Catastrophic global warming is the whole point of the global warming debate! If there is no catastrophic global warming, we don't need to spend billions on "climate protection". In the past there have been thousands of global warming trends that were faster and bigger. Those weren't catastrophic.

There are an infinite amount of cooling trends in the temperature records. It all depends on the time frame one chooses. For the last ten years there is a cooling trend in the UAH temperature record, while the CO2 part in the air is steadily growing.

Another example is the longest temperature record that I know of. It shows a cooling trend of about minus -6 degrees Celsius over 550 million years:

Venus is closer to the sun and has a denser athmosphere than our earth.

The seasons of the earth aren't caused by solar variation! Here is a quote from wikipedia:

"Seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earth's axis relative to the plane of revolution."

All your temperature records are from Nasa. Nasa changes old data mostly down and doesn't explain why. The result is a warming trend that isn't in the original data. I don't believe their temperature record anymore!

I use the temperature record of the University of Alabama in Huntsville (UAH). The temperature is measured by satellites. Therefore there is no heat island effect that distorts the data.

In addition it is the only record that is confirmed by weather balloons measurements, an independent record.

This is a site, which shows the most used temperature records with its sources:

But most importantly, none of the temperature shows an alarming rise in the global temperature. Neither the speed nor the magnitude of the temperature change is unique in the climate history of the earth. On the contrary it is a normal change.

I think this work has not been published yet. The authors say that it is in preprint here:

"The atmospheric greenhouse effect, an idea that authors trace back to the traditional works of Fourier 1824, Tyndall 1861, and Arrhenius 1896, and which is still supported in global climatology, essentially describes a fictitious mechanism, in which a planetary atmosphere acts as a heat pump driven by an environment that is radiatively interacting with but radiatively equilibrated to the atmospheric system. According to the second law of thermodynamics such a planetary machine can never exist. Nevertheless, in almost all texts of global climatology and in a widespread secondary literature it is taken for granted that such mechanism is real and stands on a firm scientic foundation. In this paper the popular conjecture is analyzed and the underlying physical principles are clarified. By showing that (a) there are no common physical laws between the warming phenomenon in glass houses and the fictitious atmospheric greenhouse effects, (b) there are no calculations to determine an average surface temperature of a planet, (c) the frequently mentioned difference of 33 C is a meaningless number calculated wrongly, (d) the formulas of cavity radiation are used inappropriately, (e) the assumption of a radiative balance is unphysical, (f) thermal conductivity and friction must not be set to zero, the atmospheric greenhouse conjecture is falsified."
