Tidskriften Nature accepterade nyligen den här rapporten om långsiktiga svängningar av solens magnetfält.

Det kommer alltså att bli kallare med start från och med nästa år.

Det är ju en bra nyhet att det finns chans att temperaturökningen pga. CO2-utsläpp kan dämpas under de kommande 30 åren. Då finns möjlighet att minska CO2-utsläppen genom att i lugn och ro implementera andra energikällor än de fossila (olja, kol och gas) samtidigt som vi får hjälp av solen att hålla nere temperaturen.
På så vis kan mänskligheten stå väl rustad om 30 år när solen börjar värma lite mera igen.

Men den artikeln har fått kritik. En del vill ha den indragen. De menar att den innehåller grova fel:

A high profile scientific journal is investigating how it came to publish a study suggesting that global warming is down to natural solar cycles. The paper was criticised by scientists for containing “very basic errors” about how Earth moves around the sun.
Ken Rice of the University of Edinburgh, UK, criticised the paper for an “elementary” mistake about celestial mechanics. “It’s well known that the sun moves around the barycentre of the solar system due to the influence of the other solar system bodies, mainly Jupiter,” he says. “This does not mean, as the paper is claiming, that this then leads to changes in the distance between the sun and the Earth.”
“The claim that we will see warming in the coming centuries because the sun will move closer to the Earth as it moves around the solar system barycentre is very simply wrong,” adds Rice. He is urging the journal to withdraw the paper, and says it is embarrassing it was published.
Gavin Schmidt of the NASA Goddard Institute for Space Studies says the paper contains egregious errors. “The sun-Earth distance does not vary with the motion of the sun-Earth system around the barycentre of the sun-Jupiter system, nor the sun-galactic centre system or any other purely mathematical reference point,” he says. He says the journal must retract the paper if it wants to retain any credibility.
Scientific Reports says it has begun an “established process” to investigate the paper it has published. “This process is ongoing and we cannot comment further at this stage,” a spokesperson said.
