From apples to avocados: Producing food closer to cities could help reduce climate emissions
Millions of tons of groceries from agriculture are transported to our cities all around the globe every day. This food transport is linked to a huge amount of CO2 emissions. PIK scientist Jürgen Kropp explains options how to possibly reduce this “food-print”.
What saved the West Antarctic Ice Sheet 10,000 years ago will not save it today
The retreat of the West Antarctic ice masses after the last Ice Age was reversed surprisingly about 10,000 years ago - but given the rapid global warming we have observed over the last couple of 100 years or so, this won't help us to stabilize the ice shield from a collapse in these days, summarizes PIK scientist Torsten Albrecht.
Stronger evidence for a weaker Atlantic overturning
The Atlantic overturning – also called Gulf Stream System and one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards – is weaker today than any time before in more than 1000 years. PIK scientists Levke Caesar and Stefan Rahmstorf explain how they found out that the Gulf Stream System has slowed down.
Spacefood for cows
Industrial microbes could feed cattle, pigs and chicken with less damage to the environment: PIK scientist Benjamin Bodirsky gives insight how protein-rich microbes, produced in large-scale industrial facilities, could likely increasingly replace traditional crop-based feed.
