Over the past two decades, researchers have
seen changes in the vegetation around the tundra.

For their study, published Nov. 8, 2016,
in Environmental Research Letters, the researchers first analyzed
vegetation cover data for the months leading up to the storm to
see if the Syrian conflict had really
changed the land cover that much.
«There are real questions about whether we are beginning to
see a shift
in vegetation types driven by fire activity fueled by fire suppression and climate
change.»
The silicate + CO2 - > different silicate + carbonate chemical weathering rate tends to increase with temperature globally, and so is a negative feedback (but is too slow to damp out short term
changes)-- but chemical weathering is also affected by
vegetation, land area, and terrain (and minerology, though I'm not sure how much that varies among entire mountain ranges or climate zones)-- ie mountanous regions which are
in the vicinity of a warm rainy climate are ideal for enhancing chemical weathering (
see Appalachians
in the Paleozoic, more recently the Himalayas).
The varying
vegetation creates
changing habitats, and so we will
see different animals
in each section of the park.
In the mountains,
vegetation changes and you'll
see cabbages, maize and potatoes.
As we ascend the mountain, we will notice a
change in temperature and
vegetation; we will
see coffee plantations as
[Response:
Changes in vegetation as a response to warming as
seen by satellites over the same areas are obviously caused by former - USSR apparatchiks painting the ground green.]
E.g., human - caused albedo variations from desertification, and to some extent tropical deforestation, were connected with past global climate
changes by Sagan et al. (1979); a pioneering model confirming «the long - held idea that the surface
vegetation... is an important factor
in the Earth's climate» was Shukla and Mintz (1982); Amazon Basin: Salati and Vose (1984); more recently,
see Kutzbach et al. (1996).
FOR IMMEDIATE RELEASE An extensive new study by climate impact researchers warns that humans will struggle to cope with drastic and rapid
changes to the planet unless greenhouse gas emissions rates are cut now London, 8 October − Allowing the Earth's temperature to rise by more than 2ºC will
see dramatic
changes in vegetation across the planet and expose a billion more people to severe water scarcity, according to new research.
The 1942 «peak» is nowhere
seen in any other direct measurement (high resolution ice cores from Law Dome) neither
in stomata data for the past century, neither
in coralline sponges, the latter based on 13C / 12C ratio's which certainly should
change if there was an important
change in inputs or outputs from
vegetation or oceans.
Engineers and scientists from US universities analysed
vegetation cover
in the region prior to the storm to
see if the Syrian civil war had
changed the land surface drastically enough to mask the view from space.
So I think, around the carbon budgets, a question that I would like to
see more clarity on is whether land - based
vegetation will continue to absorb carbon dioxide at the rate it currently is, or whether
in a future climate, that drawdown of carbon by plants on land will
change.
The natural variation that has led us out of the Little Ice Age has a bit of frosting on the cake by land use; and, part of that land use has resulted
in a
change in vegetation and soil CO2 loss so that we
see a rise
in CO2 and the CO2 continues to rise without a temperature accompaniment (piano player went to take a leak), as the land use has all but gobbled up most of the arable land North of 30N and we are starting to
see low till farming and some soil conservation just beginning when the soil will again take up the CO2, and the GMO's will increase yields, then CO2 will start coming down on its own and we can go to bed listening to Ave Maria to address another global crisis to get the populous all scared begging governments to tell us much ado about... nothing.
Thus what you
see as wiggles
in the increase per year is the direct result of temperature
changes in ocean surface and
vegetation (for the latter, precipitation also plays a role).
The latest article on greening I've
seen is from a couple of months ago: «Human population growth offsets climate - driven increase
in woody
vegetation in sub-Saharan Africa» https://www.nature.com/articles/s41559-017-0081 Thanks to climate
change and CO2 increase the balance is positive towards greening over human deforestation.
The
changes are
seen in TOA power flux as aresult of
changes in cloud, dust, snow and ice,
vegetation etc..
