Telework and Heat: Some Energy Tradeoffs

The world increasingly melts in summer heat. The impending future shows more of the same. Every year there will be even more heat than the year before. All of this is because of climate change which, in turn, is mostly the result of our continuous burning of fossil fuels. A substantial fraction of that heat input still comes from traffic involving internal-combustion-(IC)-propelled cars. There are at least two ways of attacking this problem. One is by reducing or eliminating car use by telecommuting. Fifty years ago, we reported the results on our test of telework, entitled The Telecommunications-Transportation Tradeoff[1]. It was successful in reducing car use.

Another approach to the heat problem is by replacing IC cars with electric vehicles, EVs. In the 2020s EVs started to appear in substantial quantities.  Now let’s review the energy tradeoffs in terms of heat balances between these two options.

COP28: The prelude

COP28, the 28th Conference Of the Parties has begun this week with representatives from 200 countries. The main theme of the conference is fast tracking the transition to zero net emissions of greenhouse gases and, specifically, to get half the way to zero by 2030. Further, the goal is to limit global warming to 1.5C (2.7F) above pre-industrial levels. What are the chances of success?

First, note that the world exceeded 1.5C for a day or more just recently. Global average temperature continues to increase monthly. Most of the increase is due to China, the United States, the European Union and India. Most of the ill effects of that increase fall on other countries, particularly those that have low emissions. So what should happen during COP28?

A gleam on the horizon for the climate

Most of my writing on climate change has shown some level of despondence. So far. But now I’m beginning to see a gleam on the horizon. Despite what has happened this summer. The ungainly ships of state are beginning to turn around. Here are some examples.

The United Kingdom

The UK’s Prime Minister, Rishi Sunak has been walking back some of his government’s promises on climate. For example, he has been pushing back several green targets from 2030 to 2035, including a ban on the sale of new petrol and diesel cars; relaxing the phaseout of new gas boilers; and cessation of drilling for oil in the North Sea. His reason is that he doesn’t want to unduly burden citizens with the costs associated with these changes.

Coping with Climate stress

Reports of growing climate disasters keep arriving. If you continue to read them the result may be an increase in your stress levels. Here are some comments from Lucy Reed of GigMine on possible options for de-stressing while also doing something positive to change the future.

Five Ways to Cope with Climate Anxiety While Making a Difference

Paying attention to climate issues can be stressful, especially when spending hours per week trying to stay informed. Sometimes, it can be easier to check out and not pay attention to prevent an overload of anxiety. Statistics show that 60% of young people feel worried about the environment. Thankfully, there are ways to make an impact while taking care of your mental and physical health. Today, JALA International shares five ways to cope with climate anxiety while making a difference.

Near Future Estimates: Telework and Climate

Now that we’ve arrived at a new year it’s time to consider what might be coming up with respect to telework and climate change. The short answer is that the future of telework looks rosy while the future of the climate continues to be grim. Further, although telework is looking good some of its disruptive side effects are definitely appearing. While global warming continues pretty much unabated, reductions in the rate of increase appear on the horizon.

Here are some details.

Telework

A major side effect of the Covid pandemic was the almost instant rush of office workers from downtowns to home offices. Now that Covid is essentially over in the United States and Europe, if not in China, many tradition-minded executives demanded that their employees return full-time to their central urban offices. That usually didn’t work. Those millions of workers who have experienced working from home for more than two years are resisting going back to the old ways full time.

COP27: A little bit of this, none of that

The 27th United Nations Conference of Parties has limped to a close with results that are disappointing at best. The delegates did agree to provide some forms of help to the countries most affected by climate change but nothing about the gorilla in the room: climate change itself. It was little bit of this (help), but none of that (serious change in emissions). So another year has passed without a serious international effort to reduce the emissions of greenhouse gases, the sources of climate change.

Here are some details plus a bit on the other Conference of Parties, COP15.

The climate countdown: 2022 edition

This year’s international conference on the climate, COP27, begins on Sunday, November 6th at Sharm el-Sheikh, Egypt. The previous conference, COP26, resulted in a number of promises to reduce the production of greenhouse gases (GHGs) with the objective of limiting global warming to 1.5C above pre-industrial levels. COP27’s goal is to see how well the world has been doing so far and to plan what must happen next.

The key issues are: is global warming better or worse than it was in COP26; how fast is global warming changing and in what direction; how close are the facts to what was promised last year and what must be done to reach the 1.5C goal?

It’s time to check the evidence so far and think about alternative futures.

Telework in Summertime

Summertime is here. In many places it’s here with a vengeance. Heat waves are roasting Europe and North America. It’s clearly time to consider telework in summertime. Here are some comments.

Britain breaks heat records

In mid-July British authorities published “red” heat warnings for the first time ever. An overheated Summertime. Temperatures reached 100F in London, the Midlands, the south of the UK and Wales. Records were broken in several cities.

Now, for Texans, this doesn’t sound too unusual but consider the infrastructure in the UK. Houses and offices are built to retain heat not get rid of it. Ditto for subways. Neither are adapted to hot summers. Consequently the traditional commute to/from work is enervating as is much time spent in an non-airconditioned office.

Global warming: Checking the changes

Now that Summer has arrived in the Northern hemisphere it’s time to check the changes in global warming since COP26. It seems that the answer is: very little change, most of it negative. The promises I wrote about in April last year are still mostly promises. The level of CO2 in the atmosphere continues to steadily rise. One new factor has altered the future for the worse: the war in Ukraine.

What follows is a sorry summary of recent events, their consequences and some opportunities.

Steps to combatting global warming: Methane

Although much of the focus in talks about global warming is on carbon dioxide (CO2), methane (CH4) may be even more important in the near term. The reason methane is important is because it is much more effective than CO2 at increasing warming. Even though it doesn’t last as long in the atmosphere. So while atmospheric CO2 may be around for hundreds of years, methane is a powerful factor now. Here are some facts and suggested steps to combating global warming by reducing methane production.
