Is climate change real?

Yes, climate change is real and is one of the most thoroughly documented phenomena in modern science. Here's a summary of what we know:

The Evidence

Warming trends: Global average temperatures have risen significantly since the late 19th century, with the most rapid warming occurring in recent decades. This is measured through thousands of land and ocean temperature stations, satellite data, and weather balloons.

Physical indicators:

The Cause

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

Scientific Consensus

Multiple independent studies analyzing peer-reviewed climate literature have found that over 97% of actively publishing climate scientists agree that recent warming is primarily human-caused. This consensus is reflected in the positions of virtually every major scientific body with relevant expertise.

Why It Matters

The effects include impacts on agriculture, water resources, ecosystems, human health, and increased risks from extreme weather—though the severity varies by region and depends significantly on future emissions trajectories.
