As far as AGW goes, I am not convinced either way but we certainly cannot keep up with deforestation and expect the grass and shrubs to supply the oxygen we need to an ever expanding populace.
The amount of forested area in the US has been stable since the beginning of the last century, actually increased slightly.
I am constantly amazed that: 1. The sun comes up every day and heats up the surface of the earth 15-30 degrees, and cools down at night, and yet, people think that variations in energy output from the sun have no effect on our climate.
That scientists tell us that there have been 4 ice ages in North America, yet people assume this can never happen again.
That historical records show a "little ice age" from about 1500-1850, which in part coincided with greatly reduced sunspot activity. Yet people assume that nothing can change the climate of the earth more profoundly than man. If you want to see how powerful man is, notice what he does in the face of the next hurricane.
Solar cycles are 11 years in duration. Which means every 11 years there is a new solar cycle. Some solar cycles are stronger than others. It is also very obvious that we are incapable of predicting how strong or weak future solar cycles will be. So at the very best they can make predictions based upon the current solar cycle, which ends in 2018. The next solar cycle maximum will be in 2023-2024, and they have utterly no clue whether it will be quiet or active.
We have been heading into another 35-year cooling cycle since 2010, but it has absolutely nothing to do with the quiet solar cycle.
Where did you get the idea that we are heading into a 35-year cooling cycle? What are the forcings? What's the evidence for the claim?

The Taiga is the largest forest on the planet, covering one third of the North American and Eurasian continents, or 29% of the all world's forests. By itself it is capable of completely refreshing the oxygen on the planet.

From NASA's data:
Overall, from 1880 to 2010 there was a grand total increase in temperature of 0.80°C and a grand total decrease in temperature of 0.29°C. Resulting in a net temperature increase of 0.51°C.
From 1880 to 1915 the planet experienced a 35-year cooling cycle.
From 1915 to 1945 the planet experienced a 30-year warming cycle.
From 1945 to 1980 the planet experienced a 35-year cooling cycle.
From 1980 to 2010 the planet experienced a 30-year warming cycle.
Therefore, if the trend holds true, then we can expect another 35-year cooling cycle from 2010 to 2045. For the next 35 years temperatures should increase by a grand total of 0.20°C and decrease by a grand total of 0.145°C, leaving a net increase in temperature by 2045 of 0.055°C.

Sorry, the NASA data doesn't say that at all.
This idea seems to be from Don Easterbrook. A guy who has been shown to distort IPCC data and who's whacky 'predictions' have been way off in the past.
I never heard of Don Easterbrook. I told you exactly where the data originated - NASA. I cannot help it if you are too stupid to be able to distinguish fact from fiction.
