I think most deniers have done their research.
Something I came across while researching.
A field of corn will use all the co2 within 1 meter of the ground every five minutes. That means we could easily reduce the co2 and feed the world at the same time, all we have to do is plant lots of corn.
The quiz, containing 22 questions about both science and statistics, was given to 1,540 representative Americans. Respondents who were relatively less worried about global warming got 57 percent of them right, on average, just barely outscoring those whose who saw global warming as a bigger threat. They got 56 percent of the questions correct. Read more: www.foxnews.com...
It's reasonable to assume that changes in the sun's energy output would cause the climate to change, since the sun is the fundamental source of energy that drives our climate system.
Indeed, studies show that solar variability has played a role in past climate changes. For example, a decrease in solar activity is thought to have triggered the Little Ice Age between approximately 1650 and 1850, when Greenland was largely cut off by ice from 1410 to the 1720s and glaciers advanced in the Alps.
But several lines of evidence show that current global warming cannot be explained by changes in energy from the sun:
Since 1750, the average amount of energy coming from the Sun either remained constant or increased slightly.
If the warming were caused by a more active sun, then scientists would expect to see warmer temperatures in all layers of the atmosphere. Instead, they have observed a cooling in the upper atmosphere, and a warming at the surface and in the lower parts of the atmosphere. That's because greenhouse gasses are trapping heat in the lower atmosphere.
Climate models that include solar irradiance changes can’t reproduce the observed temperature trend over the past century or more without including a rise in greenhouse gases.
how can you honestly say it's beneficial or a net 0.00000000% impact ?

Using Fox News as a science source...you're kidding, right. Why not go directly to the Heartland Institute and get your biased data from there?.
Home → Fox Distorts Nature Climate Climate Change Study's Findings In Order To Promote Climate-Change Skepticism
FoxNews.com ran a story entitled "Global warming sleptics as knowledgeable about science as climate change believers." According to the article "people who are not that worried about the effects of global warming tend to have a slightly higher level of scientific knowledge than those who are worried.” But Fox failed to note that the questions asked by the study it was citing had no relation to climate change and that the study considered more variables than Fox decided to mention.
The study, published by the Nature Climate Change journal, attempted to determine, via a series of questions, whether scientific knowledge correlated with trust or distrust of climate change. Fox said, "the study notes: 'Respondents who were relatively less worried about global warming got 57 percent of (the questions) right, on average, just barely outscoring those whose who saw global warming as a bigger threat. They got 56 percent of the questions correct'."
What was missing however, were the details. First, the survey was NOT a climate change survey, but a general knowledge survey about subjects probably learned in middle or high school, on topics ranging from thermodynamics to genetics.
Some of the questions were:
The center of the Earth is very hot (True/False)
Electrons are smaller than atoms (True/False)
All radioactivity is man-made (True/False)
It is the father's gene that determines if the baby is a boy or girl (True/False)
Not a single one of those questions touches on climate change, or on close subjects such as the water cycle or pollution.
