Rise In CO2 Has 'Greened Planet Earth' (bbc.com)
schwit1 quotes a report from BBC: Carbon dioxide emissions from industrial society have driven a huge growth in trees and other plants. A new study says that if the extra green leaves prompted by rising CO2 levels were laid in a carpet, it would cover twice the continental USA. Climate skeptics argue the findings show that the extra CO2 is actually benefiting the planet. But the researchers say the fertilization effect diminishes over time. They warn the positives of CO2 are likely to be outweighed by the negatives. The lead author, Professor Ranga Myneni from Boston University, told BBC News the extra tree growth would not compensate for global warming, rising sea levels, melting glaciers, ocean acidification, the loss of Arctic sea ice, and the prediction of more severe tropical storms. The new study is published in the journal Nature Climate Change by a team of 32 authors from 24 institutions in eight countries. A new study has also shown that ever since Americans first heard the term global warming in the 1970's, the weather has actually improved for most people living in the U.S. The study published in the journal Nature found that 80% of the U.S. population lives in counties experiencing more pleasant weather than they did four decades ago.
It sounds good that crops will be more productive. So will other things, though. There was an experiment in which poison ivy was grown in higher CO2 conditions. It grew better and produced more urushiol (the stuff that causes you to have an allergic reaction). Crops may grow better, but so will weeds. It wouldn't surprise me if that included some invasive weeds like kudzu. If it stays warmer, pests might not die off in the cold; the mountain pine beetle is an example. Furthermore, there's not only increased temperatures and longer growing seasons; rainfall patterns will shift, too. Areas that currently grow crops might become arid and either have to grow different crops or not be productive at all. Other areas, such as the northern US, are likely to become wetter. Maybe you have longer growing seasons in some areas, but I'm not sure how much of a real gain there will be if the rainfall moves poleward with the warm temperatures.
That's because the question has been answered time and time again. If you are too lazy to look for the answers, you are beyond help.
I guess the thing you have to consider is that any reliable cycle has now been thrown out the window.

Yes and we all know that no one can ever return to visit a place once they've moved away, nor can they ever look at weather reports of places they've left either.
I've never been to Dubai, but there's this magical thing I can do, I can go to www.bbc.co.uk/weather type in Dubai, and find out that it's 40c on Thursday, which to me and many others would be unbearably hot.
How is this wizardry possible you ask? Well adolf, it's all really just down to this thing called communication.
