Anthropogenic global warming is real, it is it is worldwide and it will affect future generations.
As an environmental engineer, I have been concerned about the environment since I got my BS (1967) and MS (1971) degrees in Civil/ Environmental Engineering and started working as a water engineer.
I have used publicly available data sources to prepare dozens of charts & graphs to looking at every aspect of global warming that I learn and understand global warming for myself . Here’s a quick summary of my evidence for global warming.
Rising Global Temperatures
- Global land and sea surface air temperature (SAT) anomalies have been rising at a rapid rate since the 1970s. My chart of NASA GISS ‘s monthly temperature anomaly trends from 1880 shows a rapid rise since the 1970s.
- Global sea surface temperature (SST) anomalies have also been rising, as shown in my chart of NOAA global SST anomalies since 1880.
- Temperature changes over the globe are not uniform . Arctic amplification cause the higher latitude areas to have a greater temperature increase than lower latitude zones. This NASA map shows that Arctic region temperatures have increased much more than lower latitudes.
Rising Mean Sea Level
- Global mean sea levels have been rising, as shown in my chart ofUniversity of Colorado – Boulder‘s satellite based monthly mean global sea level data.
Declining Arctic Sea ice Extent
- Arctic sea ice extent measures the area where sea ice exceeds 15%. Mychart of monthly Arctic sea ice extent shows a continuing decline over the satellite observation period starting in 1979. Each month shows a decline. Polar amplification magnifies the global temperature increases so that the Arctic experiences a much greater temperature increase, resulting in shrinking sea ice, reduced solar reflection and reduced albedo.
