Yes, global warming is real, supported by overwhelming scientific consensus and extensive evidence like rising temperatures, melting ice, sea level rise, and extreme weather, primarily caused by human activities such as burning fossil fuels. The Earth's average temperature has risen significantly, with the warmest years on record occurring recently, and the rate of warming has accelerated due to increased greenhouse gases from human sources like energy, deforestation, and industry.
Evidence for Global Warming
Rising Temperatures: Earth's average temperature has increased by about 2 degrees Fahrenheit (1 degree Celsius) since the late 19th century, with most warming in the last 40 years.
Ocean Warming & Acidification: Oceans absorb much of this heat, leading to warmer waters, and increased CO2 absorption causes acidification.
Melting Ice: Ice sheets in Greenland and Antarctica are shrinking, and glaciers are retreating globally.
Sea Level Rise: Global sea levels are rising due to melting ice and thermal expansion of water.
Extreme Weather: More frequent and intense heatwaves, droughts, wildfires, and stronger storms are occurring.
Scientific Consensus & Causes
Overwhelming Agreement: Over 99% of climate scientists agree that humans are the primary cause of recent climate change, a consensus level similar to the theory of evolution.
Human Activities: Burning fossil fuels (coal, oil, gas), deforestation, and land-use changes release heat-trapping gases (like carbon dioxide and methane) into the atmosphere, driving the warming.
Key Takeaway
Global warming is a scientifically confirmed phenomenon, with extensive data from sources like NASA, the UN, and the IPCC confirming its reality and human-caused origins.
科学可以始于正确的观察,但也可以毁于错误的解读。
气候变化无论存在与否,都无法得出其根源在于人类活动这一结论啊。
环保教徒就是要硬把两者扯上因果关系,而忽视强大的多的太阳活动周期。
