The blob is back. A meteorologist says unseasonable conditions in B.C. are likely once again causing a large area of the Pacific Ocean to heat up, emulating a phenomenon from past years called the “blob.” That mass of warm water was blamed… Read More ›

Our Ocean Connection: The Challenges, The Cures
By Charmaine Coimbra Dominoes. It’s like 150 years of stacked dominoes collapsing in four directions from Rugby, North Dakota, North America’s geographical center and from every geographical center of every continent on Planet Earth—with the final dominos landing in every… Read More ›
“When ice melts in the Arctic, the west burns”
Last week, scientists learned that 40-foot piles of compacted sea ice — some of the oldest and most durable clusters in the Arctic — are breaking away from the coast of Greenland and drifting out to sea. One meteorologist called… Read More ›
Marine Heat Waves Impact Marine Life
Between 1982 and 2016, the number of “marine heat waves” roughly doubled, and likely will become more common and intense as the planet warms, a study released Wednesday found. Prolonged periods of extreme heat in the oceans can damage kelp forests and coral reefs, and harm fish and other marine life.
Harmful Algae Increase
Blooms of harmful algae in the nation’s waters appear to be occurring much more frequently than in the past, increasing suspicions that the warming climate may be exacerbating the problem. The Environmental Working Group (EWG) published newly collected data… Read More ›
Canada & Mexico to Discuss Plastics in Ocean
“From acidification to the worsening impacts of hurricanes, climate change is negatively affecting our oceans and coastal communities. In addition, plastic waste and marine litter pose an increasingly serious threat to our oceans, marine life, and human health. In fact, there is so much plastic in our oceans that, without action, it is estimated there will be more plastics in our oceans than fish, by 2050. This global problem requires action, and Canada is working with international partners to see our oceans protected from waste and the impacts of climate change. As Canadatakes on the G7 presidency in 2018, we will continue to advance global efforts on climate change, oceans, and clean energy.”
– Catherine McKenna, Minister of Environment and Climate Change
2017–Warmest Year on Record for Oceans
But in terms of understanding how fast the Earth is warming, the key is the oceans.
Tree Ring Study and Jet Stream Changes
From Science Daily Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, droughts, wildfires and flooding, reports a University of Arizona-led team. The… Read More ›
Acidification Impacts Puget Sound’s Oyster Farms
It’s a calamity that threatens Washington state’s $270-million-a-year shellfish industry. And it has the Taylors — after a century-plus producing shellfish in the Evergreen State — exploring every potential angle to steel their mollusks against the corrosive effects of ocean acidification.
Nitrite Pollution Increase in Ocean Water
Researchers have more than once warned of “dead zones” and toxic algal blooms as a consequence of changing climatic conditions. Ocean temperatures are increasing, and this in turn encourages a new set of biochemical processes.
Professor Hollibaugh and a colleague report in the journal Environmental Science and Technology that over the course of eight summers they measured peaks of nitrite, alongside massive increases in the numbers of the microorganisms that produce it, in coastal waters off Georgia.
