More CO2 – More Photosynthesis – More Greening

Someone decided to study plants that have grown for generations near high CO2 springs.

Normally these studies look at FACE experiments and then criticize those experiments because they are only single generation.

Guess what they found.?

In a new meta-analysis, Saban et al. took a different approach and assessed all of the data collected for plant response to high CO2 concentration from plants grown for multiple generations over many decades in naturally high CO2 springs. Such springs are found across the world – with 23 highlighted here- and many have been the focus of studies on the physiological responses of plants to rising CO2, similar to those undertaken in FACE experiment. Comparing these two approaches, plants subjected to higher CO2against plant lineages that have had time to acclimate, has never been done before.

High CO2 springs harbour a vast array of plant types and in contrast to FACE, provide critical insight into the decadal, long-term response of plants such as those likely to occur in future, where multiple generations ensure that time-travelling seed sources are no longer an issue. Remarkably, the analysis shows that many of the responses for spring plants are similar to those observed in FACE experiments. This gives us confidence that plants are likely to keep responding positively to rising CO2. They will not become acclimated and the increased global greening that is currently happening across the world, 80% of which is attributed to rising CO2 is likely to continue.

63% of Plants Prefer It To Be Warmer!!!!!!!

This is huge. And logical. Only idiots thought plants prefer freezing to death.

“Not all species flee rising temperatures. As the mercury has inched upward across western North America over the last 40 years, many plant species have moved downhill, toward—not away from—warmer climates, according to the results of a new study.

The finding adds to growing evidence that temperature isn’t the only factor influencing how Earth’s life will respond to climate change.”

 

Isn’t that last sentence hilarious? “Temperature isn’t the only factor …’ Well DUH! But unfortunately the AGW cult has twisted science so much that many are surprised that plants might like it warmer than colder.

 

“The results of the analysis were unexpected. More than 60% of plants shifted their distributions downward, toward warmer, lower elevations—despite significant climate warming across the regions under study, the team reported online on 24 July in Global Change Biology. Even more striking, all plants within a region—regardless of species—moved in the same direction.”

What a shocker eh? Given a choice between the cold of the 1970s, plants like it warmer. Who would have thought? …. Only people with a brain thought that!
