However, many scientists are not convinced. Georg Feulner, the deputy chair of the Earth system analysis research domain at the Potsdam Institute on Climate Change Research, has studied the effect a solar minimum might have on Earth's climate. His research has shown that temperature drops correlated to a less intense sun would be insignificant compared with anthropogenic global warming, according to the Washington Post.
Regarding the Maunder Minimum predicted by Zharkova, Feulner said, "The expected decrease in global temperature would be 0.1 degrees Celsius at most, compared to about 1.3 degrees Celsius since pre-industrial times by the year 2030," Feulner told the Post. Furthermore, this isn't the first time research has predicted waning heat from the sun, to which experts also said that man-made global warming won't be trumped.
The reason behind Zharkova’s claim of lowered temperatures, beginning around 2030, was that her team’s new solar cycle model predicted that there would be a 60 percent drop in magnetic energy from the Sun. Looking at the magnetic wave patterns predicted by their model, the team predicted that there would be fewer sunspots over the next two solar cycles: Cycle 25, which peaks in 2022, and Cycle 26, which runs from 2030 to 2040. This indicates less solar magnetic energy during that time.
"In Cycle 26, the two waves exactly mirror each other - peaking at the same time but in opposite hemispheres of the Sun," Zharkova said at the conference. "Their interaction will be disruptive, or they will nearly cancel each other. We predict that this will lead to the properties of a 'Maunder Minimum’."
The problem with this prediction, says Plait, and in comparing what’s about to happen with the 17th century Maunder Minimum, is that a drop in the magnetic activity of the Sun will only have a marginal effect on its light/heat output. He explains at Slate:
"There has been research asking what would happen if it is weak next time and concludes it will have moderate localised effects - not global cooling. In fact, the very first line of the abstract of that paper is this: 'Any reduction in global mean near-surface temperature due to a future decline in solar activity is likely to be a small fraction of projected anthropogenic warming.'"

I found a couple of articles that suggest that the world's largest fossil fuel companies have knowingly worked to deceive the public about the reality and risks of human induced climate change.

This is interesting because on public discussion boards across the world wide web, there are often heated debates between those of us who are concerned about human impact on this planet's climate and environment versus those who do not accept this and have a plethora of excuses, fallacies, and concerns of hidden agendas they cling to as fallback positions(i.e. AGW is a hoax to raise our taxes!!!).
I think anyone who is well traveled and able to think freely can see we are causing great changes to this planet, and perhaps it is time to make changes, possibly drastic changes in an attempt to keep this planet hosptitable for our offspring.
