KÆLTIA’s Team in its aim to contribute with the global awareness of the Climate Change, summarise below some critical news:
- Global agriculture both is one of the major drivers of climate change and strongly affected by it. Rising temperatures are among the main reasons for yield reductions. Therefore, the agricultural sector is faced with the major challenge of adapting to climate change in order to ensure food security in the future. According to a new study carried out by international researchers, the use of locally adapted cultivars can significantly contribute to achieve this goal. The study was led by LMU geographer Dr. Florian Zabel.
- The Arctic is losing ice as global temperatures rise, and that is directly affecting lives and triggering feedback loops that fuel more warming. But the big wild card for sea level rise is Antarctica. It holds enough land ice to raise global sea levels by more than 200 feet (60 meters) – roughly 10 times the amount in the Greenland ice sheet—and we’re already seeing signs of trouble. Scientists have long known that the Antarctic ice sheet has physical tipping points, beyond which ice loss can accelerate out of control. The new study, published in the journal Nature, finds that the Antarctica ice sheet could reach a critical tipping point in a few decades.
- Optimistic predictions expect reliable autonomous vehicles to be commercially available by 2030. New research shows that the convenience of autonomous vehicles would likely come at an environmental cost. Autonomous vehicles are expected to offer significant benefits in terms of transport operations, safety and accessibility; however, these benefits may mask potential environmental impacts: energy consumption, greenhouse gas emissions, particulates, and pollutants. To offset the environmental impacts of autonomous vehicles, the researchers from the University of Wisconsin-Madison considered the use of electric autonomous vehicles, considering the use phase only.
- Since it was first signed more than five years ago, the Paris Agreement has set the bar for the global effort to reduce greenhouse gas emissions, with more than 70 countries taking on ambitious nationally determined contributions that exceed initial commitments laid out in the agreement. However, a new paper released today in Proceedings of the National Academy of Sciences argues that the carbon budget these commitments are based on does not take into account the latest science on Arctic feedback loops, and calls for global leaders to rethink emissions goals.
- Data from the Jakobshavn drainage basin of the Central-Western Greenland ice sheet reveals that the distinct mark of this part of the ice sheet has reached a tipping point.
