Sentences with phrase «causes dry soils»

Drought causes dry soils causes higher surface temperatures.

This result suggests that the reduced precipitation has caused drier soils, which in turn have enhanced the warming owing to reduced cooling by evaporation.

Not exact matches

Another cause of drying is evaporation from the top of the soil, which can be controlled with a mulch of grass clippings — but then it's hard to see how wet the soil is.

When the soil (and the wood) dry out again, the wood contracts, the rubber hose opens and lets water drip, just enough to cause the simple valve to close again.

Another theory: oxidation of organic matter — as permafrost thawed, as peaty soils burned or as a seaway dried up — may have caused the Paleocene - Eocene warming.

Nolan was influenced by the real - life ecological disaster of the Dust Bowl in 1930s North America, when the rich top soil essential to farming dried out and blew away, desolating vast areas and causing famine and mass human displacement — a situation that could yet happen again with the severe, ongoing US drought in the US.

«From a policy perspective, we have to recognize that we have been trending toward drier conditions over the last 1,500 years and the warming in Nevada is only going to exacerbate that trend,» he said, noting that «warmer temperatures cause more soil moisture to evaporate so you amplify the effects of drought when climate is warming.

Therefore, the current evidence suggests that permafrost thaw in dry soils will cause a stronger permafrost carbon — climate feedback than in water - saturated soils 1,7.

This causes land uplift that has changed the sea bottom into dry soil since the end of the ice age.

This causes the precipitating convection to move over the dry soils and reverses the polarity of the circulation.

Natural processes changed the timing and magnitude of soil moisture, streamflow, and groundwater deficits by up to several years, and caused the amplification of rainfall declines in streamflow to be greater than in normal dry years.

For example, studies of temperatures in Arizona and Mexico have shown that lost vegetation from severe overgrazing and other careless practices caused the soil surface to dry.

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.

A prominent example of massive soil drying was the «Dust Bowl» in the 1930s (Woodhouse and Overpeck 1998), which caused massive crop failures and other large - scale socio - economic impacts (Schubert et al. 2004; Cook et al. 2009).

Two processes can disrupt this system and cause a transition to a less dense transitional forest or to fire - adapted vegetation: (1) damage to canopy trees by fires fueled by dry understory vegetation; or (2) depletion of deep stores of soil moisture.

Increased rainfall variability was more significant than rainfall amount for tall - grass prairie productivity (Fay et al., 2000, 2002), with a 50 % increase in dry - spell duration causing 10 % reduction in NPP (Fay et al., 2003) and a 13 % reduction in soil respiration (Harper et al., 2005).

Further, the United Nations Convention to Combat Desertification (UNCCD) defines land degradation as a reduction or loss in arid, semi-arid, and dry sub-humid areas of the biological or economic productivity and complexity of rain - fed cropland, irrigated cropland, or range, pasture, forest and woodlands resulting from land uses or from a process or combination of processes, including those arising from human activities and habitation patterns, such as: (i) soil erosion caused by wind and / or water; (ii) deterioration of the physical, chemical, and biological or economic properties of soil; and (iii) long - term loss of natural vegetation.

The areas with enhanced warming over the USA may also be caused by drier soils from reduced precipitation, although the poor model agreement in precipitation changes for this region means this conclusion is uncertain.

Subsidence is caused by soil shrinkage and movement, and is increasingly becoming a risk to property owners due to cracks in the earth caused by prolonged dry spells which alter soil conditions.

A dry summer in 2013 would cause heavy damage to property in areas with high levels of clay in the soil.

He's discovered a number of problems that can lurk: oversaturation of soil; tree branches hanging over a home that can damage roofs and allow pests access; broken or misaligned sprinklers that can lead to dry rot or termites; inefficient rain gutters that cause drainage problems; and lawn slopes that drain toward the house rather than away, setting the scene for flooding issues.

Bitter Cucumbers A bitter taste in cucumbers may be caused by extreme dry or hot temperatures, overwatered soils or poor fertility.

Too much water can cause the plant to rot, so it is advisable to allow the soil to dry out somewhat between watering.
