Free electric vehicle charging at work? It's possible with optimum solar      (via sciencedaily.com)     Original source 

The global surge in electric vehicle sales has prompted an Australian university to explore how it could offer free or nominal EV charging facilities to staff and students by optimizing its solar PV system and minimizing workplace electricity costs.

New study sheds light on how much methane is produced from Arctic lakes and wetlands      (via sciencedaily.com)     Original source 

New study looked at lakes in the Arctic, including those at Alaska's Yukon Flats National Wildlife Refuge, to shed light on how much methane is produced from Arctic lakes and wetlands. Small unmapped lakes in the Arctic are far less abundant than previously thought, greatly reducing the cumulative methane emissions they were thought to contribute to Earth's atmosphere.

New geophysical technique enhances imaging of fluid-filled rocks finding connections with microearthquakes      (via sciencedaily.com)     Original source 

Scientists have recently introduced a new method called ambient noise differential adjoint tomography, which allows researchers to visualise rocks with fluids better, leading to potential advancements in the discovery of water and oil resources, as well as applications in urban geologic hazard and early warning systems for tsunamis and the understanding of the water cycle.

Have researchers found the missing link that explains the mysterious phenomenon known as fairy circles?      (via sciencedaily.com)     Original source 

Fairy circles, a nearly hexagonal pattern of bare-soil circular gaps in grasslands, initially observed in Namibia and later in other parts of the world, have fascinated and baffled scientists for years. New research suggests that all theories to date have overlooked the coupling between two robust mechanisms essential for understanding ecosystem response: phenotypic plasticity at the level of a single plant, and spatial self-organization in vegetation patterns at the level of a plant population.

Climate change will increase wildfire risk and lengthen fire seasons      (via sciencedaily.com)     Original source 

Wildfires are some of the most destructive natural disasters in the country, threatening lives, destroying homes and infrastructure, and creating air pollution. In order to properly forecast and manage wildfires, managers need to understand wildfire risk and allocate resources accordingly.

Adapting to hypoxia: Zooplankton influence the efficiency of the biological carbon pump in the Humboldt Current off Peru      (via sciencedaily.com)     Original source 

Marine organisms play a crucial role in the global carbon cycle. Phytoplankton absorb carbon dioxide from the atmosphere and sequester it in organic matter that sinks to the deep ocean where it can be stored for long periods of time. Until now, this process -- the biological carbon pump -- was thought to be particularly efficient in oxygen-poor areas. A new study suggests that the influence of certain zooplankton species on the biological carbon pump has been underestimated.

Protected areas in Thailand are at a higher risk of forest fires when located away from indigenous communities      (via sciencedaily.com)     Original source 

Research has found that national parks and protected areas are at a higher risk of forest fires when located farther away from indigenous communities. Based on the analysis of satellite images from Thailand and case studies from other Southeast Asian countries, the research demonstrates that policymakers can achieve improvements in forest health by working collaboratively with indigenous communities. Involving communities results in reduction of forest fires and air pollution.

Feathered friends can become unlikely helpers for tropical coral reefs facing climate change threat      (via sciencedaily.com)     Original source 

Tropical coral reefs are among our most spectacular ecosystems, yet a rapidly warming planet threatens the future survival of many reefs. However, there may be hope for some tropical reefs in the form of feathered friends. A new study has found that the presence of seabirds on islands adjacent to tropical coral reefs can boost coral growth rates on those reefs by more than double.

Climate change shown to cause methane to be released from the deep ocean      (via sciencedaily.com)     Original source 

New research has shown that fire-ice -- frozen methane which is trapped as a solid under our oceans -- is vulnerable to melting due to climate change and could be released into the sea.

Greenhouse gases in oceans are altered by climate change impact on microbes      (via sciencedaily.com)     Original source 

The ocean is a global life-support system, and climate change causes such as ocean warming, acidification, deoxygenation, and nitrogen-deposition alter the delicate microbial population in oceans. The marine microbial community plays an important role in the production of greenhouse gases like nitrous oxide and methane. Scientists have explored the climate change impact on marine microbes. Their research helps raise awareness about climate change severity and the importance of ocean resources.

The ocean may be storing more carbon than estimated in earlier studies      (via sciencedaily.com)     Original source 

The ocean's capacity to store atmospheric carbon dioxide is some 20% greater than the estimates contained in the latest IPCC report. Scientists looked at the role played by plankton in the natural transport of carbon from surface waters down to the seabed. Plankton gobble up carbon dioxide and, as they grow, convert it into organic tissue via photosynthesis.

Artificial light is luring birds to cities and sometimes to their deaths      (via sciencedaily.com)     Original source 

Scientists used weather radar data to map bird stopover density in the United States and found that artificial light is a top indicator of where birds will land. City lights lure birds into what can be an ecological trap -- with buildings that lead to collisions, less habitat, scarcer food, and more people and cats. The study provides the first continent-wide maps of migration stopover hotspots in the contiguous United States, and knowing these broadscale layover patterns can help in the development of conservation plans.

Crocodile family tree mapped: New light shed on croc evolution      (via sciencedaily.com)     Original source 

Around 250 million years ago, 700 species of reptiles closely related to the modern-day crocodile roamed the earth, now new research reveals how a complex interplay between climate change, species competition and habitat can help explain why just 23 species of crocodile survive today.
