Anthony Watts reports on the dearth of sunspots that will lead to a significant period of global cooling:
I’m writing this after doing an exhaustive search to see what sort of solar activity has occurred lately, and I find there is little to report. With the exception of the briefly increased solar wind from a coronal hole, there is almost no significant solar activity.Folks, cold kills. Warmth gives life.
The sun has gone quiet. Really quiet.
It is normal for our sun to have quiet periods between solar cycles, but we’ve seen months and months of next to nothing, and the start of Solar cycle 24 seems to have materialized (as first reported here) then abruptly disappeared. The reverse polarity sunspot that signaled the start of cycle 24 on January 4th, dissolved within two days after that.
...Given the current quietness of the sun and it’s magnetic field, combined with the late start to cycle 24 with even possibly a false start, it appears that the sun has slowed it’s internal dynamo to a similar level such as was seen during the Dalton Minimum. One of the things about the Dalton Minimum was that it started with a skipped solar cycle, which also coincided with a very long solar cycle 4 from 1784-1799. The longer our current cycle 23 lasts before we see a true ramp up of cycle 24, the greater chance it seems then that cycle 24 will be a low one.
No wonder there is so much talk recently about global cooling. I certainly hope that’s wrong, because a Dalton type solar minimum would be very bad for our world economy and agriculture. NASA GISS published a release back in 2003 that agrees with the commonly accepted idea that long period trends in solar activity do affect our climate by changing the Total Solar Irradiance (TSI).
Some say it is no coincidence that 2008 has seen a drop in global temperature as indicated by several respected temperature indexes compared to 2007, and that our sun is also quiet and still not kick starting its internal magentic dynamo.
The science underpinning predictions of a downturn in global temperatures is profoundly more sound than that supporting a catastrophic upturn. If you truly believe in science - we understand exactly what reduced solar activity means - then you should at least consider the possibility of 50 years of cooling temperatures and the negative global consequences that will bring.
