Is climate change real?

Yes, climate change is real—this is one of the most well-established findings in modern science, backed by an overwhelming scientific consensus.

Here's what we know with high confidence:

It's happening
Global average temperatures have risen significantly since the pre-industrial era (roughly the late 1800s), with the most rapid warming occurring in recent decades. This warming is documented through multiple independent lines of evidence: thermometer records, satellite data, ocean temperature measurements, ice core samples, and shrinking glaciers and ice sheets.

Humans are the primary cause
The scientific consensus—supported by major national academies of science around the world, NASA, NOAA, and international bodies like the Intergovernmental Panel on Climate Change (IPCC)—is that human activities, primarily the burning of fossil fuels (coal, oil, and gas), are the dominant driver of the observed warming since the mid-20th century. This happens because burning fossil fuels releases greenhouse gases like carbon dioxide and methane, which trap heat in the atmosphere.

Key evidence includes:

Scientific consensus
Multiple studies analyzing peer-reviewed climate science literature have found that the vast majority (97% or more) of actively publishing climate scientists agree that recent warming trends are extremely likely due to human activities. Major scientific organizations worldwide, including the American Association for the Advancement of Science, the National Academy of Sciences, and equivalent bodies in dozens of other countries, have issued statements affirming this consensus.

While there's legitimate scientific debate about specific details—like precise regional impacts, exact timelines for certain tipping points, or the best policy responses—the fundamental reality that the climate is warming and that human activity is the primary cause is not seriously contested within the scientific community.
