Tutorial for Science Journalists regarding "global warming" AKA "climate change" AKA "climate disruption: A few questions serious journalists might want to ask instead of just cut and pasting press releases from activists. 1 Did the oceans contribute to warming? If the oceans recently cooled the air, couldn’t they have warmed it earlier (pre the pause)? If so, how have the IPCC models been changed to reflect this increased effect of natural variability?Surely the effect of CO2 is made smaller by this admission? 2 How accurate are those measurements? How many degrees has the ocean actually warmed? Is our equipment accurate enough to measure that? (Don’t get fooled by unrealistic statistical assumptions, such as that all of the ocean simultaneously warms by the same amount –that amount being “the global warming”.) How did we measure global ocean temperature 50 years ago? What kind of data is was available for water below 700m in the 1960s? 3 How does this tell us the cause of the warming? Wouldn’t any cause of warming cause the oceans to warm — how do we know it was CO2 rather than something else? (following on) So are those the same models that failed to correctly forecast global surface temperatures, tropospheric temperature and humidity, antarctic sea ice, tropical storms, and regional rainfall? (following on) Yes skeptics agree that CO2 warms the planet, they question the amount of amplification by feedbacks in the models. What empirical evidence is there that the model’s assumptions about clouds and water vapor feedbacks are correct? Which piece of equipment was that measured on? (No, a computer is not an instrument that measures the atmosphere). 4 The numbers don’t match: How many Watts per meter2 (in radiative imbalance) do these extra Joules of energy imply? Don’t these ocean heat figures actually support the skeptics claim that effect of the CO2 is minor and the models are overestimating warming by a factor of at least two? joannenova.au/2013/09/ipcc-in-denial-just-so-excuses-use-mystery-ocean-heat-to-hide-their-failure/
