Have you noticed Climate Change?

I have this simple question. Have you noticed Climate Change?

I believe the summer heat has helped many in the northern hemisphere to notice that something is going on. However, climate change is not only extreme heat but a lot more.

Lots of news are covering the record temperatures that are registered in places never seen before. Lots of articles are talking about the deaths these high temperatures cause. All of them are true, but no one mentions the effects on the environment that supports our food chain and the animals that live on this planet too. Crops and animals, suffer a lot, and they don’t have an air conditioner to cope with the heat or an air purifier to cope with the air pollution.

Ozone (O3)

Ground-level ozone causes more damage to plants and trees than any other air pollutant. Ozone penetrates leaves through stomata (tiny openings present on the epidermis of leaves) during gas exchange. Ozone is a strong oxidant, and it causes several types of symptoms, including chlorosis (yellowing of leaf) and necrosis (the death of the tissue).

CO2 Trio Side by Side: Single Beam NDIR vs Dual Beam NDIR vs Photoacoustic

Sotirios PapathanasiouLeave a comment

So many different types of sensors have become available in the market. For years we have seen and used Single (mainly) and Dual-Beam NDIR sensors for CO2 detection, but now another technology has surfaced, the Photoacoustic.

I decided to do a quick comparison of the different technologies in order to determine which one is the best and what are the differences if there is one. Price always affects the Bill of Material BOM, so we need to make a wise choice depending on the application of the sensor (commercial, real estate, industrial, scientific, etc).

Single and Dual Beam NDIR

CO2 is a gas with an asymmetric molecular structure that has strong absorption of infrared. This is the reason we use a Non-Dispersive Infrared NDIR sensor which is based on tunable diode laser spectroscopy.

What Is COP26 & What Does It Mean For Our Climate?

Sotirios PapathanasiouLeave a comment

COP26 stands for Conference of the Parties, which are the countries that signed the United Nations Framework Convention on Climate Change (UNFCCC). The 2021 meeting will be the 26th meeting. Initially, it was due to take place in Glasgow in Scotland in November 2020, but it was postponed for a year because of the COVID19 pandemic.

During COP26 governments will demonstrate their commitment by showing how they will keep global temperature rises below 1.5ºC, deliver money promised to countries on the front-lines of the climate crisis, and shift away from fossil fuels.

So far and after the Paris Agreement little has been done in order to reduce greenhouse emissions. The pressure governments receive is even greater than before because the climate crisis is already unfolding in front of your eyes as more and more people demand actions.

Global Warming

Many people with a lack of understanding for the term global warming just believe that some seasons will be warmer, so what! The term global warming has indeed misled the population for many years as it doesn’t describe the real scenarios of the alteration of the climate on a global scale. Today, there are many terms available trying to describe and help people understand better the severeness of the issue.
