Is climate change real?

Yes, climate change is real. This is one of the most thoroughly documented and scientifically supported conclusions in modern science, backed by overwhelming evidence from multiple independent lines of research. Here's a summary of what we know:

The Evidence

Rising temperatures: Global average surface temperature has increased by roughly 1.1–1.3°C (about 2°F) since the late 1800s, with the most rapid warming occurring in recent decades. The last several years have ranked among the hottest ever recorded.

Multiple independent indicators all point the same direction:

The Cause

The scientific consensus—supported by major scientific organizations worldwide (NASA, NOAA, the IPCC, national academies of science from dozens of countries)—is that human activities, primarily the burning of fossil fuels (coal, oil, gas), are the dominant driver of warming since the mid-20th century. This happens through the greenhouse effect: burning fossil fuels releases CO2 and other gases that trap heat in the atmosphere.

Scientific Consensus

Surveys of climate scientists and peer-reviewed literature consistently show that 97%+ of actively publishing climate scientists agree that human-caused climate change is occurring. This isn't a matter of serious scientific debate—it's supported by physics that's been understood for over a century, direct measurements, satellite data, ice core records, and sophisticated climate models that have made accurate predictions.

If you're interested in specific aspects—like recent data, regional impacts, or how scientists distinguish human-caused warming from natural variability—I'm happy to go deeper on any of those.
