Achieving the COP21 agreements is currently far-fetched

9 de June 2017Albert Naya i Díaz

The COP21 set the maximum temperature increase for 2100 at 1.5° C. The only scenario which would allow achievement of this goal would require vastly reducing human CO2 emissions, significantly increasing the prominence of renewable energies, and the use of some type of artificial carbon sequestration technology.

#FenoDato seeks citizens to help monitor how climate change is altering nature’s rhythm

19 de January 2016Anna Ramon Revilla

Climate experts, botanists, geographers and ecologists from CREAF and the Autonomous University of Barcelona (UAB) will train citizens to monitor seasonal changes which can be observed in nature. This way citizens will be able to help the scientists study the effects of climate change on animals and plants. Flower emergence, the dropping of leaves, or the arrival of certain birds will be some of the changes to be studied. Once trained, citizens will be able to contribute to European and Spanish phenology observation networks.

Increased ozone levels reduce flowers’ sex appeal

17 de September 2015Anna Ramon Revilla

New research finds that as climate change increases ozone levels, pollinators will have a harder timing finding plants that feed them. That’s going to be a problem for the bees that pollinate a third of the world’s food supply. Flowers and other plants rely on microscopic scent molecules to attract the bees and other pollinators that feed on them. Climate change is going to disrupt that process, mostly because of ground-level ozone, which is projected to increase over the coming decades. The study, published in the journal New Phytologist, found that flowers’ fragile scent molecules break down more quickly as they are exposed to greater levels of ozone. >> Read the full article from Takepart.com here

The economic benefits of sustainable forestry in the Mediterranean region

22 de July 2014CREAF

Mediterranean forests provide local communities with a diverse range of products such as wood, fodder for livestock and plants and game, all of which contribute to food security and help to alleviate poverty in rural regions. However, these forests will be one of the most affected ecosystems in the near future as temperatures increase and rains decrease. In order to avoid the Mediterranean region turning into a desert, expert forest management is required.

What will the future smell like?

22 de July 2014Anna Ramon Revilla

Researchers from CREAF, CSIC, and the Institute of Agricultural and Environmental Sciences of Estonia have found that flowers are becoming more fragrant as the global mean temperature rises. In addition, intense heat provokes changes in the composition of floral aromas, transforming the odors of natural areas. This could lead to pollinizers mistaking the identity of flowers, especially specialist species whose flower visits are guided by their own innate olfactory preferences.
