[Response: Aside from the fact that we've been down all topics on this road about 600 million times now and that the goal of the image was to portray the most
likely temperature history up to the present, and that the increase in standard error going back in time is exactly to be expected as sample size drops, and that your post is off topic, and that you say you're not out to hang Jones while you describe a litany of supposed dis - honesties and cover - ups on his part...
If the goal of the image had been «to portray the most
likely temperature history up to the present» there would have been a single curve, not three!
Not exact matches
«Any life emerging during the Hadean eon
likely needed to be resistant to high
temperatures, and could have survived such a violent period in Earth's
history by thriving in niches deep underground or in the ocean's crust.»
But instead of looking back through
history, he looks ahead to when
temperature and rainfall in different parts of the world are
likely to emerge from current natural variability.
While water molecules were part of the cloud of gas and dust that coalesced into our solar system 4.6 billion years ago, Earth's early
history included scorching
temperatures and little - to - no atmosphere, so it was thought that any water on the planet's surface would
likely have evaporated.
Using models to distinguish between the forcing
histories is thus
likely to require a tighter focus on regional changes, or in climate patterns, more than the just the mean
temperature.
«Based on climate model studies and the
history of the Earth the authors conclude that additional global warming of about 1 °C (1.8 °F) or more, above global
temperature in 2000, is
likely to be dangerous.»
More
likely, Earth's continuing decline in atmospheric
temperatures will resume after the current minor rising blip is over, just as the Sun, our source of heat and light, is signaling and consistent with the continuing cooling of Earth through a significant portion of its long
history.

Based on climate model studies and the
history of the Earth, the Hansen and Sato conclude that additional global warming of about 1ºC (1.8 ºF) or more, above global
temperature in 2000, is
likely to be dangerous.
It is based on a re-written global
history of
temperature by NOAA, not
likely to be either truthful or accurate.
As well as questioning why the «pause» doesn't get a mention in this post on the
history of climate science (the RSS website reference @ 25 is
likely this post by Carl Mears that certainly makes no mention of the «warming hiatus» being «15 to 18 + years» long), DAN SAGE @ 25 talks of two other topics covered elsewhere by SkS - the CO2 - lagging -
temperature saga and the controversal lowering of the bottom of the IPCC ECS range in AR5 (which does not justify talk of ECS being «now... 1degree C, or even a little less», an extremely low value range that has long been proposed by contrarians).
