What are the different emission scenarios?

The extent and severity of global warming depends on the rate at which human activities, such as the burning of fossil fuels, continue. Rate of population growth, economic development will be crucial. How much and how quickly heat-trapping emissions accumulate in the atmosphere and how the climate responds to these emissions will determine the projected climate change.

Cal-Adapt provides access to projections that are derived from two differentemissions scenarios .

As this figure shows, CO2 emissions from human activities (such as the burning of fossil fuels) were negligible until around the so-called industrial age starting in the 1850s.
