Global Warming Again
See I said don't get me started but noooooo, someone did it anyway, so here ya go, my rant.
In the first place WE are NOT totally responsible for the global condition today, granted we have not helped the situation but this phenomenon is nothing new globally speaking.
There has been an abundance of Solar activity such as flares and sunspots, mass coronal ejections etc. turning up the heat here on Earth. Protection from these blasts of heat is provided by our atmosphere and normally this would cause cyclical climate changes within normal limits. For complete solar information go HERE. There are links at the bottom of the page to other sites as well.
The magnetic field is also involved, periodic shifts in polarity are reducing the capability of the Earths' magnetic field to repel Solar radiation. NASA has an excellent site which describes this HERE.
Add in the daily Airline flights of 3000 per day in the US injecting pollutants in the form of soot and vapor actually make their own cloud formations, read HERE.
Oh yea, I forgot the Rainforest's, a vital part of the planets' ecosystem is being consumed by humans also, read about it HERE.
"Originally tropical rainforest's covered 15-18 million km2 of land surface, but by 1989 this area had been reduced by human activity to less than eight million km2. The total area remaining as tropical rainforest is even smaller now, as rainforest's are being removed at a rate of 100,000 to 200,000 km2 per year, with approximately the same area being greatly disturbed (Skole and Tucker, 1993; Katzman and Cale, 1990); some say, several times as much (Pimm, et al., 2001). Sponsel, Bailey and Headland (1996) estimate the deforestation rate as 142,000 km2 annually. Potter (1999) estimated that 13.7 million hectares are deforested annually in developing countries, equivalent to 137,000 square km, but down from 15.5 million hectares (155,000 km2) per year in the 1980's. Achard, et al., (2002) give figures of 5.8 million hectares (58,000 km2) annually, as well as 2.3 million hectares (23,000 km2) degraded in the humid tropics. Meadows, Meadows and Randers (1992) estimate that 17 million hectares (170,000 km2) per year of rainforest (2.1% of total area) were cut in 1990. The discrepancies and uncertainties are due to the fact that the main means of measuring deforestation - satellite imaging - is only approximate, and may underestimate the actual area cut."
Now we have a brief summary of events causing global warming, some of which have absolutely nothing to do with human activity, but combined with human activity, threaten our very existence here on Earth.
Can it be fixed? yes, before it is too late? no. We are not as permanent an occupant of the Earth as we believe ourselves to be. We are but temporary caretakers of it, fail to properly take care of it and we will be eliminated.
We have not been the first occupants and won't be the last.
