What if we do Nothing?

Most projections of future impacts do not address what could happen if warming continues beyond 2100, which is inevitable if steps to reduce emissions are not taken, or if the rate of change accelerates. Furthermore, the longer warming persists and the greater its magnitude, the greater the risk of climate “surprises” such as abrupt or catastrophic changes in the global climate.

Even if we are able to reduce emissions of greenhouse gases, some further warming is unavoidable. We must plan and take action now to adapt to the changes we will face as our climate changes.
