  • sunlight
  • This phenomenon results in the heating up of greenhouse, much like the inside of a car parked in sunlight, and keeps the plants warm enough to live in the winter. (hubpages.com)
  • emissions
  • Put another way, 99.88% of the greenhouse effect has nothing to do with carbon dioxide emissions from human activity 8 . (realclimate.org)
  • The side-effects could be devastating and technologies with low environmental impact and no "greenhouse gas" emissions are likely to be of increasing importance over the coming decades. (pveducation.org)
  • Resumo em inglês Soil is an important pool for C stocks and plays a fundamental role in greenhouse gas emissions and consequently in climatic changes. (worldwidescience.org)
  • Specific topics include inventory of carbon emissions and sequestration of US cropland soils, carbon dynamics and sequestration of a mixed-grass prairie as influenced by grazing, possibilities of change in the greenhouse gas balance of agro ecosystems in Canada, and reconstruction of soil inorganic and organic carbon sequestration across broad geoclimatic regions.

  • temperatures
  • While not all scientists agree that this year's higher temperatures can be attributed to the greenhouse effect, most argue that a significant global warming is inevitable, even if massive measures are immediately taken to halt air pollution. (deseretnews.com)
  • On the flip side, however, changes in atmospheric conditions had an opposite effect in Europe - lowering autumn temperatures by as much as 1 degree C (1.8F). (berkeley.edu)
  • weak
  • There is no simple way to demonstrate the greenhouse effect of a small sample of air experimentally with a jar or any other enclosure because over the scale of inches to feet (or even tens of feet) the effect is so weak it cannot be measured with standard thermometers. (drroyspencer.com)
  • NOTE: Even though handheld IR thermometers are supposedly tuned to work at IR wavelengths where atmospheric greenhouse effects are weak, there is still a residual effect. (drroyspencer.com)
  • describe
  • What amazes me are the number of science education web pages out there which claim to describe experiments that supposedly demonstrate the greenhouse effect using jars or other enclosures. (drroyspencer.com)
  • NASA
  • On the June day that a NASA scientist told Congress that the "greenhouse effect" may be linked to the devastating drought and withering heat of 1988, the mercury hit 98 degrees in the nation's capital, crept up to 90 degrees in Cincinnati, soared to 97 in Dallas and topped 100 in Nashville.

  • This video from NASA gives a good, student-friendly introduction to greenhouse gases. (calacademy.org)
  • scientist
  • But James E. Hansen, the National Aeronautics and Space Administration scientist who testified before Congress, proclaimed that the greenhouse effect has arrived and cited as evidence the fact that the first five months in 1988 were the hottest on record. (deseretnews.com)
  • however
  • However, considering the greenhouse effect on both the grapevine phenology and the pruning time, grapevines early pruned showed an anticipation of harvest of 32 days when compared to the normal pruning time in the Serra Gaúcha region. (worldwidescience.org)
