Low economic growth can help keep climate change within the 1.5°C threshold, says study

A new study shows that economic growth rates make a big difference when it comes to prospects for limiting global warming to 1.5°C, as per the Paris Agreement. A recent study by the Institute for Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) shows that pursuing higher economic growth may jeopardize the Paris goals and leave no viable pathways for humanity to stabilize the climate. On the contrary, slower growth rates make it more feasible to achieve the Paris goals.

Scanner data can help New York state farmers boost market sales
