If by norm you mean the slope, yes. If you meant the y intercept, no. Soon it will be hotter. In Karachi and where you live too.

To change the slope, exactly two things work: reducing our consumption and reducing our birth rate. Mechai Viravaidya in Thailand showed how to reduce birth rate in the opposite of China's One Child policy or eugenics -- that is, voluntary, noncoercive, even fun -- as did Costa Rica, Iran, and several other countries. Most Americans can improve their quality of life by lowering consumption. I reduced mine over 90% with just life improvements. I estimate most Americans can reduce theirs 80% or more without sacrifice, just improvements. The most polluting can probably reduce theirs 99%.

Systemic change begins with personal transformation. Government and corporations will follow individual action, as they historically have. Personal transformation enables us to lead others. Leading others has the biggest effect because it multiplies.
