Veganism – solving the climate issue?

by Ella Karnik Hinks

Germany’s Federal Statistics Office (Destatis) just released a report showing that in 2020 the amount of meat produced in the country dropped by four percent. Conversely, production of meat substitutes rose by 39% [1]. With record numbers signing up to Veganuary this year, the controversy around veganism seems to be diminishing. The question is, is going vegan really good for the climate?

500,000 people participated in the global campaign Veganuary which encourages people to commit to a month of veganism in January [2]. The number of vegans in Britain has quadrupled in 5 years to 600,000 according to the vegan society, whereas in Germany the figure has reached over 2 million. Far from being the fringe lifestyle choice of a few hippies, more and more people are turning to veganism for a wide range of reasons related to health, morality, or climate protection.

Why climate and environment belong together

by Felix Schaumann

In a recent blogpost, I argued that climate policy should be seen and treated as something fundamentally different from environmental policy. However, I am not sure I entirely convinced even myself. Therefore, I’d like to use this piece to take the opposite stance, by arguing that climate and environmental problems should be confronted together.

It is true that the main cause of climate change consists of burning fossil fuels, suggesting a focus on economic solutions relating to energy use. However, it is also true that the effects of climate change present themselves as environmental problems – ranging from storms and droughts to the extinction of species and the loss of entire ecosystems.

2020 on Twitter – Was there a topic besides Covid19?

by Fenja De Silva-Schmidt

After the outstanding year 2019, attention for climate change on Twitter in the past year quickly dropped to the level from the years 2018 and before. The harsh decline directly coincides with the rising worldwide attention for the “new” Corona virus later named Covid19, which caused the global pandemic the world is still struggling with. This looks like a prime example for the “Crowding-Out Effect”: Environmental topics tend to be pushed out of media reporting and public attention in times of crisis (Djerf-Pierre 2012).

Nevertheless, climate change punctually received high attention on Twitter. In the first months of 2020, the topic was still as high on the agenda as in the end of 2019, with natural and political events triggering peaks of attention.

*The Online Media Monitor on Climate Change Coverage (short form: OMM) collects tweets related to climate change if they contain at least one of the search strings #climatechange OR “climate change” OR “global warming” OR Klimawandel and receives at least 5 retweets. Read the OMM Guide to get more details about the methods and take a look at the error log file to get information about server problems.

Why Climate Policy is not the same as Environmental Policy

by Felix Schaumann

Climate change is receiving more and more attention. While the topic has traditionally been seen as an environmental issue, it is now increasingly reaching beyond and detaching from the sphere of classical environmental policy. In this piece, I will argue that this is a good thing.

The environmental movement has been around for half a century now, at least in many parts of the world. While it has had many successes, it is still a minority in society. At the same time, ambitious climate action is required to happen within this decade, if we want to fulfil the Paris Agreement. In order to instigate political action now, it is necessary to build coalitions that amount to societal majorities, thereby reaching far beyond environmentalist circles.

Planting trees to save the climate?

by Susan Jörges

„We plant one tree per product”, an organic chocolate bite company claims that cooperates with Eden Reforestation Projects. “With your help we have already planted 15.000 trees in Columbia”, is written on the website of a company that sells organic cosmetic products in recyclable glass bottles. Planting trees for every product sold seems to be fashionable. Product variety is expanding on all markets, and consumers are becoming more critical.  But is planting trees an effective solution for preventing climate change? Is climate change mitigation that easy?

2019 on Twitter: Climate activism awakening

by Hadas Emma Kedar and Fenja De Silva-Schmidt

Shortly before 2020 is over, we will have a look back at 2019 to map the climate change debate as reflected transnationally on Twitter. Compared with the two years prior, 2019 showed a particular abundance of climate-related tweets: While the total tweets count of 2018 grew by 8% from 2017, the total count of 2019 grew by 70%. Then what triggered the climate discourse so much on Twitter that year? Continue reading 2019 on Twitter: Climate activism awakening

Overstimulated by the news: How to navigate through times of crisis

by Susan Jörges

“Robert-Koch-Institute reports highest daily number of infections”, appears on the screen of my phone. The local newspaper lying on the kitchen table is titled with a similar headline, corona is issue number one in the evening TV-news, and my Instagram feed recommends a livestream of the government´s press conference.

What is a Climate Model?

by Felix Schaumann

Last August, our blogger Shorouk Elkobros explained what a climate model is in this video. One year later, climate models are still an essential tool for understanding global warming. In order to remind us how climate models work, Felix Schaumann has put together his own explanatory video.

Why we need airtravel for an accurate weather forecast

by Joana Kollert

Flying is bad for the climate – this is an uncontested fact. However, air traffic is necessary for weather forecasts, as airplanes send live data to weather stations. COVID-19 has caused a massive decline in air travel, hereby affecting the quality of weather forecasts.
