Ok - carbon dioxide removal is going to be needed to meet to the 2 degree C target too.

Sure, you can reforest or afforest with whatever trees you want. It certainly will help but won't solve the issue alone.

According to the IPCC, to meet the 1.5 degree C target we need to be doing 6 GtCO2 of carbon dioxide removal per year by 2050.

It would be very difficult to reach that scale with reforestation and afforestation along in the next 27 years.

Plus, if you simply bury wood it will be broken down over time and release methane. No one has yet developed a scalable way to bury large quantities of wood and keep them from decomposing (startups/researchers are starting to work in this area).

One reason cooling is used is to protect the Li-ion or lead acid batteries in the uninterruptible power supplies that provide backup power to the servers. Both Li-ion and lead acid lose calendar life and reliability when operated at 40 C. So, you have extra battery replacement costs and reliability concerns at higher temperature.

I also would imagine that you need some type of cooling system even to keep the ambient temperature at 40C. Otherwise the servers are just continuously pumping out heat and the temperature may get high enough to the point where you have equipment issues. It could be the case that the equipment needed to cool to 25C is not that different or more expensive that the equipment needed to maintain a temperature of 40C.

A portion of parents are very worried about Covid in their children. These parents have sway with school administrators and local governments. All I am saying is that I doubt we get total easing of Covid restrictions until these kids have had ample chance to be vaccinated. I'm not making any arguments or claims about what you are taking about.

Yes - which why I doubt we will see full "reopening" everywhere until they open up boosters to everyone and provide time for people who want them to get them.

I could see things starting to really ease up once all children have had a chance to be vaccinated and everyone else has had a chance to get their 6 month booster shot.

1) A large increase in evictions will mostly affect the rental market. There would be some single family home rentals affected, but mostly it would affect apartments.

A lot of homeowners who needed help during the start of the pandemic were able to get a forbearance on their mortgage. Thus, there was not a huge increase in foreclosures and instead people just had extra payments tacked onto the end of their mortgage.

3) If anything, wealthy homeowners are getting a tax break. Congress is considering a repeal of the SALT deduction limit, which helps homeowners.

5) The number of people who were fired or quit due to mandates has been very small.

One group of people playing soccer, football, or baseball can take up almost the entire turf space in a small popular park. Think of Dolores Park is SF. On weekends it's packed with people picnicking. If instead 20 people were playing baseball, it would not be safe for anyone to picnic nearby because of the risk for errant baseballs.

On the other extreme end of things, one person hitting golf balls in a park can make the park unsafe for everyone else. At some point, the government institutes regulations to keep the park fun/safe/useful for the largest number of people.

It's similar in California. In the years leading up to the big Santa Cruz mountain fire in 2020, the scientists and forest rangers were aware of the increasing amount of fuel building up in the forest there. They simply weren't able to do the controlled burns they wanted because of a lack of weather windows for controlled burns. That area is also close to silicon valley so there are extra air quality requirements for the burns.

Much of the forest in CA is managed by the US Forest Service, so you can't blame CA officials for everything. Plus, you can only safely do controlled burns in certain weather windows (not super hot, rain likely coming, etc.). Given we are in the middle of a historic drought, the dry fuel levels are likely much too high to safely start controlled burns.

Yea, you are right about the 2% interest rates changing the breakdown. I was referencing numbers I ran back when rates were 3-4%. That said, most folks still rely on 30 years mortgages!

The first several years of the mortgage you are paying mostly interest and not as much towards equity. Plus, you have paid closing costs when you bought, will pay 6% to a realtor when you sell, and have paid property tax and homeowners insurance.

If you sell after 5 years, you are only making money if your home value happened to have gone up. This is by no means a guarantee on a short time frame.

Yep, that starter pack looks good. Love that they include a 6 speed driver instead of a 9 speed!

People who throw really hard probably benefit from the higher speed discs, but there are also very good players that drive 9 speeds. Advanced players will carry a variety of drivers with differing speeds because they will want different flight paths depending on the given hole layout. Also, whether you are throw into a headwind or with a tailwind changes how fast the disc is flying (relative to the air).

In general, most drivers are designed to fly in a "S" shaped flight path. When you get this full flight path, you get the most distance. For a right hand player throwing backhand that means your throw should draw slightly to the right at first, straighten out, and then finish with a fade to the left.

If you throw a disc that is rated at too high a speed for you, it will just quickly fade to the left and go into the ground. You often see beginners chucking their drivers way out to the right in order to compensate for this quick turn to the left. It's just really hard to get distance when you do this because the high speed disc really wants to turn left and dive into the ground.

If you throw a disc that is rated too low a speed for you, it will draw too far to the right and will not straighten out and come back left. In this case, you should either throw a bit less hard or move up to a higher speed disc. For beginners it is better to start here because you can actually get a feel for how throwing speed changes the disc flight path.
