[ RadSafe ] Climate change

[Howard Long]

Kjell,
Ask presently snowed-in Americans whether they would LIKE the  slight average temperature increase due in the next century (about 1/100 of the daily variation, giving 6" rise in ocean level
according to ICCA).

Seven times as many deaths (700% mortality) are from cold-induced disease as from 
heat-induced disease in all 9 countries studied by Howard Maccabee.

Pray for global warming and CO2 levels of 600 ppm plus.

Howard Long

[We were discussing this back in the '70s in my meteorology and oceanography classes at the University of Michigan and those profs were smart guys.]  Any change in the solar output or axis wobble will make some small changes.  Continuing to pump greenhouse gases (methane, CFCs, and carbon dioxide) into the atmosphere increases the heat containing capacity of the atmosphere. (Ok, to be technically correct, you are increasing the capacity of the atmosphere to capture outgoing radiation and radiating back to the earth as heat.  But, in the overall picture, it results in an increase in the earth's temperature.) By analogy with solar output and axis wobble, compare the water content of an 8-oz glass to that of a 16-oz glass.  No matter how the rate at

When the greenhouse gases CO2 and methane concentrations are high, so are all of the geochemical markers for increased temperature, ie, the O18/O16 ratios, etc.  To deny any link between greenhouse gases and the average earth temperature is an extreme case of reverse hubris.
