Is climate change real?

Yes, climate change is real and well-documented by extensive scientific evidence. Here's a summary of what we know:

Key evidence:

•Global average temperatures have risen about 1.1-1.2°C since pre-industrial times

•Ice cores, tree rings, and ocean sediments show clear warming trends

•Arctic sea ice and glaciers are measurably shrinking

•Sea levels have risen roughly 8-9 inches since 1880

•Ocean temperatures and acidity levels are changing

•Extreme weather events are increasing in frequency and intensity in many regions

Scientific consensus:

•The vast majority of actively publishing climate scientists (over 97%) agree that recent warming is primarily caused by human activities

•Major scientific organizations worldwide—NASA, NOAA, the IPCC, national academies of science from numerous countries—all support this conclusion

•This consensus has held up across decades of research and multiple independent lines of evidence

Human causes:

•Burning fossil fuels releases CO2 and other greenhouse gases

•These gases trap heat in the atmosphere

•Deforestation, agriculture, and industrial processes also contribute

What's debated:

•The exact pace of future changes

•Specific regional impacts

•Best policy responses and their costs/benefits

•These are legitimate areas of ongoing research and discussion

If you're looking into specific claims or want to dig into particular aspects (causes, impacts, projections, or policy debates), I'm happy to discuss further.
