Global Warming
Climate change includes global warming, which is the gradual increase in the earth's temperature. It is brought on by an increase in greenhouse gas concentrations in the atmosphere, primarily as a result of human activities like farming and the burning of fossil fuels. For 2.5 million years the Earth's climate has fluctuated cycling from ice ages to warmer times, but recently the planet's temperature has risen unusually fast about 1.2 to 1.4 degrees Fahrenheit scientists believe it's human activity that's driving the temperatures up a process known as global warming. Ever since the industrial revolution began factories power plants and eventually, cars have burned fossil fuels such as oil and pull releasing huge amounts of carbon dioxide and other gases into the atmosphere, these greenhouse gases trap heat near the earth through a naturally occurring process called the greenhouse effect.
The greenhouse effect begins with the Sun as well as the energy it emits toward the earth, the earth, and the atmosphere absorbs a portion of this energy while the remainder is radiated back into space naturally-occurring gases in the atmosphere trap some of this energy, and reflected back warming the earth scientists now believe that the greenhouse effect is being intensified by the extra greenhouse gases that humans have released evidence of global warming include a recent string of very warm years scientists report that 1998 was the warmest year in measured history with 2005 coming in second meanwhile readings taken from ice cores show that the greenhouse gases carbon dioxide and methane have hit their highest levels in the past 420 thousand years.
Arctic sea ice is also shrinking according to NASA studies the extent of Arctic sea ice has declined about 15 percent in the last 50 years as long as industrialized nations consume energy and developing countries increase their fossil fuel consumption. The number of greenhouse gases in the air will keep increasing. researchers predict that temperatures will increase about two to 10 degrees
Fahrenheit by the end of the century what's less certain is what rising temperatures mean for the planet some climate models predict subtle changes others forecast rising sea levels which could flood coastal areas around the world weather patterns could change making hurricanes more frequent severe droughts could become more common in warm areas and species unable to adapt to the changing conditions would face extinction although much remains to be learned about global warming many organizations advocate cutting greenhouse gas emissions to reduce the impact of global warming consumers can help by saving energy around the house switching to compact fluorescent light bulbs and driving Weekly mileage in the car has decreased. Simple improvements could keep the earth healthy and cooler in the future like driving less, recycling more, avoiding products with lots of packaging, planting a tree, turning off electronic devices, and these types of many things.
