Hmm...

Because this Daily Kos community article seems up Red Baron Farms' alley, though likely not telling him anything especially new, I feel like linking to it so he can take a look if he wants and judge it for himself. Really short summation, Biden apparently mentioned "cover crops" and this person decided to try to give a short run down of what they are, how beneficial they are, how valuable soil can be for handling climate change, and some government actions related to that.

Thanks and you are correct. It's a pretty basic primer. However, if it helps people understand, all good.

Personally I prefer actually stating what is happening with more scientific terminology. Even if it is new knowledge, it seems people learn it faster when they can use the proper terms like Arbuscular Mycorrhizal Fungi, and Saprophytic Fungi, symbiosis etc.... instead of generic and vague "beneficial microorganisms".

When the article author says things like this, it seems to me to be talking down to the reader, and purposely making it too vague to have any possibility to understand. Just my opinion though. The article is basically correct. It's just not very useful in my opinion. Maybe the author could have explained it better if they had more space available?
 
LA County doesn't have enough prison slaves, because of the pandemic, in order to fight wildfires. Beyond parody.

He said L.A. County would normally have 24 inmate firefighting crews but is down to eight, as many were sent home from prison after the state granted them early release because of the pandemic. That has forced the department to dip into its budget to train more paid crew members, he said.

It's got a bit madly hot in Canada, setting new records by a hell of a margin.
Weather is not climate Mr. Clingford.

Careful not to make the same mistake deniers make when a record cold snap hits. (We had a few here like that in Oklahoma too.)

But yes, if the trends hold true over long periods of time, doesn't look good for certain parts of Canada.

I believe they are saying the loss of perennial ice in the arctic is effecting ocean currents, which then effects air currents and land temperatures. If this complexity winds up being true, it will not be good for the ecosystems adapted to milder temps but now existing in very different climatic conditions. Not time enough to adapt and change without significant ecosystem damage.

There are ways to investigate whether a weather event is likely related to climate change. Over the last 2 decades there have been several heat waves that turned out to have a high probability of being climate change related.

The numbers haven't been crunched on this one yet to the warning on weather vs climate are wroth noting but given the severity of the heat wave I would not be surprised if this one turns out to be climate related. We won't know either way for a year or more.

I would not be surprised either. I just prefer to take a cautionary approach and wait till we have a better idea.

Yeah some caution is advisable, but the scale of this heatwave is crazy. Lytton BC just set new Canadian temperature records for the third day in a row. Yesterday it hit 49.6 deg C (121.3 Def F), only a few higher temperatures have ever been reliably recorded in the America's. The places to have recorded higher temperatures are all in the desert regions of the US southwest or across the border in Mexico. Lytton isn't in a desert like Las Vega (all time high of 117Deg F) or Phoenix (122 Deg F). Lytton is located on the Frazer River in the middle of the Rocky Mountains.

Whether it ends up being attributed to global warming or not, this is a remarkable climate story.
 
It's the sheer margin of the new records that is astounding. If I were talking to a sceptic/denier I would indeed talk about trends. But this is just off the charts.

Haven't seen you for a while, mate!

It's also killing more oldies than Covid. They're dropping like flies, which was entirely predictable, given Canadian residences aren't built for extreme heat.

I made the comment on another forum that Canada's new all-time high (at latitude 53 deg N) is over two degrees hotter than the hottest temperature ever recorded in Alice Springs.

Alice is bang in the middle of Australia, latitude 23 deg S.

And nobody's even mentioned the heatwave in Siberia which is even further above normal than Canada/USA.

Weather is not climate Mr. Clingford.

Oh, bollocks.

Climate science has predicted more and hotter heatwaves for a long time, and these are the direct result of that science coming true.

Word from the experts
Rapid attribution of PNW heatwave
Filed under: Climate impacts Climate modelling Climate Science heatwaves Instrumental Record statistics — group @ 7 July 2021
Summary: It was almost impossible for the temperatures seen recently in the Pacific North West heatwave to have occurred without global warming. And only improbable with it.

It’s been clear for at least a decade that global warming has been in general increasing the intensity of heat waves, with clear trends in observed maximum temperatures that match what climate models have been predicting. For the specific situation in the Pacific NorthWest at the end of June, we now have the first attribution analysis from the World Weather Attribution group – a consortium of climate experts from around the world working on extreme event attribution. Their preprint (Philip et al.) is available here.

U.N. climate panel confronts implausibly hot forecasts of future warming
By Paul VoosenJul. 27, 2021 , 4:50 PM
Next month, after a yearlong delay because of the pandemic, the U.N. Intergovernmental Panel on Climate Change (IPCC) will begin to release its first major assessment of human-caused global warming since 2013. The report, the first part of which will appear on 9 August, will drop on a world that has starkly changed in 8 years, warming by more than 0.3°C to nearly 1.3°C above preindustrial levels.

so much for 1.2 :rolleyes:
 
Meanwhile, two big pieces of news from Australia:

Australia’s energy market operator plans for net zero by 2050 as Morrison stalls

Aemo says new planning scenarios, including a ‘hydrogen superpower’ option, reflect accelerating transition in energy market


While Scott Morrison is yet to give a formal commitment to achieving net zero by 2050, Australia’s energy market operator has added the mid-century scenario to its forward planning.

In its latest Inputs, Assumptions and Scenarios Report, released on Friday, the Australian Energy Market Operator (Aemo) has added new planning scenarios – including net zero by 2050 and a “hydrogen superpower” option.

Aemo’s chief system design officer, Alex Wonhas, said the updated scenario planning reflected the accelerating transition in Australia’s energy market and “overwhelming” calls from stakeholders for the energy market operator to produce scenarios “to reflect the observed rapid decarbonisation of the energy sector and pathways to achieve net-zero emissions across the economy”.

Stakeholders say Aemo initially floated a more prominent transitional role for gas in line with the Morrison government’s “gas-fired recovery” rhetoric, but this idea was resisted during consultation. Aemo spent 10 months consulting with consumer groups, governments, individuals and industry on its plans.

Origin Energy slashes value of Australia’s biggest coal-fired plant due to impact of cheap renewables

Shares tumble after company announces $1.5bn asset writedown and lower expected earnings


Origin Energy has slashed the value of its assets, including Australia’s biggest coal-fired power plant, by more than $1.5bn as cheap power from renewables floods the national grid.

Company shares tumbled as much as 10% on Friday morning after Origin announced the writedown and lower expected earnings next year to the Australian Securities Exchange, before recovering slightly to be down about 7.85% about 12.45pm.

Origin owns Eraring power station in New South Wales. It is the company’s and the nation’s biggest coal-fired power plant, supplying NSW with about 25% of its electricity.

In a statement to the ASX, the company said it had cut the value of its power stations by $583m due to lower power prices “driven by new supply expected to come online, including both renewable and dispatchable capacity, impacting the valuation of the generation fleet, particularly Eraring power station”.
