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. Average global surface temperature has increased by more than 1°C since the late 1800s, with most of that warming occurring in recent decades.

Multiple independent lines of evidence confirm it:

The Cause

The overwhelming scientific consensus—backed by organizations like NASA, NOAA, the IPCC, and virtually every major national science academy in the world—is that the current warming trend is primarily caused by human activities, especially:

These activities release greenhouse gases (mainly CO₂ and methane) that trap heat in the atmosphere, a well-understood physical mechanism dating back to 19th-century physics.

Scientific Consensus

Studies analyzing peer-reviewed climate science consistently find that 97-99%+ of actively publishing climate scientists agree that human-caused climate change is happening. This isn't a "50/50 debate" in the scientific community—it's about as close to settled science as complex Earth systems research gets.

If you're looking for the latest data (e.g., 2024-2026 temperature records, recent IPCC updates, or current policy debates), I'm happy to look that up for current specifics. Let me know if you'd like me to search for anything more recent or specific!
