This includes long term
changes in vegetation growth like moving tree lines, ice / tundra cover and deep ocean currents.
Not exact matches
However, the
changes in climatic conditions arising from climate
change could represent a far more important factor here: i.e. temperatures that increasingly exceed the optimum level for plant
growth, like those experienced this summer, shifts
in the
vegetation periods, and more frequent droughts.
To examine historical
changes in growth and mortality rates of the
vegetation there, the scientists looked at forest biomass, the cumulative result of past
growth.
Collectively, these data show general increasing trends
in both plant
growth and evaporation with recent climate
change mainly driven by
vegetation greening and rising atmosphere moisture deficits.
''
in response to rising CO2 emissions and warmer temperatures, but these new results suggest there could also be a negative impact of climate
change on
vegetation growth in North America.
On the whole, the Earth's land surface has «greened»
in response to rising CO2 emissions and warmer temperatures, but these new results suggest there could also be a negative impact of climate
change on
vegetation growth in North America.
An international team of university and NASA scientists examined the relationship between
changes in surface temperature and
vegetation growth from 45 degrees north latitude to the Arctic Ocean.
The comparison found that climate
change will spark a
growth in high - latitude
vegetation, which will pull
in more carbon from the atmosphere than thawing permafrost will release.
Positive effects of climate
change may include greener rainforests and enhanced plant
growth in the Amazon, increased
vegetation in northern latitudes and possible increases
in plankton biomass
in some parts of the ocean.
During a period of rapid population
growth, a lower heat capacity due to drying out of the soil and lost
vegetation, and an increase
in heat retaining surfaces, then homogenization more often amplifies those warming effects that is not indicative of climate
change.
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.
Without human emissions and temperature
changes, everything was
in balance: as much CO2 was entering the cold oceans (and
vegetation growth) as was emitted by the warm oceans (and rotting
vegetation).
The remaining slow drift to lower GMT and pCO2 over glacial time, punctuated by higher - frequency variability and the dust − climate feedbacks, may reflect the consequences of the
growth of continental ice sheets via albedo increases (also from
vegetation changes) and increased CO2 dissolution
in the ocean from cooling.
For Europe specifically, it is estimated that the CO2 flux from land
vegetation contributes to reduce the global net flux associated with atmospheric
growth of CO2, but the relative magnitude of this sink has been decreasing since the 1990s (from capturing 40 % of the global
growth previously, to about 20 % now), likely further to
changes in the atmospheric transport of heat and humidity over Europe.
