The VENT

 From the June 7th article in the National Post, ‘In Praise of CO2′ by Lawrence Solomon.

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.

…

This blossoming Earth could now be in jeopardy, for reasons both natural and man-made. 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. The oceans, which have been releasing their vast store of carbon dioxide as the planet has warmed — CO2 is released from oceans as they warm and dissolves in them when they cool — will start to take the carbon dioxide back. With less heat and less carbon dioxide, the planet could become less hospitable and less green, especially in areas such as Canada’s Boreal forests, which have been major beneficiaries of the increase in GPP and NPP.
