We are approaching the time in which 2012 ASI dropped 1.13 million km2 in 9 days (an average of 125.5K km2/day).

Trying to know what it happened, it is always a great source Neven's ASI Blog.

There are also some interesting stories on June 2012, like the fires on Siberia...

Hope things are better for you today, Juan  :-*

I excuse myself because I expressed myself so badly. Pollution has been terrible in central Mexico, but I was only taking about been out for one or maybe a couple of days. I was feeling pretty bad, so I was not going to post yesterday night.
Things are fine (as fine as it can be, given that we have lost almost 2/3 of ASI volume, measuring 2010-18 versus 1979-2000 and we have also local pollution). But I hope to be posting here for several years. I am JAXA addicted, so I usually cannot go to bed without looking the new data.

Thanks for been concerned and for your good wishes…  :)

"Trump administration pushed to strip mention of climate change from Arctic policy statement"
Quote
The Trump administration sought to remove references to climate change from an international statement on Arctic policy that Secretary of State Mike Pompeo is expected to endorse next week, leading to sometimes testy negotiations over how much to emphasize an issue considered a crisis for the region.

The Arctic Council declaration is an affirmation of goals and principles among the eight Arctic nations, which meet every two years. The Trump administration’s position, at least initially, threatened a standoff in which the United States would not sign onto a statement that included climate discussion and other members would not agree to a version that left it out, according to senior diplomats and others familiar with the discussions.

The administration objected to language that, while nonbinding, could be read as a collective commitment to address the effects of climate change in the Arctic, diplomats said. One official familiar with the preparations for this year’s meeting said that at meetings last month, the United States “indicated its resistance to any mention of climate change whatsoever.”

"NASA’s new carbon observatory is set for launch despite Trump’s efforts to ax it"
Quote
Trump slashed funding for the Orbiting Carbon Observatory 3 and four other Earth science missions in his proposed spending plan for the 2018 fiscal year, citing “budget constraints” and “higher priorities within Science.” His budget for fiscal year 2019 tried to defund them again.
In both cases, Congress decided to keep the OCO-3 mission going anyway. Now it is set to launch as soon as Tuesday.

How is OCO-3 different than OCO-2?
The main purpose of OCO-3 is to make sure we have a continuous record of carbon dioxide levels in the atmosphere, but we are adding some new capabilities. One of those is to take a snapshot of carbon levels over an area of 50 miles by 50 miles. This will feed a bunch of science investigations of emission hot spots, like cities or volcanoes.
We can also look at how plant activity changes over the course of a day, which is something OCO-2 could not do.

Yes, but that third dimension, thickness, is several orders of magnitude smaller than the other two.  Hence, the third dimension forces have much less influence on the total makeup than the other two.

If this third dimension "is several orders of magnitude smaller than the other two", could be the first one in disappearing. But if this dimension disappears: ¿what will happen to the other two?

Arctic sea ice / Re: The 2019 melting season
« on: March 31, 2019, 07:38:52 AM »
I have a vague recollection of someone (a year or two ago) comparing early ice melt with season-complete ice melt and found no correlation.  Can someone with data run a comparison and enlighten us?

(It's the 'only' hope we have of my 2013 projection of ice freedom in 2019 not coming to pass.)
There were some comments about this on NSIDC Analysis.

By memory, the lowest years on September are 2005-2007, 2010-2012 and 2015-2018. Looking at the ice on March on those years, the great exemption is 2012, that had more ice than 2010's average on March and end up being the lowest on September (and by far). But all the other years that were low on September, they were also low on March.
So, I don't think that low values on March will mean that we will not have a low record on September. If we have melting conditions on June-August, 2019 will be terrible.
2019 is going to make me eat my nails, with the -165,712 km2 drop that we have today and the heat that we still have on the Arctic.

P.S.: I didn't include 2010 on the graph and it is close to 2012 on March. So there is another year that it was above average on March and end up with a low value on September.

In blow to climate, coal plants emitted more than ever in 2018
Quote
Energy demand around the world grew by 2.3 percent over the past year, marking the most rapid increase in a decade, according to the report from the International Energy Agency. To meet that demand, largely fueled by a booming economy, countries turned to an array of sources, including renewables.
But nothing filled the void quite like fossil fuels, which satisfied nearly 70 percent of the skyrocketing electricity demand, according to the agency, which analyzes energy trends on behalf of 30 member countries, including the United States.
In particular, a fleet of relatively young coal plants located in Asia, with decades to go on their lifetimes, led the way toward a new record for emissions from coal fired power plants — exceeding 10 billion tons of carbon dioxide “for the first time," the agency said. In Asia, “average plants are only 12 years old, decades younger than their average economic lifetime of around 40 years,” the agency found.

Federal judge casts doubt on Trump’s drilling plans across the U.S. because they ignore climate change

Quote
The decision by U.S. District Court for the District of Columbia Judge Rudolph Contreras marks the first time the Trump administration has been held to account for the climate impact of its energy-dominance agenda, and it could have sweeping implications for the president’s plan to boost fossil fuel production across the country. Contreras concluded that Interior’s Bureau of Land Management “did not sufficiently consider climate change” when making decisions to auction off federal land in Wyoming to oil and gas drilling. The judge temporarily blocked drilling on roughly 300,000 acres of land in the state.

Arctic sea ice / Re: 2019 sea ice area and extent data
« on: March 19, 2019, 01:50:44 AM »
JAXA max extent on March 12th, with an extent on 14,271,121 km^2. This requires a daily extent loss of -72,520 km^2 for 183 straight days (on average) for a blue ocean event to occur.
I like your comment, but the truth, I discard a blue ocean event (BOE) on the near future.

I think that we are on a new stage, in which it will be bad enough if on the following 12 years (2030):
   a) We have 3 years like 2012 or a little worst.
   b) We have an increase in the annual average sea level rise.
   c) We have an increase in methane emissions, because of permafrost melting.

I think that we have a big probability of seeing these three events on the following 12 years, no matter what we do.

Juan & Ger thanks for reporting on this winter season.
I'll join the public thanking ceremony. JCG's and Ger's area/extent posts are the ones I first read whenever I get the chance.
Thanks everyone! It really felt like a public thanking ceremony!   ;)
