Fixing the Problem

Just to be clear, once some of these climate change problems are set in motion, it is difficult or impossible to stop them. We have started some processes that are essentially irreversible over the next thousands of years, such as the partial melting of Greenland and the West Antarctic. However, we need to do two things to avoid catastrophe and to slow climate change enough to give us time to adapt to the changes:

  1. Reduce global carbon emissions 80% below current levels as quickly as possible (no later than 2050), and related to this,
  2. Rapidly switch the world’s energy supplies over to low/no carbon generating sources, along with substantially improving energy efficiency.

The good news is that we currently have the technology in the form of energy efficiency products, solar photovoltaics, wind turbines and newer, safer nuclear designs to accomplish the 80% reduction.
