Clouded Vision – A Case for Climate Reverse Engineering – Part 2

This article reveals the smoking gun of deliberate climate warming using massive aerosol deployments that manipulate cloud ratios in favor of selective arctic warming

by Dylan Jones

Low level cloud cover has an overall warming effect in the polar regions 60° – 90° N and 60° – 90° S, contrary to an overall cooling effect everywhere else. High level cloud cover has an overall warming effect at all latitudes.

In the last few decades, overall cloud cover has increased at a significantly greater rate at the North Pole than at the equator and the South Pole. This UNEVEN pattern is correlated with an UNEVEN increase in global temperatures, 1.5°C in the North Pole and 0.35°C in the South Pole over a similar time period.

It is difficult to assign this uneven shift to the role of Carbon dioxide induced warming alone.

This is because Carbon dioxide, although emitted predominantly in the Northern Hemisphere (about 50 ° N), is a gas and thus MIXES EVENLY in the atmosphere throughout all the latitudes.
Changes in cloud cover could be one of the factors that account for this pattern.

We have observed the changes in cloud type distribution and frequency that have contributed towards increased temperatures in the region 60°N to 60°S.

But what of the regions 60° – 90° N and 60° – 90° S, the polar regions?

At this stage it is very important to note that:

♦ Low level clouds, whilst having an overall cooling effect in the lower latitudes – up to 60°N and 60°S, have an overall, WARMING effect in the HIGHER latitudes.  This is in addition to the high level clouds, which have an overall warming effect at all latitudes and have been on the increase since the 1970s.

♦ It is known that 70% of the Earth`s surface is covered by clouds at any given time. However, this percentage varies according to which part of the globe is being considered.

♦ Looking at the change in Arctic cloud cover, we can see that there has been a roughly 10% increase from the period 1980 (73%) to 2005 (83%). This linear change can be seen to contrast with the effects of the Arctic oscillation.

Climate Indicators – Clouds

In the Arctic regions, 60° – 90° N, the IPCC showed in 2001 that average year round cloud cover was about 70% whilst, curiously, at the South Pole it was about 3%.

How might this difference in actual cloud cover between the North Pole (70%) and the South Pole (3%) correlate with the record for temperature change by latitude?

 Robert C. Balling, Jr. gives a graph relevant to comparing a model prediction with the actual record.

It is given in his article, “Observational Surface Temperature Records versus Model Prediction,” which is published in Shattered Consensus: The True State of Global Warming (page 53). A facsimile of Balling’s graph is shown above.

The Cloud Blanket Effect Compared to the Greenhouse Effect in the Atmosphere

At the North Pole temperatures have increased 1.5 °C whilst at the South Pole they have increased 0.35 °C.

Aerosols may drive a significant portion of global warming.

“The Arctic region has been warming more than anywhere else on earth over the past twenty years. Eastman and Warren (2010) have shown that this warming has been enhanced by cloud changes. They show an increasing trend in the Arctic total cloud cover and a positive correlation between Arctic cloud cover and surface air temperature in autumn, winter and spring.

Surface air temperature has been observed to increase at a rate of 0.5 C per decade by the International Arctic Buoy Programme (Rigor et al.2000) and at a rate of 0.8 C per decade according to the National Centers for Environmental Prediction-National Center for Atmospheric Research (NCEP-NCAR) reanalysis (Kalnay et al. 1996). Given the relationship between clouds and both sea ice and surface temperature, it is likely that decadal trends in cloud cover are present and are a factor in climate change.”

If Arctic temperatures have increased by 1.5°C, a rate greater than at the equator and at the South pole, then it is difficult to assign this uneven shift to the role of Carbon dioxide induced warming alone.

This is because Carbon dioxide, although emitted predominantly in the Northern Hemisphere (about 50 ° N), is a gas and thus MIXES EVENLY in the atmosphere throughout all the latitudes.

This can be seen in this video showing surface measurements of Co2 varying over different latitudes from 1979 to 2006. (Video)

If Co2 was well mixed in the atmosphere as expected, we should have seen a similar temperature increase in the Antarctic but we have not

Antarctic temperature has increased by 0.35 °C. If anything this is less than the increase in the tropic region.

It should be clear by now that one of the candidates responsible for the UNEVEN distribution of global temperature increase is cloud cover.

The graph of “Zonal Mean” above, shows the variation by latitude showing that it is a northern hemisphere and mainly Arctic phenomenon.

Global Warming is Not Global

Contrast the above with this:

Faster atmospheric warming in subtropics pushes jet streams toward poles

What happened to the poles? We are rarely shown how much faster the warming of the North Pole is in comparison to everywhere else.
In addition to the warming effect of tropospheric clouds (both cumulus and cirrus) over the Arctic, we also have polar stratospheric clouds.

“Polar Stratospheric Clouds (PSCs) are clouds that form in the lower stratosphere under low temperatures found in high latitude polar regions. They warm the troposphere and the surface of the Earth by trapping outgoing long wave radiation. The albedo effect is minimal because they are most likely to occur in polar night regions. So there is a net warming greater than the effect of greenhouse gases.

The formation of PSCs may be linked to tropospheric methane concentrations because oxidation of methane in the troposphere is a significant source of stratospheric water vapour.”

Sloan and Pollard: Polar stratospheric clouds: A high latitude warming mechanism in an ancient greenhouse world (PDF)

Polar Stratospheric Clouds (PSCs), or Nacreous clouds form once stratospheric temperatures decrease to -78°C. In addition to trapping outgoing long wave radiation and warming the troposphere, these clouds also attack ozone molecules leading to an increase in the ozone hole.

Since 1979 the Arctic stratosphere has cooled, resulting in increased PSCs and loss of ozone.

Peter Sinclair establishes that the Sun could NOT be responsible for the observed global warming of the last thirty years. This, according to Sinclair, is for the following reasons:

  • “There has been no trend detected in solar activity that correlates with the warming of the last thirty years.”
  • “If the Sun were warming the atmosphere from space, there would be a uniform warming pattern all the way down. What we see, however, is warming of the Troposphere, the lower part of the atmosphere, whilst the region above that, the Stratosphere is cooling.”
  • “The planet is warming at the same rate at night as during the day.”
  • “There is more warming in winter than in summer.”
  • “There is more warming at the poles than at the equator.”

“This pattern is the thermodynamic fingerprint, the smoking gun, the DNA evidence, of human caused greenhouse warming.”

Whilst points 1 – 4 are correct, point 5 is not, not entirely. It fails to take the disproportionate temperature increases in the Arctic into consideration.

This “thermodynamic fingerprint” this “smoking gun”, this “DNA evidence” points rather towards the changes in cloud type distribution and frequency that have been observed over the last 30 years or so.
