You are very likely to come across the term 'greenhouse effect' when discussing climate change. Although the greenhouse effect is a natural mechanism that contributes to our planet with many advantages, there's another side of the story. Why is this phenomenon such a concern? What are greenhouse gases and what are their effects on Earth? In this article we will aim to answer these questions.
What Are Greenhouse Gases?
If the Earth had no atmosphere there would be radiative balance. In this case, the energy balance between solar irradiation (ultraviolet radiation or UV = extremely shortwave radiation) and terrestrial radiation (infrared radiation or IR = extremely longwave radiation) is equal. In this scenario, the Earth's surface temperature would be -18°C.
Fortunately, there is an atmosphere around the Earth where atmospheric gases are withheld. These atmospheric gases absorb and emit radiation and interact with solar and terrestrial radiation, increasing the surface temperature of our planet to an average of 15°C.
The Earth primarily consists of nitrogen (78%), oxygen (21%), argon (1%) and trace gases. The natural greenhouse effect is mainly caused by the following gases:
Ozone (near ground level)
These natural gases trap thermal energy in the atmosphere and make life on Earth possible. Also, clouds interact with the Earth’s radiation in the atmosphere. Clouds can heat and cool the atmosphere, depending on how much radiation they reflect back versus how much infrared radiation they keep back, just like greenhouse gases. The so-called anthropogenic or artificial greenhouse effect amplifies the natural greenhouse effect, leading to increased global temperatures by gases emitted from human activities (see the list of gases above).
The Greenhouse Effect and Climate Change
Greenhouse gases have far-ranging effects on the environment and health. They cause climate change by trapping heat and contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions and increased wildfires are other effects of climate change. Typical weather patterns are already changing. As a consequence, some species will disappear and others will migrate. Perhaps the biggest, most noticeable impact is glaciers, and ice caps melting faster than usual. The meltwater drains into the oceans, causing sea levels to rise.
Greenhouse gas emissions affect more than just temperature. Another impact involves changes in precipitation, such as rain and snow. Over the course of the 20th century, precipitation has increased in eastern parts of North and South America, northern Europe, and northern and central Asia. As climates change, so do the habitats for living things. Animals that are adapted to a specific environment may become threatened. Many human societies depend on predictable rain patterns in order to grow particular crops for food, clothing, and trade. If the climate of an area changes, the people who live there may no longer be able to grow the crops, they depend on for survival.
Considering the disruptive effects of greenhouse gases on our planet, it is no surprise that most climate scientists and experts are calling on individuals to reduce the number of greenhouse gases released into the atmosphere. Preserving the world we live in and pushing towards the next level is more possible than ever before. At Deutsche Aircraft, we are putting in our utmost effort, both as individuals and as an organisation, by investing in energy efficiency and sustainability. Join the march towards universal greenhouse gas emission reduction today!
About the data:
- Source: Cirium
- Schedules data: full year 2019 vs. 2020 – excludes non-scheduled flying
- In-service data:
- For 2019 the data is dated April while for 2020 it’s dated October. We wanted to compare “shoulder month” to shoulder month, however April 2020 wouldn’t have captured the immediate impact of Coronavirus as our dataset classes aircraft as in storage after 3 months of inactivity.
We are proud to present, “Aviation Ecosystem Review 2020.”
Based on market research surrounding our vision of building a sustainable future for aviation, this report provides insight into how we see Deutsche Aircraft fitting into the everchanging aviation environment.

As part of its continued support of Deutsche Aircraft’s D328eco aircraft programme, 328 Support Services GmbH recently appointed a panel of “talent experts” to further strengthen the overall team and ensure strong management structure and processes are in place across the D328eco development programme. Today we focus on the Engineering & Programme departments.
On the programme side, Mr. Peter Spyrka has been appointed Director of Programmes. Peter brings over 20 years’ experience in the global aerospace industry with engineering & development works on both civil and military aircraft programmes. Prior to joining Deutsche Aircraft, Peter worked at Airbus, leading the Hybrid Electric Propulsion System development programme for demonstrator projects. He also worked for Fairchild Dornier back in the late 1990’s.
In Engineering, Mr. Jean-Damien Mazeau has been appointed as our new Head of Propulsion Systems. Jean-Damien also brings more than 20 years’ aeronautical experience to Deutsche Aircraft, having built most of his career at Airbus. He was most recently involved with the A320neo’s entry into service, in charge of propulsion system’s global technical Support.
Last but not least, Dr. Stefan Brunner brings more than two decades of expertise and experience to his position as Head of Airframe. Throughout his career, Stefan spent more than 17 years working directly for the Airbus group where he was heavily involved with a wide variety of major engineering programmes on both commercial aviation and defence & space programmes. In his new role, Stefan will be responsible for design, analysis and modification of the D328eco airframe’s primary structure (Fuselage, Fairings, Wing, Empennage), as well as establishing new processes and procedures to complete aircraft development. Finally, he is responsible for ensuring compliance with the European Authorisation and Restriction of Chemicals (REACH) regulations.
In addition to Peter, Jean Damien and Stefan, we are also proud to announce that we have been busy hiring new talent from not only within Germany, but from all over the world. Coming from a variety of companies within the aerospace industry, we look forward to utilising our new team members’ skills and expertise to achieve the entry into service scheduled for 2025.
All are great assets to the current Engineering & Programme team and will, without a doubt, help support Deutsche Aircraft’s development programme over the coming years.
