Sell your sailplane before 2030
i don't care what the temperature is as long as there isn't an inversion!

It does help very much David but I got the span because I couldn't buy skill :-)

Sell your sailplane before 2030
I got the span because I couldn't buy
skill :-) Why do you think I got the turbo? To paraphrase a much-bandied aphorism, to give another option for my superior judgement to avoid situations that may require the use of my superior skill cough! Now I just have to aquire some superior skills... i don't care what the temperature is as long as there isn't an inversion! +1!! But a good inversion plus good winds sometimes means good wave. |

OMG...* Not...* global...* COOLING!* snic, snic* I think the temperature goes up and down quite a large amount (10+ C) due to a variety of natural causes, and yet stays in a bounded range without diverging to a desert world or an ice world. Somehow mammals have survived 200 million years and many cycles of this. Even great apes have survived 40 million years of it, without any technology. I guess one school is that we're just plain lucky that things haven't exceeded that range, and a small extra push could send us over, to a 2nd Mars or Venus. Frankly, I don't believe it. I think there must be some natural negative feedback "thermostat" that we don't understand yet. |

In 1804 the population of the earth was 1 billion people. It took 123
years to add another billion, then 33 years, then 14, then 12 to get the population up to 6 billion by 1999 (source https://www.learner.org/courses/envsci/unit/text.php?unit=5&secNum=4). Now the human population is roughty 10.8 billion people (source http://populationpyramid.net/world/2015/)! I don't suppose all those people blowing CO2 into the atmosphere has anything to do with this?

The CO2 that people exhale is the product of metabolism; the food that they eat is combined with Oxygen to produce water, CO2, and energy. So, it's Carbon that was in the system to start with. |

The earth is a closed system except for meteors, asteroids, etc. We are
all made of natural resources, we consume them, and we excrete them. I say more Ferraris and fewer people!
