What is the Carbon Uptake Period ?

Question

How has the c.u.p. been effected by climate change?

Answer 1

I second what Speakeasy wrote. The only things that effect this is if the Spring and Summer seasons are either dryer or colder then average. (A colder spring shortens the growing season.) (And a dryer spring and summer effect plant growth and can kill young trees.)

Answer 2

During the Spring and Summer months in the Northern Hemisphere, increased plant growth causes greater CO2 absorption to build plant tissues.  That period ends in Autumn, when rotting vegetation releases some of its carbon back into the atmosphere.

As the climate has warmed, billions of acres of new land has been exposed by retreating ice allowing for forest growth, increasing the quantity of carbon uptake during this period.

The glaciers have retreated about 2,000 miles since the end of the last Ice Age.  That is a lot of new forest land.

Warming has also extended the growing season in a lot of temperate zones, allowing for longer carbon uptake periods and more robust plant growth.
