This thread is good when it talks about things like carbon capture and what it would actually take and why it won't work as a license to keep polluting, or actual scientific projections on what's going to happen. It's real bad when it gets to the apocalypse fantasy circlejerk though, and it does that all the time.

Would you like to be enraged by climate denialism today? Boy, have I got the article for you! Australian natural disasters minister David Littleproud: 'I don't know if climate change is manmade' It has everything: outright denialism, pretending the science isn't sure about the cause of climate change, 'it has always been changing', claiming we can't know that climate change caused a particular fire, accusing the Greens of politicizing a tragedy and even supporting a 'sensible' response to climate change through [checks notes] supporting the production of more coal and gas. Somehow, Australia's government always manages to be worse than even the Trump administration when it comes to climate change.

I never understood the argument. Ok, let's say it's not manmade, and it is bound to happen anyway. We loving know from science what is needed to lessen the impact. Why don't we do it then?

Although I am ultimately very pessimistic, I do think it's worth considering tipping points: the physical systems of the Earth have them, but civilization does as well; it feels as though nothing will ever change, but there will be a moment when the reality of the situation comes crashing home. It's inevitable, and I think it will happen soon, but the question is whether it will be soon enough.

In Europe it kind of is already, green parties are growing at an incredible rate and are enjoying a lot of support, they are the biggest single-issue parties in general. Such a shame that a lot of them consider themselves to be politically centrist, and many are happy with Macron-style economic incentives for capitalists which at this point, yeah is much too little too late. Read a fresh report today that basically is capitalism's answer.html https://eto.dnvgl.com/2019 The tldr is we're gonna blow past 2.0 to 2.5 degrees for sure due to "lack of political will" (to create incentives for electrified industry, electric cars), oil needs to mostly end in the early twenties, we gotta get 1500 billion dollars investment in the energy grid each year, need octuple the rate of renewable energy development by 2030 and we need to increase battery production by the low low amount of 50 times before 2030. Yeah looks like we're saved guys. Globalist capitalism has got this in the bag! Thank gently caress, I was getting worried there for a second.

Martian posted:Somehow, Australia's government always manages to be worse than even the Trump administration when it comes to climate change. If you're Australian, you can take comfort in the existence of Alberta, where the leadership won't even admit climate change is happening. As one of only two land-locked Canadian provinces they've been tantrumming for a while about the lack of enthusiasm for pipelines they feel they need to get even more diluted bitumen from their tar bitumen sands to all the overseas markets wetting themselves at the possibility of buying even more lovely heavy oil-like product. Latest move by their government is to set up a commission of inquiry into foreign funding of environmental movements opposed to pipelines and oil tankers. As part of his inquiry the commissioner will be travelling to B.C. to gather evidence that those of us opposing even more dilBit tankers in our waters are only doing so because of all that sweet, sweet Sierra Club money. Or maybe Soros money - I dunno, have to check the signature on the last cheque. If Alberta ever does carry through with threats to secede from Canada Australians can rejoice that there is now a country with a government dumber than theirs. At least despite a lack of rain it's been a mild, cloudy summer and neither province is burning down as fast as usual over the last five years. Still time for a dry autumn though. The soil is insanely dry atm. e: And now the premier of Alberta is suggesting that Putin might have the right idea for dealing with environmentalists. Sorry Australia, you've have to step up your game if you want to regain your title. Hexigrammus fucked around with this message at 18:05 on Sep 11, 2019 |

I don't want to take anything away from the sterling effort Alberta's leaders are putting in, it's truly impressive. But if you think Australia is going down without a fight you should think again. Merely two days ago the minister for water resources, drought, natural disaster and emergency management, David Littleproud, has said that he doesn’t “know if climate change is manmade”. Littleproud’s position was supported by the Nationals deputy leader, Bridget McKenzie, the minister for resources and northern Australia, Matt Canavan, and the environment minister, Sussan Ley, all of who denied knowledge of or downplayed the link. This at a time when bushfire season has started two months early, in winter, in subtropical regions that don't normally burn and most of New South Wales and Queensland are experiencing a severe drought. Don't come play with the big boys if you don't expect a challenge. for reference https://www.theguardian.com/australia-news/2019/sep/10/david-littleproud-australian-minister-disaster-climate-change-man-made https://www.theguardian.com/comment...-climate-crisis

Hi guys, I am a high school maths high school teacher and was interested in doing the climate strike next Friday (20 Sep) but have decided that a far more impactful thing to do than striking would be to spend the day teaching about climate change, the mathematics of it, etc. Has anyone done this for high school students in a positive (ie not boring) way?

As someone said - either in this thread or the other, a good way to explain why 2C is as bad as 3C+ is that if your body temperature permanently increased two degrees (either in C or F), you'd be dead.

Tab8715 posted:how difficult and expensive would it be to grow something like tomatoes in a partially indoor climate controlled setting? I'm not a commercial grower so I really don't know how it's done at scale, but I can say that an amateur level it's much easier to use indoor environments to protect against the cold than it is to protect against the heat. Greenhouses are generally pretty cheap and easy to set up if you aren't growing a ton of crops, but their main purpose is to keep crops warm. Cooling is usually semi-passive and the intent is to keep your plants from overheating when it's very warm out, because the greenhouse environment will be warmer than the outdoor environment (which is generally the point). Actively cooling a greenhouse for personal use would be tough and I don't even know how you'd go about doing it. If it's somehow just flat out too hot for tomatoes to grow in the summer, you'd be better off using a greenhouse to extend your growing season into the fall when it's cooler and taking advantage of the greenhouse to keep temperatures up rather than trying to beat the heat.

Fans to fan out heat and lights are the most power intensive its easy as gently caress.The lights will keep everything nice and warm a controlled environment allows better growth than outdoors, You can grow watermelons indoors easy. Labor time dependent on size of operation. For example yoi could grow a tomato plant in a 32 gal rubbermade container in your closet with CFL bulbs. Its ghetto but itll work. You could scale up and do 10 plants and yarn them for maximun light penetration. It all is dependent on your plan. I own a 5,000 sqft warehouse with 4 indoor growing rooms . Really a simple process if your smart enough to automate.

I'm not a teacher, but maybe some stuff like this would serve as ideas. Calculating CO2 mass in the atmosphere: Earth's atmosphere: 5,148 trillion tonnes. Mean molar mass of the atmosphere: 28.97g/mole Carbon Dioxide (CO2) molar mass: 44.0095 g/mole Atmospheric CO2 parts per million (ppm), March 2017: 407.05 ppm Atmospheric CO2 mass, March 2017 (atmosphere mass * (carbon dioxide molar mass / atmosphere molar mass) * CO2 ppm): 3.18 trillion tonnes of CO2 Calculating CH4 mass in the atmosphere: Earth's atmosphere: 5,148,000 gigatonnes (Gt) = a Mean molar mass of the atmosphere: 28.97g/mole = b Methane (CH4) molar mass: 16.04 g/mole = c Atmospheric CH4 ppm, 1984 annual mean: 1.64456 ppm = d Atmospheric CH4 mass, 1984 (a * (c / b) * d): 4.69 Gt = e The equation for Stefan-Boltzmann is E = σT^4 E = energy flux (W/m^2) σ = 5.67×10^-8 W/m^2 T = temperature (in Kelvin) Incoming solar power averaged over the Earth's surface with its current albedo is ~240 W/m^2: ~240 W/m^2 = 5.67x10^-8 W/m^2 * T^4 T = (240 W/m^2 / 5.67x10^-8 W/m^2)^(1/4) T = ~255K But wait, you say - the Earth's surface is ~288K not ~255K: E = 5.67x10^-8 * (288K)^4 E = ~390 W/m^2 255K is the average temperature of the Earth's atmosphere (it can be really cold depending on altitude). Some really old oil post: The U.S. oil consumption is around 19 million barrels a day (circa 2011). This is pretty large, about 22% of global oil consumption. It's sometimes hard to visualize just how much that is, though. At a little under 160 liters per barrel, that's over 3 billion liters a day, or over 3 million cubic meters of oil. This works out visually to over three square km covered a meter deep in oil. So, that's about 1100 square km annually to the depth of a meter, or 1.1 cubic km of oil. Now, the average weight of crude oil is around 0.825 kg/liter for a total approaching 2.5 billion kg daily (the average composition by weight is about 84% carbon, so that's over 2 billion kg of carbon daily), and there's an estimated (in 2000) 230 trillion kg (230 gigatonnes) of crude oil in the earth. So, it'd take 92,000 days for the U.S. to consume all the world's oil at 2011 rates. 250 years seems like a lot, but remember one little thing - the U.S. only accounts for 22% of global oil consumption. This cuts the figure to 70 years... from 2000... assuming no increases/decreases in consumption. 9/11 side note, since I saw Rime coming to the realization back in 2017 looking at these old posts, 9/11 caused grounding of commuter flights which altered global dimming that we had inflicted upon ourselves and increased the day/night variation in temperatures (dimming moderates temperatures).

The strike shows solidarity with a huge range of people who are probably very new to activism. Being another body in this context means that you personally demonstrate the power of collective action in a way that simply plying your trade can’t. Go strike. All of you. Walk out of your loving jobs on the 20th. Unless you’re in Canada, then you do it on the 27th because we’re loving dumb.

We're past the point where it makes sense to really try to convince people or even teach them the science. Mainstream media is largely on board with the messaging of "climate change is real, it's bad, we're hosed." The only people you're fighting against now are the ones that are willfully ignorant, and even when it comes to kids you're going to hit a wall of diminishing returns since their parents are going to push back hard. The best you can do for these kids is to show that direct, collective action can make a meaningful difference and cause people to actually sit up and notice. I have a feeling you're going to eat a lot of negative feedback no matter what though.

Teaching people about global warming and science at face value is overall a good thing. All of the leading climate scientists (Hayoe, Michael Mann, Etc.) regularly speak about global warming to future PhDs to grade school children. They know we’re going beyond 2C and they’re still spreading awareness because people don’t know fully comprehend climate change.

Teaching is fine, but if we're talking about direct effects then taking part in the climate strike is going to be drastically more impactful. It's almost certainly never going to happen on the scale necessary, but a national general strike is probably one of the few things that could actually make a difference.
