re: True or False: climate change

Well bmy my answer to why there is no impact on Earth's climate is best read in the last 5 paragraphs that you replied to.

But quick synopsis of the impact on Earth: man's influence on global climate is minuscule and of no significance. This is do to the fact that you are concerned with natural chemicals that naturally occur in vast amounts. Also Earth is extremely geologically active, and all of these chemicals are part of the natural geology. Finally life is teaming on and in the Earth. Most of these chemicals are considered "organic" or are involved intimately and massively in Earth life. The "circle of life" will incorporate them into additional life! Increasing the temperature, water, and essential plant food (CO2), results in a higher global life form carrying capacity!

Believe me, it's better to live now than in the Little Ice Age that you seem to believe normal or ideal! That's the best answer to your 3 hypotheticals. Warming is good and natural. Cooling is bad and natural. It has been both cooler and warmer in the past. Remember those Medieval English wines? The latest evidence indicates that the rate of warming is slowing down, but a few decades of observation on a 4.5 billion year old planet amount to nothing. If man is adding significantly to warming, good. But I don't think so. Would love to try English wine in my lifetime!
