Stanford research on whale feeding highlights how the precipitous decline of large marine mammals has negatively impacted the health and productivity of ocean ecosystems. Nextbigfuture had a video highlighting the problem of lack of whales and whale poop. Nextbigfuture also identified how iron fertilization of the ocean by humans could take the place of whales …
On December 12, 2019, the non-profit Ocean Cleanup succeeded in pulling out its first main load of plastic from the ocean. Mission One took their first plastic catch onshore, in Vancouver Canada. The plastic trash will be transformed into sustainable products that will be sold to help fund the continuation of the cleanup operations. To …
China has formed an innovation alliance to foster the research and application of extracting uranium from seawater, according to China National Nuclear Corporation (CNNC). The alliance involves around 20 research institutions and universities. Uranium has been extracted in small quantities from the ocean. However, the cost is about $400-600 per kilogram. This is about 7 …
Seaweed to Offset Emissions Will Mainly Be Reducing Methane from Farm Animals
Changing energy and transportation in the US in an expensive way will not by itself deflect world greenhouse gas emissions. It will cost about $50-200 per ton of CO2 doing it that way. And it will take many decades. The US emits over 5 billion tons of CO2 emissions per year. The world emits 37 …
The vast subtropical “gyres” – large systems of rotating currents in the middle of the oceans – cover 40 percent of the Earth’s surface and have long been considered biological deserts with stratified waters that contain very little nutrients to sustain life. These regions also are thought to be remarkably stable, yet scientists have documented …
There is another doomer scenario that civilization will collapse because of climate change. This new doomer report is from the Australian National Centre for Climate Restoration. All of the climate change doomer scenarios assume that the only way to adjust the atmosphere over the next several decades is to reduce emissions from vehicles, energy generation …
Ocean acidification is the ongoing decrease in the pH of the Earth’s oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere. Seawater is slightly basic (meaning pH is over 7), and ocean acidification involves a shift towards pH-neutral conditions rather than a transition to acidic conditions (pH less than 7). An estimated …
78% (830,000 tonnes) of the 2018 U.S. plastic waste exports were sent to countries with waste “mismanagement rates” greater than 5%. Mismanagement means the plastic was probably dumped in a river. The actual mismanagement rates in China, India and Vietnam are 78-85%. Mismanaged “recycled” plastic probably ended up in the ocean. Plastic waste has been …
What if we could stop temperature rise and roll back world temperatures as needed? What if we could fix the atmosphere without wrecking the economy but just added a profitable business? Do we have to completely change energy, transportation and the economy BEFORE the effects of climate change are very large and clear? Do we …
