Earth Overshoot Day

Globalisation and the industrial revolution have brought many positive changes for people. Still, dramatic consequences for our planet. Our environment and many ecosystems are heavily polluted by all kinds of contaminants. People are destroying the earth more and more every day, not thinking at all that this is our only earth.

Saving energy while protecting the climate?

The times when climate and environmental protection were always clearly on the “good” side are over. In the real-life implementation, alternative energies collide with nature conservation and species protection, as, e.g. in the case of off-shore wind farms. The discussion about “clean” nuclear energy is also difficult. In general, this means that one must take a closer look, weigh up the (long-term) impacts and evaluate the planned measures accordingly in a comprehensive manner. 

There are also side aspects to consider regarding air quality measurement. It is almost a paradox when air quality is measured by driving vehicles through the city. If the car has an electric drive, this has, at best, a NO2-reducing effect. The fine dust pollution from brake and tyre abrasion remains. And the environmental problems associated with the production of the necessary car batteries are widely known. 

A very topical issue at the moment is energy supply and energy consumption. There are also substantial differences in energy consumption of air quality measurements. The containers that operate the public measurements have an annual energy demand of 3,500 kWh to more than 11,000 kWh, depending on the equipment. This means that even the more economical measuring stations consume more than a typical 2-person household.  

With the Hawa Dawa measuring devices, the energy-consuming conditioning of the air before measuring is taken over by a calibration algorithm through the innovative use of artificial intelligence. This means that the annual energy consumption of our measuring devices is at the level of a standard household freezer – i.e. a fraction of the energy that has to be provided for a measuring station. 

Climate Justice – a topic no longer to be ignored

One of the most urgent aspects of climate action is environmental justice. At the ChangeNOW event in Paris, an entire session was dedicated to the fact that the people, who have the least impact on climate change, are the ones who are impacted the most – as the moderator, Lovelda Vincenzi, put it. The panel‘s discussion was around that the climate urgency is a global crisis, but its effects are not felt evenly around the world. The least polluting populations are the worst affected by climate change. International changemakers and political leaders must protect the rights of the most vulnerable and ensure the burdens of climate change are shared equally and fairly.

Tipping Points in Detail | Melting Ice (Ep 3/3)

We see pictures of emaciated polar bears every day and pity their fate – they are a living example of the sad reality in the Arctic. Yes, we pity them, but we often don’t realise that the melting of Arctic ice is just as damaging to us as it is to them.

Tipping Points in Detail | Ocean Currents (Ep 2/3)

Nature can be imagined like a human body. It is an arbitrarily complex system – everything is interconnected and in constant exchange. If one variable gets out of balance, the whole system can collapse. This is also the case with our oceans, the largest ecosystem covering over 70% of our planet.

Tipping Points in Detail | Amazon Rainforest (Ep 1/3)

We have already reported on tipping points and their properties in a previous blog post. What they are and what significance they already have for our environment. Since we would like to report in more detail about tipping points, we are dedicating a separate series to this topic – “Tipping Points in Detail”. In the first blog post of the 3-part series, we would like to bring you a little closer to the topic of the Amazon Rainforest. In the second part, we will talk about ocean currents and their importance for the animal and plant world and the effects on us humans. In the third and last part of our series, we will highlight the ice melt at the polar ice caps and some local glaciers.

Earth Day 2022 – get active now!

This year’s „Earth Day“, officially named „Mother Earth Day“, is the first one celebrated within the UN Decade on Ecosystem Restoration. Ecosystems support all life on Earth. The healthier our ecosystems are, the healthier the planet – and its people. Restoring our damaged ecosystems will help end poverty, combat climate change and prevent mass extinction. But we will only succeed if everyone plays a part.

We will share a couple of initiatives that try to activate all of us by using new approaches. Read more

Earth Day 2022 – A day for our Earth

For 52 years, Earth Day has been celebrated on 22 April in over 190 countries. The aim of the day is to raise people’s awareness of the importance of the Earth and the ecosystem and the consequences of environmental degradation in all its facets. People should rethink their own behaviour and question their everyday conduct.

Why ground-level ozone air pollution is a risk to food security

According to an IPCC scenario, the concentration of ground-level or tropospheric ozone (O3) may reach 70 ppb in 2050. Then, more than 30% of global cereal acreage could be exposed to significant ozone pollution, which in turn would lead to significantly lower crop yields.

Ground-level or tropospheric ozone (O3) is ingested by plants through their stomata (pores in the epidermis of plants) and has a growth-inhibiting effect: O3 leads to a reduced rate of photosynthesis, increased respiration and accelerated ageing of leaves. O3 also increases the plants’ susceptibility to diseases and other stress factors. O3 is also thought to alter the concentration of nitrogen, carbohydrates and phenols in the leaf and grain.

Bees: The impact of climate change and their importance for humans

Once the bee disappears from the earth, humans have only four years to live. No more bees, no more pollination, no more plants, no more animals, no more people.” (Albert Einstein, 1949)
