An Exceptional Year? Hardly, Mr McCarthy

by P. Homewood, January 1, 2020 in NotaLotofPeopleKnowThat


 

The year as a whole has been remarkably unremarkable, as far as temperatures are concerned, ranking only the 24th warmest on record since 1659, and not as warm as even 1733, 1779, 1834 and 1868:

A closer look at the years since 1980 confirms that the 10-year average has been falling since 2006:

2019 Science Refutes Climate Alarm On Every Front… Shrinking Deserts, Growing Islands, Crumbling Consensus, Weaker Storms, Cooler Arctic Etc. Etc. Etc.

by P. Gosselin, December 31, 2019 in NoTricksZone


2019 science: Absolutely no climate alarm 

No alarm on every aspect: stable polar ice, normal sea level rise, no consensus, growing snow cover, less tropical storms, tornadoes, shrinking deserts, global greening, predictions wrong, models flawed, climate driven by sun, ocean cycles, biodiversity, warmer 1000 years ago…etc…

2019 saw a great amount of new science emerge showing that there’s nothing alarming or catastrophic about our climate. 

Some 2019 scientific findings

Need to make a presentation showing there is no climate alarm? The following findings we reported on in 2019 will put many concerns to rest.

Hundreds of peer-reviewed papers ignored by media

What follows are some selected top science-based posts we published here at NoTricksZone in 2019. These new findings show there is absolutely no climate alarm.

Hundreds of new peer-reviewed papers, charts, findings, etc – which the IPCC, activists and media ignore and even conceal. No wonder they’ve gotten so shrill.

2019: The End Of A Decade When Climate Alarmism Tipped Into ‘Climate Crisis’

by J. Jessop, December 30, 2019 in ClimateChangeDispatch


In the final days of 2019, there is much to reflect upon events of the past year and, with the closing of the second decade of the 21st century, much to reflect upon how climate change alarmism has itself alarmingly morphed into something much more dangerous, visceral, urgent, ideologically driven and immediate as regards public perception and societal impact.

A decade during which global warming faded into obscurity (on account of the fact that there wasn’t any from 1998-2013) to be replaced almost universally by the more politically correct term of ‘climate change’, which has itself now been largely displaced in activist circles and the media by the terms ‘climate emergency’ and ‘climate crisis’.

Ironically so, because, bereft of an actual climate crisis, alarmist scientists and activists have proceeded to invent one, linguistically, as in the case of the Guardian’s newly introduced style guide and by co-opting extreme weather events and their impacts into the general narrative.

Judith Curry has written an excellent push back article to the lukewarm attempt by Wallace-Wells, among others, to dial down the alarmist hype in the light of the RCP8.5 criticisms, whilst still maintaining the necessary ‘scary’ projections of future warming.

Another year, and still no increase in severe U.S. tornadoes

by P. Homewood, December 27, 2019 in WUWT


Climate scientists love to blame every bad weather event on global warming. Yet we never hear them cite climate change for the relative absence of bad weather!

One such example are tornadoes in the US, where we now have several decades of carefully collated data.

With the year near an end, we know that the number of tornadoes has been above average this year, though well below 2008 and 2011. Primarily this is due to several outbreaks in February and April:

The 2019 Atlantic Hurricane Season

by P. Homewood, December 11, 2019 in NotaLotofPeopleKnowThat


The Atlantic hurricane season has now officially ended, so let’s check the numbers.

https://www.aoml.noaa.gov/hrd/tcfaq/E11.html

http://rammb.cira.colostate.edu/products/tc_realtime/season.asp?storm_season=2019

There have been six hurricanes in total, including three major ones, Dorian, Humberto and Lorenzo. Coincidentally both numbers are the same as the average since 1950.

According to NOAA’s Hurricane Research Division, many hurricanes were missed in the earlier decades. Systematic aircraft reconnaissance began in 1944, but this only covered half of the Atlantic basin, until daily satellite monitoring started in 1966.

2019 the Third Least-Chilly in the Satellite Temperature Record

by Roy Spencer, December 6, 2019 in WUWT


It’s that time of year again, when we are subjected to exaggerated climate claims such as in this Forbes article, 2019 Wraps Up The Hottest Decade In Recorded Human History. Given that the global average surface temperature is about 60 deg. F, and most of the climate protesters we see in the news are wearing more clothing than the average Key West bar patron, I would think that journalists striving for accuracy would use a more accurate term than “hottest”.

So, I am announcing that in our 41-year record of global satellite measurements of the lower atmosphere, 2019 will come in as 3rd least-chilly.

For the decade 2010-2019, the satellite temperatures averaged only 0.15 C higher than in the previous decade (1990-1999). That’s less than a third of a degree F, which no one would even notice over 10 years.

If you are wondering how your neck of the woods has fared this year, the latest year-to-date plot of 2019 temperature departures from the 30-year average (1981-2010) shows the usual pattern of above- and below-normal, with little visual indication that the global average for 2019 is now running 0.36 deg. C above normal.

ORANGE ‘HEAVY SNOW’ ALERTS ISSUED ACROSS SPAIN

by Cap Allon, November 11, 2019 in Electroverse


Following Spain’s weekend of surprise early-season-snow, ORANGE ALERTS have now been issued across the country as the prospect of yet more severe wintry-weather looms — residents have been urged to prepare.

Spain’s state weather agency AEMET had predicted last weekend’s “polar front” and subsequently placed parts of Mallorca and Menorca on orange alert. Now though, an additional 33 provinces have been placed under winter-weather alerts across the country -from Lugo in the north, to Malaga in the south- as further Arctic plunges appear set to engulf ALL of Western/Southwestern Europe this week.

A staggering 40 cm (15.8 inches) of snow buried Northern Spain’s ski resorts over the weekend, including Fuentes de Invierno, in Asturias — as reported by murciatoday.com.

Snow also fell in more unexpected areas, like Port de Pollenca a small town in Northern Majorca.

UK ON COURSE FOR AN HISTORICALLY COLD NOVEMBER

by Cap Allon, November 19, 2019 in Electroverse


After decades of being lectured by the Met Office -among others– that global warming will bring an end to extreme-cold temperatures, the UK still somehow keeps-on clocking them — yet another example of how simple real-world observations can unravel the AGW-ruse.

Brits have been suffering-through an historically cold month, too — November’s average temperature has held well-below the norm for the first 17 days, continuing October’s dramatic cooling trend:

The Central England Temperature (CET) record measures the monthly mean surface air temperatures for the Midlands region of England, and is the longest series of monthly temperature observations in existence anywhere in the world.

Its mean reading for November 2019 (to the 17th) is sitting at 6.6C — that’s 0.7C below the already cool 1961-1990 average, the current standard period of reference for climatological data used by the WMO.

In the 360 years of CET data, there have only been 10 other years with an November average temperature of 6.6C — these are 1804, 1833, 1835, 1849, 1886, 1932, 1941, 1949, 1977, 1980.

Note also how the majority of these years fall in or around solar minimums of the past (1804, 1849, and 1980 being the only exceptions).

N. Hemisphere In Hypothermia! Widespread Early Winter…”Historic Snowstorms”…”Record Books Rewritten”

by P. Gosselin, November 13, 2019 in NoTricksZone


Winter has not even officially arrived, but already large areas of the northern hemisphere are seeing “historic snowfalls”, frigid temperatures and even avalanche alarms.

The Northern Hemisphere has certainly caught a major cold, one certainly not caused by the human CO2 virus. Instead of fever, parts of the northern hemisphere are in hypothermia!

Alarmists, media desperate

Though global warming scientists will never admit it, they are really surprised and stunned. All that is left for them is to make up some cockamamie warming-causes-cold explanations and hope there are enough severely stupid among the media and masses to believe it.

“United States — Rewrite the Record Books”

Beginning in North America, “sub-zero temperatures are now blasting” millions of Americans following “the three historic snowstorms which buried parts of the U.S. last month,” reports weather site electroverse.net here.

Electroverse writes that “lows throughout the week will be more like January temperatures” with readings below zero for many U.S. states and “temps down into the teens are even forecast as far south as Texas.” Yesterday, 97 records toppled.

“It’s a big deal,” Electroverse writes in its headline.

Solar activity suspected

It’s not the sort of thing we are supposed to be expecting from a “warming planet”.  Some climate experts blame natural factors, like solar activity, for the cold, and that these warnings have long been known since the sun has entered a new period of calm.

Freeze watches and warnings also extend as far south as Florida. And it’s only early November. And don’t expect to see many FFF activists to show up at rallies protesting hot weather any time soon.

Polar Bear Science site here also reports that the Hudson Bay in Canada has started freezing up earlier than normal three years in a row!

Europe starting to get clobbered by snow, 2m in Alps

Meanwhile cold has also spread across Europe, though not quite as brutal as what we’ve been seeing across North America.

NEW ZEALAND EXPERIENCES FOURTH COLDEST SEPTEMBER THIS CENTURY

by Cap Allon, October 4, 2019 in Electroverse


New Zealand’s average temperature last month –for the country as a whole– was below the 1981-2010 September avg., Niwa has said in its Monthly Climate Summary.

An unusual warming of the atmosphere high above Antarctica –called a Sudden Stratospheric Warming event (SSW)– assisted in making last month the fourth coldest September in New Zealand this century.

There have only ever been two SSWs recorded in the Southern Hemisphere, previous to this years — one in September 2002 (major) and another in September 2010 (minor).

The 2002 SSW event resulted in New Zealand experiencing a significant cold outbreak in October while the 2010 event was associated with record rainfall during September.

Record Antarctic Stratospheric Warming Causes Sept. 2019 Global Temperature Update Confusion

by Roy Spencer, October 4, 2019 in WUWT


While the vast majority of our monthly global temperature updates are pretty routine, September 2019 is proving to be a unique exception. The bottom line is that there is nothing wrong with the UAH temperatures we originally reported. But what I discovered about last month is pretty unusual.

It all started when our global lower tropospheric (LT) temperature came in at an unexpectedly high +0.61 deg. C above the 1981-2010 average. I say “unexpected” because, as WeatherBell’s Joe Bastardi has pointed out, the global average surface temperature from NOAA’s CFS model had been running about 0.3 C above normal, and our numbers are usually not that different from that model product.

[By way of review, the three basic layers we compute average temperatures from the satellites are, in increasing altitude, the mid-troposphere (MT), tropopause region (TP), and lower stratosphere (LS). From these three deep layer temperatures, we compute the lower tropospheric (LT) product using a linear combination of the three main channels, LT = 1.548MT – 0.538TP +0.01LS.]

Yesterday, John Christy noticed that the Southern Hemisphere was unusually warm in our lower stratosphere (LS) temperature product, while the Northern Hemisphere was unusually cool. This led me to look at the tropical results for our mid-troposphere (MT) and ‘tropopause’ (TP) products, which in the tropics usually track each other. A scatterplot of them revealed September 2019 to be a clear outlier, that is, the TP temperature anomaly was too cool for the MT temperature anomaly.

So, John put a notice on his monthly global temperature update report, and I added a notice to the top of my monthly blog post, that we suspected maybe one of the two satellites we are currently using (NOAA-19 and Metop-B) had problems.

As it turns out, there were no problems with the data. Just an unusual regional weather event that produced an unusual global response.

RECORDS CONTINUE TO FALL ACROSS THE NW + MORE HISTORIC COLD SET TO ENGULF ALL OF NORTH AMERICA BY OCT 10

by Cap Allon, October 3, 2019 in Electroverse


This weekend will mark the final phase of a major winter storm that ravaged the NW U.S. bringing whipping winds to the Flathead Valley, feet of snow along the Continental Divide and record-breaking/challenging temps for all.

A new all-time daily record low temperature was set in Kalispell, Montana on Wednesday, October 02 as the mercury plunged into the teens across the region.

The weather station at Glacier Park International Airport recorded a low of 19F (-7.2C) at 5 AM which busted the dates previous record low of 21F (-6.1C) set back in 1999.

Great Falls, Montana registered a record-smashing 9F (-12.8C) on Tue, Oct 01, according to the NWS, which annihilated the previous daily low of 22F (-5.6C) set back in 1959.

Additionally, areas to the northwest also saw record low daily temperatures on Tuesday as both Cut Bank and Browning comfortably surpassed their previous cold records from 1950.

And further south, crossing a few state lines into California, temperatures at Sacramento Executive Airport dropped to 42F (5.6C) early Wednesday morning, surpassing the old record of 43F (6.1C) set in 1971. Meaning that in less than a week, Sacramento has now set multiple all-time record lows; on Sunday, both downtown Sacramento and the airport set record lows of 45F (7.2C) and 46F (7.8C) respectively.

Global Temperature Report: September 2019

by Anthony Watts, October 3, 2019 in WUWT


Global climate trend since Dec. 1 1978: +0.13 C per decade

September Temperatures (preliminary)

Global composite temp.: +0.61 C (+1.10 °F) above seasonal average

Northern Hemisphere.: +0.64 C (+1.15 °F) above seasonal average

Southern Hemisphere.: +0.58 C (+1.00°F) above seasonal average

Tropics.: +0.60 C (+1.08°F) above seasonal average

August Temperatures (final)

Global composite temp.: +0.38 C (+0.68 °F) above seasonal average

Northern Hemisphere.: +0.33 C (+0.59 °F) above seasonal average

Southern Hemisphere.: +0.44 C (+0.79°F) above seasonal average

Tropics.: +0.45 C (+0.81 °F) above seasonal average

Notes on data released October 3, 2019 (v6.0)

September’s globally-averaged, bulk-layer atmospheric temperature anomaly of +0.61°C (+1.10°F) represented the warmest September reading of the past 41 Septembers in our satellite record. The jump from August was substantial (+0.23°C) and ranks among the largest month-to-month changes. (Several previous jumps were greater than 0.3°C however.) The warmth was global in extent with warmest September temperatures posted for both hemispheres and the tropical belt. This month-to-month heating is possibly related, at least in part, to the tropical Pacific Ocean’s loss of heat energy to the atmosphere in the recent months as El Niño conditions declined.

2019 Arctic Ice Demise Deferred Again

by Ron Clutz, October 2, 2019 in ScienceMatters


MASIE daily results for September show 2019 early melting followed by an early stabilizing and refreezing.

Note that 2019 started the month about 800k km2 below the 12 year average (2007 through 2018 inclusive).  There was little additional loss of ice, a rise then a dip below 4 M km2, and a sharp rise ending the month.  Interestingly, 2019 matched the lowest year 2012 at the start, but ended the month well ahead of both 2012 and 2007.

The table for day 273 shows distribution of ice across the regions making up the Arctic ocean.

Summer Heatwaves? It Was Hotter In 1707!!

by P. Homewood, Sept.2, 2019 in NotaLotofPeopleKnowThat


To read the headlines in the last month or two, you would think we had been having a Mediterranean summer.

The truth is much more mundane however.

The numbers for last month’s CET are now out. August ended up at 17.1C, meaning that there have been 32 Augusts as warm or warmer. Last month was no warmer than 1801, 1842 and 1932.

Summer as a whole ranked 48th hottest, tied with 1935.

The summer of 1976 still remains top of the list, but second hottest was way back in 1826.

Indeed there have been warmer summers on 28 occasions prior to 1900. Notably, one such summer was 1666, the 18th warmest. That was, of course, the year of the Great Fire of London, which swept through London between the 2nd and 6th of September.

Temps far, far below normal across almost the entire territory of European Russia

by Robert, August 4, 2019 in IceAgeNow


We’re talking about record-breaking cold across an area almost half as big as the entire contiguous United States.

2 Aug 2019 – In a number of points in the north-east of the territory, the temperature dropped to record lows. In the capital of the Komi Republic, in Syktyvkar, it dropped to 2.7 degrees, which is 0.3 degrees lower than the previous record held since 1944.

Not only in the northern areas, the temperature also dropped to critical levels. In Voronezh the thermometers showed +7 degrees, leaving behind the previous record of +7.1 degrees in 1971.

Further south, in Saratov, the minimum temperature on the first day of August was 9.6, beating the previous record of 10.4 degrees set in 1948.

The cold also hit Azov. In Tsimlyansk, Rostov Region, on August 1 the temperature fell to 13.3 degrees. The previous record, 13.6, was noted in 1975.

On the first day of August, the average temperature across almost the entire territory of European Russia was 4-6 degrees below normal, and in the Volga region it did not reach the average long-term values ​​of 8 degrees.

Cold weather throughout the territory from the White to the Black Sea will continue for at least another week.

European Russia covers nearly 4,000,000 km2 (1,500,000 sq mi).
Together, the 48 contiguous states and Washington, D.C. occupy a combined area of 8,080,464.3 km2 (3,119,884.69 sq miles).

July 2019 Was Not the Warmest on Record

by Roy Spencer, August 2, 2019 in GlobalWarming


July 2019 was probably the 4th warmest of the last 41 years. Global “reanalysis” datasets need to start being used for monitoring of global surface temperatures. [NOTE: It turns out that the WMO, which announced July 2019 as a near-record, relies upon the ERA5 reanalysis which apparently departs substantially from the CFSv2 reanalysis, making my proposed reliance on only reanalysis data for surface temperature monitoring also subject to considerable uncertainty].

‘Hidden’ NOAA temperature data reveals that 6 of the last 9 months were below normal in the USA – and NOAA can’t even get June right

by Anthony Watts, July 30, 2019 in WUWT


A review of state-of-the-art climate data tells a different story than what NOAA tells the public.

While media outlets scream “hottest ever” for the world in June and July (it’s summer) and opportunistic climate crusaders use those headlines to push the idea of a “climate crisis” the reality is for USA is that so far most of 2019 has been below normal, temperature-wise.

Little known data from the state of the art U.S. Climate Reference Network (which never seems to make it into NOAA’s monthly “state of the climate” reports) show that for the past nine months, six of them were below normal, shown in bold below.

201810 -0.18°F
201811 -2.56°F

Lingen Cheated: Germany’s New All-Time Record High Resulted From DWD Weather Service Lousy Station Siting

by P. Gosselin, July 28, 2019 in NoTricksZone


During last week’s record-setting European heat wave, Germany’s previous record of 40.3C was impressively shattered by the measurement station located at the northwest city of Lingen, near the Dutch border, some 50 kilometers from where I live. The German DWD weather service and media loved it!

Controversial siting

Yet, controversy now swirls about the new record setting measurement since it has come to light that the measurement is fraught with some considerable siting issues.

As the photo published by T-online here shows, the station is located right near a DWD office building, is shielded from the wind by grown trees and is located not far from a public swimming pool.

Meteorologist Michael Theusner told t-online.de: “The monthly average of the daily highs in Lingen has been deviating more and more upwards from the average of the highs in Lower Saxony since 2010.” The station has become increasingly shielded and thus tends to heat up more.

Swiss veteran meteorologist Jörg Kachelmann wrote the extra heat possibly could be heating the station by up to another 3 degrees!

DWD accepts overheated reading

GLOBAL TEMPERATURE FALLING AGAIN

by Clive Best, July 27, 2019 in GWPF


The global averaged surface temperature for June 2019 was 0.62C, back down to where it was before the 2015/16 El Nino.

The global averaged surface temperature for June 2019 was 0.62C using my spherical triangulation method merging GHCNV3 with HadSST3. This is a further drop of 0.04C from May 2018. The discrepancy with GHCNV4 is however growing. V4C calculated in exactly the same way gives a June temperature of 0.75C, a rise of 0.03C,  and 0.13C warmer than V3. This difference is statistically significant.

UK Record Temperature Stays Intact

by P. Homewood, July 26, 2019 in NotaLotofPeopleKnowThat

The Met Office have been desperate to declare a new UK temperature record this week, but the weather gods said no!

The Cambridge temperature fell well short of the all time record of 38.5C set at Faversham in 2003.

They feebly claim that the Cambridge temperature is still a record for July. Climatologically July is a warmer month than August, when the Faversham record was set, so by all accounts the 2003 heatwave was more extreme than yesterday’s.

The cause of the high temperatures is very clear. Not only was hot air being drawn up from Spain, but a deep area of low pressure to the west powered up the jet stream to bring that hot air north very quickly, before the heat had a chance to dissipate.

Record High Temperatures in France: 3 Facts the Media Don’t Tell You

by Roy Spencer, July 2, 2019 in GlobalWarming


News reporting of the recent heat wave in France and other European countries was accompanied with the usual blame on humans for causing the event. For example, here’s the CBS News headline: Record-breaking heat is scorching France. Experts say climate change is to blame.

While it is possible that the human component of recent warming might have made the heat wave slightly worse, there are three facts the media routinely ignore when reporting on such “record hot” events. If these facts were to be mentioned, few people with the ability to think for themselves would conclude that our greenhouse gas emissions had much of an impact.

More Failed Predictions: May Was The Second Wettest Month In US History

by Chriss Street, June 28, 2019 in ClimateChangeDispatch


National Oceanic and Atmospheric Administration reported the month of May was the second wettest and temperatures were in the bottom-third for its 125-year US history.

The 2010 publication titled, ‘A Global Overview Of Drought and Heat-Induced Tree Mortality Reveals Emerging Climate Change Risks for Forests’, was accepted by the Obama administration as scientific evidence that climate change had made the Earth:

“…increasingly vulnerable to higher background tree mortality rates and die-off in response to future warming and drought, even in environments that are not normally considered water-limited.”

But NOAA just reported that May US precipitation totaled an average of 4.41 inches, 1.50 inches above average, and ranked second wettest in the 125-year period of record for May as well as second wettest for all months since January 1895.

The only wetter month in US history was May 2015 with 4.44 inches of precipitation.

The 37.68 inches of precipitation across the contiguous U.S. from June 2018 to May 2019 shattered the previous 1982-83 12-month period by 1.48 inches.

Near-record to record precipitation was observed from the West Coast through the central Plains and into the Great Lakes and parts of the Northeast.

As a result, severe May flooding was observed along the Arkansas, Missouri, and Mississippi rivers. Vicksburg, MS, reported ongoing flooding since mid-February.
