Excerpts;

Last year was the hottest ever measured, continuing an upward trend that is a direct result of manmade greenhouse gas emissions.

The key to the measurements is the oceans. Oceans absorb more than 90% of the heat that results from greenhouse gases, so if you want to measure global warming you really have to measure ocean warming…

To Hold Warming to 1.5 Degrees, Study Says Nations Must Stop Building New Fossil Fuel Infrastructure Immediately; Yale E360 (01-15-2019)
If nations commit immediately not to replace fossil fuel infrastructure as it reaches the end of its expected lifetime, the world would have a 64 percent chance of keeping global warming below 1.5 degrees Celsius, according to a new study…

Climate change tipping point could be coming sooner than we think; Science Daily (01-23-2019)
A new study confirms the urgency to tackle climate change. While it’s known that extreme weather events can affect the year-to-year variability in carbon uptake. this study is the first to actually quantify the effects through the 21st century…

Excerpts;

When America’s fleet of nuclear reactors was designed some four-plus decades ago, few people had ever heard the phrase “climate change.” Today, the global threats of worsening weather patterns and natural disasters are well recognized, commanding concern and responses across the board. Except, apparently, at the U.S. Nuclear Regulatory Commission…

Excerpts;

Between 2014 and 2016, parts of the eastern Pacific Ocean warmed as much as 7 degrees Fahrenheit above average during what has been characterized as the worst marine heatwave on record. During the event, scientists began discovering a record number of tropical sea species along the northern California and Oregon coasts, more than 700 miles north of their usual range…

Fatal horizon, driven by acidification, closes in on marine organisms in Southern Ocean

Excerpts;

Marine microorganisms in the Southern Ocean may find themselves in a deadly vise grip by century’s end as ocean acidification creates a shallower horizon for life.

The modeling study, published today in the journal Nature Climate Change, forecasts that at current carbon dioxide emission rates, the depth at which some shelled organisms can survive will shrink from an average of 1,000 meters today to just 83 meters by the year 2100, a drastic reduction in viable habitat.

The steep drop, which could happen suddenly over a period as short as one year in localized areas, could impact marine food webs significantly and lead to cascading changes across ocean ecosystems, including disruptions of vital global fisheries…

Coastal waters are unexpected hotspots for nitrogen fixation


Photograph: © SAF — Coastal Care

Excerpts;

Nitrogen fixation is surprisingly high in the ocean’s coastal waters and may play a larger role than expected in carbon dioxide uptake, a new study shows.

The findings — based on thousands of samples collected in the western North Atlantic — upend prevailing theories about where and when nitrogen fixation occurs, and underscore the need for scientists to revisit the global distribution of marine nitrogen fixation and reevaluate its role in the coastal carbon cycle…
