technology for a better life

Well, hello to all technology people; I have had the opportunity to contact a professor who is personally known to Professor and to talk and get in touch with a new project on technology and 2B Technology and Professor. Wishing that this article was added to my column, it was a pleasure and a long time friendship and personal friendship that I had heard of research on the technology life of A long time professor who was unsuccessful at the time and is now thriving, I would like to present his work and provide details of his career to my website for publicity and for I’m waiting for a letter from the professor to confirm that all the documents and detailed information available on this website are real and not copied from and that he is willing to give me for publication. With the public benefit, I ask everyone to wait a little longer and see you soon.

Today website techbforbetterlife.com welcomes  2B Technology

2B Tech Co-Founder John Birks Honored with the
2022 Future of Life Award

2B Tech Co-Founder John Birks Honored with the

 We are incredibly proud to announce that John Birks, Co-founder of 2B Technologies, has received an award from the Future of Life Institute for his role in discovering and communicating the climatic effects of nuclear war, i.e., “nuclear winter.”

John’s paper, co-authored with Paul Crutzen and published in 1982 in Ambio, was the first to show how widespread fires from nuclear weapons would generate enough smoke to significantly block sunlight for many weeks, triggering worldwide famine through its effects on agriculture. “The Atmosphere After a Nuclear War: Twilight at Noon” was a catalyst for international research on the topic, leading to the popularized term “nuclear
winter.”

World leaders in the late 1980s, notably Ronald Reagan and Mikhail Gorbachev, understood that even a limited-scale nuclear war would devastate the entire planet. This work is widely credited for ending the nuclear arms race, and many believe it helped prevent a nuclear war between the Soviet Union and the United States.

Watch the video below about how John and his colleagues’ science entirely averted disaster and protected humanity.

Wildfire Plumes Are Getting Taller–And Why That Matters, New Findings Have Implications for Air Quality, Climate

re frequently. They're getting more


Wildfires are not just occurring more frequently. They’re getting more intense…and according to a new study, they’re getting taller.

That matters because the plumes are like a pipeline for transporting particles to the upper layers of the troposphere and even the stratosphere, where they can then spread farther. This means that the effects on air quality have become more extensive. For example, Utah is more likely to experience the impact of fires than California. Indeed the results can become continental in scale. In August 2018, Western Canadian wildfire smoke reached New York City.

In the new study, researchers from the University of Utah  focused on the American West and
Canada, assembling a database of an astounding number of plumes (~4.6 million) that occurred in August and September over the years 2003-2020. Modeling the plume data, they determined the trends in the maximum height reached by the plumes. In nearly all areas, the full size increased from 300 to over 700 feet per year. (To put it in perspective: The Eiffel tower is about 1000 feet tall.)

The biggest jumps in max plume height also seemed to occur in recent years, suggesting that the trend may accelerate. More data are needed to establish this impression statistically.

When fire plumes reach further upward,  there are consequences for climate as well as air quality. In the higher layers of the atmosphere, the particles have a longer lifetime and exert direct and indirect radiative effects. And there is the risk of a potential feedback loop in which the lofted particles suppress rainfall, increasing wildfire activity.

The authors note that the trends in wildfires and their plumes are most likely due to climate changes, such as increasing temperatures and decreasing precipitation. Though many nations are taking various actions to address climate change, lead author Taylor Wilmot notes that to some extent, the horse is already out of the barn: “The reality is that some of these [climate change] impacts are already baked in, even if we cut emissions right now. It seems we’re largely along for the ride at the moment.”

Case Study: 2B Tech’s Model 106-L Ozone Monitor

Monitoring Ozone in the Remote Forests– for Years!

Using 2B Tech’s Monitors Found to be Cost-Effective and Sustainable

How does ozone pollution affect forests? And what happens if you put our 2B Tech ozone
monitors in the remote forest for FIVE YEARS to find out?

Using 2B Tech's Monitors Found to be Cost-Effective and Sustainable

Researchers in Europe did that, leaving our Model 106-L monitors (in our rugged “Industrial” enclosures) in remote forest areas to run unattended for long periods. The study looked at costs compared to a passive ozone sampling system that was less expensive at a startup.

Modeled monetary costs of passive sensor systems (IVL, OG)

Over the long haul, it was more economical and environmentally sustainable to run the 2B Tech systems because they required less frequent human interactions and fewer trips to the monitoring sites. In addition, the higher quality of the 2B Tech monitor data meant that researchers could use the data in stomatal flux studies of how the ozone affects the trees. This is a “WIN x 3” for the researchers, the trees, and 2B Tech! Read the open-access study by Carrari et al., linked below!
