During the 1970s and 1980s, a US spy programme - codenamed Hexagon - launched 20 satellites into orbit to secretly photograph the Earth.

The covert images were taken on rolls of film that were then dropped by the satellites into the atmosphere to be collected mid-air by passing military planes.

The material was declassified in 2011, and has been digitised by the US Geological Survey for scientists to use.

This study shows that since 2000, glaciers heights have been shrinking by an average of 0.5m per year.

The group found that between 1975 and 2000, an average of 4 billion tonnes of ice was being lost each year.

But between 2000 and 2016, the glaciers melted approximately twice as fast - losing about 8 billion tonnes of ice each year on average, enough to fill 3.2 million Olympic-sized swimming pools per year.

Acceleration of ice loss across the Himalayas over the past 40 years

Science Advances

Here, we quantify changes in ice thickness during the intervals 1975–2000 and 2000–2016 across the Himalayas, using a set of digital elevation models starting at recently declassified cold war–era spy satellite film.

We observe consistent ice loss along 2000-km.

We find a doubling of the average loss rate during 2000–2016 compared to 1975–2000

The similar magnitude and acceleration of ice loss across the Himalayas suggests a regionally coherent climate forcing, consistent with atmospheric warming and associated energy fluxes as the dominant drivers of glacier change.

Thanks, I'll digest this later, but probably related is the news that Chennai has a severe water shortage. You would expect that as ice retreats in the Himilayas, and that the snow cap slowly rises in altitude, that the aquifers got to a point where the slowly increasing demand has quietly rolled past the slowly decreasing topup

I applaud Trump for his work on emission standards. Reducing them to lower, then lower than gutter level has been achieved. 

 

IF his Marketing 101/Stupid Americans get him re elected, the rest of us, as in first world countries need to revolt. This is beyond stupid.

Doesn't matter who or how many people or countries tell him.  If it differs from what he "believes" then it is clearly lies.

 

That's the problem with being stupid, you don't know that you are.

Perhaps this thread should be confined to NZ issues ...there is a Trump thread on the "political" forum.

There is a post on neighbourly about acquiring and installing a diesel home heating system. The replies were very informative, but not one about why don't you use something that is no or low emissions?  So I did, but its a small sample of disintrest

Here's a recent article (27 June 2019) about NZ's increasing household emissions:

 

Short extract from above:

 

Stats NZ says household emissions increased by 19.3 percent between 2007 and 2017, mainly due to rising emissions from road transport.

 

On Thursday, the official data agency said New Zealand households are becoming less efficient at managing the emissions they produce.

 

Massey University sustainable energy and climate mitigation Professor Emeritus Ralph Sims said the findings were "deeply concerning" and New Zealand had a major problem.

 

"The pending climate change legislation (now long overdue) will be essential to start to bring our emissions down but it will need strong regulations urgently imposed to make a difference in the short term," he said in a statement. "And time is running out."

 

It's worth reading the full article and noting the views of Professor Sims.

If someone could invent a machine that reduced greenhouse gases powered by politicians' jaw movements, we'd be back to pre-industrial CO2 levels.

If you own a Keurig coffee maker, you're probably a bit of a dick. In the past, those plastic k-cups were just contanimating the recycling stream, wrong kind of plastic plus foil tops, or going straight to the landfill.

https://www.usatoday.com/story/tech/2019/03/13/heres-why-your-used-k-cups-coffee-pods-arent-usually-recycled/3067283002/

K-cups and coffee capsules: Is your quick java fix killing the environment?

by Dalvin Brown, USA TODAY

Like many Americans, 29-year-old Tiffany Mooney uses a single-serving beverage brewing system to produce her daily cup of coffee.

She loads the at-home brewer in the morning with a pint-sized plastic coffee capsule and within minutes her hot drink is ready. Around lunchtime, she pops in a plastic-encased Cappuccino-flavored brew to keep her going.

And right before bed, the Hanceville, Alabama, resident opts for a "relaxing" hot chocolate flavor.

"That thing is my life," Mooney said about her Walmart-brand coffee maker. "But I know that tossing the empty little cups in the garbage after I use them isn't the most environmentally friendly thing to do."

She's right.

They’re small, convenient and filled with every flavor imaginable.

For some, they’re pricey to buy. Others purchase them in bulk by the dozen. Regardless of how or where you buy the 2-by-2-inch pods, these modern-day coffee containers increasingly contribute to the mountain of plastic that's ending up in landfills.

To put it mildly, "Coffee pods are one of the best examples of unnecessary single-use plastics that are polluting our planet," said John Hocevar, the campaign director of Greenpeace USA, an environmental nonprofit organization. "Many end up getting incinerated, dumping poison into our air, water and our soil."

Coffee pods can wind up in rivers where they wash into lakes and oceans. Over time, the plastic breaks down into smaller pieces that choke and kill wildlife, Hocevar said.

Whether K-Cups, or Nespresso Capsules, or other brands, coffee pods are generally small plastic or aluminum containers with aluminum foil lids that can create one cup of coffee with the press of a button. Despite being substantially more expensive per pound than regular coffee brewed in a pot, they’ve been the go-to solution for caffeine addicts who need a quick fix since the '90s.

But the big boom happened around 2012, according to the National Coffee Association (NCA). In 2012, about 10 percent of coffee consumers brewed using this method, and the percentage increased each year since.

By 2018, the number of users more than doubled. Today, 41 percent of Americans own a single-cup coffee maker, according to NCA and Statista, a market research firm.

Front and center at supermarkets, drugstores and select dollar chains nationwide, popular brands include Keurig Green Mountain, Starbucks, Folger Coffee Co. and Kraft Heinz Co.

Keurig, Inc. launched its K-Cups for the home in 2004, after growing popularity in the office market. Within 10 years, enough K-Cups were sold that if placed end-to-end, they would circle the globe 10 times, Hocevar said.

My wife and I agreed a few years ago we should do what we can as we can. So far, we switched out the larger petrol car for a 998cc VW UP! that is much more fuel efficient than the old car. We also bought an electric car and we use that for most of our driving unless we have to be in different places. The EV is probably our largest single emissions reducing action. We paid more than we had ever paid for a car before......by 300%. But it has been hugely worth it because the EV is so cheap and reliable. I also try to use the train when its convenient as we live very near a train station (itself a deliberate choice). We had most of the gas appliances in the house deleted.

Moving along, we have bought a sunny house in a town outside Auckland and we will soon be installing solar panels and battery storage there. I'll shortly be ordering a Tesla Model 3 and selling my 30kWh LEAF to someone who needs it.  The idea is to not burn anything and not cause anyone else to burn anything. We're almost there.

There are local climate change deniers....and do-nothings (adds up to the same thing). We should reference those if we need to.

Chennai is far from the Himalayan watershed. Anyone along the Ganges will be affected, certainly, but Andra Pradesh and Chennai are too far south. They will suffer from the failure of the monsoons.
