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. This blog and my ProcessTrends.com website combine my data analysis, total quality management and environmental interests and present R and Excel charts that show global environmental trends.
I have prepared dozens of charts & graphs looking at every aspect of global warming that I could. My early Excel based analysis is here. My more recent R based analysis is here. I have used publicly available data sources to reach my own conclusions. I provide the data links and my R script for each chart/ graph so that interested readers can confirm my work for themselves.
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.
- Satellite based global temperature anomalies show a similar trend to the NASA GISS trend. My chart of RSS satellite based global temperature anomalies since 1979 is consistent with the NASA GISS trend.
- 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, see this polar amplification discussion. My polar amplification chart 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 of University 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%. My chart 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.
Take a serious look at my climate trend charts here. Review my posts on Understanding the Role of CO2 here. Investigate, examine, review, evaluate. The problem is real, it is serious, it is worldwide and it will affect future generations.
