Global Agricultural Boom: A million Thanks To Climate Change

“Global agricultural production suffered only during cold periods, including the Little Ice Age, which ended around the late 18th or early 19th century.

Since the 1800s, the earth has been warming — returning to levels ideal for crop production. It is remarkable that the mainstream media can claim that temperatures are killing crops when they have actually contributed to exponential growth of crop yields.”

A rather unwelcome message for the anti-CO2, misanthropic environmental movement.

As the report concludes: ‘Both global warming and carbon dioxide have benefitted plant growth, and both are important contributors to the success of modern civilization.’

Global cereal (grain) production has reached record levels in 2017, says The GWPF.

Credit for the increase usually goes to agrochemicals and other advanced agricultural technology. However, there are two other key contributors — carbon dioxide and climate change.

World cereal production for 2017 is projected to reach 2,613.3 million tons, 5.8 million tons above 2016’s level and nearly one-fourth higher than 2008’s. Despite population growth, production per capita rose 13 percent over the last decade, from 0.31 to 0.35 tons per person.

David Viner’s Thing Of The Past Comes Back To Haunt Him (Again!)


Bioscience article is academic rape: an assertion of power and intimidation

“Blasphemy is what an old dogma screams at a new truth.” — Robert G. Ingersoll

polarbearscience

Characterizing a professional, respected scientist as an unqualified vengeful opinion writer is the same kind of power attack as rape. It’s meant to humiliate and intimidate.

Amstup

I said this as part of a response to a comment at WUWT late yesterday (copied in full below). The picture above shows Steven Amstrup holding polar bear cubs against their will — not for any scientific purpose, just for a photo that shows he can.

Also yesterday, Tom Fuller at ClimateScepticism wrote a hard-hitting critique of the Bioscience article that similarly noted the sexist nature of this harassment and the fact that this is the way Michael Mann and his colleagues behave toward female scientists who cross them or their supporters. He concludes:

“The purpose of these papers is not to communicate.

It is to excommunicate.”

As I said when this paper first came out, this response is all about my reasoned and…

103 Year Record Cold Low For New York City Set ❄️

Nothing to see here…moving right along.

The rules are pretty straightforward:

Cold = Weather
Hot = Climate

Watts Up With That?

Added: 11/11 8:30AM PST See update below. Records were set over the past two days at Central Park, but the 144 Year old record still stands.


Dr. Ryan Maue has been tracking the forecasts for the Northeast, and the result is…ah, chilling. Maue says the “polar vortex” is responsible for the exceptionally cold and dry air invading the Northeast USA.

He goes on to say that the all time record for New York City of 22°F forecast by morning in NYC would be coldest, earliest temperature on record.

The previous earliest record of reaching 22°F was Nov 13, 1873. The 21°F expected for NYC would be the coldest in 144 years. Further…

Climatic Irony Found in An Old National Geographic Magazine

“THAT earth’s climate changes, and even now maybe changing quite rapidly, is widely recognized. The questions facing worried experts: are we warming the atmosphere of our planet irreversibly with our industry, automobiles, and land clearing practices? What sort of weather will our children and our grandchildren know? On the answers may rest the fate of nations and millions of people.”

SOUND like the all too familiar talking points of a circa 2017 warming alarmist?

NOT quite! The (edited) paragraph was from 1976, printed in NatGeo during the perceived man-made “global cooling” apocalypse.

SAME fears, different scare!

Watts Up With That?

Guest essay by Doug Ferguson

Having moved from Minnesota to Alaska this past summer, we have been making the rounds of thrift shops, stores and other venues to restock our home with things we left behind to reduce our moving costs.

Before heading out to one of our recent forays, I caught up on the news on the well known climate blog, “Watts Up With That” and read the 10/39/17 article, How Google and MSM Use “Fact Checkers” to Flood Us with Fake Claims by Leo Goldstein. You should read it. The link is here

The main example was Time magazine, but it made me think of another publication that has more subtly switched gears over the past 40 years or so to maintain the sense of impending climate doom. This is the venerable National Geographic, which currently is in full global warming alarm mode.

Therefore it was with great…

1970’s Climate Hysteria : Global Cooling – The Coming Ice Age

Time and GC.jpg

DEEP within human nature there are certain types of people who yearn for catastrophe, they yearn to have significance in their lives believing that theirs is the time when the chickens are coming home to roost and everything is going to go tits up.

THE biggest selling environmental books in history, predict the mass destruction of the planet. Rachel Carson’s 1962 international bestseller “Silent Spring” predicted mass cancer from plant pesticides and DDT. Paul Ehrlich’s “The Population Bomb” 1968, argued on malthusian lines that population explosion would mean mass starvation around the world. People buy this stuff. They lap it up and books like this sell in droves, in a way that more reasonable books that say “hang on, lets look at the facts”, don’t.

12 New Scientific Papers: Oceans Cooling Globally As Glaciers Thicken

Antartica Global Cooling.jpg

“Contrary to expectations, climate scientists continue to report that large regions of the Earth have not been warming in recent decades.”

INTERESTING to see how the warmist community will spin the “science” from these latest inconvenient findings that contradict IPCC climate model predictions and the endless Hottest Year Evah PR claims.

NO doubt, Climate Crisis Inc … and the UN IPCC won’t go near it. And don’t expect to see empirical evidence of globally cooling oceans and thickening glaciers gleefully reported on CNN, BBC or ABC Australia. Any climate news that doesn’t fit the human-caused warming narrative is expressly ignored by the #FakeNews mainstream media, using their favoured and most effective propaganda weapon – confirmation bias.

12 New Papers: North Atlantic, Pacific, And Southern Oceans Are Cooling As Glaciers Thicken, Gain Mass

Holocene-Cooling-North-Atlantic-Duchez-2016.jpg

Graph Source Duchez et al., 2016

Contrary to expectations, climate scientists continue to report that large regions of the Earth have not been warming in recent decades.

According to Dieng et al. (2017), for example, the global oceans underwent a slowdown, a pause, or even a slight cooling trend during 2003 to 2013.  This  undermines expectations from climate models which presume the increase in radiative forcing from human CO2 emissions should substantially increase ocean temperatures.

The authors indicate that the recent trends in ocean temperatures “may just reflect a 60-year natural cycle“, the AMO (Atlantic Multidecadal Oscillation), and not follow radiative forcing trends.

Dieng et al., 2017    We investigate the global mean and regional change of sea surface and land surface temperature over 2003–2013, using a large number of different data sets, and compare with changes observed over the past few decades (starting in 1950). … While confirming cooling of eastern tropical Pacific during the last decade as reported in several recent studies, our results show that the reduced rate of change of the 2003–2013 time span is a global phenomenon. GMST short-term trends since 1950 computed over successive 11-year windows with 1-year overlap show important decadal variability that highly correlates with 11-year trends of the Atlantic Multidecadal Oscillation indexThe GMST 11-year trend distribution is well fitted by a Gaussian function, confirming an unforced origin related to internal climate variability.

We evaluate the time derivative of full-depth ocean heat content to determine the planetary energy imbalance with different approaches: in situ measurements, ocean reanalysis and global sea level budget.  For 2003–2013, it amounts to 0.5 +/− 0.1 W m−2, 0.68 +/− 0.1 W m−2 and 0.65 +/− 0.1 W m−2, respectively for the three approaches.    Although the uncertainty is quite large because of considerable errors in the climate sensitivity parameter, we find no evidence of decrease in net radiative forcing in the recent years, but rather an increase compared to the previous decades.
We can note that the correlation between GMST [global mean surface temperature] trends and AMO trends is quite high. It amounts 0.88 over the whole time span. At the beginning of the record, the correlation with PDO trends is also high (equal to 0.8) but breaks down after the mid-1980s.  The GMST and AMO trends shown in Figure 6 show a low in the 1960s and high in the 1990s, suggestive of a 60-year oscillation, as reported for the global mean sea level by Chambers et al. (2012). Thus the observed temporal evolution of the GMST [global mean surface temperature] trends may just reflect a 60-year natural cycle driven by the AMO.

Subpolar North Atlantic Cooling Rapidly Since 2005

According to Piecuch et al. (2017) there has been no net warming of the North Atlantic Ocean in the last quarter century.  The warming that occurred in the 10 years from 1994-2004 has been completely negated by an even more pronounced cooling trend since 2005.   The predominant (87%) cause of the warming was determined to be of the same natural (non-anthropogenic) origin as the subsequent cooling: advection, the movement/circulation of heat via internal processes.   In fact, human CO2 emissions are never mentioned as even contributing to the the 1994-2004 warming.

Piecuch et al., 2017    The subpolar North Atlantic (SPNA) is subject to strong decadal variability, with implications for surface climate and its predictability. In 2004–2005, SPNA decadal upper ocean and sea-surface temperature trends reversed from warming during 1994–2004 to cooling over 2005–2015. … Over the last two decades, the SPNA has undergone a pronounced climate shift. Decadal OHC and SST trends reversed sign around 2004–2005, with a strong warming seen during 1994–2004 and marked cooling observed over 2005–2015. These trend reversals were pronounced (> 0.1 °C yr−1 in magnitude) in the northeastern North Atlantic (south and west of Iceland) and in the Labrador Sea. … To identify basic processes controlling SPNA thermal variations, we diagnose the SPNA heat budget using ECCOv4. Changes in the heat content of an oceanic control volume can be caused by convergences and divergences of advective, diffusive, and surface heat fluxes within the control volume.  [Advective heat convergence] explains 87% of the total [ocean heat content] variance, the former [warming] showing similar decadal behavior to the latter [cooling], increasing over 1994–2004, and decreasing over 2005–2015. … These results demonstrate that the recent SPNA decadal trend reversal was mostly owing to advective convergences by ocean circulation … decadal variability during 1993–2015 is in largest part related to advection by horizontal gyres.

North-Atlantic-Cooling-OHC-Piecuch-2017.jpg

Yeager and Robson (2017) also point out that, like it did from the 1960s to 1980s, the North Atlantic “has again been cooling”, a trend which they and others expect to continue.   Sea surface temperatures are no warmer today than they were in the 1950s.

Yeager and Robson, 2017    [W]hile the late twentieth century Atlantic was dominated by NAO-driven THC [thermohaline circulation] variability, other mechanisms may dominate in other time periods. … More recently, the SPNA [sub polar North Atlantic] upper ocean has again been cooling, which is also thought to be related to a slowdown in the THC. A continued near-term cooling of the SPNA has been forecast by a number of prediction systems, with implications for pan-Atlantic climate.

The Southern Ocean Has Been Cooling Since The 1970s, Contrary To Models

Latif et al., 2017    The Southern Ocean featured some remarkable changes during the recent decades. For example, large parts of the Southern Ocean, despite rapidly rising atmospheric greenhouse gas concentrations, depicted a surface cooling since the 1970s, whereas most of the planet has warmed considerably. In contrast, climate models generally simulate Southern Ocean surface warming when driven with observed historical radiative forcing. The mechanisms behind the surface cooling and other prominent changes in the Southern Ocean sector climate during the recent decades, such as expanding sea ice extent, abyssal warming, and CO2 uptake, are still under debate. Observational coverage is sparse, and records are short but rapidly growing, making the Southern Ocean climate system one of the least explored. It is thus difficult to separate current trends from underlying decadal to centennial scale variability.
Turney et al., 2017    Occupying about 14% of the world’s surface, the Southern Ocean plays a fundamental role in ocean and atmosphere circulation, carbon cycling and Antarctic ice-sheet dynamics. … As a result of anomalies in the overlying wind, the surrounding waters are strongly influenced by variations in northward Ekman transport of cold fresh subantarctic surface water and anomalous fluxes of sensible and latent heat at the atmosphere–ocean interface. This has produced a cooling trend since 1979.
