Re: UAH version 6 now out

Presumably if one removed all the wiggles then the p-value would be 0.000 and the trend would remain the same.

If you believe that then the p-value is irrelevant. The point of the p-value is it tells you the likelihood that you would [more]

Re: UAH version 6 now out

The p-value for the slope tests the null hypothesis that the slope is equal to zero. A low p-value (< 0.05) indicates that you can reject the null hypothesis

Nobel Laureates by school:

Interesting list. While Nobel Laureates typically do their prize winning work when they are relatively young, probably around 30, the prize is often not awarded until decades later. The Nobel Prize is a [more]

Re: odd Apple Mail problem

I suppose I could just buy iPads for everyone.

like (presumably) most families, the "main" computer has all our email accounts on one user

Re: Roof Replacement

And we expect to sell this place in less than a year, so the timing for us was lovely. New roof for $500, just in time to put it on the market.

We had a hail storm a few months before we put our home on the market and and didn't [more]

Re: taxaudit.com not reliable (Long)

One potential increase is some sort of change to Roth accounts that would tax some portion of the earnings in those accounts.

I think the most likely first step would be to implement a mandatory withdrawal from Roths at age 70 1/2. [more]

Re: Wealth, Energy, and Work

What makes energy so useful in physics is that it is conserved. Solar energy can be transformed to chemical energy to electrical energy to kinetic energy and ultimately to heat. Because energy is neither created or destroyed you can track it from [more]

climate impacts of low sensitivity

In reading about the latest Stevens paper and ideas about the Iris effect I came across some comments that raised an interesting issue.

We know CO2 causes warming, and we know water vapor feedback is positive. So if the climate system truly [more]

Re: Energy = Wealth

I agree that we will see significant improvements in clean energy generation and storage, but you have to replace 200+ million years of natural carbon energy storage.

The amount of solar energy the Earth receives dwarfs our current [more]

Re: Reanalysis

What is reanalysis in the climate world? Basically, it is running a model which is constrained by real-world observations.

A new spark plug does wonders.

Went to Home Depot to get oil and an air filter for my 10 year old Toro. I was pleased to find that a tune-up kit that includes a spark plug cost less than buying the oil and filter separately. The new [more]

One factor is that I look at the statistics a lot while I run.
