NOAA confirms 2016 as hottest year on record for the planet.

The US federal government has published the State of the Climate, the annual report is prepared by more than 450 scientists from more than 60 countries around the world and published in conjunction with the American Meteorological Society. It's the most comprehensive annual summary of Earth's climate.

Just to better understand what the chart means: Does (for instance) the item "plant rich diet" mean that the benefits they show will be achieved if ALL people adopt a plant rich diet?.....or does it mean that somehow the authors think they know that it is reasonable to predict that x percent of people could be induced to take up a plant rich diet? I guess the overarching question I have is: Is there any consideration here on the likeliness of any of these items occuring and if not then it would be good for us to study which of these items are more amenable to implementation. Please note that I am well aware that "every little bit helps"....but I am also aware that if too much attention is spent on the "little bits" it is unlikely that the problem will be solved.

There's a lot of work behind that chart, chownah, and I think we really need to visit the site and explore it, but the items are ranked according to how much CO2 reduction each of them can plausibly achieve (column at right), so the simple answer is that items near the top of the list will give us the most bang for the buck.
And if we're not engaged in climate action at the professional level, our best strategies are to encourage and promote all the top items and adopt as many of them as we can, as far as we can - always within reason, of course. If we don't do anything else, we can move towards a plant-rich diet ourselves; if we want to do more, we might take our money out of coal mines to invest in wind-farms and solar farms, or donate to charities which focus on educating girls in developing nations; etc.
And, as you say, every bit helps!

What Makes an Elder? :
A head of gray hairs doesn't mean one's an elder. Advanced in years, one's called an old fool.
But one in whom there is truth, restraint, rectitude, gentleness,self-control, he's called an elder, his impurities disgorged, enlightened.

A game-changer from China:
China to ban production of petrol and diesel cars 'in the near future'

Announcement aimed at tackling pollution will prove a huge incentive to development and sale of electric and hybrid vehicles

China, the world’s biggest vehicle market, is considering a ban on the production and sale of fossil fuel cars in a major boost to the production of electric vehicles as Beijing seeks to ease pollution. ... Xin Guobin, vice-minister of industry and information technology, told a forum in the northern city of Tianjin at the weekend that his ministry had started “relevant research” and was working on a timetable for China.

Xin said the policy would be implemented “in the near future”, according to the official Xinhua news agency. ...

As the measure looms, foreign vehicle manufacturers have announced plans to boost the production of electric cars in China.
Volvo will introduce its first 100% electric car in China in 2019, while Ford will market its first hybrid vehicle early next year and envisions 70% of all its cars available in China will have electric options by 2025.
https://www.theguardian.com/world/2017/ ... ear-future
If Ford can voluntarily say "2025", I reckon China is going to push them to do it faster - and push Chinese companies to beat Ford to it anyway. :smile:

Maria:
Hurricane Maria has made landfall on the Caribbean island of Dominica as a dangerous category five storm, the US National Hurricane Centre (NHC) said.

Maria was packing maximum sustained winds of 260 kilometres per hour, placing it at the top level of the Saffir-Simpson hurricane and wind scale, the Miami-based forecaster said in its latest advisory.

A bit warm recently?
Century-old records across the Midwest and East Coast are being shattered by a monster late-September heat wave ...
“Summer in some regions of the world will become one long heatwave even if global average temperatures rise only 2°C [3.6ºF] above pre-industrial levels,” finds a study published Monday in Nature Scientific Reports. ...
On Wednesday, another study showed the connection between deadly heat waves and climate change. Scientists with World Weather Attribution (WWA) released an analysis of Europe’s blistering summer heat, which included the heat wave so deadly it was nicknamed “Lucifer.” The researchers found, “climate change increased the chances of seeing a summer as hot as 2017 by at least a factor of 10 and a heat wave like Lucifer by at least a factor of four since 1900″ (emphasis in original). ...
“It’s perhaps obvious that global warming means more frequent and intense heat waves,” climatologist Michael Mann noted in an email to ThinkProgress. “But what is less obvious is how climate change may be impacting the behavior of the jet stream in way that causes more persistent weather extremes, giving us even more extreme and longer-duration heat waves than we would otherwise expect.”

The National Weather Service tweeted out a chart showing this very effect. ...

... the new Nature Scientific Reports study finds that for each additional 1.8°F of global warming during the summer, there would likely be:

15 to 28 more heat wave days each year
Heat waves would last 3 to 18 days longer
The peak intensity of heatwaves will increase 2.2°F to 3.4°F

But while the rest of the world is working to limit additional warming as much as possible, Trump’s policies would take us to upwards of 5.4°F or more additional warming. ...
https://thinkprogress.org/september-hea ... 1143e97e1/

For the (tumbling) record, my own state is also experiencing record temperatures this week -
September temperature records were broken in south-east Queensland as the mercury soared above 40 degrees Celsius in parts of the region.

Bureau of Meteorology forecaster Steve Hadley said new records were set west of Brisbane when it reached 40.1 degrees in Ipswich, as well as 39.5 in Gatton and 39.5 in Beaudesert.

We're due for some good news ...
This one - https://blogs.scientificamerican.com/sa ... an-energy/ - is good for the world but not very complimentary about the US. It begins with this graph:
renewables-montanez.png
renewables-montanez.png (50.22 KiB) Viewed 1327 times
...the data speak for themselves. While global 2025 targets require more action across the board, recent U.S. decisions such as scaling back the Clean Power Plan, pulling out of the Paris Agreement, and promoting the oxymoronic figment known as “clean coal,” point us squarely in the wrong direction. And as we fall behind, the world will look instead to China as a model for a more sustainable future. ...
This one - http://grist.org/briefly/good-news-glob ... t-in-2016/ - is short enough to quote in full, so I will:
Good news! Global carbon emissions stayed flat in 2016.

This marks the third year in a row with no increase in CO2 emissions, according to a new report published from the Netherlands Environmental Assessment Agency. That’s largely due to a shift away from coal to natural gas, which tends to produce more electricity more efficiently, and renewable energy.

Enough good news. Here’s the bad: When you add the potent greenhouse gas methane to the mix, global emissions were up .5 percent. Methane emissions primarily come from natural gas leaks (see Aliso Canyon) and cattle. Also, this report does not count the forests felled and peatlands burned which likely bumps the numbers up. Finally, halting the growth in emissions isn’t good enough — we’ve got to drive them down.

Nonetheless, climate economist Nicholas Stern told the Guardian, “These results are a welcome indication that we are nearing the peak in global annual emissions of greenhouse gases.” The world has hit the brakes on what looked like unstoppable emissions growth. For the first time in the modern era, the economy is growing without increasing the amount of CO2 it spews into the air.

Trump is doing all he can - https://www.nytimes.com/interactive/201 ... ersed.html - to roll back Obama's good work.
Fortunately, almost everyone else in positions of power is doing all they can to maintain and extend it.

More on Caribbean hurricanes fyi -
As a Caribbean climate scientist, I am often asked to speak about how climate change affects small islands. In the aftermath of Hurricane Maria, one of two category five storms to batter the eastern Caribbean in just a week, three words resonate in my mind.

The first word is “unfamiliar”. Scientific analysis shows that the climate of the Caribbean region is already changing in ways that seem to signal the emergence of a new climate regime. Irma and Maria fit this pattern all too well. At no point in the historical records dating back to the late 1800s have two category five storms made landfall in the small Caribbean island chain of the eastern Antilles in a single year.

The intensification almost overnight from a tropical storm to a category five hurricane and the devastating intensity that lingered for several days are also unfamiliar, even to a region that is used to seeing hurricanes. Alongside other emerging climate patterns, there is a strong case to be made that there is something unfamiliar about the Caribbean’s climate today. We are seeing repeated and prolonged droughts, an increase in the number of very hot days, intense rainfall events causing repeated localised flooding, and rising sea levels that are consuming the beautiful beaches on which tourism in our region depends.

The problem with unfamiliarity is that daily existence in the Caribbean is built on familiar patterns of climate. ...

California wildfires ...
“Those northerly winds were fairly well forecasted,” Abatzoglou said. “We did see this coming, though people did not probably expect the breadth of fire activity.”

Though the winds are seasonal events and it’s difficult to attribute any individual spike to climate change, humanity’s fingerprints are all over the fuel for these fires.

Abatzoglou co-authored a study last year that found that climate change due to human activity accounted for roughly 55 percent of the aridity in Western US forests between 1979 and 2015.

This led to a doubling of the area torched by forest fires than would have occurred in the absence of human-caused factors.

This shows how the feds have intentionally or not given a boost to fossil fuels and diverted interest in renewables for years and years:
https://yro.slashdot.org/story/17/10/20 ... stallation
Every two years, the U.S. Energy Information Administration (EIA), America's official source for energy statistics, issues 10-year projections about how much solar, wind and conventional energy the future holds for the U.S. Every two years, since the mid-1990s, the EIA's projections turn out to be wrong. Last year, they proved spectacularly wrong. The Natural Resources Defense Council, an environmental advocacy group, and Statista recently teamed up to analyze the EIA's predictions for energy usage and production. They found that the EIA's 10-year estimates between 2006 to 2016 systematically understated the share of wind, solar and gas. Solar capacity, in particular, was a whopping 4,813% more in 2016 than the EIA had predicted in 2006 it would be. .............
