I think you read a fascinating book alright! Let's review. Some science speculated that Venus may have had water at one time. It's plausible, they supposed, but it's not a provable fact which you're making it out to be. Also, Venus atmosphere is 100 times more dense than Earth's. Plus it's incredibly dense cloud base is made up of sulfuric acid. Once more, it's atmosphere is so dense that sunlight and heat doesn't even reach its surface. Plus Venus is about 27 million miles closer to the sun. And where did anyone come up with the ideal that Venus' surface is hotter than the sun? No. It is not.
Also - what methane and other hydrocarbons did Venus have? Methane is largely biological - there's some geological but very little. Hydrocarbons? What hydrogen? What water?
Look - the book you read may be very factual in some areas and interesting in theory or a good speculative study and I, too, feel as though we are stewards of the earth and therefore responsible for its well being as much as we can. But this is exactly this kind of "basing an entire premise off a "fact" that is only speculation" that has permeated the global warming community and degraded its credibility. There was a IPCC chief (can't remember his name) with a quote something like " there has got to be a balance and degree of importance between what language is effective and that which is fact"
You indicated that global predictions were largely accurate. Here's an article - one of about a thousand I've read, that might help contradict that.

I can't reasonably say global change is not happening. No one can. I can, however, agree that man is playing a big role in a negative way. I personally believe it's mostly due to farming techniques - something like what we experienced in the great plains in the 30's except on a global scale. Here's a video briefly explaining the desertification of the earth largely due to poor farming. I believe this deserves study because it could literally create jobs, feed the poor, and create a more stable environment globally.
I believe in God of Israel and Jesus Christ is my savior by His Grace and I believe God created our planet as all planets and created it in such a way as to balance all life giving principals by the spinning of His mind. He made our earth a virtual garden of Eden. I believe a holistic, God led approach to life and farming and human production could be encouraged, learned and taught in the same way scripture very neatly outlines in our Holy Bible.
Please remember that our wisdom is God's folly and I believe some of these green deal ideas for "fixing" our global change problems would have catastrophic effects on most and deadly effects on the poor.
