Global Warming's Terrifying New Math

If these trends continue – and there’s no reason to expect that they won’t – the next 40 years will see almost all vertebrate species extirpated.

Read in the LA Times this morning that Alaska didn't have a single day in 2014 where the temperature was below 0 F (-17.8 C), which has never happened before.

NB: that record refers to Anchorage AK, not the whole state.

OK, that makes more sense. The trend still holds.

Wish Godzilla would just come and kill us all already tbh

Also I think I saw that Los Angeles just had its first day where the daily high was under 60 F in about a year.

For fun!

2014 officially the hottest year on record, US government scientists say

Cheer up, Ned.

Anticipate Pope Francis's instructions on climate change will have about as much impact as every pope's instructions on abortion since 1869.

Uh plenty of people follow the pope's instructions on abortion. Lots of people actually.

But the proportion that don't is about the same, or greater, than non-Catholics.

America is not the world

less than 8% of the world's Catholics are American

I think more Catholics much less attentive to monogamy

let's stay focused here people.

this debate about the pope's influence on climate change is going to be full of thrills spills and chills *bookmarks*

your like Stadler minus Waldorf & jokes

best compliment i've had in weeks

There really are stats along religious lines for other countries, but predominantly Catholic nations have if anything higher rates.

What the papal policy statements do offer is political backup for natural constituencies supporting a policy, though they may have little effect in individual actions. I'm not sure the natural constituency for conservation and green energy is anywhere as potent as that for defenders of "conservative values".

She does have a sense of humor. Biden arrives early...

Sherwood, S. C., & Huber, M. (2010). An adaptability limit to climate change due to heat stress. Proceedings of the National Academy of Sciences, 107(21), 9552-9555.

Because combustion of all available fossil fuels could produce 2.75 doublings of CO2 by 2300 (5), even a 4.5 °C sensitivity could eventually produce 12 °C of warming.

We conclude that a global-mean warming of roughly 7 °C would create small zones where metabolic heat dissipation would for the first time become impossible, calling into question their suitability for human habitation. A warming of 11–12 °C would expand these zones to encompass most of today’s human population. This likely overestimates what could practically be tolerated: Our limit applies to a person out of the sun, in gale-force winds, doused with water, wearing no clothing, and not working.

Bacteria will inherit the earth.

Schlenker, W., & Roberts, M. J. (2009). [Nonlinear temperature effects indicate severe damages to US crop yields under climate change](http://www.pnas.org/content/106/37/15594.short). Proceedings of the National Academy of sciences, 106(37), 15594-15598.

The United States produces 41% of the world's corn and 38% of the world's soybeans. These crops comprise two of the four largest sources of caloric energy produced and are thus critical for world food supply. We pair a panel of county-level yields for these two crops, plus cotton (a warmer-weather crop), with a new fine-scale weather dataset that incorporates the whole distribution of temperatures within each day and across all days in the growing season. We find that yields increase with temperature up to 29° C for corn, 30° C for soybeans, and 32° C for cotton but that temperatures above these thresholds are very harmful. The slope of the decline above the optimum is significantly steeper than the incline below it. The same nonlinear and asymmetric relationship is found when we isolate either time-series or cross-sectional variations in temperatures and yields. This suggests limited historical adaptation of seed varieties or management practices to warmer temperatures because the cross-section includes farmers' adaptations to warmer climates and the time-series does not. Holding current growing regions fixed, area-weighted average yields are predicted to decrease by 30–46% before the end of the century under the slowest (B1) warming scenario and decrease by 63–82% under the most rapid warming scenario (A1FI) under the Hadley III model.

no scientific evidence

http://www.independent.co.uk/environment/gulf-stream-is-slowing-down-faster-than-ever-scientists-say-10128700.html

Well, there's no scientific evidence that the Gulf stream moderates the climate in Britain as asserted in the headline and article. It's heat from the North Atlantic and general hot air currents from the South that are responsible.

The thermohaline / Atlantic meridional overturning circulation has a huge influence on NW European climates, and for a glimpse of life without it, look to the Younger Dryas (much as the PETM offers a template for rapid global warming). During the Younger Dryas, mean annual temperatures in the UK dropped to −5 °C.

Whether this might locally mitigate global warming harms is an open question.

That's an earlier incarnation of the fine company that brought us the Exxon Valdez.

Ah -- that's the Esso logo on the right, isn't it?

Esso, yes - the phonetic transmogrification of Standard Oil, the trust you'd most love to bust in the chops.

a brief, readable primer on permafrost:

http://www.washingtonpost.com/news/energy-environment/wp/2015/04/01/the-arctic-climate-threat-that-nobodys-even-talking-about-yet/

i'm sure ilxors reading this thread are familiar with the issue but most people aren't. if you're not, take 5 minutes and read it!

I've been bumming myself out about permafrost ever since I first bookmarked this thread.

it is a total bummer among other feedback loop bummers. also the ice-albedo feedback loop.

ugh. even just typing the words shuts me down

Have any of you seen the documentary Cowspiracy? Saw it recently and while it was tonally kind of grating, it did seem pretty legit (put simply: animal agriculture is a much bigger factor in climate change than carbon; also water usage, etc.), but I am not well-versed in the science of CC and don't want to fall for shoddy vegan propaganda.

dying to watch anything called Cowspiracy so should maybe hold back from engaging til i've seen it, but, just to offer the hot layman's take everyone's dying to hear: i think that the methane generated during farming is a bigger contributor than carbon emissions is settled, right? the permafrost article just linked mentions the additional problems of methane over co2.

yours, belligerent vegetarian, canada

ice-albedo feedback loop.

yep, those black particles are screwing everything up
