Yes, there are also three percent of climate scientists that deny man made global warming is happening. They get a lot of attention from certain interests for that reason. Similar to the attention the scientists that denied the science that showed tobacco was bad.
So what? The CO2 and along with it temperatures are rising as expected. Yes the fact that CO2 is greenhouse gas and heats the troposphere is old science. It's old because it is indisputable. Do I need to post the charts of rising temperatures and CO2 levels again? Or the science showing CO2 is greenhouse gas? Or maybe you want to see the position statements of nearly all the major science organizations in the world again? Bottom line is that is happening and we are seeing it happen. Empirical evidence. None of the things you foolishly mention below are having any effect. Saying CO2 is a coolant is true. It cools the stratosphere. We don't live there. You know that.
The Economist has called the libertarian Heartland Institute "the world's most prominent think tank promoting skepticism about man-made climate change." Every year, Heartland hosts an "International Conference on Climate Change," bringing together a small group of contrarians (mostly non-scientists) who deny that manmade climate change is a serious problem. To promote its most recent conference, Heartland launched a short-lived billboard campaign associating acceptance of climate science with "murderers, tyrants, and madmen" including Ted Kaczynski, Charles Manson and Fidel Castro. Facing backlash from corporate donors and even some of its own staff, Heartland removed the billboard, but refused to apologize for the "experiment." Heartland does not disclose its donors, but internal documents obtained in February reveal that Heartland received $25,000 from the Charles Koch Foundation in 2011 and anticipated $200,000 in additional funding in 2012. Charles Koch is CEO and co-owner of Koch Industries, a corporation with major oil interests. Along with his brother David Koch, he has donated millions to groups that spread climate misinformation. Heartland also receives funding from some corporations with a financial interest in confusing the public on climate science. ExxonMobil contributed over $600,000 to Heartland between 1998 and 2006, but has since pledged to stop funding groups that cast doubt on climate change. Despite their industry ties and lack of scientific expertise, Heartland Institute fellows are often given a media platform to promote their marginal views on climate change. Most visible is James Taylor, a lawyer with no climate science background who heads Heartland's environmental initiative. Taylor dismisses "alarmist propaganda that global warming is a human-caused problem that needs to be addressed," and suggests that taking action to reduce emissions could cause a return to the "the Little Ice Age and the Black Death." But that hasn't stopped Forbes from publishing his weekly column, which he uses to spout climate misinformation and accuse scientists of "doctoring" temperature data to fabricate a warming trend. It also hasn't stopped Fox News from promoting his misinformation.
When the earth enters a new ice age and we are all freezing our butts off.... ... will the global warming alarmists claim they were completely successful in addressing the problem.
When you get a brain and monkeys fly will you admit you were wrong about global warming. Because this scenario is just as likely.
