Is climate change real?
Yes, climate change is real and is one of the most thoroughly documented phenomena in modern science. Here's a summary of the key evidence and scientific consensus:
The Evidence
Rising global temperatures: Instrumental records show Earth's average surface temperature has increased by over 1°C since the late 19th century, with most of that warming occurring in the past 40 years.
Multiple independent lines of evidence confirm this warming trend:
Scientific Consensus
The overwhelming consensus among climate scientists—based on peer-reviewed research, direct measurements, and physical models—is that:
Major scientific organizations worldwide—including NASA, NOAA, the IPCC (Intergovernmental Panel on Climate Change), national academies of science from numerous countries, and virtually all major scientific societies—affirm this consensus based on decades of data collected through satellites, weather stations, ocean buoys, ice cores, and other instruments.
What's Debated vs. What's Not
While the existence of climate change and human contribution to it is not scientifically contested among climate experts, there are legitimate ongoing discussions about:
