35 years of climate change in one video

By Johnny Wood 18 November 2019 (WEF) – Q: If you subtract 95 percent from something, what’s left? A: An environmental crisis. The “something” in question is the oldest and thickest solid layer of frozen water in the Arctic Ocean, which is melting so rapidly that just 5% of its original mass remains. Scientists from the […]

GHG emissions in GtCO2e materials production by material and by the first use of materials. In 2015, the production of materials caused GHG emissions of approximately 11.5 GtCO2e, up from 5 GtCO2e in 1995. The largest contribution stems from bulk materials production, such as iron and steel, cement, lime and plaster, other minerals mostly used as construction products, as well as plastics and rubber. Two thirds of the materials are used to make capital goods, with buildings and vehicles among the most important. While the production of materials consumed in industrialized countries remained within the range of 2–3 GtCO2e, in the 1995–2015 period, those of developing and emerging economies have largely been behind the growth. In this context, it is important to keep in mind the discussion about the point of production and points of consumption. Graphic: UNEP

World must cut carbon emissions by 7.6 percent every year for next decade to meet 1.5°C Paris target – “It is very disturbing that in spite of the many warnings, global emissions have continued to increase and do not seem to be likely to peak anytime soon”

GENEVA, 26 November 2019 (UNEP) – On the eve of a year in which nations are due to strengthen their Paris climate pledges, a new UN Environment Programme (UNEP) report warns that unless global greenhouse gas emissions fall by 7.6 per cent each year between 2020 and 2030, the world will miss the opportunity to […]

“Climategate” 10 years on: what lessons have we learned? “British climate science was subjected to huge scrutiny by the world’s best journalists and it stood up to the test”

By Robin McKie 9 November 2019 (The Guardian) – The email that appeared on Phil Jones’s computer screen in November 2009 was succinct. “Just a quick note to encourage you to shoot yourself in the head,” it said. “Don’t waste any more time. Do it today. It is truly the greatest contribution to mankind that […]

Greenhouse gas concentrations in atmosphere reached yet another high in 2018

GENEVA, 25 November 2019 (WMO) – Levels of heat-trapping greenhouse gases in the atmosphere have reached another new record high, according to the World Meteorological Organization. This continuing long-term trend means that future generations will be confronted with increasingly severe impacts of climate change, including rising temperatures, more extreme weather, water stress, sea level rise […]

The city is thought to have been founded by refugees seeking protection from Germanic invaders by sheltering in the northwestern Adriatic Sea’s islands and marshes. By the 12th century, the doge would annually […]

Radar plots of urban types based on identified factors. For each city we collect information on 64 urban indicators, from which we identify nine dominant factors: metro, bus rapid transit (BRT), bikeshare, development, population, sustainability, congestion, sprawl, and network density (Oke, et al. 2018). We then cluster the 331 cities on these nine factors, producing 12 unique city types Radar plots indicate normalized factor scores (from 0 to 1) averaged for all cities in each type; adapted from Oke, et al. (2018). The “Congested Boomer” type represents rapidly growing megacities with severe congestion problems and low metro availability, particularly in India; notable members are Bangalore, Mumbai, and Delhi.

Why the electric-car revolution may take a lot longer than expected – MIT analysis finds steady declines in battery costs will stall soon

By James Temple 19 November 2019 (Technology Review) – A new report from the MIT Energy Initiative warns that EVs may never reach the same sticker price so long as they rely on lithium-ion batteries, the energy storage technology that powers most of today’s consumer electronics. In fact, it’s likely to take another decade just to eliminate […]
