Climate Change

Status: public · Confidence: medium (0.78) · Basis: verified_sources

## TL;DR

Climate change is the long-term shift in climate conditions driven in the modern era primarily by human greenhouse gas emissions. The public claims in this article are limited to IPCC AR6 synthesis materials: human activities have caused global warming, observed impacts are already widespread, and the 2023 synthesis report summarizes the Sixth Assessment Report cycle.

## Core Explanation

Greenhouse gases such as carbon dioxide and methane trap heat in the Earth system. The IPCC AR6 synthesis materials describe current global warming as human-caused and connect it to observed changes in weather and climate extremes across regions.

The practical significance is that climate change is not just a future projection. It is already visible in observed hazards and impacts, while future risk depends strongly on emissions pathways, adaptation choices, and how quickly warming is limited.

This concise article avoids unsupported numeric updates and points readers to the IPCC source material for detailed regional findings, uncertainty ranges, and scenario analysis.
