Yes, Climate Change Is Real

This is one of the most well-established findings in modern science, supported by multiple independent lines of evidence:

Key evidence includes:

•Temperature records — Global average temperatures have risen about 1.1-1.2°C since pre-industrial times, with the last decade being the warmest on record

•Ice cores and glaciers — Arctic sea ice, glaciers, and ice sheets are shrinking measurably over time

•Sea level rise — Oceans have risen roughly 8-9 inches since 1880, and the rate is accelerating

•Ocean chemistry — Oceans are becoming more acidic due to absorbing excess CO2

•Extreme weather patterns — Changes in frequency/intensity of heatwaves, droughts, and storms

Scientific consensus:

•Major scientific organizations worldwide (NASA, NOAA, IPCC, national academies of sciences from dozens of countries) agree on this

•The overwhelming majority (97%+) of actively publishing climate scientists agree that recent warming is primarily driven by human activities, especially greenhouse gas emissions from fossil fuels

What's actually debated:
The scientific debate isn't about whether climate change is happening, but focuses on:

•Precise regional impacts and timelines

•Best policy responses

•Economic tradeoffs of different solutions

•Specific climate sensitivity figures

If you're encountering claims that dispute this, I'm happy to discuss specific arguments you've heard—there's often a mix of legitimate scientific uncertainty (on details) and misinformation (on the core facts) circulating in public discourse.
