CO2 emissions cause lost labor productivity

Science Daily: Climate News - Fri, 10/11/2019 - 20:18
Extreme high temperatures caused by CO2 emissions could lead to losses in labor productivity. The authors found that every trillion tons of CO2 emitted could cause global GDP losses of about half a percent. They add that we may already be seeing economic losses of as much as 2% of global GDP as a result of what we have already emitted.

New material captures carbon dioxide and converts it into useful chemicals

Science Daily: Climate News - Fri, 10/11/2019 - 18:22
The captured CO2 can be converted into useful organic materials.

Population aging to create pockets of climate vulnerability in the US

Science Daily: Climate News - Fri, 10/11/2019 - 18:22
Population aging projections across the US show a divide between cities and rural areas, which could lead to pockets of vulnerability to climate change.

Physics: An ultrafast glimpse of the photochemistry of the atmosphere

Science Daily: Climate News - Fri, 10/11/2019 - 16:59
Researchers have explored the initial consequences of the interaction of light with molecules on the surface of nanoscopic aerosols.

Fairy-wrens change breeding habits to cope with climate change

Science Daily: Climate News - Fri, 10/11/2019 - 16:59
Warmer temperatures linked to climate change are having a big impact on the breeding habits of one of Australia's most recognisable bird species.

New tool visualizes nature's benefits worldwide

Science Daily: Climate News - Thu, 10/10/2019 - 21:21
The researchers set out to understand where nature contributes the most to people and how many people may be affected by future changes. By 2050, up to 5 billion people could be at higher risk of water pollution, coastal storms and under-pollinated crops.

Sharing data for improved forest protection and monitoring

Science Daily: Climate News - Thu, 10/10/2019 - 19:56
Although the mapping of aboveground biomass is now possible with satellite remote sensing, these maps still have to be calibrated and validated using on-site data gathered by researchers across the world.

New study analyzes FEMA-funded home buyout program

Science Daily: Climate News - Thu, 10/10/2019 - 18:32
An analysis of FEMA's 30-year-old property buyout program offers new insight into the growing debate on managed retreat -- moving people and assets out of flood-prone areas.

Solution to Ice Age ocean chemistry puzzle

Science Daily: Climate News - Thu, 10/10/2019 - 16:57
New research into the chemistry of the oceans during ice ages is helping to solve a puzzle that has engaged scientists for more than two decades. At issue is how much of the CO2 that entered the ocean during ice ages can be attributed to the 'biological pump', where atmospheric carbon is absorbed by phytoplankton and sequestered to the seafloor as organisms die and sink.

Infectious disease in marine life linked to decades of ocean warming

Science Daily: Climate News - Wed, 10/09/2019 - 23:24
New research shows that long-term changes in diseases in ocean species coincides with decades of widespread environmental change.

Warm ocean water attacking edges of Antarctica's ice shelves

Science Daily: Climate News - Wed, 10/09/2019 - 21:29
Upside-down 'rivers' of warm ocean water are eroding the fractured edges of thick, floating Antarctic ice shelves from below, helping to create conditions that lead to ice-shelf breakup and sea-level rise, according to a new study. The findings describe a new process important to the future of Antarctica's ice and the continent's contribution to rising seas. Models and forecasts do not yet account for the newly understood and troubling scenario, which is already underway.

Electronic solid could reduce carbon emissions in fridges and air conditioners

Science Daily: Climate News - Wed, 10/09/2019 - 20:17
A promising replacement for the toxic and flammable greenhouse gases that are used in most refrigerators and air conditioners has been identified.

Predicting the impact of climate change on bridge safety

Science Daily: Climate News - Wed, 10/09/2019 - 14:53
Climate change will increase the frequency and intensity of natural hazards like flooding. In turn, floodwaters erode a bridge's foundation, creating scour holes that compromise the integrity of the structure. But to date, it's been possible to quantify that scour risk. A new model developed by civil engineering researchers takes a holistic approach combining climatology, hydrology, structural engineering, and risk assessment to determine the effects of climate change on bridges.

Study recommends special protection of emperor penguins

Science Daily: Climate News - Wed, 10/09/2019 - 04:21
Researchers recommend additional measures to protect and conserve one of the most iconic Antarctic species -- the emperor penguin (Aptenodyptes forsteri).

Using machine learning to understand climate change

Science Daily: Climate News - Tue, 10/08/2019 - 18:59
Methane is a potent greenhouse gas added to the atmosphere through both natural and human activities. To predict the impacts of human emissions, researchers need a complete picture of the methane cycle. Researchers used data science to determine how much methane is emitted from the ocean into the atmosphere each year. Their results fill a longstanding gap in methane cycle research and will help climate scientists assess the extent of human perturbations.

Study of past California wildfire activity suggest climate change will worsen future fires

Science Daily: Climate News - Tue, 10/08/2019 - 17:46
A new study finds that climate has been the dominant controller of wildfire activity in the Sierra Nevada region of the past 1,400 years, suggesting that future climate change is poised to make fires worse.

Believing in climate change doesn't mean you are preparing for climate change

Science Daily: Climate News - Tue, 10/08/2019 - 17:46
Researchers found that although coastal homeowners may perceive a worsening of climate change-related hazards, these attitudes are largely unrelated to a homeowner's expectations of actual home damage.

Heat waves could increase substantially in size by mid-century

Science Daily: Climate News - Tue, 10/08/2019 - 01:00
Scientists found that by mid-century, in a middle greenhouse emissions scenario, the average size of heat waves could increase by 50%. Under high greenhouse gas concentrations, the average size could increase by 80% and the more extreme heat waves could more than double in size.

Dual approach needed to save sinking cities and bleaching corals

Science Daily: Climate News - Mon, 10/07/2019 - 23:43
Local conservation can boost the climate resilience of coastal ecosystems, species and cities and buy them time in their fight against sea-level rise, ocean acidification and warming temperatures, a study by scientists suggests. In all but extreme situations, these interventions significantly buffer the impacts of climate change and can buy sinking cities and bleaching corals time to adapt until the beneficial impacts of global emissions reductions kick in.

Costs of natural disasters are increasing at the high end

Science Daily: Climate News - Mon, 10/07/2019 - 22:35
While the economic cost of natural disasters has not increased much on average, averages can be deceptive. The costs of major disasters like hurricanes Katrina, Maria and Dorian or the massive tornado swarms in the Midwest have increased to a disproportionately larger extent than those of lesser events, and these major disasters have become far more expensive, according to an international team of researchers.
