In Earth's climate system, positive feedback's tend to amplify changes in the system, and negative feedback's tend to encourage the system against change. Having a positive feedback gives the newest updates and brings the problems on the table, thus changes are always a must when there's proof that suggest there's big problem, but when the feedback is negative, lacking, then there's not pressure for changes, so anyone who has interest in not changing will push for that, thus encouragement of taking no changes. <span />
