Transcript of GLOBAL WARMING

IS GLOBAL WARMING A MYTH OR REAL? Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. This is a type of greenhouse effect. The planet has been through a lot worse than us. Been through earthquakes, volcanoes, plate tectonics, continental drift, solar flares, sun spots, magnetic storms, the magnetic reversal of the poles … hundreds of thousands of years of bombardment by comets and asteroids and meteors, worldwide floods, tidal waves, worldwide fires, erosion, cosmic rays, recurring ice ages … And we think some plastic bags and some aluminum cans are going to make a difference? The planet isn’t going anywhere. WE are! Climate changes in the past suggest that our climate reacts to energy input and output, such that if the planet accumulates more heat than it gives off global temperatures will rise. It's the driver of this heat imbalance that differs. Currently, CO2 is imposing an energy imbalance due to the enhanced greenhouse effect. Past climate change actually provides evidence for our climate's sensitivity to CO2. REAL MYTH Even before SUVs and other greenhouse-gas spewing technologies, Earth's climate was changing, so humans can't be responsible for today's global warming. The planet can't be warming when my front yard is covered in several feet of snow. … This winter has been one of the chilliest Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies. Many Americans take for granted the idea that an increase in carbon dioxide in Earth’s atmosphere is what leads to an increase in Earth’s temperature. In fact, that is only a theory. Please save me! my temperature is rising, and very soon I might EXPLODE! Professor Zbigniew Jaworowski, Chairman of the Scientific Council of the Central Laboratory for Radiological Protection in Warsaw, Poland published his research that found that a change in Earth’s temperature would have more to do with cloud cover and water vapor than carbon dioxide concentration in the atmosphere. Local temperatures taken as individual data points have nothing to do with the long-term trend of global warming. These local ups and downs in weather and temperature can hide a slower-moving uptick in long-term climate. To get a real bead on global warming, scientists rely on changes in weather over a long period of time. To find climate trends you need to look at how weather is changing over a longer time span. Looking at high and low temperature data from recent decades shows that new record highs occur nearly twice as often as new record lows. Coral reefs, which are highly sensitive to small changes in water temperature, suffered the worst bleaching—or die-off in response to stress—ever recorded in 1998, with some areas seeing bleach rates of 70 percent. Experts expect these sorts of events to increase in frequency and intensity in the next 50 years as sea temperatures rise. Over the past few hundred years, the sun's activity, including the number of sunspots, has increased, causing the world to get warmer. A short Video HOW CAN YOU SAVE THE EARTH? SAVE TREES DO NOT USE CARS FOR TRAVELLING SHORT DISTANCES REDUCE
