How Cities Can Adapt to Climate Change with Artificial Intelligence
The Freiburg project 'I4C - Intelligence for Cities' has developed locally precise climate models and foundations for planning tools Urban spaces are particularly susceptible to the effects of climate change, such as heat waves, floods, and storms. But which areas of a city are affected, and how can city planners respond? 'I4C - Intelligence for Cities' is an interdisciplinary project conducted by the University of Freiburg and several Fraunhofer Institutes.

Cool roofs are best at beating cities' heat
Cool roofs are best at beating cities’ heat
Painting roofs white or covering them with a reflective coating would be more effective at cooling cities like London than vegetation-covered "green roofs," street-level vegetation or solar panels, finds a new study led by UCL researchers. Conversely, extensive use of air conditioning would warm the outside environment by as much as 1 degree C in London's dense city centre, the researchers found.

Grasses in the Fog: Plants Support Life in the Desert
Grasses in the Fog: Plants Support Life in the Desert
Researchers from the Senckenberg Centre for Human Evolution and Palaeoenvironment (SHEP) at the University of Tübingen and the Senckenberg Natural History Museum in Görlitz have studied the role of the desert grass Stipagrostis sabulicola in the African Namib Desert. In their study, published in the journal Scientific Reports , they show that the plant is able to absorb moisture from fog events and thus forms an essential basis of an - altogether unexpectedly complex - food web in the drought-stricken landscape.

Researchers listen to the hearts of bats in flight
Researchers listen to the hearts of bats in flight
Researchers from Konstanz have measured the heart rate of bats over several days in the wild, including complete flights - the first time this has been done for a bat species. To record the heart rate of male common noctule bats during flight, the scientists attached heart rate transmitters weighing less than one gram to the animals, which they then accompanied in an airplane while the bats flew, sometimes for more than an hour, in search of food.

Treasures beneath the ocean floor? Seawater plays role in gold formation
Understanding how gold forms is crucial for knowing where to find it and how to extract it sustainably. McGill researchers have answered a long-standing question in geology that could lead to new ore discoveries. Researchers traveled to the remote Brucejack gold deposit in northwestern British Columbia to study and collect ancient ore-bearing rocks.

How to increase the rate of plastics recycling
A national bottle deposit fee could make a dramatic difference in reducing plastic waste, MIT researchers report. While recycling systems and bottle deposits have become increasingly widespread in the U.S., actual rates of recycling are "abysmal," according to a team of MIT researchers who studied the rates for recycling of PET, the plastic commonly used in beverage bottles.

Gulf fish more resilient to climate change than thought
Gulf fish more resilient to climate change than thought
Some fish species in the Arabian Gulf's coral reefs are more resilient to climate change than previously thought, an international team of scientists has found. The study, published in Nature Communications , challenges current scientific models which argue that by 2050, coral reef fish could shrink by 14-39 percent in size due to increasing temperatures under climate change.

Emissions Trading Also Creates Health Benefits
Emissions Trading Also Creates Health Benefits
The EU Emissions Trading System is not only good for reducing CO2 and for the climate. It also results in considerable health benefits due to reduced air pollution and saves hundreds of billions of euros, according to a recently released study by a team at Universität Hamburg. The research team from the Cluster of Excellence Climate, Climatic Change, and Society (CLICCS) at Universität Hamburg analyzed the indirect effects of the European Emissions Trading System (EU ETS) on hazardous air pollutants such as sulfur oxide, particulate matter, and nitrogen oxides.

Midnight sun on Svalbard: expedition to phytoplankton
On July 5, 2024, five researchers from Radboud University will travel to the far north to research climate change on Svalbard. For a week, the scientists, led by earth scientist Wytze Lenstra, will take samples of the sea floor and water column in one of the fjords. The archipelago is seen as a "natural laboratory" for studying the impact of climate change in the future: these Arctic regions are warming up to about four times faster than the global average.

UV and UPV researchers study the impact of climate change on bird productivity
Research staff from the Cavanilles Institute of Biodiversity and Evolutionary Biology of the Universitat de València and the Gandia Campus of the Universitat Politècnica de València have studied the consequences of climate change on the productivity of two species of passerine birds. The results show that extreme weather conditions, such as warmer temperatures and higher frequent torrential rainfall could threaten the preservation of the population of these birds.

How climate change is affecting where species live
As the climate warms, many species are on the move, raising new challenges for policy-makers around the world. Shifts in the ranges of mosquitoes and disease-bearing ticks and bats are introducing illnesses such as malaria and Lyme disease into regions where health-care systems are unprepared. Movements of commercially important fish from one jurisdiction to another are shifting job opportunities and causing trade disputes.

Light green hydrogen will do
Whether sustainably produced hydrogen needs to be 100 percent green is currently under debate. Using the production of ammonia and artificial fertiliser as examples, researchers have calculated that "nearly sustainable" hydrogen would be better in the end. There's a role for sustainably produced hydrogen in the energy transition, and not only as an energy storage medium or as fuel for lorries.

How humans transform island bird communities
It is known that people have been bringing alien bird species onto islands for thousands of years, but how this has shaped the diversity of those species has just been brought to light by a study soon to be published in the journal Ecology Letters. An international team of scientists led by three researchers from the CNRS and Paris-Saclay University 1 has shown that, on most of the 407 islands they considered, humans have a greater impact on alien species diversity than do geographic variables.
