Supreme Court: Are You Tired Of Winning...

[RumTumTugger]

Hehe, but I think the Remain policy was an executive order - correct?

i'd have to look it up but I think this was a law enacted by congress when the republicans were in control that Trump signed into law and then enforced it.

Given that carbon monoxide indirectly contributes to the build-up of some greenhouse gases, the following is from a serious article on why even temporarily going beyond a 2^oC rise could cause permanent damage to the species on this planet, including of course, our own.

Positive climate feedback

Figure 1. A map showing the decrease in arctic sea ice over the years. The melting of ice and corresponding change in albedo is one major positive feedback.^[1]

Positive climate feedback is a process that is one type of climate feedback wherein some initial change in the climate causes some secondary change that in turn increases the effects of the initial change, essentially magnifying the initial effect.^[2] Positive climate feedbacks are often discussed in the context of climate change and is one sub-type of positive feedback.

Similar to how keeping money in a savings account earns interest and compounds to earn more money, positive climate feedback increases some initial change in the climate. Some initial warming is accompanied by additional warming from some other process, which in turn results in even more warming. For further explanation on what a positive feedback is in general, click here.

Although there are also negative climate feedbacks, positive feedback cycles are what are so disconcerting. Positive feedback cycles accelerate climate change as they increase warming, leading to large non-linear responses. With positive feedback, some minor change in the state of the climate can result in a large change overall. This is in stark contrast with negative feedback, which reduces the impact of some initial climate change by acting in the opposite direction, bringing it back to its initial state.^[3]

Examples of Positive Feedback
There are disconcerting positive feedback cycles being observed and predicted.^[4] It is important to note that these different types of positive feedback result in a different amount of warming overall. The following are a few of the climate endangering cycles.

Ice-Albedo Feedback
One example of a positive feedback is the melting of ice - particularly sea ice - and corresponding decrease in albedo (see Figure 1). Ice is white and highly reflective - corresponding to a high albedo. This reflectivity prevents some incident sunlight from being absorbed.^[2] However, when ice melts the vegetation, soil, or water beneath it is exposed. These surfaces are darker and heat faster and thus have a lower albedo. As these surfaces with a lower albedo are exposed to the Sun, they absorb more solar radiation than the ice would have. This absorption further raises temperatures and causes even more ice to melt, continuously heating and pushing the cycle. This feedback can act more quickly over the ocean than over land as sea ice is able to melt more quickly than large, continental ice sheets.^[4]

Water Vapour Release
The human-caused release of greenhouse gases into the atmosphere as a result of fossil fuel combustion is the initial cause of climate change. These human activities increase global temperature as these gases trap heat in the atmosphere as a result of their basic properties. The feedback comes when the warmer atmosphere results in more evaporation of water on the surface of the Earth. As the water from the Earth evaporates, it turns into water vapour in the atmosphere. This water vapour thus causes even more warming of the atmosphere, creating a self-reinforcing cycle of heating.^[4]

Carbon Release
As the temperature on the Earth increases, permafrost begins to thaw. This permafrost contains large amounts of carbon that was contained in frozen soil. Thus the melting of the permafrost releases methane into the atmosphere. As these greenhouse gases are released they cause more warming, which in turn causes more thawing and more carbon release.^[4]

I think she's off on a tangent that we really shouldn't be against abortion because all those babies are going to be subject to the horrors of climate change.

Remember, this is H_A we're talking about.

What the EPA was doing was unlawful. They had no such right. Such policies must be passed through the Congress.

[Hypatia_Alexandria]

What the EPA was doing was unlawful. They had no such right. Such policies must be passed through the Congress.

As I understand it this ruling will begin to remove the powers of agencies such as the EPA to enforce policy. Rather than allowing federal agencies to enforce such things as the Clean Air Act, this new dispensation will require Congress to pass much more explicit regulations. However, this ruling will no doubt render it nigh on impossible to get any clear statements from Congress. When was the last serious climate bill passed by Congress?

Furthermore, this recent ruling will make it even harder to achieve any international progress on rising temperatures. If the US [historically the world's largest emitter of carbon] cannot play a serious policy role it will be increasingly hard for the US to play a serious international leadership role.

With unprecedented flooding in Asia and heat levels in the Middle East; a prolonged drought and then record fires in the US south west as well as the recent extensive rainfall and flooding in Yellowstone, where is all this going to end with a climate that is out of control?

Cow Poke joked about "doomation" but what does all this promise for his, or indeed anyone else's great grandchildren when they reach their sixties or seventies in another one hundred years or so?

No the EPA was going beyond their mandate. And yes, the Congress has to get more explicit. That is how US law works. Whether Congress acts or not has no bearing on the EPA overreach.

The US economy has grown over the last 30 years yet our CO2 footprint has actually gone down.

Who knows, without China, India and Africa getting on board (and they aren't) what we in the West do won't help much. And isn't your country turning more and more back to fossil fuels like natural gas?

then record fires in the US south west

I'm sorry but there are not 'record fires in the US south west'.

Indeed, they are miniscule compared to the fires that occurred in the 1500s-1800s. We used to have 100s of millions of acres burning ANNUALLY, average of around 150 million per year. For comparison, our 'record fires' this year amount to a measley 3 million (1.5 million last year) acres burned thus far.

And most of the fire issues we have today are due to 'environmentalists' interfering with forest management and the long-time policy of suppression of all fires no matter if they threaten anyone or not, and even then we are not even close to those record fires before 1800s

That this ruling is going to assist in exacerbating climate change.

Which is not relevant because it is not the sort of thing the Court is supposed to consider (at least from the perspective of judicial conservatism). Outcomes and their potential impacts should rank far below the question of whether the law or regulation being disputed is in keeping with the Constitution, if those outcomes and potential impacts are considered at all.
