 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 day call applies to almost everything the alarmists do, but we'll start with one example, the Arctic sea ice. This is a graph of the Arctic sea ice extent since 1979 and what matters is the red one, which is the September the end of the 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? Well 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 from official IPC sources in 1990 that 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 hid the 1975 low sea ice extent. Well 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 earlier in 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 and as you can see it's pretty level. For another example let's take wildfires in the USA. Look at the old regions graph it's terrible growing wildfires blamed on climate change but if you don't start at that low 1984 figure for wildfires and look at the history of wildfires in the USA this is what you get over 10 or 15 times the amount of acreage was when CO2 levels were super low.
