Ed Berry, physicist and climate scientist: Climate alarmists claim human CO2 emissions cause dangerous climate change. They believe a warmer planet causes bad things to happen. Therefore, they say, we must severely reduce human CO2 emissions to save the planet. Recently, they say it is a “climate emergency.” In contrast, a simple physics model (that should be taught in all schools and universities – but isn’t) shows how both natural and human CO2 flow through the atmosphere. This physics model exactly replicates the carbon-14 data. This replication proves the physics model is valid and the IPCC model is wrong. The only way we can counter the climate alarmists is with the scientific truth described by Salby, Harde, Berry, and other authors.
