Study Notes

Earth's climate has fluctuated for 2.5 million years, but in the last century, the planet's temperature has risen unusually fast by about 1.2 to 1.4 degrees Fahrenheit, attributed to human-driven global warming.
Human activities, such as burning fossil fuels like oil and coal, have released significant amounts of greenhouse gases like carbon dioxide into the atmosphere, intensifying the natural greenhouse effect.
Evidence of global warming includes a recent string of very warm years, with 1998 being the warmest measured year and 2005 coming in second, along with record levels of greenhouse gases in the past 420,000 years and a significant decline in Arctic sea ice.
Industrialized nations and developing countries contribute to the rising concentration of greenhouse gases, with predictions of a temperature increase of about two to 10 degrees Fahrenheit by the end of the century, leading to uncertain impacts on the planet like rising sea levels, changing weather patterns, and increased risks of extreme events.
Organizations advocate reducing greenhouse gas emissions to mitigate the impact of global warming, and individuals can contribute by conserving energy, using energy-efficient light bulbs, and reducing car usage to help lower the earth's temperature in the future.
