New Sclerosponge Temp Reconstruction Indicates We've Already Experienced 1.7C of Warming

You need help. Call your family physician and ask them to recommend a good mental health facility that accepts your insurance. Make an appointment, KEEP the appointment and LISTEN to what the doctor has to say.

Really.
Crick, you need help. Not from a physician, but from someone who knows how to participate in a message board.
 
The carbonate skeletons of long-lived sponges give excellent sea surface temperature values prior to their widespread instrumental measurement. A reconstruction using them for SST values shows greater post-industrial warming than prior reconstructions

"Anthropogenic emissions drive global-scale warming yet the temperature increase relative to pre-industrial levels is uncertain. Using 300 years of ocean mixed-layer temperature records preserved in sclerosponge carbonate skeletons, we demonstrate that industrial-era warming began in the mid-1860s, more than 80 years earlier than instrumental sea surface temperature records. The Sr/Ca palaeothermometer was calibrated against ‘modern’ (post-1963) highly correlated (R2 = 0.91) instrumental records of global sea surface temperatures, with the pre-industrial defined by nearly constant (<±0.1 °C) temperatures from 1700 to the early 1860s. Increasing ocean and land-air temperatures overlap until the late twentieth century, when the land began warming at nearly twice the rate of the surface oceans. Hotter land temperatures, together with the earlier onset of industrial-era warming, indicate that global warming was already 1.7 ± 0.1 °C above pre-industrial levels by 2020. Our result is 0.5 °C higher than IPCC estimates, with 2 °C global warming projected by the late 2020s, nearly two decades earlier than expected."

The "warming" started in the 1860's? Really??

Traditional biomass makes up half the energy consumption by source until maybe 1930

If you're wondering whatever happened to Bernie Madoff's accountant, he's obviously working for the AGWCult
 
The AGWCult suggests that clam shells can give you reading accurate to a 7 hundreds of a degree over 150 years, but ask them for the demonstrated temperature increase by increasing CO2 from 280 to 400PPM they respond with charts, card tricks, REEEEEEEEEEEEEEEEEEEEs, but never a number

why did the one mile ices sheet melt over Chicago?
