Is climate change real? I'll pull the latest scientific evidence to answer you.
Yes, according to the overwhelming scientific evidence and consensus, climate change is real.
Scientific Consensus
•There is unequivocal evidence that Earth is warming at an unprecedented rate. Human activity is the principal cause.
•The vast majority of actively publishing climate scientists – 97 percent – agree that humans are causing global warming and climate change
•A 2019 review of scientific papers found the consensus on the cause of climate change to be at 100%, and a 2021 study concluded that over 99% of scientific papers agree on the human cause of climate change
•The Intergovernmental Panel on Climate Change (IPCC) says there is 95 percent certainty that humans have caused most of the warming of the planet's surface that has occurred since the 1950s
•The IPCC report confirms that it is extremely likely (95-100% probability) that most of the warming since 1950 has been due to human influence
•The IPCC also concluded that warming of the climate system is unequivocal and human influence on the climate system has been the dominant cause
Evidence
NASA and other scientific agencies point to multiple independent lines of evidence:
•While Earth’s climate has changed throughout its history, the current warming is happening at a rate not seen in the past 10,000 years.
•According to the Intergovernmental Panel on Climate Change (IPCC), "Since systematic scientific assessments began in the 1970s, the influence of human activity on the warming of the climate system has evolved from theory to established fact."
•The current warming trend is different because it is clearly the result of human activities since the mid-1800s
•While natural variability plays some part, the preponderance of evidence indicates that human activities—particularly emissions of heat-trapping greenhouse gases—are mostly responsible
Specific observed changes include:
•The planet's average surface temperature has risen about 2 degrees Fahrenheit (1 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide emissions into the atmosphere and other human activities
•According to an ongoing temperature analysis led by scientists at NASA's Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by at least 1.1° Celsius (1.9° Fahrenheit) since 1880
•Most of the warming occurred in the past 40 years, with the seven most recent years being the warmest
•The planet's average surface temperature has risen about 2 degrees Fahrenheit (1 degrees Celsius) since the late 19th century
Other compelling evidence cited by NASA includes:
•The ocean has absorbed much of this increased heat, with the top 100 meters of ocean showing warming and Earth stores 90% of the extra energy in the ocean.
•The Greenland and Antarctic ice sheets have decreased in mass - Greenland lost an average of 279 billion tons of ice per year between 1993 and 2019
•Global sea level rose about 8 inches (20 centimeters) in the last century
•Both the extent and thickness of Arctic sea ice has declined rapidly over the last several decades
In summary, the scientific community considers it established fact that the climate is warming and that human emissions of greenhouse gases are the dominant cause, based on direct temperature measurements, satellite observations, ice cores, ocean measurements, and climate modeling.
