GREENHOUSE EFFECT-Our life on earth depends upon the atmospheric “greenhouse” – which is a layer of gases, mainly the water vapors, in the lower atmosphere which holds heat from the sun which the earth refle
Accelerated sea-level rise in areas of decreased freshwater inflow combined with increased temperatures may lead to multiple stresses on coastal wetlands due to increased salinity and excessive inundation. In general, long-term changes in the frequency and intensity of tropical cyclones will likely ...
Human emissions of CO2 predict the increased atmospheric CO2 almost perfectly for the last 250 years. Is the earth really getting warmer?Yes, and there is complete agreement among several differnent temperature records that in the last 30 years it has warmed dramatically. (See the oldest record ...
Oceanic Ca2+ removal via CaSO4 deposition decouples the oceanic Ca2+ and HCO3− sinks, causing a decrease in CaCO3 burial and, consequently, increased ocean pH, lower atmospheric partial pressure of CO2, and global cooling. Most biogeochemical models assume that evaporite precipitation and ...
Global warming is the rise of average temperature in the earth’s atmosphere since the late 19th century. Since the beginning of the early 20th century, the earths mean surface temperature had increased by around 0.8 degrees. Warming of the climate system had become more obvious and scientists ...

The concurrence of the results of the two methods, each using 13 additional years of temperature measurements from 1998 through 2010, shows that it is humanity, not nature, that has increased the Earth's global temperature since the 19th century. Humanity is also responsible for the most recent...
From ~4.0 Ma, occurrence of extended sea ice conditions at both the Yermak Plateau and Iceland Sea document a substantial expansion of sea ice in the Arctic. The expansion occurred contemporaneous with increased northward heat and moisture transport in the North Atlantic region, which likely led...
Understanding the effects of cash crop expansion on natural forest is of fundamental importance. However, for most crops there are no remotely sensed global maps1, and global deforestation impacts are estimated using models and extrapolations. Natural ru
