2nd Strongest Storm in Arabian Sea History: Extraordinary Chapala Hits 155 mph

Chapala topped out for the time being as a top-end Category 4 storm with 155 mph winds (1-minute average) at 2 am EDT Friday, according to the Joint Typhoon Warning Center (JTWC). Indonesia’s huge fires might be the worst climate change crisis on Earth right now.

Indonesia’s huge fires might be the worst climate change crisis on Earth right now

On Monday afternoon, Indonesian President Joko Widodo cut short a visit to the United States and headed home to oversee efforts to extinguish a rash of epic wildfires that have engulfed his country. Joko was in Washington, D.C., for a photo op with President Barack Obama, to talk about climate change, and to promote Indonesia as a choice venue for foreign investors. His trip was also supposed to include a stopover in San Francisco for meetings with tech industry executives. But Joko’s decision to return to Indonesia early underscores the challenges his country faces in stopping the worst deforestation on Earth — deforestation that is playing a critical role in global climate change.

Fossil fuel companies aren’t just bad for the climate — they’re bad investments. Activists often use moral language when advocating for divestment from fossil fuel companies: It is wrong to participate in the destruction of our planet, say college students and the parishioners of liberal churches.

Fossil fuel companies aren’t just bad for the climate — they’re bad investments

We should express our disapproval by divesting, they argue, and help to build momentum for carbon regulation and cleaner energy sources. But what if fossil fuels are just bad investments? What if oil, gas, and coal companies have sunk billions of dollars into buying up the rights to carbon fuels that they will never actually be able to extract? Indonesia is burning. So why is the world looking away?

I’ve often wondered how the media would respond when eco-apocalypse struck.

Indonesia is burning. So why is the world looking away?

I pictured the news programmes producing brief, sensational reports, while failing to explain why it was happening or how it might be stopped. Then they would ask their financial correspondents how the disaster affected share prices, before turning to the sport. This Could Be the Worst Climate Crisis in the World Right Now.

Ancient Permafrost Quickly Transforms to Carbon Dioxide upon Thaw (10/26/2015 3:00:00 PM)

Geological Survey and key academic partners have quantified how rapidly ancient permafrost decomposes upon thawing and how much carbon dioxide is produced in the process. Huge stores of organic carbon in permafrost soils ­­— frozen for hundreds to tens of thousands of years across high northern latitudes worldwide — are currently isolated from the modern day carbon cycle. However, if thawed by changing climate conditions, wildfire, or other disturbances, this massive carbon reservoir could decompose and be emitted as the greenhouse gases carbon dioxide and methane, or be carried as dissolved organic carbon to streams and rivers. Ancient low–molecular-weight organic acids in permafrost fuel rapid carbon dioxide production upon thaw.

Ancient low–molecular-weight organic acids in permafrost fuel rapid carbon dioxide production upon thaw

Cole, Cary Institute of Ecosystem Studies, Avon, NC, and approved September 28, 2015 (received for review June 16, 2015) Significance To our knowledge, this study is the first to directly link rapid microbial consumption of ancient permafrost-derived dissolved organic carbon (DOC) to CO2 production using a novel bioreactor. Rapid mineralization of the freshly thawed DOC was attributed to microbial decomposition of low–molecular-weight organic acids, which were completely consumed during the experiments. Abstract Northern permafrost soils store a vast reservoir of carbon, nearly twice that of the present atmosphere.

Autant de mesures à l’efficacité douteuse et aux effets secondaires imprévisibles – les risques de la mort-aux-rats pour les autres animaux, l’impact des clôtures sur la survie d’espèces déjà menacées, la destruction de l’économie nomade tibétaine ou encore le déclenchement forcé des pluies dans une région au climat des plus extrêmes. Ces traitements adoptés à la va-vite par les officiels, sans réel débat, peuvent ajouter aux déséquilibres plutôt que d’y remédier : « Ces réponses ne reposent que sur une compréhension très superficielle de la chaîne de problèmes », s’inquiète M.

Pour le professeur Jean-François Toussaint, membre du Haut Conseil de la santé publique, qui travaille notamment sur les questions d'adaptation au changement climatique, et est interrogé dans ce rapport, pas de doute le changement climatique va provoquer de nouveaux problèmes de santé, y compris sous nos latitudes où des maladies liées au climat apparaissent, comme la dengue et le chikungunya. "Il faut qu'on les surveille pour comprendre et anticiper très rapidement ce que pourraient être les effets d'autres épidémies, d'autres virus émergents" explique le professeur Jean-François Toussaint.

The industrial food system accounts for approximately 30-50% of total greenhouse gas (GHG) emissions.

Antarctic Ice Shelves Face Major Threat If CO2 Emissions Keep Rising. Marine Food Chains at Risk of Collapse,  Study of World’s Oceans Finds. By The Guardian – October 13, 2015 Important ecosystems could be massively damaged by 2050 unless greenhouse gas emissions and localized pollution is drastically reduced, researchers say By Oliver Milman The food chains of the world’s oceans are at risk of collapse due to the release of greenhouse gases, overfishing and localized pollution, a stark new analysis shows. A study of 632 published experiments of the world’s oceans, from tropical to arctic waters, spanning coral reefs and the open seas, found that climate change is whittling away the diversity and abundance of marine species. photo by SarahDepper, on FlickrStaghorn Coral (with evidence of coral bleaching) The paper, published in the Proceedings of the National Academy of Sciences, found there was “limited scope” for animals to deal with warming waters and acidification, with very few species escaping the negative impact of increasing carbon dioxide dissolution in the oceans.

Hot Oceans Are Killing Coral Reefs Around the World. For the past year, the world’s corals have been getting increasingly pummeled by climate change. Now with El Niño kicking ocean heat into overdrive, much of the world’s oceans have turned deadly for the world’s corals. On Thursday, the National Oceanic and Atmospheric Administration (NOAA) announced a global coral bleaching event. This year joins the ranks of 1997 and 2010 as the only times on record that bleaching has occurred in all three of the world’s oceans that support coral at the same time. Carbon choices determine US cities committed to futures below sea level. Author Affiliations Edited by James Hansen, Columbia University, New York, NY, and approved September 18, 2015 (received for review June 8, 2015) Significance As greenhouse gas emissions continue to rise, the window to limit global warming below 2 °C appears to be closing.

Associated projections for sea-level rise generally range near or below 1 m by 2100. However, paleontological and modeling evidence indicates long-term sea-level sensitivity to warming that is roughly an order of magnitude higher.

New finding shows climate change can happen in a geological instant. (Phys.org) —"Rapid" and "instantaneous" are words geologists don't use very often. But Rutgers geologists use these exact terms to describe a climate shift that occurred 55 million years ago. In a new paper in the Proceedings of the National Academy of Sciences, Morgan Schaller and James Wright contend that following a doubling in carbon dioxide levels, the surface of the ocean turned acidic over a period of weeks or months and global temperatures rose by 5 degrees centigrade – all in the space of about 13 years.
