Why are temperatures and sea levels not higher?

The same reason that June, when the sun is highest in the sky is not the
hottest month of the year in the UK. Thermal inertia matters.

The oceans have immense thermal inertia and so the response to today's
GHG forcing lags behind. When the oceans do eventually catch up with the
equilibrium conditions appropriate to the present levels of CO2 in the
atmosphere sea levels will be higher. A some future warming is already
locked in even if we stopped the CO2 level from rising tomorrow.

However, as things stand the oceans are chasing a moving target since
CO2 levels and other GHG contributions continue to rise year on year.

What about clouds and cloudiness?
Must play a significant, unspecified as yet, role.
