If we are lucky, we may catch a glimpse of wildlife and incorporate the sighting into our memory of that place. When everyone takes action, we can keep our ocean clean.

Warming temperatures may be causing tundra ponds to evaporate or drain into thawing permafrost.

Special Report: Climate Change – Scientific American

The European Commission is targeting specific plastic products that constitute 70 percent of the items found among marine debris lost in the sea and along the shoreline. Warming could exact a major economic toll, but reducing emissions and adapting to changes can alleviate those costs December 3, — Andrea Thompson. Changes in phytoplankton growth, and nutrients, could affect famous mirror-like clarity. The panel of 2, scientists and other experts declared manmade warming “unequivocal” and wrote that it could lead to climate changes that are “abrupt and irreversible.

The Arctic climate is shattering record after record, altering weather worldwide. Manufacturers of plastic products would help fund those various programs, according to the proposal. I hope everyone takes a little time to consider whether a favorite photograph deserves special recognition. Taking on the enormous problem of plastic pollution in the ocean, the European Union is on track to ban single-use items made of plastic, while communities in Washington state slowly adopt bans on plastic bags.

Temperatures haven’t been that high since the Miocene warming period. December 13, — Christopher Intagliata.

For the first time, the commercial guidelines include time limits for watching any group of whales. These ranged from greater reliance on subnational government action to a sharp pivot to wind and solar energy and electric cars.


California Representative-elect, Mike Levin, thinks climate can rally voters in the next presidential race. State of the Science: Now I realize that our vanishing bull kelp has been vastly undervalued. But the more carbon that is emitted, the more carbon extraction will be needed in the form of reforestation, sequestration and technologies.

In addition, plans are underway for new waste-disposal programs, ongoing cleanups, and educational efforts designed to reduce the purchase of and encourage the proper disposal of food containers, plastic wrappers, cigarette butts, wet wipes, balloons and fishing gear. Motivated by events warning Hurricane Harvey, researchers are trying to determine how climate change interacts with agriculture, energy, transportation and other human systems.

A Century of Global Warming, in Just 35 Seconds

Twitter links powered by Tweet This v1. That low-probability but very extreme scenario could expose most of the world’s people to deadly heat stress, with 2. The movement, which seems to encourage people to go out in search of natural springs, grew rapidly in California with the help of a guru-like character who changed his name from Chris Sanborn to Mukhande Singh.

A clean energy think tank has proposed ways to make industry and shipping cleaner with existing technologies. The uptick follows several years of relatively flat emissions, underscoring the urgency of climate action. Awrming heat waves, drought and heavy rains in all bore the fingerprints of climate change. It does a body good — mentally and physically — to go into new or familiar surroundings while basking in the full-bodied sights and sounds of a forest, a stream or a marine shoreline.

More about that in a moment. They say warmjng dioxide might have to be removed from the atmosphere. The long-term goal of the Paris accord was to maintain warming well below 2 C.

The competition is organized by The SeaDoc Society. Turn Xmas Tree Into Food and Medicine Pine needles can easily be broken down into sugars, as well as the building blocks of paint, adhesives and medicines. Raw water, by definition, is left untreated and reported to contain living organisms that provide health benefits.

Some argue for a fund for future clean technology while others prefer to focus on reducing pollution from present sources.

That’s the finding of a pair of related reports released yesterday by an international group of climate science and policy luminaries who warned that the window is closing to avert dangerous warming. The goal is to reduce fishery removals of 25 to 35 percent, but details have yet warjing be released. While scuba diving years ago, I came to understand that kelp harbored a vast variety of fish, crabs and other warmihg.


I never fully appreciated the value of kelp until I began writing about the complexity of the Puget Sound ecosystem. While contract issues remain in dispute, the environmental benefits are clear, according to Joleen Palmer of the nearby Stillwaters Environmental Center.

Still, mostly out of fear of becoming entangled in kelp, I never ventured into the middle of a kelp forest. Warmer temperatures and rising CO2 can also ramp up some fungal toxins and allergens. Pine needles can easily be broken down into sugars, as well as the building blocks of paint, adhesives and medicines. This special report explores the latest findings on the impact of human activity on Earth’s climate—from the melting of Arctic ice to the potential spread of disease.

I will never know what I might have seen as a diver in the middle of warminh dense kelp forest, but I have always understood that kelp was generally a good thing. The science is clear that the earth is heating up and will continue to do so—with potentially catastrophic consequences—unless we change our ways.

Sea ice is the thinnest it’s been at any time in the last 30 years, and wild reindeer and caribou populations continue to decline.

How can we cope with global warming and the challenges it poses? Peter has published more than scciam papers in scientific journals. Search Puget Sound Blogs. Jean Chemnick Recent Articles U. I cannot conceive of the ecological loss of a single kelp bed, let alone the dozens g,obal kelp forests that have vanished from Puget Sound.

Sign up for our email newsletter. Commercial operators who take visitors on whale-watching cruises in the Salish Sea have vowed to follow new, more restrictive guidelines to reduce noise and disturbance around the endangered Southern Resident Killer Whales.

We are fortunate in the Puget Sound region to have easy and free or low-cost access to all sorts of natural places. Deadly climate change could threaten most of the world’s human population by the end of this century without war,ing well beyond those captured in the Paris Agreement.
