Horrific Air Pollution in Europe Reaches 7 cigarettes per day equivalent, a pack a day in India and China It’s winter, and that’s the worst air pollution period for Europe and China. The levels over much of the continent are in the unhealthy range. In the figure we show a map of the pollution of […]
2016 was the warmest year since humans began keeping records, by a wide margin. Global average temperatures were extremely hot in the first few months of the year, pushed up by a large El Nino event. Global surface temperatures dropped in the second half of 2016, yet still show a continuation of global warming. The […]
by Zeke Hausfather Air pollution in China is a critical global health problem, responsible for somewhere between 700,000 and 2.2 million premature deaths annually. The largest single contributor to air pollution-related mortality is particulate matter below 2.5 microns in size, or PM2.5. Exposure to PM2.5 has been found to increase the risk of heart attacks, […]
by: Zeke Hausfather, Berkeley Earth zeke@berkeleyearth.org The relationship between greenhouse gas (GHG) emissions and future warming is complex, depending on the atmospheric lifetime of gases, their radiative forcing, and the thermal inertia of the Earth, particularly our oceans. Many non-CO2 GHGs have shorter atmospheric lifetimes, and the global warming-equivalent values commonly used for analysis of emission […]
By Zeke Hausfather In recent weeks we’ve seen a political controversy over NOAA’s adjustments to temperature records, with accusations from some in congress that records are being changed to eliminate a recent slowdown in warming and to lend support to Obama administration climate policies. This makes it sound like the NOAA record is something of […]
Can natural gas help us reduce climate change by acting as a bridge fuel away from coal? New research from Berkeley suggests that it can, even if it modestly delays the date at which we switch to renewables. The U.S. is in the midst of a natural gas boom. The combination of horizontal drilling and […]
