Tiny airborne particles from wildfires have climate change implications

Thu, 09/05/2019 - 23:14
Wildfires are widespread across the globe. They occur in places wherever plants are abundant -- such as the raging fires currently burning in the Brazilian Amazon. Such biomass burning (BB) can be an environmental calamity. The smoke from BB events produces large amounts of aerosol particles and gases. These emissions can cause major problems for visibility and health, as well as for local and global climate.

Breakdown in coral spawning places species at risk of extinction

Thu, 09/05/2019 - 21:53
Synchronized coral spawning has become erratic, endangering the long-term survival of coral species, researchers say.

Climate change could bring short-term gain, long-term pain for loggerhead turtles

Thu, 09/05/2019 - 18:16
New research suggests that while some loggerheads will suffer from the effects of a changing climate, populations in certain nesting areas could stand to reap important short-term benefits from the shifting environmental conditions.

New patterns of key ocean nutrient

Thu, 09/05/2019 - 17:30
The important nutrient phosphate may be less abundant in the global ocean than previously thought, according to a new article. The researchers compiled data collected using highly sensitive techniques that measure phosphate to create a more accurate dataset to power global ocean models.

Diversity increases ecosystem stability

Thu, 09/05/2019 - 16:40
Forestry scientists demonstrate that forests that are more diverse are also more productive and more resilient.

Extreme weather events linked to poor mental health

Thu, 09/05/2019 - 15:01
People with homes damaged by extreme weather events are more likely to experience mental health issues such as depression and anxiety even when the damage is relatively minor and does not force them to leave their homes, a new study suggests.

Methane-producing microorganism makes a meal of iron

Thu, 09/05/2019 - 00:57
A new understanding of how a microorganism produces methane and carbon dioxide could eventually allow researchers to manipulate how much of these important greenhouse gases escape into the atmosphere.

Natural ways of cooling cities

Wed, 09/04/2019 - 23:52
Scientists have been researching the effect of precipitation and population size on rising temperatures in cities compared with the surrounding countryside. They have found that more green spaces can help to lower temperatures in urban zones -- but not everywhere.

From the tropics to the boreal, temperature drives ecosystem functioning

Wed, 09/04/2019 - 23:52
Researchers found a tight link between temperature and plant and microbe communities within forests, which will allow them to predict how ecosystems might respond to climate changes.

Solutions to urban heat differ between tropical and drier climes

Wed, 09/04/2019 - 20:56
In summer heat, cities may swelter more than nearby suburbs and rural areas. And while the size of this urban heat island effect varies widely among the world's cities, heat island intensity can largely be explained by a city's population and precipitation level, researchers have reported. The analysis suggests that cooling cities by planting more vegetation may be more effective in drier regions than in wetter ones.

Putting a price on carbon pollution alone unlikely to help reach climate goals

Wed, 09/04/2019 - 18:32
Researchers show that carbon taxes alone cannot reduce emissions enough to reach the Paris Agreement targets.

Climte concerns: It is best not to fly to conferences

Wed, 09/04/2019 - 17:08
A political scientist has developed a climate-friendly concept for international conference tourism.

New model predicts Painted Lady butterfly migrations based on breeding sites data

Wed, 09/04/2019 - 17:07
Researchers have developed a model that allows predicting the migratory movements of the Painted Lady butterfly between Europe and Africa based on data from breeding sites. This study confirms that populations need to continuously migrate to other latitudes to secure the best conditions for the immatures to grow.

Agrivoltaics proves mutually beneficial across food, water, energy nexus

Tue, 09/03/2019 - 16:14
Building resilience in renewable energy and food production is a fundamental challenge in today's changing world, especially in regions susceptible to heat and drought. Agrivoltaics, the co-locating of agriculture and solar photovoltaic panels, offers a possible solution, with new research reporting positive impacts on food production, water savings and the efficiency of electricity production.

New feedback phenomenon found to drive increasing drought and aridity

Tue, 09/03/2019 - 01:16
A new study indicates that the world will experience more frequent and more extreme drought and aridity than currently experienced in the coming century, exacerbated by both climate change and land-atmosphere processes. The researchers demonstrate that concurrent soil drought and atmospheric aridity are largely driven by a series of land-atmosphere processes and feedback loops. They also found that land-atmosphere feedbacks would further intensify concurrent soil drought and atmospheric aridity in a warmer climate.

Vintage film shows Thwaites Glacier ice shelf melting faster than previously observed

Tue, 09/03/2019 - 01:15
Newly available archival film has revealed the eastern ice shelf of Thwaites Glacier in Antarctica is melting faster than previous estimates, suggesting the shelf may collapse sooner than expected.

Impact of climate change on global banana yields revealed

Mon, 09/02/2019 - 18:36
Climate change could negatively impact banana cultivation in some of the world's most important producing and exporting countries, a study has revealed.

Oxygen depletion in ancient oceans caused major mass extinction

Fri, 08/30/2019 - 22:08
For years, scientists struggled to connect a mechanism to this mass extinction, one of the 10 most dramatic ever recorded in Earth's history. Now, researchers have confirmed that this event, referred to by scientists as the Lau/Kozlowskii extinction, was triggered by an all-too-familiar culprit: rapid and widespread depletion of oxygen in the global oceans.

Evidence for past high-level sea rise

Fri, 08/30/2019 - 22:07
Scientists, studying evidence preserved in speleothems in a coastal cave, illustrate that more than three million years ago -- a time in which the Earth was two to three degrees Celsius warmer than the pre-industrial era -- sea level was as much as 16 meters higher than the present day.

Early start of 20th century Arctic sea ice decline

Fri, 08/30/2019 - 22:07
Arctic sea-ice has decreased rapidly during the last decades in concert with substantial global surface warming. Both have happened much faster than predicted by climate models, and observed Arctic warming is much stronger than the global average. Projections suggest that Arctic summer sea-ice may virtually disappear within the course of the next fifty or even thirty years.
