Spring has gone on spring break this week, so while I find the weather pleasant and enjoyable, it still feels like mid-March. That makes it more palatable to remain indoors for lunch and catch up on these stories:
And finally, via Bruce Schneier, Australia has proposed starting cyber-security training in Kindergartens.
The decennial update of the 30-year US climate normals dropped this afternoon. They show the US has gotten measurably warmer over the 1981-2010 normals:
NOAA’s new U.S. Climate Normals give the public, weather forecasters, and businesses a standard way to compare today’s conditions to 30-year averages. Temperature and precipitation averages and statistics are calculated every decade so we can put today’s weather into proper context and make better climate-related decisions.
Normals are not merely averages of raw data. Thirty years of U.S. weather station observations are compiled, checked for quality, compared to surrounding stations, filled in for missing periods, and used to calculate not only averages, but many other measures. These then provide a basis for comparisons of temperature, precipitation, and other variables to today’s observations.
As anticipated, changes have occurred in averages since the last ten-year update.
For instance, the north-central U.S. Temperature Normals—for those in the Northern Plains and Upper Midwest—have cooled from 1981–2010 to 1991–2020, especially in the spring. The South and Southwest are considerably warmer. Normals were also generally warmer across the West and along the East Coast.Precipitation-wise, the Southwest was drier; wetter averages emerged in the U.S. east of the Rocky Mountains, especially the Southeast in the spring.
[L]ong-term trends from decade to decade can affect baseline “normal” weather conditions. For instance, the last decade includes the warmest seven years on record for the globe, according to NCEI.
Chicago got just a little warmer and just a little wetter, as anticipated. Southwest Texas got much warmer and dryer. And Florida is still part of the US. Two of these things are suboptimal.
And if you aren't sure climate change is happening, check this out:
We have gloomy, misty weather today, keeping us mostly inside. Cassie has let me know how bored she is, so in the next few minutes we'll brave the spitting fog and see if anyone else has made it to the dog park.
All right, off to the damp dog park.
The wind shifted abruptly just before 6pm last night by my house, bringing with it a remarkable drop in temperatures. I live about 1½ km from Lake Michigan, which (with Lake Huron, hydrologically the same body of water) is the second-largest fresh-water lake in the world. In the summer, it keeps Chicago cool. In the winter, it keeps Chicago warm. In the spring, it keeps Chicago paying attention to the weather forecast.
Exhibit 1, temperatures near O'Hare at 6pm yesterday. Note the 13.3°C gap between Chicago and Wheeling, which are just 13 km apart:
Exhibit 2, when the cold front finally reached O'Hare around 8pm:
One tends to notice when the temperature drops 15.6°C (that's 28°F for you philistines out there) in less than an hour.
In other news, after tying a record high temperature yesterday (30.6°C, tied with 1986), today my home office is actually quite comfortable.
Sunday evening we had 4°C gloominess with gusty winds. Today we've got 28°C sunniness with gusty winds. We've also got a bunch of news stories to glance through while a build completes:
Cassie has plotzed on the sofa, probably from the heat and from spending all day yesterday at doggy day care.
And here's the CDC's latest chart:
Happy 51st Earth Day! In honor of that, today's first story has nothing to do with Earth:
Finally, it looks like I'll have some really cool news to share about my own software in just a couple of weeks. Stay tuned!
Some stories in the news this week:
Finally, the House Oversight and Reform Committee advanced DC statehood legislation. The full house may even pass the DC Admission Act next week.
Bit of a frustrating day, today. I spent 2½ hours trying to deploy an Azure function using the Az package in PowerShell, before giving up and going back to the AzureCLI. All of this to confirm a massive performance issue that I suspected but needed to see in a setting that eliminated network throughput as a possible factor. Yep: running everything completely within Azure sped it up by 11%, meaning an architecture choice I made a long time ago is definitely the problem. I factored the code well enough that I can replace the offending structure with a faster one in a couple of hours, but it's a springtime Sunday, so I don't really feel totally motivated right now to do so.
Lest you worry I have neglected other responsibilities, Cassie already got over an hour of walks and dog park time today, bringing her up to 10½ hours for the week. I plan to take her on another 45-minute walk in an hour or so. Last week she got almost 14 hours of walks, however. I blame the mid-week rain we got.
I also have a 30-minute task that will involve 15 minutes of setup, 10 minutes of tear-down, and 5 minutes of video recording. I will be so relieved next fall when all of our chorus work happens in person again.
Before I do that, however, I'm going to go hug my dog.
I've been coding most of the day because it has rained since 1pm. I'm getting very close to a series of posts on what I've been working on the past few months, so stay tuned.
It's the warmest day of 2021 so far, up to 21°C at Inner Drive Technology World Headquarters, so basically I'm just in between Cassie walks. (She's gotten two hours already today, including half an hour at the dog park.) Tomorrow it may be cooler, but still 16°C by mid-afternoon.
So, posting may be light this weekend.
