What is the increase in average global temperature recorded since 1900?

The increase in average global temperature recorded since 1900 is approximately 0.7 degrees Celsius. This figure is based on extensive climate data that reflects rising temperatures due to various factors, including human activities like the burning of fossil fuels and deforestation, which have led to increased greenhouse gas emissions.

This 0.7-degree increase is significant because it highlights the gradual warming trend that impacts weather patterns, sea levels, and ecosystems worldwide. It serves as a benchmark for understanding climate change and is often cited in scientific reports and discussions about climate action and environmental policy.

While other options may suggest larger increases, the consensus from climate studies indicates that the 0.7-degree figure is the most accurate representation of the change in average global temperature over the past century.
