Checking our climate’s progress; 2024

Leave a comment

Now that warm weather has appeared in the northern hemisphere. It’s time to check on our climate’s progress. How well are we collectively doing to stop, or even diminish, global warming? I thought it might be useful to break the analysis into categories: data; government; business and the rest of us. Here are some, not necessarily comprehensive, results. As expected, they are mixed.

Data

Greenhouse gases

According to Co2.earth, the atmosphere’s level of carbon dioxide is currently (as of June 24, 2024) is 427.33 parts per million (ppm), a new record for the Human Era. In June 24, 2023 it was 423.35 ppm, an increase from June of 00.94%. This is a slight acceleration of the recent years’ trend. This equates to a global temperature change of +1.60C above the pre-industrial comparison period of 1880-1920. In short, no abatement is in sight.

Weather

The NOAA National Centers for Environmental Information (NCEI) has released the final update to its 2023 Billion-dollar disaster report, confirming a historic year in the number of costly disasters and extremes throughout much of the country. There were 28 weather and climate disasters in 2023, surpassing the previous record of 22 in 2020, tallying a price tag of at least $92.9 billion. This total annual cost may rise by several billion when we’ve fully accounted for the costs of the December 16-18 East Coast storm and flooding event that impacted states from Florida to Maine.

Don’t forget, this is just for the United States. Here’s a map for the world, courtesy of NOAA. The intensity of the red patches shows the above -normal temperatures. Seriously red patches tend to be heatwaves.

Remodeling central cities

Leave a comment

In January and June I wrote about the impending glut of office space in downtown areas. This is the result of the widespread adoption of telework starting with the Covid crisis. Now, more than three years later, it appears that the teleworkers remain resistant to full-time work in those central offices. Although the number of days they do come to the downtown office have increased, the average appears to be between two and three days per week. City centers clearly need remodeling.

So, the dilemma remains for the owners of all these office-dominant buildings. In many cases rental income is not just down, it’s seriously less than expenses. The problem has expanded to other areas as well. Businesses that depended on the daily influx of all those office workers now find that the flow has been cut at least in half. Once crowded sidewalks are now almost empty. Shops have been closed. Tax income has dropped for the cities. Crime rates in downtown areas have increased. The central cities as we knew them seem to have died.

But the buildings are still there. All that expensive real estate still exists. It would be foolish to just let it rot. So, what should we do to save the situation? Here are some ideas.

A gleam on the horizon for the climate

Leave a comment

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.

Energy tradeoffs in a distributed world

Leave a comment

When I started my research into telework my goal was to reduce the time and energy spent in the daily commute to work in a world where commute distances and times were steadily increasing. As global warming accelerates it is time to look at the bigger picture: energy tradeoffs in a distributed world.

At the heart of this concept are distributed networks as initially developed by the Advanced Research Projects Agency of the U.S. Department of Defense (now called DARPA). Their core idea was that, to avoid being shut down by attacks on key facilities, distribute and interconnect the facilities so that removal of one or more won’t affect the operation of the whole network. The system just works its way around the damage point. The Internet grew from that start.

Here’s a brief look at four types of network-related tradeoffs in the world’s growing dominance of electricity.

Near Future Estimates: Telework and Climate

Leave a comment

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

Leave a comment

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

Leave a comment

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.

Global warming: Checking the changes

Leave a comment

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

Leave a comment

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.

The climate countdown continues

Leave a comment

On 31 October 2021 COP26 begins in Glasgow. Hopefully, COP26 will act as an inflection point in the efforts to decrease global warming. With its success the climate countdown will continue. Hopefully, more nations will sign on and make quantitative commitments to end their emissions of greenhouse gases into the atmosphere.

Otherwise, greenhouse gases will continue to flow, the air will become warmer, destructive weather events will become more frequent and intense and humanity will increase fragmenting. All because Mother Nature will adapt to our mischief whether we like it or not. The earth will survive whether or not we do.

Here are some thoughts about the situation.
