All three of these show temperatures before AGW began. If the Earth is "supposed to be" a temperature, it is the temperature it had then.
Sea level rise, increasing temperatures, ice losses reducing drinking water supplies, crop failures, extreme weather events, ocean acidification, dramatically accelerated extinction rates.
It is NOT normal for CO2 or temperatures to increase as quickly as they have over the last 150 years. CO2 is higher and increasing faster than it has in the last 3 million years. The Earth's current temperature is likely the hottest the planet has been in over 2 million years and it is still climbing at an unprecedented rate.
