Plants are leafing out and flowering sooner each year than predicted by results from controlled environmental warming experiments, according to data from a major new archive of historical observations assembled with the help of a NASA researcher.
Researchers use experiments that manipulate the temperature of the environment surrounding small plots of plants to gauge how specific plants will react to higher temperatures. The observed plant responses can then be incorporated into models that predict future ecosystem changes as temperatures around the globe continue to rise. But when a group of scientists compared these results to a massive new archive of historical observations, they found that the warming experiments are dramatically underestimating how plants respond to climate change.
The results were published online in the journal Nature on May 2. In addition to quantifying how a broad collection of plant species have responded to date to rising temperatures, the study suggests that the way warming experiments are conducted needs to be re-evaluated.



NASA cannot be trusted to provide honest research or data. They need to be shut down.
Up until about 10,500 years ago, it was winter all year round.
Then one year there was a day of spring (a thaw), before it returned to winter again.
Spring has been mostly advancing ever since.
Spring is definitely early here this year.
I saw some gardenias this AM. 4 weeks
early.
The azaleas at Augusta were all gone
in early April. In ~45 years of going to
the Masters, I have never seen that
before.
Of course, we could have snow next
April. But I hope God keeps early
spring going.
“The observed plant responses can then be incorporated into models that predict future ecosystem changes as temperatures around the globe continue to rise.” Not if, but as.
Jackasses. If it warms earlier, the plants
will bloom earlier. Duh.
