on 02024-11-28“The increase in [CO₂] emissions in the [electric] power sector was offset by falling emissions from #steel, #cement and oil use, plus stagnating gas demand outside the power sector, meaning #China’s CO2 output in the third quarter was flat or slightly declined, relative to a year earlier.” Apparently they’ve been declining since February. #climate-change
on 02024-11-28#China is switching from limiting #energy usage to limiting CO₂ emissions to mitigate #climate-change, as of August 2. “The output of the cement and steel industries has also been declining due to the slump in the real estate sector, suggesting that China’s CO2 emissions may have peaked in the first quarter of this year and showed a downward trend in the second quarter. However, the current trend is not sufficient to achieve the 18% target, and China needs to accelerate the development of clean energy while reducing the use of fossil fuels in the power sector and other industries.” The cement industry thing might explain why China can be importing more #coal than ever but emitting less CO₂.

The WEO’s figure for 02020 is 103 GW, nothing like the 196 GW you'd expect if the exponential trend had continued. #CC by-nc-nd #climate-change #energy #pricing #history

on 02017-07-11MODIS (36-band, infrared, 250m resolution) data is available, but old #datasets are being “decommissioned”: “The Level-1 and Atmosphere Archive and Distribution System (LAADS) Distributed Active Archive Center (DAAC) plans to decommission the following Terra and Aqua MODIS product collections on June 30, 2017. Starting on July 1, 2017, users interested in accessing and acquiring Collection-5 (C5) decommissioned land products may do so from the Land Processes DAAC. Users will have no recourse to access the C5.1 MODIS atmosphere collections starting August 1, 2017, and are advised to use the C6 collection. Users will have no recourse to access the C5 MODIS L1 products starting January 1, 2018, and are advised to use the C6 MODIS L1 collection.” Not sure if this has to do with #Trump #politics trying to cover up #climate-change.

In fact, I’m not sure the whole thing isn’t crazy, this climate change. You’ve only got to look at Singapore. It’s two-and-a-half times higher than the worst-case scenario for climate change, and it’s one of the most desirable cities in the world to live in.”
