U.S. analyst Dr Ed Berry writes: "We have already won the science debate, but few people understand this. The alarmists have no scientific case. Now we must win the political debate....Our task is great. We must show the public why human CO2 does not change the climate. Our goal is to get climate change out of politics and back into science. The idea that we have a 'climate emergency' is a product of a crippled mind."
