DESCRIPTION
Does the climate change because solar and cosmic rays activities are changing?TRANSCRIPT

Remember:
1972
In 1972 the Club of Rome published its landmark report, Limits to Growth, which dramatically predicted the inevitable collapse of civilization unless economic growth was halted immediately
The only solution to avoid this horrible outcome? Strict government-imposed controls on just about everything and a restriction of average industrial output per capita at about the 1975 level.

The Little Ice Age (LIA)
From 1400 -1600(?) to 1850(?) At least 1°C colder Probably global, not only NH Not uniform
(time/regional)

Be10 = solar activity proxy (ice core)

C14 = solar activity proxy (tree rings)
Red + Green = Be10

Solar wind

Solar wind speed

Galactic Cosmic Rays (GCR)
GCR =electronsprotons (90%)helium (9%)other nuclei(all elements)
13
GCR modulation by solar activity
Active sun > many sun spots > strong solar wind > blown away GCRs > less Be10 + C14

GCR and clouds

GCR >>> clouds
Low clouds ( < 3.2 km)
Middle clouds ( 3.2- 6.5 km)
High clouds ( > 6.5 km)

Radiative heating
IPPC: CO2 emissions = + 1.66 W/m2Palle: warming due to the reduction in cloud cover 1993 to 2001 = + 7.5 W/m2
26
IPCC consensus forcingsLOSU = level of scientific understanding
high
low
( Change relative to pre-industrial 1750 situation)
27
IPCC concensus ignored climate forcings
Cosmic rays UV increase (10 times TSI increase) Ocean emissivity (positive solar feedback) Albedo decrease (greening earth) ????
IPCC climate sensitivity Cs = dT/Σforcings = 0.75K/(Wm-2) probably much too high i.e. wrong!

Decreasing AOT (atmospheric optical thickness)
AOT is a measure of the atmosphere’s turpitude at a special wavelength. AOT = [0…1]

Prof. S. Akasufo (director of the Arctic International Research Center)
There is so far no definitive proof that most of the “observed” warming is due to the (man made) greenhouse effect (March 2007)

Prof. R. Lindzen, MIT
Die heutige Unruhe hat ihre Ursachen zum grössten Teil in mangelnden Kenntnissen, was bei Wetter und Klima normal ist…
Sämtliche Untersuchungen zu den Auswirkungen des Klimawandels gehen von einer langen Kette von Voraussetzungen aus, und es besteht nur eine sehr geringe Wahrscheinlichkeit, dass die Folgen dieser Kette richtig vorausgesagt werden [Cicerone, Juni 07]
