“Dominating Factor”…Leading Warmist Climatologist Concedes Natural Oceanic Cycles Directly Related To Troposphere Temperature

oceanRenowned climate scientist Prof. Mojib Latif used to often appear on television, radio and speeches all over Germany to spread the word of an impending human-made climate catastrophe.

One of the highlights of Latif’s many appearances was the CO2 “fingerprint” in the atmosphere, which according to Latif is supposed to confirm the greenhouse effect. Up in the stratosphere it is supposed to cool because heat would be trapped by CO2 in the troposphere below. This of course always impressed his gullible audiences.

Profound reversal

However, it now appears that the distinguished German scientist is now changing his mind profoundly. In a recent press release he and his fellow co-scientists in Kiel, Germany, conceded that the cooling is likely more a part of the 60-year PDO ocean cycle.

What follows is the press release from the Kiel-based Geomar research institute dated 26 July 2016:

Middle atmosphere in sync with the ocean

26 July 2016/Kiel. In the late 20th century scientists observed a cooling at the transition between the troposphere and stratosphere at an altitude of about 15 kilometers. They believed this development in the so-called tropopause was caused by human influences. Climate scientists from Kiel and Bergen (Norway) have now published a study in the international journal Scientific Reports showing that the cooling could also be part of a natural decadal variation which is controlled by the water temperature of the Pacific.

Water plays a major role for our planet not only in its liquid form at the surface. In the atmosphere too, it considerably affects our lives as well as weather and climate. Clouds and rainfall are one example. Water vapor, the gaseous form of water, also plays a prominent role on Earth. It is the most important greenhouse gas in the atmosphere, without it the Earth would be a frozen planet. For climate variations, water vapor is particularly important in the stratosphere at altitudes between 15 and 50 kilometers. How much of the gas actually reaches the stratosphere mainly depends on the temperature at the transition between the lowest atmospheric layer, the troposphere, and the overlying stratosphere. This boundary layer is called the tropopause.

Now scientists of the GEOMAR Helmholtz Centre for Ocean Research Kiel, together with a colleague from Bergen (Norway), were able to demonstrate for the first time that natural fluctuations in water temperatures of the Pacific – which occur on decadal timescales – are directly related to the temperature of the tropical tropopause. “It has long been thought that human influences already affected the tropopause. However, it seems that natural variability is still the dominating factor,” says Dr. Wuke Wang from GEOMAR, lead author of the study just published in the international journal Scientific Reports.
