Does the sun’s temperture and energy output stay constant? that is the biggest question. If it stays constant then all warming and cooling are dependent on the earth and the interactions between its cycles. IF it changes in energy output, temp ect than the SUN plays a direct role in the warming and cooling of not only our planet but others also. (Hint: Since Mars and jupiter are both showing warming trends i’m going with the latter theory here)
Now some evidence to back up this view:
1 Our Sun may seem an enduring, unwavering beacon in the sky, but in truth it has a “heartbeat” of sorts–a pulsation between dimmer and brighter phases so slow that it only “beats” 9 times each century!
It’s understandable that you might not have noticed. The pulsing is not only slow, it’s also subtle. The total energy coming from the Sun only varies by about 0.1% over each 11-year cycle. For a long time scientists didn’t notice it either, which is why the Sun’s intensity is called, ironically, the “solar constant.”
The intensity of the Sun varies along with the 11-year sunspot cycle. When sunspots are numerous the solar constant is high (about 1367 W/m2); when sunspots are scarce the value is low (about 1365 W/m2). Eleven years isn’t the only “beat,” however. The solar constant can fluctuate by ~0.1% over days and weeks as sunspots grow and dissipate. The solar constant also drifts by 0.2% to 0.6% over many centuries, according to scientists who study tree rings.
These small changes can affect Earth in a big way. For example, between 1645 and 1715 (a period astronomers call the “Maunder Minimum”) the sunspot cycle stopped; the face of the Sun was nearly blank for 70 years. At the same time Europe was hit by an extraordinary cold spell: the Thames River in London froze, glaciers advanced in the Alps, and northern sea ice increased. An earlier centuries-long surge in solar activity (inferred from studies of tree rings) had the opposite effect: Vikings were able to settle the thawed-out coast of Greenland in the 980s, and even grow enough wheat there to export the surplus to Scandinavia.

Notice the source. It’s NASA. Yes that’s right. NASA says the sun energy output changes and that that change impacts climate. what part of this is so hard to understand? This is freaking NASA. Do you all understand this data? Notice that CO2 is not mentioned for the little ice age, for the warming that let the Vikings settle Greenland. It was the SUN.
Some more from the article:
Researchers still aren’t sure how small changes in the Sun’s output nudge Earth’s climate in one direction or another. To find the answer, they need to monitor our climate and keep a finger on the Sun’s “pulse” for many decades running……
….Getting consistent measurements from the ground is tricky, explains Joukoff, because Earth’s changing seasons and weather cause sunlight hitting the ground to wax and wane. On average, clouds and the atmosphere absorb or reflect 51 percent of the incoming sunlight, and this can vary widely between overcast and cloudless days.
Two big points here: one it takes DECADES to understand the Sun’s contribution to Climate change but CO2 nitwits have it figured out in 5 years. Two. the energy striking the earth varies WIDELY day to day, month to month, year to year. This blows the computer models of the CO2 nitwits full of holes. If the input of your models varies widely you can not with certainity deduce the outcome. All the models assume a constant energy stiking the earth from the Sun. the models entire conclusions is based on a faulty assumption IMO.
