Fact Brief - Does breathing contribute to CO2 buildup in the atmosphere?:

 
Fact Brief - Does breathing contribute to CO2 buildup in the atmosphere? - Skeptical Science
May 18 · Fast cycling of carbon is seasonal. CO2 increases in colder months when plants decay and release their carbon. In the warmer months, CO2 decreases as plants take it in, along with sunlight, to produce energy and oxygen. Animals — including humans — eat plants, breathe in oxygen, and exhale CO2. Graphs of CO2 show a wave pattern reflecting this seasonal change.
Fossil fuels are part of the slow carbon cycle that operates over geological timescales. Burning fossil fuels takes carbon stored in the slow cycle and introduces it into the fast one. This activity is unique in Earth’s history; no other life-form has done anything on the same scale.

GPS Stations Measure Daily Ice Loss in Greenland - Science Daily - Earth and Climate
May 24 · When the ice sheet in Greenland melts, as it has done increasingly in recent years, the bedrock beneath moves slightly.
This occurs because the pressure from the ice above decreases, causing the land beneath to rise. This elevation change can be measured and translated into how much ice disappears from Greenland's ice sheet and how fast it's happening. Now, researchers at the Technical University of Denmark (DTU) have developed a method based on this principle, allowing daily tracking of ice melt for the first time.

Microplastics may slow the rate at which carbon is pulled from the sea surface to the depths - PHYS.ORG - Earth
May 17 · A new study co-authored by Northeastern researcher Aron Stubbins shows that microplastics may reduce the ability of the ocean to help offset the climate crisis by slowing down the rate at which carbon is taken from the sea surface to the depths.
For millennia, the ocean has been part of a carbon sink process in which dead phytoplankton clump together and fall into the deep ocean in showers of what look like "marine snow," says Stubbins, a professor of marine and environmental science.
The resulting carbon sequestration is a marine version of how trees and plants on terrestrial Earth take carbon from the atmosphere and store it in soil, he says.

There was no immediate threat to oil sands mines but production of more than 2 million barrels per day could be in jeopardy if the situation worsens.
Meanwhile, greenhouse emissions from the fires across Western Canada have hit a new high.
Alberta Wildfire spokeswoman Josee St-Onge told a news conference a fire southwest of Fort McMurray was still considered out of control, after scorching almost 21,000 hectares (52,000 acres) of forest.
But it has not gotten any closer to the city since ...

What Honda's big electric vehicle announcement in Ontario really means - PHYS.ORG - Technology
May 16 · In 2010, Ontario's economic future looked grim. Tied as it had been for more than a century to the automobile industry, the provincial economy was in freefall.
General Motors and Chrysler went bankrupt, dozens of plants were shuttered, and tens of thousands of well-paying auto jobs were lost along Ontario's automotive-producing zone from Windsor to Oshawa.
Ontario's auto sector, once the wellspring of the province's prosperity, looked to be in the process of an inevitable decline. It was, quite literally, a dinosaur industry seemingly destined to go the way of Australia's, which closed its last car plant in 2017.
Barely 15 years later, in April Honda announced a ...

What Is the Carbon Footprint of a House in Japan? - Science Daily - Earth and Climate
May 24 · The team hopes that by identifying emission hot spots in the supply chain that go into building a house, policy makers can implement strategies to reduce its climate impact. Their analysis was published in the Journal of Environmental Management.
As humanity maneuvers itself through the climate crisis, researchers and industry professionals alike have been working to identify sectors with high CO2 emissions so they can implement policies that potentially reduce greenhouse gas production. But in today's highly interconnected economy, figuring out a sector or object's greenhouse gas output is astoundingly complex.
"For example, it's easy to calculate how much CO2 a single ...

What made the deadly thunderstorms in Houston so violent? - Washington Post - Climate and Environment
May 17 · Several meteorological ingredients, including record-warm land and ocean temperatures from the Florida Keys to Mexico, helped fuel the destructive storms.
Texas is no stranger to strong thunderstorms this time of year. It was a confluence of multiple factors, however, that primed the atmosphere for the exceptionally intense storms that blasted the Houston area Thursday evening, killing at least four people, downing trees, cutting power to more than 870,000 customers and blowing out skyscraper windows.

Why cheap renewables are stalling - PHYS.ORG - Technology
May 16 · The warnings of climate scientists are at fever pitch: halt the burning of coal, oil and gas or risk catastrophic warming of at least 2.5°C. With solar and wind energy plentiful and supposedly cheap to harvest, why is ditching fossil fuel so hard anyway?
Renewable sources generate nearly a third of the world's electricity—and a handful of new studies suggest that rapidly decarbonizing the remainder is possible.
In fact, some evidence suggests the transition needn't be all that painful.
Shovels at the ready
"Over half of Africa's people—about 600 million—lack access to even the bare minimum of electricity," say Christiane Zarfl and ...

Wildfire closes in on Canadian oil sands city - PHYS.ORG - Earth
May 16 · A wildfire in Canada's major oil-producing region doubled in size as it drew closer to the city of Fort McMurray on Wednesday, but officials were hopeful shifting winds could soon push it away.
The blaze scorched almost 21,000 hectares (52,000 acres) of forest overnight as it came within 4.5 kilometers (2.8 miles) of the city, which was partly evacuated the day before.
Alberta Wildfire spokeswoman Christie Tucker told a briefing that cooler temperatures and calmer winds were expected to "push the fire away from Fort McMurray" as well as weaken it.
However, Alberta Public Safety Minister Mike Ellis urged residents to "remain vigilant," noting that "wildfire ...

Wildfires keep thousands evacuated in Canada, even as conditions improve - Washington Post - Climate and Environment
May 15 · Blazes across Canada continued burning out of control, though weather improvements Wednesday aided firefighting efforts.
More than 100 wildfires were burning in Canada on Wednesday, and thousands of residents in rural communities choked by the worst blazes remained evacuated, even as improving weather allowed firefighters to make some progress.
With hundreds of thousands of acres burning, 35 fires were listed as out of control by the Canadian Interagency Forest Fire Center as of Wednesday afternoon. The day brought cooler temperatures and minor precipitation, which helped keep a massive blaze near Fort Nelson, B.C., from spreading further and slightly calmed the ...

Wind Farms Can Offset Their Emissions Within Two Years:

 
Wind Farms Can Offset Their Emissions Within Two Years - Science Daily - Earth and Climate
May 24 · After spinning for under two years, a wind farm can offset the carbon emissions generated across its entire 30-year lifespan, when compared to thermal power plants.
That's according to a new peer-reviewed study published in the Journal of the Royal Society of New Zealand -- which also shows within six months a turbine can generate all the energy consumed across its life-cycle.
"The wind turbine technology employed in New Zealand is consistent with that used internationally," explains lead author Isabella Pimentel Pincelli from the Sustainable Energy Systems research group, Wellington Faculty of Engineering, at Te Herenga Waka Victoria University of ...
