Ecosystems the size of Amazon rainforest “can collapse within decades”

By Jonathan Watts 10 March 2020 (The Guardian) – Even large ecosystems the size of the Amazon rainforest can collapse in a few decades, according to a study that shows bigger biomes break up relatively faster than small ones. The research reveals that once a tipping point has been passed, breakdowns do not occur gradually […]

Carbon emissions (CO2e) from different modes of transportation. Non-pooled ride hailing, like with Uber and lyft, emits the most carbon, by a wide margin. Graphic: UCS

Taking an Uber or Lyft pollutes more than driving, California finds – “For a one-mile trip, on average there’s another 0.7 miles of driving around to deliver that trip”

By Tony Barboza 7 March 2020 (Los Angeles Times) – Behind the tap-of-your-phone convenience of hailing an Uber or Lyft lies an inconvenient truth: Such rides generate more carbon emissions than simply driving yourself. The increased pollution comes primarily from “deadheading,” that is, drivers traveling to pick up a passenger or cruising the streets while […]

Spring 2020 in southern U.S. arrives earlier than ever recorded, adding to climate trend

By Cassidy Randall 6 March 2020 (The Guardian) – Across the south-eastern US, trees are unfurling their clouds of leaves after winter. Yet this picturesque and usually welcome development is this year cause for consternation. New data from the USA National Phenology Network (USA-NPN) shows that in parts of North Carolina, South Carolina and northern Florida, […]

Sandstorm wreaks havoc in Canary Islands, worst such storm to hit the islands in 40 years – “I’m old enough to know all about the calima, but I don’t recall it that strong. Everything just turned red.”

By Raphael Minder 24 February 2020 MADRID – Winds from the Sahara continued to send streams of sand drifting over the Canary Islands on Monday, creating chaos as the swirling sands forced planes to be grounded, disrupted traffic and exacerbated wildfires. Ángel Víctor Torres, the regional president of the islands, a Spanish archipelago, told Spanish […]

Flooding alerts are still in place, and this weekend could bring more wet weather with heavy wind also expected. This will be the fifth weekend in a […]

Observational and modeled climatology (contours) and trends (shading) of the zonal component of the near ocean surface wind. (a) Ensemble trends of the zonal near ocean surface wind based on the NCEP/NCAR, NCEP/DOE and NERA‐Interim reanalysis data sets covering 1979–2018. Stippling indicates regions where the trends pass the 95 percent confidence level (Student's t test). (b) Zonal near ocean surface wind change in the doubled CO2 simulations relative to the pre‐industrial control simulation carried out by AWI‐CM. Stippling indicates areas where the magnitude of the trend is larger than the standard deviation of the local variability. The subpanel at the right side of each graph shows the zonally averaged climatology (blue) and trend (red) of zonal near ocean surface wind.

Major wind-driven ocean currents are shifting toward the poles – “Over the past 40 years, all eight wind-driven surface current systems had shifted poleward”

24 February 2020 (AWI) – In the course of the past 40 years, the major wind-driven current systems in the ocean have steadily shifted toward the poles. Experts at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), came to this conclusion after analysing long-term global satellite data on the ocean surface […]

The boreal winter season 19/20 was by far the warmest winter season ever recorded in Europe – “Europe has been experiencing its mildest winter on record”

4 March 2020 (C3S) – With persistent mild weather over Europe, particularly in the north and east, the past winter was 3.4 °C warmer than the average winter for the period 1981-2010. The temperature was almost 1.4°C higher than that of the previous warmest winter, 2015/16. Back in November C3S seasonal predictions provided strong indications […]
