In praise of CO2

With less heat and less carbon dioxide, the planet could become less hospitable and less green

According to a growing number of scientists, the period of global warming that we have experienced over the past few centuries as Earth climbed out of the Little Ice Age is about to end.GettyAccording to a growing number of scientists, the period of global warming that we have experienced over the past few centuries as Earth climbed out of the Little Ice Age is about to end.

Planet Earth is on a roll! GPP is way up. NPP is way up. To the surprise of those who have been bearish on the planet, the data shows global production has been steadily climbing to record levels, ones not seen since these measurements began.

GPP is Gross Primary Production, a measure of the daily output of the global biosphere -- the amount of new plant matter on land. NPP is Net Primary Production, an annual tally of the globe's production. Biomass is booming. The planet is the greenest it's been in decades, perhaps in centuries.

Until the 1980s, ecologists had no way to systematically track growth in plant matter in every corner of the Earth -- the best they could do was analyze small plots of one-tenth of a hectare or less. The notion of continuously tracking global production to discover the true state of the globe's biota was not even considered.

Then, in the 1980s, ecologists realized that satellites could track production, and enlisted NASA to collect the data. For the first time, ecologists did not need to rely on rough estimates or anecdotal evidence of the health of the ecology: They could objectively measure the land's output and soon did -- on a daily basis and down to the last kilometre.

The rest is here.
