Uusi tutkimus: Aurinko, ei ihminen, aiheutti lämpenemisen

Vasta "Energy & Environment" -lehdessä julkaistu saksalaistutkimus väittää auringon erityisen voimakkaan toiminnan aiheuttaneen lämpenemisen 1950 - 2000, vuoden 2000 jälkeen ei lämpenemistä ole havaittu.


EIKE


Tätä tukee myös Oulun yliopistossa 2004 tehty tutkimus, joskin siinä vielä oletettiin antropogeenisen (ihmisen) toiminnan olleen pääasiallinen tekijä lämpenemisessä.

"In contrast to Professor Solanki’s conclusion that Man was nevertheless the main cause of global warming since 1950, Dr. Lüdecke’s research shows that the Sun is the real culprit.

The new analysis indicates that changes in the Sun’s output of radiation, which depends upon anomalies in its magnetic field that show up as sunspots, are what really drives temperature changes here on Earth.

Dr. Lüdecke said: “The Sun is still recovering from the Maunder Minimum, the 70-year period from 1645-1715 when there were hardly any sunspots. It was less active then than during any similar period over the past 11,400 years. It was then that the Hudson in New York and the Thames in London used to freeze over in the winter.

“It is the unprecedentedly rapid recovery of the Sun’s activity over the past 300 years – far stronger than anyone had previously suspected – that has been the chief driver of global warming in recent decades. We have very little to do with it.”

Dr. Lüdecke’s analysis of the 200-year record of monthly temperatures measured by thermometers at five northern-hemisphere stations shows the Earth cooled almost as much in the 19th century as it warmed in the 20th"
