500 Scientists: "There is no Climate Emergency"

09/25/2019 16:40 - Posted by Tom van Leeuwen

Earlier this week, a group of "more than 500 knowledgeable and experienced scientists and professionals in climate and related fields" sent this urgent message to the United Nations declaring there is no climate emergency. They urge to review the climate models on which international policy is based, calling these models "unfit for their purpose" and "Immature".
The group invites the UN to organize together "a constructive high-level meeting between world-class scientists on both sides" on climate change.

The complete letter:

23 September 2019

Sr. António Guterres, Secretary-General, United Nations,
United Nations Headquarters,
New York, NY 10017, United States of America.

Ms. Patricia Espinosa Cantellano, Executive Secretary,
United Nations Framework Convention on Climate Change,
UNFCCC Secretariat, UN Campus, Platz der Vereinten Nationen 1,
53113 Bonn, Germany

Your Excellencies,

There is no climate emergency

A global network of more than 500 knowledgeable and experienced scientists and professionals in climate and related fields have the honor to address to Your Excellencies the attached European Climate Declaration, for which the signatories to this letter are the national ambassadors.

The general-circulation models of climate on which international policy is at present founded are unfit for their purpose. Therefore, it is cruel as well as imprudent to advocate the squandering of trillions of dollars on the basis of results from such immature models. Current climate policies pointlessly and grievously undermine the economic system, putting lives at risk in countries denied access to affordable, reliable electrical energy.

We urge you to follow a climate policy based on sound science, realistic economics and genuine concern for those harmed by costly but unnecessary attempts at mitigation.

We ask you to place the Declaration on the agenda of your imminent New York session.

We also invite you to organize with us a constructive high-level meeting between world-class scientists on both sides of the climate debate early in 2020. Such a meeting would be consistent with the historically proven principles of sound science and natural justice that both sides should be fully and fairly heard. Audiatur et altera pars!
Please let us know your thoughts on how we bring about such a momentous joint meeting.

Yours sincerely,
Professor Guus Berkhout The Netherlands
Professor Richard Lindzen USA
Professor Reynald du Berger French Canada
Professor Ingemar Nordin Sweden
Terry Dunleavy New Zealand
Jim O’Brien Irish Republic

There is no climate emergency

A global network of 500 scientists and professionals has prepared this urgent message. Climate science should be less political, while climate policies should be more scientific. Scientists should openly address the uncertainties and exaggerations in their predictions of global warming, while politicians should dispassionately count the real benefits as well as the imagined costs of adaptation to global warming, and the real costs as well as the imagined benefits of mitigation.

Natural as well as anthropogenic factors cause warming

The geological archive reveals that Earth’s climate has varied as long as the planet has existed, with natural cold and warm phases. The Little Ice Age ended as recently as 1850. Therefore, it is no surprise that we now are experiencing a period of warming.

Warming is far slower than predicted

The world has warmed at less than half the originally-predicted rate, and at less than half the rate to be expected on the basis of net anthropogenic forcing and radiative imbalance. It tells us that we are far from understanding climate change.

Climate policy relies on inadequate models

Climate models have many shortcomings and are not remotely plausible as policy tools. Moreover, they most likely exaggerate the effect of greenhouse gases such as CO₂. In addition, they ignore the fact that enriching the atmosphere with CO₂ is beneficial.

CO₂ is plant food, the basis of all life on Earth

CO₂ is not a pollutant. It is essential to all life on Earth. Photosynthesis is a blessing. More CO₂ is beneficial for nature, greening the Earth: additional CO₂ in the air has promoted growth in global plant biomass. It is also good for agriculture, increasing the yields of crops worldwide.

Global warming has not increased natural disasters

There is no statistical evidence that global warming is intensifying hurricanes, floods, droughts and such as natural disasters, or making them more frequent. However, CO₂-mitigation measures are as damaging as they are costly. For instance, wind turbines kill birds and bats, and palm-oil plantations destroy the biodiversity of the rainforests.

Climate policy must respect scientific and economic realities

There is no climate emergency. Therefore, there is no cause for panic and alarm. We strongly oppose the harmful and unrealistic net-zero CO₂ policy proposed for 2050. If better approaches emerge, we will have ample time to reflect and adapt. The aim of international policy should be to provide reliable and affordable energy at all times, and throughout the world.

Fighting the climate hysteria is time-consuming! If you think I'm on the right track and you want to support my efforts I would be more than happy to receive a small donation that will help me to maintain this site.

Thanks!

The fingerprints of the greenhouse effect

The hypothesis of "man-made climate change" tells us that the increase in the concentration of CO₂ enhances the greenhouse effect of the atmosphere and has global warming as a final result.

Since the beginning of the industrialized era around 1850, man emits relatively large amounts of CO₂ into the atmosphere through the use of fossil fuels. The consequence of these emissions is that during that period, the concentration of CO₂ in the atmosphere increased sharply from about 300 parts per million to more than 400 ppm, an increase of almost 40%. The average temperature increased in the same period more or less 1.5 °C with a small variation depending on the data source used.

Why did the warming stop?

The political reports of the IPCC are based on the hypothesis that CO₂ is the most important control knob of the Earth's temperature. The problem is that this hypothesis does not correspond at all with the empirical data available to science. Forecasts are made using models that are not capable of 'predicting' the past.

Temperature versus CO₂ – the big picture

When discussing “Climate Change” it’s good to have an understanding of how the Earth’s climate has changed in the past. That will give us a reference to decide whether the current changes are normal or not.

Global temperatures have varied a lot over the last 500 million years. Depending on the timescale used, the current temperature is either cold or hot, so when you want to know the “normal temperature” you’ll have to indicate what timescale you’re using.

Dutch Warming

In the Netherlands, the day-to-day whether depends heavily on the direction the wind is coming from. Being a small country, the wind direction is quite homogeneous for the whole country, specially on higher altitudes where the bulk of heat convection is taking place.

Due to its geographical position, midway between the icy-cold Arctic to the north, the dry and hot Sahara to the south, the Eurasian land-mass to the east and the Atlantic Ocean to the west, every wind direction comes with unique weather characteristics.

North - cold,
East - dry,
South - warm,
West - wet whether.

Satellite temperature observations

This month of January 2023, the average satellite temperature published, by Dr. Christy and Dr. Spencer (University Alabama Huntsfield) had a negative deviation, compared with the average monthly measures between 1991 and 2000.

Of course, this value does not mean much, it's definition is full of arbitrary begin and endpoints, but anyway it doesn't sound like a lot of warming has taken place over the past 30 years, and even less "catastrophic warming" we're reading about in the Mainstream Media, newspapers and TV stations.

CO₂ saturation

This graph is all you need to understand that CO₂ is not the Earth's Climate Control Knob.

On the horizontal axis, we see the Infra-red (IR) spectrum wavelengths, that is like "IR colors" were this kind of radiation visible to the human eye.
The vertical axis shows to energy flux, that is the energy emitted by the Earth, as seen from outer space.

The graph itself shows how the Earth's atmosphere filters the IR radiation emitted by the Earth's surface and the role of the various greenhouse gases in that filtering process. The green line is the filter of the Earth's atmosphere without any greenhouse gases.

Video - Who are the real climate deniers?

The climate has shown many fluctuations during the Holocene. The difference between the highest and lowest average temperature of the past 10 thousand years is about 3 °C.

Climate alarmists, led by the IPCC, are trying to deny this, and understandably so. This variation means that without human influence there was climate change as well.

This undermines their hypotheses and often their jobs depend on it.

Satellite Earth temperature February 2022

The satellite temperature departure measurement for February 2022 is exactly 0° C.

This means that Earth temperature during February 2022 was exactly the same as the average from 1991 to 2020.

Satellites are the best way to have insight into the short-term temperature variations. They measure the whole surface, independent of weather station distribution, Heat Islands, measurement failures, surface condition (land or water).

There is a step-wise increase in temperature, triggered by two very strong El Niño events (1998 and 2016.) The energy that welled up from the deep oceans established a new level in these two ocasions, where the warming paused. This is a natural phenomenon and has nothing to do with CO₂, or human activity.

Where is the Climate Emergency? It just does not exist.

Wake up and spread this information to your government!
