CO2

There is fossil evidence of CO2 starvation at the end of the last ice age, when CO2 levels dropped to below 200 ppm. Even today’s 400 ppm is far too low for optimum plant growth.

Politifact justified its ruling that EPA is telling a half-falsehood in stating emissions are down under President Trump by stating emissions – under the booming Trump economy – are not falling quite as quickly as they did under the stagnant Obama economy. The fact is U.S. emissions continued to decline — just as EPA reported.

The United States and Western democracies as a whole are increasingly minor players among global carbon dioxide emitters, U.S. EPA data show. Without dramatic emissions reductions in China, India, and other developing nations, dramatic reductions in the United States, Western Europe, and Japan will have little impact on global carbon dioxide emissions. According to EPA […]

Global crop production sets new records virtually every year.

CNN claimed the pace of rising atmospheric carbon dioxide emissions has become alarming. A look at the objective data, however, reveals just the opposite.

Do the fundamental assumptions about CO2 in the climate models hold up?

Two years ago the big scientific news was that increasing CO2 levels were increasing plant productivity around the world. CO2 is the global food supply so this is good news indeed.

There are a lot of wacky schemes around for forcing people to stop using carbon-based energy, even though fire is still the basis for human civilization.

The great news is that world forests will be growing on net within the next few decades.

Legally correct interpretation: “The CPP exceeds EPA’s statutory authority and must be repealed.” Read CFACT’s full regulatory submission now.

A new lesson set called the Climate Change IQ (CCIQ) provides a good skeptical critique of ten top alarmist claims.

No CO2 caused global warming over the entire satellite temperature record?

The second shoe has dropped in EPA’s wondering about how to regulate CO2 emissions from power plants. As the shoe dropping metaphor suggests, EPA can now go to sleep for awhile. Everyone else is going to be very busy commenting on this complex issue. The first shoe dropped in October when EPA proposed repeal of the […]

It looks like EPA Administrator Scott Pruitt has a good procedural argument for reopening the Obama era false finding that CO2 emissions endanger human health and welfare.

It is time for the multi-billion dollar USGCRP to focus on understanding the sun-climate connection.

Archaeologists make discoveries, present their evidence, engage in discussions and debates that can continue for years, and try to defend their conclusions. Paying attention climate campaigners?

China’s coal capacity increased nearly 8 percent in 2015 — the year after they pledged to cut emissions.

“Uncertainties in the adjustments to our global temperature datasets, the small amount of warming those datasets have measured compared to what climate models expect, and uncertainties over the possible role of Mother Nature in recent warming, all combine to make climate change beliefs as much faith-based as science-based.”

Europe’s plans to reduce carbon dioxide (CO2) emissions by switching from conventional oil to biofuels actually ended up increasing emissions.

Obama administration officials are about to release regulations that could force states and cities getting federal transportation funding to cut carbon dioxide emissions.
