I would say it's hard to quantify a changing system. If you take just the increased average solar irradiance since 1900, realize the oceans cover 71% of the surface, and that they absorb more than 90% of the sun's energy, how can someone not realize that this latent heat not only changes the equation, but has a lag time too. Our solar irradiance has increased by approximately 0.2% since the Maunder Minimum to 2000 (
NOAA-Judith Lean 2004). The annual change from 1700 to 2000 is 0.235% and the 11 year average for 1700 to 2000 is 0.196%. This latent energy will continue to change our climate for at least decades and likely for centuries to come.
Keep in mind we calculate temperatures for science in the Kelvin scale. a 0.2% increase for an approximate 288 K adds 0.576 degrees. That alone is more than half the warming claimed since industrialization started. Now the average increase for the 300 years is only an average 0.08%, but when you add 71% x 90% x total annual energy of 174 petawatts for 300 years... If the oceans have retained all this increased energy, then it is about 26.7 petawatts. 15.3% of the annual energy. Now in reality, maybe only half to quarter of this stays latent with the circulation of the oceans, and the rest is shorter term lag in the surface oceans. There is no way mankind has of reducing the warming effect on the earth. Nature has to dissipate this energy herself. This is a major reason she has an elevated temperature. She is doing just that.
A very biased article if you ask me.
Why do they deny the effects of the solar increases starting about 1900? This would definitely account for what they attribute to other unknown things.
Warmer water means more outgassing in the equatorial regions and less absorption in the polar regions. This is simple equilibrium that needs no source. If you agree the oceans have warmed, then you must believe this is true, unless you refute the associated sciences that are well understood.
