Actions against global warming
Several actions have been taken against global climate change and to attempt to reverse it's effects. Since the industrial revolution during the 18th century in which people started to build steam engines and coal trains which started to cause global warming. During the 19th century, scientists discovered a effect caused by burning fossil fuels and using harmful chemicals. The greenhouse effect was discovered in the1820s by John Tyndall and was found that burning fossil fuels warmed up the planet. In 1896, the first global climate change model was made and suggested that burning of fossil fuels by humans have may cause the planet to heat up significantly.
During the late 19th century and early 20th century, the availability of electricity to the general public, the invention of fertilizers and chlorofluorocarbons (CFCs) and better health care accelerate global warming and population growth. In 1930, the opening of the East Texas oil field marked the start of burning cheap oil and coal for electricity, furthering the global warming effect. In 1938, a British engineer, Stewart Callendar, created a model that estimated that the climate could become warmer by 2 degrees Celsius.
During 1960s and the 1970s, the concern for global warming and the greenhouse effect dramatically increased. During this time, several mathematical calculations and analysis were performed, and showed that the Earth was warming up every year. In 1969, the first model that suggested an ice-albedo effect was created. In 1970, the first Earth Day was created and one of the most leading funder of climate change research, the U.S. National Oceanic and Atmospheric Administration, was created. In 1975, it was discovered that chlorofluorocarbons, used in refrigerators and airplanes, caused depletion of the ozone layer. In 1985, scientific studies found that global warming may come twice as fast that expected due to increase in methane (produced by cows) and other harmful gases. In 1990, the Intergovernmental Panel on Climate Change released its first report and said that the world is warming and global climate change seems likely.
In 1997, the first hybrid car was produced by Toyota in Japan. In 2005, the Kyoto protocol was signed by almost all nations in the world with the notable exception of the USA. On February 2009, U.S president Barack Obama discussed with Canadian prime minister Stephen Harper about green energy and how the two nations could reduce their greenhouse gas footprint and what to do about Alberta's oil sands and American coal deposits.
