Between the heat and
the dry vegetation conditions, conditions are ripe for wildfires, which have broken out in multiple states, and Prime Minister Julia Gillard warned yesterday that global warming will mean even more extreme weather events.
Not exact matches
After the middle Miocene, global climate change brought colder and
drier conditions to New Zealand, with significant changes to
vegetation and environments.
A shift to
drier conditions during MIS 5a is indicated by a slight increase in C4 Chloridoid grasses coupled with a 2 % shift in δ13C values, however, the
vegetation is never dominated by C4 flora.
For example, with changes in temperature and precipitation, ecosystems within Montana may shift to
drier conditions resulting in changes to
vegetation types.
Warmer,
drier climate phases can particularly increase fire risk when they follow cooler, wetter
conditions that increase fire fuel availability via increased
vegetation growth and reduced fire activity (Heyerdahl et al. 2008).
Drier desert
conditions with few clouds and little
vegetation creates a microclimate that heats up much more quickly than the other stations.
The change happens as more
vegetation grows in the warming Arctic, and forests struggle to survive against fire and insect infestations in warmer and
drier conditions.
Drought and extreme heat
dried vegetation and peat bogs, creating dangerous fire
conditions.
Drier conditions resulting from suppressed rainfall can induce more dust and smoke due to the burning of drier vegetation (Ramanathan et al., 2001), thus affecting both regional and global hydrological cycles (Wang, 2

drier vegetation (Ramanathan et al., 2001), thus affecting both regional and global hydrological cycles (Wang, 2004).
The hotter and
drier conditions were a recipe for more wildfires — with lightning strikes igniting more easily in
drier soils and
vegetation, and higher temperatures spreading the flames.
In these cases, the prevailing
dry conditions set the stage for the heat since the land is
dried out, the
vegetation is wilted, and all of the heat from the sun goes into raising temperatures, whereas ordinarily, in the process of evaporative cooling, surface water or wetness acts as an evaporative cooler (swamp cooler) of sorts.
