đ The Earth's climate has fluctuated for millions of years, but in the last century, human activity has caused a rapid rise in temperature known as global warming.
đ„ The burning of fossil fuels like oil and coal releases greenhouse gases, which trap heat near the Earth, leading to the greenhouse effect.
âïž The sun radiates energy to the Earth, and naturally occurring gases in the atmosphere absorb some of this energy, causing a trapping of heat.
đ The greenhouse effect is being intensified by the extra greenhouse gases released by humans, resulting in global warming.
đ Evidence for global warming includes a recent string of very warm years, with 1998 being the warmest year in history.
âïž Arctic sea ice has declined about 10 percent in the last 30 years, indicating the impact of global warming.
đ Global warming can lead to rising sea levels, changes in weather patterns, severe droughts, and species extinction.
đĄïž Climate models predict varying impacts of rising temperatures, with some suggesting subtle changes and others indicating more severe consequences.
đȘ Organizations advocate reducing greenhouse gas emissions through energy-saving practices and lifestyle changes to mitigate the impact of global warming.
