Quantitatively, the recurrent multidecadal internal variability, often underestimated in attribution studies, accounts for 40% of the observed recent 50-y warming trend.
He suggest ocean cycles account for 40% of the 50 year warming trend. The other 60% a presume is antrhopogenic GHG emissions?
Many of the other papers have dead links. Also just because we know the sun or volcanoes have played a role in past warming and cooling, doesn't dismiss the theory that man made co2 may be the primary driver of the current warming.
Interesting video. You can ignore the winter comments but there is a relation between sun and climate.
They talk about Europe mostly.
"Its too complex" to explain says one scientist but mentions the Jet Stream changes and blocking in the Atlantic..
One guy says just because Europe may have extreme cold and snowy winters, it still means elsewhere will be much warmer and that will average as no change in global trends
Another says we have industrial age, human activity and all the gases being pumped into atmosphere that will be competing with a cooling sun so we don't have a history to go off of for consequences..
The solar cycle is like a pendulum, swinging back and forth between periods of high and low sunspot number every 11 years. These data from NOAA show that the pendulum is swinging toward low sunspot numbers even faster than expected. (The red line is the forecast; black dots are actual measurements.). Given the current progression, forecasters expect the cycle to bottom out with a deep Solar Minimum in 2019-2020.
Solar Minimum is widely misunderstood. Many people think it brings a period of dull quiet. In fact, space weather changes in interesting ways. For instance, as the extreme ultraviolet output of the sun decreases, the upper atmosphere of Earth cools and collapses. This allows space junk to accumulate around our planet. Also, the heliosphere shrinks, bringing interstellar space closer to Earth; galactic cosmic rays penetrate the inner solar system and our atmosphere with relative ease. (More on this below.) Meanwhile, geomagnetic storms and auroras will continue–caused mainly by solar wind streams instead of CMEs. Indeed, Solar Minimum is coming, but it won’t be dull.
Past 17yrs: Source . I can't get over the max peak of this cycle. It's so low, lower than NOAA had thought. No peaking now as we're in the down part of the cycle. It's the lowest peak since late 1800s/Early 1900s
