Great news for agriculture in the 3rd world, and anyone who likes plants.
Bad news for the dying Climate Change movement, who scare us into implementing more socialism to prevent the flooding of some tiny island in the Indian Ocean in 2100.
Oh, I thought you were talking about IQs and I was going to point out that such an observation is quite obvious. Turns out you were addressing an entirely different topic. Carry on.
Incidentally, some of that greening is in the Arctic. That place is usually covered with snow and ice, except warmer temperatures have been causing it to melt away. That’s not a place we want to see green. White would be way better.
Only 0.34 per cent of Antarctica is permanently ice-free, but with rising temperatures, increased precipitation, and tourism potentially introducing new flora, it could soon be a different story. Antarctica’s climate means it’s currently pretty tricky for plants to grow there – there are only two species of plants more complicated than moss on the Antarctic Peninsula, Antarctic hairgrass and Antarctic pearlwort – but as the moss expands into new, ice-free areas, and as conditions become more conducive for plant growth, it could allow invasive species to take hold.

Leaving aside that this is a global trend not limited to Antarctica, why is that a bad thing?
OK, I'll play. What places have YOU decided aren't meant to be green? Greenland, perhaps?
The earth has been regulating/balancing CO2 in the atmosphere for millions of years-by the amount of plant growth. Growing plants absorb/consume CO2, sequestering it in their cellular structures. Increased atmospheric CO2 leads directly to more plant growth, which in turn lowers the CO2 levels in the atmosphere.
Hmmm, places not meant to be green. I didn't know such places existed. After all, only 17,000 years ago New York was under a mile-high sheet of ice! I don't think it was "meant" to be dry and fertile land but sometimes change is good.
Great news: The world is getting greener due to increased CO2
I was wondering about that. Plants love CO2, they breathe it just like we breathe oxygen. And the plants use it (and sunlight) to produce oxygen. What's not to like?
CO2 has two main effects in the atmosphere:
1.) It reflects more sunlight than nitrogen and oxygen (the main components of our atmosphere) and prevents some of the sunlight from reaching the ground. Thus, its sunlight-reflecting property makes the atmosphere a little cooler.
2.) When the rest of the sunlight gets through , it heats the ground, which heats the air above it, and makes the atmosphere warmer. And CO2 holds a little of this heat in, even though CO2 makes up less than 1% of the atmosphere and doesn't hold in much. Its heat-trapping property does make the atmosphere a little warmer.
And it's a constant tradeoff, what net effect a little extra CO2 has.
BTW, have the enviro-nuts ever produced any proof that man has anything to do with increasing CO2? Or are they still shoveling documents that contain no proof, but only refer to other documents, which refer to yet more documents... none of which contain any proof?
