Yes, you're absolutely correct.
Two centuries ago, the astronomer William Herschel was reading Adam Smith's Wealth of Nations when he noticed that quoted grain prices fell when the number of sunspots rose. Gales of laughter ensued, but he was right. At solar maxima, when the sun was at its hottest and sunspots showed, temperature was warmer, grain grew faster and prices fell. Such observations show that even small solar changes affect climate detectably. But recent solar changes have been big.
Sami Solanki, a solar physicist, says that in the past half-century the sun has been warmer, for longer, than at any time in at least the past 11,400 years, contributing a base forcing equivalent to a quarter of the past century's warming. That's before adding climate feedbacks.
The UN expresses its heat-energy forcings in watts per square metre per second. It estimates that the sun caused just 0.3 watts of forcing since 1750. Begin in 1900 to match the temperature start-date, and the base solar forcing more than doubles to 0.7 watts. Multiply by 2.7, which the Royal Society suggests is the UN's current factor for climate feedbacks, and you get 1.9 watts – more than six times the UN's figure.
The entire 20th-century warming from all sources was below 2 watts. The sun could have caused just about all of it.

No. Those solar temp changes are minute and only represent the natural evolution of the sun. Global warming on the other hand has been drastic and is directly correlated to the amount of man-made CO2 in the atmosphere.
We know why global warming is happening - only the politicians are pretending to ignore it.

the sun has been getting hotter since the beginning of life.
It is one of the pieces of evidence for Gaia theory that life has provided feedback controls to maintain the climate suitable for life despite the changes of input, demonstrated by Daisyworld model.
The problem is we are now perturbing the control system by reversing the feedback (releasing CO2 that was locked away)and removing controls like forest & plankton, so it is hard for Gaia to keep the current stable position. What then happens in complex chaotic systems is that they suddenly flip to a new stable point, which will not suit most lifeforms, including humans, that have adapted to the old order.

It is possible that u are correct as the environmentalist want u to believe that CO2 is responsible,but go measure the CO2 it isn't there why? It is very simple the CO2 is not there because of our good friends the green plants that take in CO2 and put out oxygen. So the CO2 is not there and neither does it cause Global warming.

Hasn't anyone observed that archives began being recorded around the comparable time that the business revolution started? it could have been warming years earlier archives have been recorded, it does not unavoidably mean people led to it. it particularly is purely yet otherwise all those environmentalist politicians make money. "a sparkling diagnosis of international floor temperatures via NASA scientists unearths the previous year grew to become into tied for the 2nd warmest considering 1880. " ok so it grew to become into purely as warm because it grew to become into while archives have been first stored, according to risk 1870-1880 grew to become into the popular decade on checklist

The sun getting hotter shouldn't affect us, as the rays should come to earth, go through the ozone layer and back out to space. We are causing the global warming through burning fossil fuels and wrecking the earth.

We can directly correlate the solar activity to global temperature for the preindustrial period but since the industrial revolution and in particular since WW2 global temp and solar activity are not in sync any more.

I don't think the Sun is getting hotter, but I believe the Sun is putting out more radiation from more sun spots. Global warming is from 3 things: Termites releasing methane, cows releasing gases from digestion, and our industries releasing gases affecting the ozone layer.

No, sunspots & solar activity waxes & wanes with regularity..
I may have some effect on global warming but is probably not
the primary cause...The primary cause is increased C02 levels
and the generation of heat by mankind....It is a tempest in a teapot
and being cashed in on by liberals, environmentalists, Democrats,
and many scientists looking for govt. funded projects....

Perhaps partially; but the real reason is our inability to deal with the effects our consumption of energy forces on the atmosphere. Global warming is real; it's here now and we need to do something about it because our planet is on a downward spiral for self destruction.
