The last CO2 spike comparable to the current one was the PETM about 55.8 million years ago. The rate of carbon increase then appears to be at least 10 times slower than it is now and there was a mass extinction that accompanied it on benthic formaminifera. If the rate today was 10 times slower ocean life would have a much better chance of being able to adapt.

I don't think that's true. On a cloudy but windy night in the desert it doesn't get nearly as cold as on a clear windless night all other things being equal. In fact when I searched for "Desert nighttime cooling" here is the first thing that came up. It basically says under clear low humidity conditions at night radiative cooling is by far the the largest reason for cooling.

1 nanosecond..., honestly, that's typically British. In the US that battery would have been trashed already. The Brits are way too much attached to these long lasting historical figures. And royalty is another example.

Well, there is a light bulb in Livermore, CA that's been burning for 114 years. That hasn't been continuous as there have been some power outages and it's been moved a few times but the Livermore fire department seems pretty attached to it.

As I posted in a previous reply here is more of a big picture look at it:

GISTemp Decadal Global Surface Temperature
(Anomaly from 1950-1981 mean)

Decade_______Anomaly
1884-1893_____-0.26
1894-1903_____-0.25
1904-1913_____-0.40
1914-1923_____-0.28
1924-1933_____-0.17
1934-1943_____+0.00
1944-1953_____-0.03
1954-1963_____-0.02
1964-1973_____-0.02
1974-1983_____+0.10
1984-1993_____+0.24
1994-2003_____+0.46
2004-2014_____+0.59

As you can see the temperature rise from 1904-1903 to 2004-2014 is 0.99 degrees. Looking at it in decadal slices takes out the noise of year to year variability.

In the "big picture", there aren't many effective levers to pull to solve the warming problem, and the cost of pulling them is higher than the benefit.

Sez you. I've seen plenty of analyses from others including economists that say otherwise. At the rate we're going the "small amount" of warming over a few hundred years is still 10 times faster than the warming at the end of the last glaciation (ice age) and will cause sea level rise in 10's of feet.

I would probably vote no because solar and wind power are cheaper than nuclear. I'm not against nuclear power for environmental reasons although it has its problems there but because they are expensive. If someone develops inexpensive modular nuclear power units I'd be willing to see them deployed.

The 19334-1943 mean was the same as the 1951-1980 mean so 2014 is equally unusually hot (and in case you're going to ask what about 1930-1933 the 1924-1933 mean was -0.17 compared to the 1951-1980 mean). 10,000 years ago was at the tail end of the last glaciation (ice age in the common vernacular). From proxy research it appears to at most been about the same as the 1951-1980 average although of course the error margin is larger.
