Sounds more like a cascading effect of prior warming.
quote:
In eastern and southeastern tropical South America, including the Amazon rainforest, severe drought spurred by El Nino made 2015 the driest year in the past 30 years. Temperatures also were higher than normal. These drier and hotter conditions stressed vegetation and reduced photosynthesis, meaning trees and plants absorbed less carbon from the atmosphere. The effect was to increase the net amount of carbon released into the atmosphere.
In contrast, rainfall in tropical Africa was at normal levels, based on precipitation analysis that combined satellite measurements and rain gauge data, but ecosystems endured hotter-than-normal temperatures. Dead trees and plants decomposed more, resulting in more carbon being released into the atmosphere. Meanwhile, tropical Asia had the second-driest year in the past 30 years. Its increased carbon release, primarily from Indonesia, was mainly due to increased peat and forest fires -- also measured by satellite instruments.

Most of the world's land mass warm enough for vegetation is in the northern hemisphere.
Are we sure those fluctuations of CO2 concentrations are not lagging indicators of ocean CO2 release and absorption since most of the land mass in in the northern hemisphere?
CO2 concentration increase during our winter months and the southern hemisphere's summer months where most of the oceans exist. As the southern oceans seasonally warm they are forced to release dissolved gases CO2 being one of them. And thus atmospheric CO2 concentrations increase. Vise versa for our warm season and the southern ocean's cold seasons.

If only we had an example of previous warming periods to test this hypothesis.

bullshite. Its just like polls here in Trumpsucker HQ. We hate polls unless they're MAGA, we hate science unless its MAGA, we hate sitting through the national anthem unless its MAGA.
We hate the facts unless they're MAGA.

Watch video as the Earth breathes here.
(Video shows carbon dioxide concentrations from for the whole year of 2006, pretty dramatic stuff by the time summer rolls around.)

What is the monthly, weekly, daily concentration of dissolved ocean CO2 as a function of temperature? Have we measured that?

Only on the Poli Board can we find people celebrating a rapid acceleration of CO2 in the atmosphere even beyond what humans are producing because some of it is coming from a lack of vegetation that is dying from climate change.
Nevermind that it blows a hole into one of this board's common theories that more CO2 is good for plants.

right? Posted on 10/13/17 at 11:13 am to Bard
This is not saying what you think it is saying.

Don't frick with their religion.
You can see how sensitive they get.

I am sure photosynthesis is the dominant driver of the annual CO2 cycle.

I wish you were smart enough to be able to see how ironic it is that you called someone else sensitive.

Dude, there is a big difference of hating polls and distrusting polls. If you don't think the polls have been skewed against Trump for the last year or so then you're just not honest enough to continue conversing with.

What exactly are you trying to argue?
Are you saying that deciduous trees in the Northern Hemisphere do not affect atmospheric carbon dioxide concentrations during a year?

This can't possibly be science!
