Climate: Uncertainty in scientific predictions can help and harm credibility

Science Daily: Climate News - 2 hours 8 min ago
The ways climate scientists explain their predictions about the impact of global warming can either promote or limit their persuasiveness.

Mapping global biodiversity change

Science Daily: Climate News - Thu, 10/17/2019 - 21:11
A new study which focuses on mapping biodiversity change in marine and land ecosystems shows that loss of biodiversity is most prevalent in the tropic, with changes in marine ecosystems outpacing those on land.

How aerosols affect our climate

Science Daily: Climate News - Thu, 10/17/2019 - 20:14
Greenhouse gases may get more attention, but aerosols -- from car exhaust to volcanic eruptions -- also have a major impact on the Earth's climate. Using a massive NASA dataset, researchers have created a framework that helps explain just how sensitive local temperatures are to aerosols.

Nature-based solutions can help protect us from climate-related natural hazards

Science Daily: Climate News - Thu, 10/17/2019 - 18:17
Solutions found in nature should be our first line of defense against the increasing number of climate change-related natural disasters, say experts.

First widespread chytrid fungus infections in frogs of Peruvian Amazon rain forests

Science Daily: Climate News - Thu, 10/17/2019 - 18:17
Biologists have documented, for the first time, the widespread presence of the notorious chytrid fungus in 80 species of frogs from lowland rain forest sites in the Peruvian Amazon.

Information theory as a forensics tool for investigating climate mysteries

Science Daily: Climate News - Thu, 10/17/2019 - 14:55
During Earth's last glacial period, temperatures on the planet periodically spiked dramatically and rapidly. A new article suggests that mathematics from information theory could offer a powerful tool for analyzing and understanding these mysterious events.

Tiny particles lead to brighter clouds in the tropics

Science Daily: Climate News - Wed, 10/16/2019 - 20:12
When clouds loft tropical air masses higher in the atmosphere, that air can carry up gases that form into tiny particles, starting a process that may end up brightening lower-level clouds, according to a new study. Clouds alter Earth's radiative balance, and ultimately climate, depending on how bright they are. The new paper describes a process that may occur over 40% of the Earth's surface.

Climate change increases risk of mercury contamination

Science Daily: Climate News - Wed, 10/16/2019 - 19:45
As global temperatures continue to rise, the thawing of permafrost is accelerated and mercury trapped in the frozen ground is now being released. The mercury is transforming into more mobile and potentially toxic forms that can lead to environmental and health concerns for wildlife, the fishing industry and people in the Arctic and beyond.

Galapagos study highlights importance of biodiversity in the face of climate change

Science Daily: Climate News - Wed, 10/16/2019 - 19:45
Study of wave turbulence suggests that highly mobile species and more diverse ecological communities may be more resilient to the effects of changing environmental conditions.

Are we underestimating the benefits of investing in renewable energy?

Science Daily: Climate News - Wed, 10/16/2019 - 16:49
Scientists have estimated the emissions intensity of carbon dioxide and other air pollutants from a major electricity distributor and highlighted key consequences - essential information for policymakers shaping decisions to reduce electricity system emissions.

Accelerating global agricultural productivity growth is critical

Science Daily: Climate News - Wed, 10/16/2019 - 14:47
The 2019 Global Agricultural Productivity Report, shows agricultural productivity growth -- increasing output of crops and livestock with existing or fewer inputs -- is growing globally at an average annual rate of 1.63%.  

Climate change concerns have largely ignored role of access to effective contraception

Science Daily: Climate News - Wed, 10/16/2019 - 02:29
Climate change concerns have largely ignored the importance of universal access to effective contraception, despite the impact of population growth on greenhouse gas emissions, argue experts.

Last year's extreme snowfall wiped out breeding of Arctic animals and plants

Science Daily: Climate News - Wed, 10/16/2019 - 00:15
In 2018, vast amounts of snow were spread across most of the Arctic region and did not melt fully until late summer, if at all. Researchers documented the consequences of this extreme weather event at Zackenberg, Northeast Greenland by extensively monitoring all components of the local ecosystem for more than 20 years, allowing them to compare life in the extreme year of 2018 to other, more 'normal,' years.

Increased risk of tularemia as the climate changes

Science Daily: Climate News - Tue, 10/15/2019 - 23:47
Researchers have developed a method for statistically predicting impacts of climate change on outbreaks of tularemia in humans. New results show that tularemia may become increasingly common in the future in high-latitude regions.

Two new porcelain crab species discovered

Science Daily: Climate News - Tue, 10/15/2019 - 23:47
Two new symbiotic porcelain crab species have been described. One of them, from the South China Sea of Vietnam, inhabits the compact tube-like shelters built by the polychaete worm with other organisms. The other inhabits the intertidal vermetid snail formations in the Colombian Caribbean.

Artificial intelligence and farmer knowledge boost smallholder maize yields

Science Daily: Climate News - Tue, 10/15/2019 - 23:46
Farmers in Colombia's maize-growing region of Córdoba had seen it all: too much rain one year, a searing drought the next. Yields were down and their livelihoods hung in the balance. To better deal with climate stress, farmers in Colombia's maize-growing region of Córdoba needed information services that would help them decide what varieties to plant, when they should sow and how they should manage their crops.

Targeting deeply held values crucial for inspiring pro-environmental behavior

Science Daily: Climate News - Tue, 10/15/2019 - 21:02
Given the alarming pace of climate change, it is increasingly important to understand what factors motivate people to take action - or not - on environmental issues. A recent study shows that deeply held values, which align closely with political leanings, can predict whether someone takes action to protect the environment.

Protein that triggers plant defences to light stress identified

Science Daily: Climate News - Tue, 10/15/2019 - 20:16
A newly discovered protein turns on plants' cellular defence to excessive light and other stress factors caused by a changing climate, according to a new study.

Study on climate protection: More forest -- less meat

Science Daily: Climate News - Tue, 10/15/2019 - 20:14
Forests help protect the climate. Reforestation can decisively contribute to mitigating global warming according to the Paris Agreement. Based on simulations, researchers have studied the conditions that should be fulfilled in Europe for this. According to the study, sufficient increase in forest areas requires a transformation of the food system and in particular, the reduction of meat consumption.

Strong storms generating earthquake-like seismic activity

Science Daily: Climate News - Tue, 10/15/2019 - 18:54
Researcher have uncovered a new geophysical phenomenon where a hurricane or other strong storm can spark seismic events in the nearby ocean as strong as a 3.5 magnitude earthquake.
