Global Dimming? The Search For Truth Goes On.....

Things are not always as simple as we might like them to be. Here is some independent thought on the issue of climate change. Someone give Al Gore a wake-up call, please.

Try googling "Global Dimming".
This may explain why we are getting colder temps when we are supposed to be getting warmer. Inadvertently some pollution (mainly particulates) is counteracting the effects of carbon dioxide. It's kind of like taking a medication to counteract the side effects of another medication that counteracts the side effects of a medication. Ironically, efforts to reduce particulate pollution may be letting global warming get worse.

Basically the pollution problem is far more complex that anybody thought. So some areas may get warmer while other places get cooler. So light a burn pile up to stop global warming. Make certain it's good and wet. Then again we could be creating a strange atmospheric brew that could do some really weird things in the future. We just don't know.

Global dimming
From Wikipedia, the free encyclopedia
Global dimming
is the gradual reduction in the amount of global direct irradiance at the Earth's surface that
was observed for several decades after the start of systematic measurements in
1950s. It is thought to have been caused by an increase in particulates such as sulfur
aerosols in the atmosphere due to human action. The effect varies by location,
but worldwide it has been estimated to be of the order of a 4% reduction over
the three decades from 1960–1990. The trend reversed during the past decade.
Global dimming has interfered with the hydrological cycle by
reducing evaporation and may have caused droughts in some areas. Global dimming
also creates a cooling effect that may have partially masked the effect of greenhouse gases on global
warming
