heat, pressure, and extraction removes more
dry particulate
soil than any other method.
Lack of rainfall in recent months has left
soils completely
dry and unable to release moisture that would take up
heat from the air through evaporation.
Record
heat waves baked the
soil, killed wildlife, and turned the bone -
dry terrain into kindling for firestorms that incinerated entire towns.
That
soil became even
drier in the initial
heat, which then pumped more warmth into the air above.
Harte and Shaw believe that the sagebrush and cinquefoil are more successful in the warm plot largely because
heating dries out the

The researchers will aim to find the genetic underpinnings of how plants react to stressors like drought,
heat, pathogens and pests, as well as the salt that can accumulate in
soils drying more quickly in a warming environment.
Since it is later in the afternoon, this gives the ground a chance to
heat up, and as a consequence, rather than being absorbed, the precipitation is more likely to evaporate,
drying out the
soil, the plants, etc..
Even in areas where precipitation does not decrease, these increases in surface evaporation and loss of water from plants lead to more rapid
drying of
soils if the effects of higher temperatures are not offset by other changes (such as reduced wind speed or increased humidity).5 As
soil dries out, a larger proportion of the incoming
heat from the sun goes into
heating the
soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under
drier climatic conditions.6
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
heat capacity of
dry soil is about 0.20 BTU per pound per ºF of temperature change, which is only one - fifth the
heat capacity of water.
«We've seen the effects of record
heat on snow and
soil moisture this year in California, and we know from this new research that climate change is increasing the probability of those warm and
dry conditions occurring together.»
A large container will prevent the
soil from
drying out too quickly during the
heat of summer as well.
As NOAA researcher Marty Hoerling told the media in July, drought plus
heat «is just going to make a bad situation that much worse,» since higher temperatures
dry soils out much more rapidly.
