New data analysis tools and models reshape the "Climate Change" models.
The good news appears to be more plant growth and a new balancing model for CO2.
New science and data models keep reshaping our view of the planet.

Article Overview:
Analyzing the ice, Dr. Campbell and his colleagues have discovered that in the past century, plants have been growing at a rate far faster than at any other time in the past 54,000 years. Writing in the journal Nature, they report that plants are converting 31 percent more carbon dioxide into organic matter than they were before the Industrial Revolution.
For decades, scientists have been trying to figure out what all the carbon dioxide we’ve been putting into the atmosphere has been doing to plants. It turns out that the best place to find an answer is where no plants can survive: the icy wastes of Antarctica.
As ice forms in Antarctica, it traps air bubbles. For thousands of years, they have preserved samples of the atmosphere. The levels of one chemical in that mix reveal the global growth of plants at any point in that history.
“It’s the whole Earth — it’s every plant,” said J. Elliott Campbell of the University of California, Merced.
In the mid-2000s, atmospheric scientists discovered a powerful new way to measure plant growth: by studying an unimaginably rare molecule called carbonyl sulfide. Note: this is really interesting to understand plant growth
“The pace of change in photosynthesis is unprecedented in the 54,000-year record,” Dr. Campbell said. While photosynthesis increased at the end of the ice age, he said, the current rate is 136 times as fast.
With all that extra carbon dioxide going into plants, there has been less in the air to contribute to global warming. The planet has warmed 1.4 degrees Fahrenheit since 1880, but it might be even hotter if not for the greening of the Earth.
Dr. Berkelhammer, who was not involved in the new study, said the research would serve as a benchmark for climate projections. “It means we can build more accurate models,” he said.
