Marine Heatwaves – Trends, Impacts Attribution, and Software

For the week of 01 October 2018

Join us Tuesday, October 23, 2018 at 4 pm US EDT / 1 pm US PDT/8 pm UTC - Wednesday, October 24, 7 am Australian EST for a webinar on Marine Heatwaves – Trends, Impacts Attribution, and Software by Alistair Hobday of CSIRO and Eric Oliver of Dalhousie University.

Extreme climate and weather events shape the structure of biological systems and affect the biogeochemical functions and services they provide for society. There is overwhelming evidence that the frequency, duration, intensity and timing of extreme events on land are changing under global warming, increasing the risk of severe, pervasive and in some cases irreversible impacts on natural and socio-economic systems.  Climatic extremes also occur in the ocean, and recent decades have seen many high-impact marine heatwaves (MHWs) –anomalously warm water events that may last many months and extend over thousands of square kilometres. A range of biological and economic impacts have been associated with some intense MHWs. We will cover historical and projected trends in these events, and the role of attribution for communication and mechanistic understanding. Growing public interest in marine extreme events means that measuring the severity of these phenomena in real time is becoming more important, and we propose a method for consistent description of MHWs that is compatible with an underlying long term trend. Finally, we will demonstrate software that is available for use to study or follow MHWs in your area of interest.

Climate scientists are struggling to find the right words for very bad news

The duties of the IPCC include informing governments on climate change statistics and introducing global plans to limit more dire results. A main concern is atmospheric warming. The panel goal is to contain warming to at most 1.5 degrees Celsius or 2.7 degrees Fahrenheit. The outlook for reaching this goal is slim. The planet has already warmed 1 degree Celsius, leaving only .5 degrees left. In the newest report by the IPCC, the council pushes for change through the “Talanoa Dialogue,” where the countries under the Paris agreement now must discuss where and how they veered from their original goals in 2015 and how they plan to act to ensure the 1.5 degree goal is reached.

Rolling Back Regulations, and Arctic Sea Ice Keeps Melting

The New York Times, in this weekly column, detail the current news relating to our planet’s climate and climate change. In this issue, the column talks of the loosening of environmental policy within the U.S., the fall-out of government climate advisors, and the inevitable loss of Arctic Ice. Enjoy!

U.S. Supreme Court declines to take Martins Beach case — a win for California's landmark coastal access law

The final verdict for Martins Beach is a win for beach-goers. This long disputed case was brought into national attention when a Silicon Valley Billionaire refused to open his gate to allow for beach access. Claiming private property rights; local beach goers and NGOs fought his claim. However, this case was more than just about beach access rights. For many, it was a fight against unequal rights between the extremely wealthy and middle class America.  (via Los Angeles Times)

Commercial fishing banned across much of the Arctic

Nine nations, including Japan, Russia, and Norway, have signed an agreement in Greenland which bans any commercial fishing in a zone the size of the Mediterranean Sea within a newly opened portion of the Arctic. As climate change continues to warm oceanic waters and the air, the Arctic melts, opening pathways never before explored. This pact will last 16 years and is intended to help give time for international agreements to be made surrounding the Arctic. (via The Guardian)
