1940s-’80s global-mean-surface-temp normalization: Were Earth-covering sulfate aerosol clouds the cause?
Between roughly 1850 and the present day, the trend in global mean surface temperature (GMST) has, generally speaking, been positive, meaning the GMST has been rising. Interestingly, though, from 1940 to 1980 GMST stabilized. (See temperature plot at bottom). Incidentally, as reported by NASA’s Earth Observatory the GMST has increased a total of 0.7 degrees […]
Continued planet warming predicted; natural variation, human influence named likely contributing factors
The below Jul. 8, 2020 press release is from the World Meteorological Organization. The annual mean global temperature is likely to be at least 1° Celsius above pre-industrial levels (1850-1900) in each of the coming five years (2020-2024) and there is a 20% chance that it will exceed 1.5°C in at least one year, according […]
The below Jun. 15, 2020 press release is from the Sierra Club. Late last week, the Sierra Club and six other environmental groups won an important case involving the County of San Diego’s Climate Action Plan. The opinion explained in detail why the greenhouse gas mitigation measure was unenforceable. In addition to agreeing with the […]
Natural gas. It is used to dry our clothes, cook our food, heat our water and warm our homes. All true. Hot water heater But, from an air quality standpoint, how clean-burning or unhealthy are the gas-fired appliances that we use? Many, apparently, just don’t make the grade. As far as unhealthy indoor air quality […]
