We’ve seen the future — and it’s weeds
What will a warming world look like? Scientists are using plants that grow around Yellowstone’s carbon dioxide-spewing thermal vents to make some predictions, says the Environmental News Network:
Plants near the vents are exposed to nearly twice as much carbon dioxide as is normal. But if carbon dioxide emissions from power plants and cars keep increasing at current rates, the amount of carbon dioxide at the vents now will become the worldwide norm in 100 years.
Among the researchers’ findings: those high CO2 levels cause native plants to lose more water and produce less protein. But weeds like Dalmatian toadflax “respond positively to elevated levels of CO2″ and grow like mad.
Hmmm. Drier plants are more susceptible to wildfire, which, as we reported, will become more common as global warming progresses. Plants growing in high CO2 levels will also provide less nutrition to wildlife and livestock. And meanwhile the bane of Western lands, invasive weeds, will find conditions more and more to their liking.
So raise a New Year’s toast to any skeptics you know who are still in denial about climate change — and get to work on converting them.
