Trump needs to kill the 1992 UN climate and Paris treaties


If President Donald Trump merely pulls the United States out of the Paris Agreement on climate change, it will be like cutting the head off a dandelion. It will look good for a while until equally bad agreements quickly grow back when a Democrat occupies the White House again. Trump needs to dig up the […]

Trump gets it just right on Earth Day


During a week of contentious trade issues between Canada and the United States, it was gratifying to see that Prime Minister Justin Trudeau and U.S. President Donald Trump actually did agree on one thing—climate change was not even worth mentioning in their official Earth Day statements. In his official Earth Day statement, President Donald Trump […]

Inhofe is right when he said extremists will not give up


President Donald Trump is right to kill the Clean Power Plan (CPP). The rules only regulate emissions of carbon dioxide (CO2), which even school children know is not unclean. CO2 is an essential reactant in plant photosynthesis and so necessary for all life on Earth. That’s why commercial greenhouse operators routinely run their internal atmospheres […]

Pruitt is the right person for the EPA


Democratic members of the Senate Environment and Public Works Committee boycotted the February 1 vote on President Donald Trump’s pick to head the Environmental Protection Agency largely because of the nominee’s position on climate change. For example, Committee member Senator Ben Cardin (D-MD) explained that he opposed Oklahoma Attorney General Scott Pruitt’s candidacy because he […]

Trump can cancel the Paris Agreement


At first glance, it seems that President-elect Donald Trump will have to wait until 2020 to pull the United States out of the United Nations Paris Agreement on climate change. According to the treaty’s withdrawal clause, any country that wishes to quit the agreement will have to wait three years from the date on which […]

DiCaprio film is simply propaganda

To be broadcast in 45 languages in 171 countries, Before the Flood will debuted in October on the National Geographic Channel. It will also be available for free on YouTube, Twitter, […]

Obama’s ‘climate change’ forecasts have failed all over


On September 22, the U.S. Court of Appeals for the District of Columbia Circuit will hear arguments in the litigation over President Barack Obama’s Clean Power Plan (CPP). If implemented, the Environmental Protection Agency’s (EPA) regulation will require states to develop and bring into force plans to reduce carbon dioxide (CO2) emissions from existing power […]

Climate change is a natural process


In his September 8th speech announcing California’s new greenhouse gas emission laws, Governor Jerry Brown said, “If we don’t stop climate change, it’s not going to be 110 [degrees] in Imperial County; it’s going to be 130, 135! Not for a few days or a few weeks, but for months on end!” Brown’s statement is […]

So what? to environmentalist alarmism


The best answer to most of the claims by climate activists and their political allies is simply: so what? “Climate change is real,” they say. So what? Gravity and sunrise are also real. That doesn’t mean we cause them or we would be better off without them. Climate has been changing since the origin of […]

Scientists disagree on global warming


In the June 29 Leaders’ Statement on a North American Climate, Clean Energy and Environment Partnership, President Obama, Canadian Prime Minister Trudeau and Mexican President Pena Nieto agreed, “to work together to implement the historic Paris Agreement, supporting our goal to limit temperature rise this century to well below 2 degrees C.” Obama told Canada’s […]
