«If the
vegetation is
more clumped... they'll end up on the same food plant, which means they'll contact each other and

«You are probably getting a
vegetation change due to that first fire that's going to
cause more high - severity fires in the future and potentially the emergence of non-forest that could last for a long time.»
Also that task is made easier by the excess CO2 in the air today, which
causes vegetation to take up CO2
more efficiently.
Worldwide,
vegetation fires are showing a trend toward longer burning periods, increased fire severity, larger areas burned and increased (mostly human
caused) frequency — with all of these factors contributing to
more damaging environmental impacts, higher shares of emissions and increasing socioeconomic costs, including greater threats to human health and security.
wars, burning and exploding atom bombs seem to be an (extra)
cause for cooling,
more vegetation an (extra)
cause for warming.
A few scientists have recently suggested that the «CO2 - fertilisation effect» may be
causing land
vegetation to absorb much
more of the excess CO2 than was previously thought.
These facts help explain why, in spite of the Earth's air temperature increasing to a level that the IPCC claims is unprecedented in the the past millennium or
more, a recent study by Randall et al. (2013) found that the 14 % extra carbon dioxide fertilization
caused by human emissions between 1982 and 2010
caused an average worldwide increase in
vegetation foliage by 11 % after adjusting the data for precipitation effects.
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).
With respect to why there was a significant increase in tree density over the past several decades, Dolanc offers that the changes in the density and composition of lower - elevation forests are consistent with fire suppression; but that the density increases in high - elevation
vegetation types (subalpine forests generally don't burn) are «
more likely to be
caused by changing climate.»
Combined with diminished precipitation, high temperatures in California are
causing soils and
vegetation to lose moisture earlier in the spring and stay dry later in the fall, meaning the landscape is flammable for
more of the year.
Thirty years to establish a climate state seems a long time, as within that period there may be notable shifts to a number of different prevailing patterns of cold / warmth / wet or drought that, on a human scale affects agriculture and horticulture by impacting on what crops may be grown successfully, may affect the tourism season, may
cause a consumer to use
more or less energy in their home, and also impact on nature by affecting the populations of wild life and
vegetation.
What is known is the ever increasing global CO2 level will
cause further increases in crop yields and
more increase in growth of natural
vegetation.
Or will warming reduce the forests — and perhaps also tundra
vegetation — by
causing more wildfires and insect outbreaks?
