Hundreds Of #Scientists Petitioning Against #Climate #Alarmism Goes Global

Climate Change Hoax Alert

A petition being submitted by hundreds of independent climate scientists and professionals from numerous countries to heads of the European Council, Commission and Parliament declares “There is No Climate Emergency.”

Briefly summarized, the request for consideration conveys five urgent messages:

  • Climate change is real and has been occurring with nature-driven cold and warm cycles for as long as the planet has existed.
  • There should be no surprise that the Earth has been warming through natural causes since the last Little Ice Age ended around 1870. Actual temperature increases, however, are far less than predicted by theoretical climate models.
  • There is no real evidence that anthropogenic (human-caused) CO2 emissions are a major or dangerous warming influence. They instead offer great benefits to agriculture, forestry and photosynthesis that is the basis for life.
  • There is also no scientific evidence that increasing CO2 levels are causing more natural disasters. However, CO2-reduction measures do have devastating impacts on wildlife (e.g. wind turbines), land use (e.g. forest clearance), and vital energy systems.
  • Energy policies must be based on scientific and economic realities — not upon a harmful and unrealistic “2050-carbon-neutral policy” driven by unfounded climate alarm.

The petition concludes by recommending the recognition of clear difference in policies addressing the Earth’s environment through good stewardship versus Earth’s climate, the latter of which “is largely caused by a complex combination of natural phenomena we cannot control.”

This recent petition to EU leaders signed by approximately 100 Italian scientists from many prominent organizations urges recognition of the same basic realities.

The Italian petition calls attention to the fact that the planet has previously been warmer than the present period, despite lower atmospheric CO2 concentrations. Warming periods have been repeated about every thousand years, including “the well-known Medieval Warm Period, the Hot Roman Period, and generally warm periods during the Optimal Holocene period.”

Most recent climate warming observed since 1850 followed the Little Ice Age – the coldest period of the last 10,000 years. “Since then, solar activity, following its [previous cooling-influence] millennial cycle, has increased by heating the Earth’s surface.”

The notification advises that climate, “the most complex system on our planet,” needs to be addressed with scientific methods that are “adequate and consistent with its level of complexity.”

This system “is not sufficiently understood. And while CO2 is indisputably a greenhouse gas, “according to [UN Intergovernmental Panel on Climate Change] IPCC itself, the climate sensitivity to its increase in the atmosphere is still extremely uncertain.”

The petition states that “In any case, many recent studies based on experimental data estimate that the climate sensitivity to CO2 is considerably lower than estimated by the IPCC models.” Accordingly, all evidence suggests that such models “overestimate the anthropic [human] contribution and underestimate the natural climatic variability, especially that induced by the sun, the moon, and ocean oscillations.”

Likewise, alarmist media claims that extreme weather events, such as hurricanes and cyclones, are increasing in frequency are entirely inaccurate and typically far more directly tied to natural ocean oscillation cycles.

Again, the Italian signatories from numerous universities and research organizations take strong issue against “deplorable propaganda” claiming that carbon dioxide is a pollutant rather than a molecule that is indispensable to life on our planet.

Accordingly, given “the crucial importance that fossil fuels have for the energy supply of humanity,” the petitioners urge that the EU should not adopt economically burdensome and unwarranted CO2 reduction policies under “the illusory pretense of governing the climate.”

The petitioners also emphasize that while credible facts must be based upon scientific methods, not determined by numbers of supporting theorists, there is no alleged “consensus” among specialist in many and varied climate disciplines suggesting that human-influenced climate change presents an imminent danger. They point out that many thousands of scientists have previously expressed dissent with alarmist ant- fossil energy conjecture.

More than 31,000 American scientists from diverse climate-related disciplines signed a Global Warming Petition Project rejecting limits on greenhouse gas emissions attached to the 1977 Kyoto Protocol and similar proposals. The list of signatories included 9,021 Ph.D.s, 6,961 at the master’s level, 2,240 medical doctors, and 12,850 carrying a bachelor of science or equivalent academic degree.

A 12-page petition attachment was introduced with a cover letter issued by Fredrick Seitz, a past president of the National Academy of Sciences and former president of Rockefeller University. It read, in part:

“This treaty is, in our opinion, based upon flawed ideas. Research data on climate change do not show that human use of hydrocarbons is harmful. To the contrary, there is good evidence that increased atmospheric carbon dioxide is environmentally helpful.”

The letter added, “The proposed agreement would have very negative effects upon the technology of nations around the world, especially those that are currently attempting to lift from poverty and provide opportunities to over 4 billion people in technologically undeveloped countries.”

Gratefully, an American Congress at that time listened to that sage advice and unanimously agreed. We can only fervently hope that more current legislators will continue to be equally wise.

July 2019 Was Not the Warmest on Record

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].

We are now seeing news reports (e.g. CNN, BBC, Reuters) that July 2019 was the hottest month on record for global average surface air temperatures.

One would think that the very best data would be used to make this assessment. After all, it comes from official government sources (such as NOAA, and the World Meteorological Organization [WMO]).

But current official pronouncements of global temperature records come from a fairly limited and error-prone array of thermometers which were never intended to measure global temperature trends. The global surface thermometer network has three major problems when it comes to getting global-average temperatures:

(1) The urban heat island (UHI) effect has caused a gradual warming of most land thermometer sites due to encroachment of buildings, parking lots, air conditioning units, vehicles, etc. These effects are localized, not indicative of most of the global land surface (which remains most rural), and not caused by increasing carbon dioxide in the atmosphere. Because UHI warming “looks like” global warming, it is difficult to remove from the data. In fact, NOAA’s efforts to make UHI-contaminated data look like rural data seems to have had the opposite effect. The best strategy would be to simply use only the best (most rural) sited thermometers. This is currently not done.

(2) Ocean temperatures are notoriously uncertain due to changing temperature measurement technologies (canvas buckets thrown overboard to get a sea surface temperature sample long ago, ship engine water intake temperatures more recently, buoys, satellite measurements only since about 1983, etc.)

(3) Both land and ocean temperatures are notoriously incomplete geographically. How does one estimate temperatures in a 1 million square mile area where no measurements exist?

There’s a better way.

A more complete picture: Global Reanalysis datasets

(If you want to ignore my explanation of why reanalysis estimates of monthly global temperatures should be trusted over official government pronouncements, skip to the next section.)

Various weather forecast centers around the world have experts who take a wide variety of data from many sources and figure out which ones have information about the weather and which ones don’t.

But, how can they know the difference? Because good data produce good weather forecasts; bad data don’t.

The data sources include surface thermometers, buoys, and ships (as do the “official” global temperature calculations), but they also add in weather balloons, commercial aircraft data, and a wide variety of satellite data sources.

Why would one use non-surface data to get better surface temperature measurements? Since surface weather affects weather conditions higher in the atmosphere (and vice versa), one can get a better estimate of global average surface temperature if you have satellite measurements of upper air temperatures on a global basis and in regions where no surface data exist. Knowing whether there is a warm or cold airmass there from satellite data is better than knowing nothing at all.

Furthermore, weather systems move. And this is the beauty of reanalysis datasets: Because all of the various data sources have been thoroughly researched to see what mixture of them provide the best weather forecasts

(including adjustments for possible instrumental biases and drifts over time), we know that the physical consistency of the various data inputs was also optimized.

Part of this process is making forecasts to get “data” where no data exists. Because weather systems continuously move around the world, the equations of motion, thermodynamics, and moisture can be used to estimate temperatures where no data exists by doing a “physics extrapolation” using data observed on one day in one area, then watching how those atmospheric characteristics are carried into an area with no data on the next day. This is how we knew there were going to be some exceeding hot days in France recently: a hot Saharan air layer was forecast to move from the Sahara desert into western Europe.

This kind of physics-based extrapolation (which is what weather forecasting is) is much more realistic than (for example) using land surface temperatures in July around the Arctic Ocean to simply guess temperatures out over the cold ocean water and ice where summer temperatures seldom rise much above freezing. This is actually one of the questionable techniques used (by NASA GISS) to get temperature estimates where no data exists.

If you think the reanalysis technique sounds suspect, once again I point out it is used for your daily weather forecast. We like to make fun of how poor some weather forecasts can be, but the objective evidence is that forecasts out 2-3 days are pretty accurate, and continue to improve over time.
