fracking—everywhere.”
— Elizabeth Warren

“Any proposal to avert the climate crisis must include a full fracking ban on public and private lands.”
— Bernie Sanders

“I favor a ban on new fracking and a rapid end…
