Large cities may cut emissions by a third based on improvements in housing density alone. Reducing driving is essential

Patrick Sisson at Curbed pointed out recently that some studies have estimated that large global cities could cut their emissions by a third based on improvements in housing density alone. We have to start talking about these solutions and making them part of mainstream environmental policy, Hankins says. Time is running out. “We can’t afford to ignore significant climate mitigation measures just …

Honolulu, NYC lead clean energy resilience plans

Katie Pyzyk@_PyintheSky Jan. 31, 2020, Smart Cities Dive Honolulu and New York City are top-scoring U.S. cities for incorporating energy efficiency and renewable power policies into resilience plans, according to a study from the American Council for an Energy-Efficient Economy (ACEEE). They ranked “exemplary,” while Atlanta, Chicago and Washington, DC followed close behind. The study concluded that many cities are taking steps toward …

US leads in per capita and total emissions. It’s time to shut off fossil fuel development.

Such concerns led Philip Alston, the UN special rapporteur on extreme poverty and human rights, to declare that climate change is “an unconscionable assault on the poor” in a report to the Human …

The remaining carbon budget

The estimate of global warming up to the present day; The assumed future warming from emissions of non-CO2 forcings such as methane and black carbon and the reduction of cooling sulphate emissions; The amount of warming still in the pipeline once emissions are brought back to zero; The ratio between cumulative CO2 emissions and global warming (also known as the …

CO2 hits over 415 ppm

The concentration of carbon dioxide, the main, long-lived greenhouse gas causing global climate change, in Earth’s atmosphere has reached new heights, according to scientists at Scripps Institution of Oceanography. Why it matters: The new reading of 415.26 parts per million (ppm) on May 11 was the first daily baseline at Hawaii’s Mauna Loa Observatory to eclipse 415 ppm. That observatory has …

NYC can expect a Hurricane Sandy-like flood every 5 years if we turn around fossil fuel use now (1.5 C) or three per decade if temps rise around 2 C

The study found that New York City can expect two Hurricane Sandy-like floods per decade by the year 2100 if global temperatures rise 1.5 degrees Celsius above pre-industrial levels, and three such events per decade if temperatures rise to 2.0 and 2.5 C. Credit: DJ Rasmussen, Princeton University The 2015 Paris climate agreement sought to stabilize global temperatures by limiting …

“Being the Change”: daily practices of a happy, good community

In his new book, NASA climate scientist Peter Kalmus explores the daily practices that build healthy, happy, and resilient communities. Peter Kalmus posted Jan 09, 2018 It can be hard to find hope in climate change mitigation. But that’s exactly what NASA climate scientist Peter Kalmus does in Being the Change. While he’s not your typical government scientist—he commutes by bicycle, …
