The results of recent elections in Australia, US, and UK, despite all the opinion poll predictions, have shown that the silent majority of people are not buying the AGW theory. The latest surveys show, with the Covid-19 contagion spreading around the world, global warming has been relegated to the lower end of their list of concerns. Intergovernmental Panel on Climate Change (IPCC) who do no original research of their own, but instead periodically assess and published scientific literature on climate change, have done their best to exaggerate the rate of warming by the use of misleading climate charts.
Global Warming is a serious yet controversial enough topic without bringing in bad data. While both charts above and below show the last decade, 2001-2010 as the hottest, the above and the second one below use a broken Y-axis that begins at 13.4°C instead of starting at zero. The temperature graph does not hide this fact, and you can see that the chart’s Y-axis starts at 13.4°C, but the most visually prominent piece in the graph is, well, the graphs! And it screams the message that global temperatures are going off the charts – it’s time to panic. from Abhinan’s Tech and Analytics.
We don’t know the proportion of Anthropogenic Global Warming (AGW) after 2010. The IPCC had calculated that up to 49.9% of the warming between 1950 and 2010 were mainly due to natural variability but have not revealed the ratio in the years after 2010. Were the higher temperatures during the El Nino event of 2016 and in the years immediately before and after due to natural variability? Maybe less may be more than 50%…the truth is we simply don’t know. Which is probably the case according to an article in the New York Times, January 1996: The average temperature for 1995 was 58.72 degrees Fahrenheit, (14.88 Celsius) according to the British data, seven-hundredths of a degree higher than the previous record, established in 1990. The British figures, based on land and sea measurements around the world, are one of two sets of long-term data by which surface temperature trends are being tracked. The other, maintained by the NASA Goddard Institute for Space Studies in New York, shows the average 1995 temperature at 59.7 degrees, (15.38 Celsius) slightly ahead of 1990 as the warmest year since record-keeping began in 1866. But the difference is within the margin of sampling error, and the two years essentially finished neck and neck. The preliminary Goddard figures differ from the British ones because they are based on a somewhat different combination of observations around the world. According NOAA climate data the global temperature for 2019 was 14.85 degrees Celsius!!
The above graph shows the same warming from year to year as published in 2010.
