The way climate alarmists intentionally deceive you is by changing the starting date of their graphs, so as to suit their agenda. I'll explain. The starting date call applies to almost everything the alarmists do, but will start with one example of Arctic sea ice. This is a grant of the Arctic sea ice extent since 1979, and what matters is the red one, that's just the September the end of summer graph, and it shows a continual decline in the extent of the sea ice. This is the alarmist graph. So why did they choose 1979 as the starting date? Why would you can guess? That's because there's a very high level of sea ice then. So let's now take that graph and attach it to another graph that shows the history prior to 1970. This graph shows, and it's been the official IPC source, it's a 1999, where the actual sea ice extent was far lower, just a few years before 1979, in 1975, and it is claimed these are measured by the same system by satellite. So they did the 1975 low sea ice extent. But let's extend further back in time, not using satellite, but traditional, well-tested methods to observe Arctic sea ice extent. Now, a full deception is revealed. The ice extent was much lower early in the 1950s, when the actual CO2 levels were considered very safe. There is simply no relationship shown here, between the extent of Arctic sea ice and the CO2 level. The red line in this graph shows the mean Arctic sea ice extent for the last 15 years. Now you can see it's pretty level. For another example, let's take wildfires in the USA. Look at the origin graph, it's terrible, growing wildfires, and ain't don't climate change. But if you don't start at that low 1984 figure, the wildfires, and look at the history of wildfires in the USA, this is what we get. There were 10 or 15 times the amount of acreage loss, when CO2 levels were super low.
