Global warming essay
Global warming essay Global warming essay and Scientists have been taking widespread measurements of Earth’s surface temperature since around 1880. These data have steadily improved and, today, temperatures are recorded by thermometers at many thousands of locations, both on the land and over the oceans. Different research groups, including the NASA Goddard Institute for Space Studies, Britain’s Hadley Centre for Climate Change, the Japan Meteorological Agency, and NOAA’s National Climate Data Center have used these raw measurements to produce records of long-term global surface temperature change. These groups work carefully to make sure the data aren’t skewed by such things as changes in the instruments taking the measurements or by other factors that affect local temperature, such as additional heat that has come from the gradual growth of cities.These analyses all show that Earth’s average surface temperature has increased by more than 1.4°F (0.8°C) over the past 100 years, with much of this increase taking place over the past 35 years. A temperature change of 1.4°F may not seem like much if you’re thinking about a daily or seasonal fluctuation, but it is a significant change when you think about a permanent increase averaged across the entire planet. Consider, for example, that 1.4°F is greater than the average annual temperature difference between Washington, D.C., and Charleston, South Carolina, which is more than 450 miles farther south. Consider, too, that a decrease of only 9°F (5°C) in global average temperatures is the estimated difference between today’s climate and an ice age. In addition to surface temperature, other parts of the climate system are also being monitored carefully Global warming essay.
For example, a variety of instruments are used to measure temperature, salinity, and currents beneath the ocean surface. Global warming essay weather balloons are used to probe the temperature, humidity, and winds in the
