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.

European Environment Agency presents the report on the state of air quality

In its report published in April, the European Environment Agency (EEA) presents air pollution levels by pollutant in 2020 and 2021. Pollutant concentrations are presented in relation to EU air quality standards and WHO guidelines. The World Health Organisation (WHO) has already adjusted its recommendations significantly downwards in autumn 2021, considering the latest research findings on air pollution-related health risks.

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.

Sahara dust in Europe: a natural spectacle with health implications

When Sahara sand is blown toward us, we initially perceive it as an interesting visual spectacle: the sky turns yellowish, and the atmosphere outside is reminiscent of warm Christmas lights. As soon as the sand settles as a fine layer of dust on cars, garden furniture and window sills, we are usually less enthusiastic… Read more

Skin and air pollutants – does city air make us look old?

Air pollution is a great enemy of our health! But not only for eyes, lungs and heart, but also for our skin. The skin is the largest human organ in weight and surface area. The skin is like a protective coat and fends off environmentally harmful influences such as particulate matter, soot and smoke. However, this constant work that our skin does can also leave its mark. If the skin is exposed to continuous air pollution, skin problems and diseases result.

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)
