How global warming might affect food security – The Hindu

Between the year 1870 (the first industrial revolution) and today, the global temperature has risen by almost 2 degrees Celsius. This has come about due to more fossil burning (oil, natural gas, coal), which has also increased the carbon dioxide…

Red maples doing better in the city

A new study examines how trees respond to different urban intensities by comparing tree size and age, foliage nitrogen signature, nutrient and heavy metal content and other factors in forests. Not only were the trees acclimated to urban conditions in the higher density Philadelphia forests, but the red maples there were actually healthier and more productive compared to those surrounded by less urbanization in Newark.

Unprecedented energy use since 1950 has transformed humanity’s geologic footprint

(University of Colorado at Boulder) A new study makes clear the extraordinary speed and scale of increases in energy use, economic productivity and global population that have pushed the Earth towards a new geological epoch, known as the Anthropocene.

Artificial cyanobacterial biofilm can sustain green ethylene production for over a month

Ethylene is one of the most important and widely used organic chemicals. A research group has designed a thin-layer artificial biofilm with embedded cyanobacterial cell factories which were specifically engineered for photosynthetic production of ‘green’ ethylene. The fabricated biofilms have sustained ethylene production for up to 40 days.

Rainforest model offers glimpse into future of the Amazon

Tropical Forests may be more resilient to climate change than previously thought, according to ecologists. The results help solve an ongoing debate about the mechanism responsible for declines in tropical forest productivity that go hand in hand with rising global temperatures.

Adapting to 4°C of global warming – GOV.UK – GOV.UK

Before I start my speech, I’d like to add my condolences to the Committee on Climate Change and everyone who knew Professor Dame Georgina Mace. Georgina’s work assessing the impacts of climate change and the effect of adaptation on the…

School absences correlate to impaired air quality

(University of Utah) In Salt Lake City schools, absences rise when the air quality worsens, and it’s not just in times of high pollution or “red” air quality days–even days following lower levels of pollutions saw increased absences.

CRISPRing trees for a climate-friendly economy

Researchers have discovered a way to stably fine-tune the amount of lignin in poplar by applying CRISPR/Cas9 technology. Lignin is one of the main structural substances in plants and it makes processing wood into, for example, paper difficult.

Cyanobacteria as ‘green’ catalysts in biotechnology

Researchers show how the catalytic activity of cyanobacteria, also known as blue-green algae, can be significantly increased. This brings biotechnological and thus eco-friendly application a big step closer.
