Evil_Greven posted:In other fun news, even UAH says 2017 was #3 warmest in the satellite record... it wasn't even an El Niño year... The global report is still not out, but U.S. national report was released on Friday. As expected, it ain't pretty: "Based on preliminary analysis, the average annual temperature for the contiguous U.S. was 54.6°F, 2.6°F above the 20th century average. This was the third warmest year since record keeping began in 1895, behind 2012 (55.3°F) and 2016 (54.9°F), and the 21st consecutive warmer-than-average year for the U.S. (1997 through 2017). The five warmest years on record for the contiguous U.S. have all occurred since 2006. Since 1895, the CONUS has observed an average temperature increase of 1.5°F per century. Nationally, the average minimum (low) temperature was 42.8°F, the fourth warmest on record, while the average maximum (high) temperature was 66.4°F, the fifth warmest on record. For the third consecutive year, every state across the contiguous U.S. and Alaska had an above-average annual temperature. Despite cold seasons in various regions throughout the year, above-average temperatures, often record breaking, during other parts of the year more than offset any seasonal cool conditions. Five states – Arizona, Georgia, New Mexico, North Carolina and South Carolina – had their warmest year on record. Thirty-two additional states, including Alaska, had annual temperatures that ranked among the 10 warmest on record." This is only a tiny portion of the report and I encourage you to skim through it at least.

http://onlinelibrary.wiley.com/doi/10.1002/2017GL076079/fullquote:Here we show the climate impacts from removing present day anthropogenic aerosol emissions, and compare them to the impacts from moderate GHG dominated global warming. Removing aerosols induces a global mean surface heating of 0.5-1.1 °C, and precipitation increase of 2.0-4.6 %. Extreme weather indices also increase. We find a higher sensitivity of extreme events to aerosol reductions, per degree of surface warming, in particular over the major aerosol emission regions. Emphasis mine.

Notorious R.I.M. posted:http://onlinelibrary.wiley.com/doi/10.1002/2017GL076079/full Hmm... quote:To keep within 1.5 or 2 degrees of global warming, we need massive reductions of greenhouse gas emissions. At the same time, aerosol emissions will be strongly reduced. We show how cleaning up aerosols, predominantly sulfate, may add an additional half a degree of global warming, with impacts that strengthen those from greenhouse gas warming. This is a bit confusing. Are they saying that reducing aerosols (which are bad, right?) will contribute to global warming?

enraged_camel posted:Hmm... Yes that is what they are saying. Different aerosols have different effects on the environment but the net impact of aerosol reduction is to increase temperatures by ~0.5-1.1C since they have a net cooling effect. One of the hare-brained geoengineering solutions we will inevitably try when poo poo gets really bad is to spray aerosols and pray. This will have unintended consequences.

I feel like it's almost inevitable at this point that wars will be fought over geoengineering schemes. Something like sulfate injection is guaranteed to negatively affect farmland in certain regions of the world and there's no way a country like China is going to sit back and say "yeah, we're totally happy to live with widespread famines so that NYC doesn't sink."

0.5C - 1.1C was within range of what we expected so not really any need to get sadbrains about it. Good to see more research confirming the range though, and the precipitation change is interesting.

Sulfate injection is probably the most disruptive form of geoengineering, and really only gets evaluated because of its low cost. Most of the focus now is on negative emissions technologies. That said, we should probably still inject enough sulfates to compensate for the ones that are removed as coal plants are phased out as part of mitigation. It's not like there's any reason to believe deliberate geoengineering is somehow more dangerous than doing it accidentally - quite the opposite really.

Right, but sulfate injection is a reasonable possibility because it's cheap and easy. Negative emissions technologies are expensive on the scales needed and have no economic justification as anything other than massive projects to combat climate change. Going hugely negative on global emissions is baked into all of the mainstream carbon budgets already in any case.

It's way different optics when it's something everyone is doing because we're crap at judging externalities, than when loving Bangladesh announces it's going to intentionally start releasing gases into the atmosphere to alter the climate on a global scale.

There's a near-earth asteroid going by in the next couple weeks and it makes me wonder: If a medium sized one looks like it might hit, do you think would be better or worse off if we helped it out a little bit? A skyscraper sized rock would supposedly cause 8° of global cooling.

I’d be OK with a giant cloth shade in orbit that can block out some of the sun. Particularly if we can control it, like double the size and cut down on the rays on hot days. It was too sunny today, too sunny.

The Global Climate Report - Annual 2017 is finally out. Excerpt: "The monthly global land and ocean temperatures at the start of 2017 were extremely warm, with the first four months each ranking as the second warmest for their respective months, behind the record year 2016. Of particular note, the global land and ocean temperature for the month of March 2017 was 1.03°C (1.9°F) above the 20th century average—this marked the first time the monthly temperature departure from average surpasses 1.0°C (1.8°F) in the absence of an El Niño episode in the tropical Pacific Ocean. After reaching its peak monthly temperature departure from average in March, temperatures began to slowly decrease in magnitude, ranging between +0.73°C to +0.88°C (+1.31°F to +1.58°F). The remainder months ranked among the four warmest on record, giving way to 2017 becoming the third warmest year in NOAA's 138-year record. The 2017 average global temperature across land and ocean surface areas was 0.84°C (1.51°F) above the 20th century average of 13.9°C (57.0°F), behind the record year 2016 (+0.94°C / +1.69°F) and 2015 (+0.90°C / +1.62°F; second warmest year on record) both influenced by a strong El Niño episode. The year 2017 is also the warmest year without an El Niño present in the tropical Pacific Ocean." There are other things in the report as well, though it isn't as long as the U.S. report.

Some interesting reading here on the effects of Climate Change and the subsequent proposed disaster management for the City of Cape Town, South Africa. The city is rapidly approach Day Zero (currently expected to be 21 April 2018): https://www.dailymaverick.co.za/opinionista/2018-01-22-from-the-inside-the-countdown-to-day-zero What is Day Zero? Dams supplying the city with water are at a crucial low. This crucial low means that dam storage will be at 13.5%. This is when the city will turn off most taps, leaving only vital services with access to water. On Day Zero, Cape Town residents will have to collect water at 200 collection sites or points of distribution in Cape Town. The City estimates that about 20 000 people will be able to collect water per site per day. EDIT: There have a been number of questions in the past in this thread related to how Climate Change would impact people on a day to day basis. The article I linked to provides *some* insight into what happens at a practical level in a scenario where water becomes a scarce resource in a metropolitan area. It's penned by the Western Cape Premier (Helen Zille) who's currently squabbling with the Cape Town mayor (Patricia de Lille) as well as her own party (the Democratic Alliance who runs the province) and the country's ruling party (the ANC). Petty politics aside, it really is worth a read even if you skip the paragraphs where she's playing the blame game. As others have pointed out though, politics will likely always be yet another hurdle we have to take into account when dealing with climate change scenarios and it's thus enlightening in that regard too. vanmartin fucked around with this message at 18:54 on Jan 22, 2018 |
