Is climate change real?

Yes, climate change is real, and this is one of the most well-established findings in modern science. Here's what we know:

The Evidence

Global temperatures are rising. Multiple independent datasets from NASA, NOAA, the UK's Met Office, and others show a clear warming trend since the late 19th century, with the most rapid warming occurring in recent decades.

Multiple lines of evidence converge:

The Cause

The overwhelming scientific consensus—supported by national academies of science around the world and major scientific organizations—is that the current warming trend is primarily caused by human activities, particularly the burning of fossil fuels (coal, oil, gas), which releases greenhouse gases like CO2 and methane. These gases trap heat in the atmosphere, enhancing the natural greenhouse effect.

Scientific Consensus

Studies of peer-reviewed climate science literature consistently find that 97% or more of actively publishing climate scientists agree that human-caused climate change is happening. Major bodies like the Intergovernmental Panel on Climate Change (IPCC), which synthesizes thousands of studies, have concluded with very high confidence that human influence has warmed the planet.

If you're interested in specific aspects—like recent climate data, policy responses, or particular impacts—I'm happy to dig into those with you.
