Direct CO2 Capture Machines Could Use ‘a Quarter of Global Energy’ in 2100
By Simon Evans
Machines that suck CO2 directly from the air could cut the cost of meeting global climate goals, a new study finds, but they would need as much as a quarter of global energy supplies in 2100.
Global CO2 emissions from fossil fuels (Gt/yr) in model pathways consistent with limiting warming this century to 1.5 C (left panel, blue) or 2 C (right panel, green). Results from two different IAMs – TIAM and WITCH – are shown with solid and dashed lines, respectively. The various lines show scenarios that use direct capture ("DAC," darker shades) and those that do not ("NoDAC," lighter), as well as pathways to 2 C without negative emissions of any sort ("NoNET," darkest green).

The U.S. has recently experienced one of its worst tornado outbreaks of the past decade, with more than 500 reported over 30 days. The number so far this year is also more than 200 above average.
This has raised the question of what role, if any, climate change may have played in this unusually intensive period of tornadoes. While some have suggested that climate change is driving the above-average numbers, the scientific community has pushed back on these claims.
Understanding and attribution of climate change impacts on extreme events, by event type.

Like many other plant-based foods and products, CBD oil is one dietary supplement where "organic" labels are very important to consumers. However, there are little to no regulations within the hemp industry when it comes to deeming a product as organic, which makes it increasingly difficult for shoppers to find the best CBD oil products available on the market.

The IEA's Coal 2018 report finds that global coal demand grew by 1 percent in 2017 after two years of decline. The rise was chiefly driven by global economic growth, it says. Despite recent growth, demand is still below "peak" levels seen in 2014.
Demand is likely to "remain stable" until 2023, the report authors say. This is because falling demand in western Europe and North America is likely to be offset by increased demand in a host of Asian countries, including India, Indonesia and Vietnam.
Carbon Brief takes a look at the IEA's changing coal forecasts for key world regions.

Arctic sea ice has reached its summer minimum extent for the year, clocking in at 4.59m square kilometers (sq km) (approximately 1.77m square miles), which puts it joint sixth lowest in the 40-year satellite record alongside 2008 and 2010.
The twelve smallest summer lows in the satellite record have all occurred in the last twelve years.
Limiting Warming to 2°C Would Prevent ‘Worldwide Increases’ in Heat-Related Deaths

Restricting global warming to 2°C above pre-industrial levels would prevent large increases in temperature-related deaths across much of the globe, a new study finds.
And keeping warming to 1.5°C—the aspirational target of the Paris agreement—would further limit the number of people dying from temperature extremes in some parts of the world, including in southeast Asia and southern Europe.

The UK could cut its emissions to "net-zero" within the next three decades by stepping up investment into technologies that can remove CO2 from the atmosphere, a report finds.
However, such methods, which are known collectively as "negative emissions technologies" (NETs), would only be effective if paired with drastic efforts to cut the UK's current rate of emissions, the findings suggest.
After a summer full of extreme weather headlines, The BBC is making a concerted effort to improve its coverage of climate change.

The vast mangroves of the Amazon store twice as much carbon per hectare as the region's tropical forests, new research shows.
The relatively understudied ecosystem also stores 10 times more carbon than Amazon savannahs—a type of grassy plain with sparsely populated trees, according to the study.

Sharp declines in summer rainfall could be a "primary driver" of the record-breaking wildfires ripping across the western U.S., research shows.
Using satellite data, the study finds that there have been "previously unnoted" declines in summer rainfall across close to a third of forests in the western U.S. over the past four decades. These declines are "strongly correlated" with wildfire increases, the study finds.

Releasing aerosols into the atmosphere in order to limit the rise in global temperature would not stave off damage to crop yields, a new study suggests.
Scientists have suggested that intentionally releasing aerosols into the atmosphere—a type of "solar geoengineering"—could help to limit global warming by reflecting away incoming sunlight in a similar way to a volcanic eruption.

Scientists studying the troposphere—the lowest level of the atmosphere—have found "powerful evidence" that climate change is altering seasonal temperatures.
A study published in Science finds that climate change has caused an increase in the difference between summer and winter temperatures across North America and Eurasia over the past four decades.
