Reef Insurance | Earth Wise

January 4, 2023 By EarthWise Leave a Comment

Insuring coral reefs

Coral reefs around the world face multiple dangers from warming waters, acidification, human activity, and more.  Powerful storms often cause tremendous damage to reefs.  When possible, snorkelers and divers are deployed to try to repair damage to reefs.  But philanthropy and government grants are basically the only resources available to fund such actions.

Three years ago, tourist businesses and the government in the Mexican state of Quintana Roo purchased an insurance policy to offset costs of protecting the local parts of the Mesoamerican Reef.  The environmental group the MAR Fund later took out an insurance policy on the rest of the reef in Mexico, Belize, Guatemala, and Honduras. 

With this precedent, the Nature Conservancy recently purchased an insurance policy on behalf of the state of Hawaii to help offset repair work on its coral reefs.  It is the first U.S. coral insurance contract.

Coral reefs are more than just hosts for marine life.  They provide barriers against ocean storm surges, which is a major financial incentive for protecting them and hence an incentive to invest in insurance.

The new Hawaiian insurance policy has a premium of $110,000 a year and will provide $2 million in protection.  Payouts occur when wind speeds go above 50 knots.  No further proof of damage is required.

The Nature Conservancy has created teams called ‘Reef Brigades’ composed of snorkelers and divers who recover reef fragments, store them in ocean or shore-based nurseries, and then re-attach them when conditions are safe.  It can be very expensive to do this sort of work, particularly when new corals grown in a nursery are required.

Life In The Great Pacific Garbage Patch | Earth Wise

June 14, 2022 By EarthWise Leave a Comment

The world’s oceans contain five gyres, which are large systems of circular currents created by global wind patterns and the Earth’s rotation.   Gyres act like gigantic whirlpools.  Anything that floats into one of them eventually ends up in the center.   Ever since floating plastic waste started entering the ocean, it has poured into these gyres and created so-called garbage patches.  The largest of these is the Great Pacific Garbage Patch, located halfway between Hawaii and California.  According to the Ocean Cleanup Foundation, the Great Pacific Patch contains at least 79,000 tons of plastic.

A recent study has shown that the garbage patch is not just a place where drifting plastics aggregate; it is also a place where drifting animals aggregate.

It turns out that the Great Pacific Garbage Patch is absolutely teeming with life, primarily small surface-dwelling animals that are collectively known as neuston.  A ship surveying the garbage patch found that in some places, there were nearly as many neuston as there are pieces of plastic.

Typical creatures in the patch are blue dragon nudibranchs, Portuguese man-o-wars, anemones, sea snails, blue buttons (which are related to jellyfish) and hydrozoans.  It appears that these creatures are reproducing within the garbage patch.  Little is actually known about the life history and ecology of these creatures, so that studying the garbage patch is offering valuable insights to scientists.

Two nonprofit organizations are working to remove floating plastic from the Great Pacific Garbage Patch.  Evidently, removing this existing pollution from the ocean is likely to have unexpected effects on the local ecosystem and is a source of at least some controversy.  One thing that isn’t controversial, however, is that we need to stop the flow of plastic into the ocean.

Five States Stepping Up On Clean Energy | Earth Wise

February 7, 2022 By EarthWise Leave a Comment

Five states step up climate action

While Congress continues to face partisan gridlock on climate issues, many states have moved forward with climate action.

In 2021, five states – Illinois, Massachusetts, Oregon, North Carolina, and Rhode Island – passed laws requiring a shift to 100% carbon-free electricity or net-zero emissions.  Washington State passed a law that helps to implement its strong 2019 and 2020 climate and clean energy laws.  Washington’s new legislation establishes a carbon trading program that will help the state to meet its goals of economy-wide emission cuts and 100% carbon-free electricity.

Several other states made progress on climate and clean energy by taking targeted actions not quite as aggressive as 100% laws, but significant, nonetheless.

The five states that entered the so-called 100% club joined with the six states that had earlier passed such legislation.  Those are California, Hawaii, New Mexico, New York, Virginia, and Washington.  Both Puerto Rico and Washington D.C. are also members of the club.

The past year may well be the biggest year yet for significant clean energy legislation.  Some of the states that finally passed laws had been gearing up for it for years.  This is particularly true of Massachusetts and Illinois.

Actions by individual states are not an antidote to inaction by the federal government, but they help.  At this point, about one-third of the country’s population lives in states that have laws requiring a transition to 100% carbon-free electricity, 100% renewable electricity, or net-zero emissions. 

All of this activity began in 2015, when Hawaii passed its renewable energy law.

Bomb Cyclones | Earth Wise

December 2, 2021 By EarthWise Leave a Comment

Extreme weather phenomena becoming increasingly common

It seems like we are hearing about new weather phenomena pretty frequently these days.  One name that has popped up lately is “bomb cyclones.”  Bomb cyclones, it turns out, are storms that undergo “bombogenesis.”  What that means is a low-pressure area (in other words, a storm) that undergoes rapid strengthening and can be described as a weather bomb, or popularly, a bomb cyclone.

These things usually take place over remote tropical ocean areas but a really intense one struck the Pacific Northwest on October 24th.  The storm off the coast of Washington, with a barometric pressure reading equivalent to a category 4 hurricane, was the second extreme low-pressure storm in the North Pacific in a single week.  Both storms involved pressure drops of more than 24 millibars in 24 hours, making them bomb cyclones.

These storms brought high winds and extreme precipitation that doused wildfires and provided some relief to the extreme drought in Central and Northern California.  Along with these positive effects, however, the storms also caused power outages, flooding, landslides, and mud and debris that washed out roads.

The October 24-25 event brought 16.55 inches of rain to Mount Tamalpais in Marin County, California in a 48-hour period.  Sacramento got 5.44 inches of rain, breaking a 140-year-old record.  And the city had just broken another extreme weather record for the longest dry spell in history.

The storms directed streams of moisture from north of Hawaii toward the West Coast in long, narrow bands of moisture known as atmospheric rivers.  We are learning about all sorts of unfamiliar weather phenomena as extreme weather events become increasingly common.

Sunscreen For Corals | Earth Wise

August 6, 2021 By EarthWise Leave a Comment

Scientists examine why some corals are better equipped to survive a changing environment

Sunscreen from beachgoers entering ocean waters is one of the greatest threats to coral reefs and there are global efforts to reduce or eliminate the use of many of the most harmful chemicals people use to protect themselves from the sun’s rays.  However, scientists at the Smithsonian Conservation Biology Institute have found that some corals have a natural sunscreen of their own that helps protect them from the effects of climate change.

Hawaiian blue rice corals feature a deep blue pigment that is created by chromoprotein that filters out harmful ultraviolet radiation from the sun.  UV damage has harmful impacts to reproduction in many coral species, but it appears not to have the same effect on blue rice coral.

In a study published in Scientific Reports, Smithsonian researchers studied the devastating effects that bleaching had on brown rice coral in the Hawaiian bleaching events of 2014 and 2015.  During the same events, blue rice coral either recovered quickly or was not affected by the elevated ocean temperature at all.

The blue-pigmented corals had dramatically greater reproductive vigor than the brown-pigmented version.  The key factor appears to be the sun-screening ability of the blue pigment in the particular symbiotic algae that lives inside the coral tissue known as zooxanthellae.  The coral protects the algae and in turn the algae provide the coral with food in the form of sugars produced as a waste product from photosynthesis.  In the case of the blue version, the algae also produce sunscreen for the coral.

By better understanding the role UV-protective pigments play in mitigating the adverse effects of climate change and warming oceans, scientists can learn why some species are better equipped to survive in a changing environment.

Hardier Corals For Endangered Reefs | Earth Wise

July 26, 2021 By EarthWise Leave a Comment

Developing hardier corals to resist the effects of climate change

Mass coral bleaching events are getting increasingly frequent as the oceans continue to warm, endangering coral reefs all over the world. The damage to Australia’s Great Barrier Reef has been enormous and in 2015, nearly half of Hawaii’s coral reefs were affected by a severe bleaching event.

Not all coral bleaching is permanent.  Corals can sometimes recover.  Some corals even seem to resist bleaching altogether.  Researchers from the University of Pennsylvania studied these resilient corals to see just how effective they are in resisting the effects of climate change.

Their experiments sought to determine whether corals that seem to resist bleaching can be moved to other locations and used as the seed stock to repopulate degraded reefs.

The researchers identified coral colonies that resisted bleaching during the 2015 Hawaiian bleaching event and collected samples from them.  They transplanted some of them to a second reef as well as putting other samples in laboratory tanks and simulating a bleaching event by raising the water temperature over a period of several days.

Careful tracking of the corals’ health showed that the bleaching-resistant corals stayed that way even in a new environment and under additional stress.  They also studied how well the corals reproduced and found that the corals that spent time in a favorable new site before being subjected to stress demonstrated greater fitness and improved reproduction.

The study indicates that coral transplantation using colonies known to be resistant to bleaching may be an effective way to buy some time in preserving the world’s coral reefs.  But global action on climate change is essential because even bleaching-resistant corals aren’t going to survive forever if ocean warming keeps increasing.

Floating Renewable Energy | Earth Wise

July 22, 2021 By EarthWise Leave a Comment

The next generation of offshore energy is under development

A team of researchers at Texas A&M University believes that the next generation of offshore energy could come in the form of a synergistic combination of multiple renewable energy generators installed on a floating offshore platform.

Their concept for the ocean renewable energy station comprises wind, wave, ocean current, and solar energy elements that could generate electricity for anything from a coastal or island community to a research lab or military unit.  The station would be tethered to the sea bottom and could be used in locations where the water depth increases quickly, such as along the U.S. Pacific Coast or Hawaii.

Offshore wind is already commercially competitive, while wave-energy converters so far have been less cost-effective and only useful for specialized, smaller-scale applications.  The proposed ocean renewable energy station would make use of multiple different methods of electricity generation and incorporate innovative smart materials in the wave energy converters that respond to changes in wave height and frequency and allow for more consistent power production.

Denmark is already building a huge multi-source, multi-purpose ocean energy island.  This world’s first energy island will be 30 acres in area and serve as a hub for 200 giant offshore wind turbines generating 3 GW of electric power.  It is the largest construction project in Danish history, and will cost an estimate $34 billion.  As well as supplying other European countries with electricity, the goal is to use the new offshore island to produce green hydrogen from seawater, which can also be exported.  Large battery banks on the island will store surplus electricity for use in times of high demand.

Record Carbon Dioxide Levels | Earth Wise

June 29, 2021 By EarthWise Leave a Comment

Carbon dioxide levels set another record despite pandemic shutdowns

The coronavirus pandemic caused a temporary dip in the burning of fossil fuels around the world as many human activities were diminished or curtailed entirely.  Despite this, the amount of carbon dioxide in the atmosphere set a record in May, reaching the highest levels in human history.

Scientific instruments atop the Mauna Loa volcano in Hawaii measured an average of 419 parts per million for the month, according to analysis from both the Scripps Institution of Oceanography and the National Oceanic and Atmospheric Administration.

This level is about half a percent more than the previous record of 417 ppm, set in May of 2020.  Carbon dioxide is the largest greenhouse gas contributor driving global warming and, according to scientists, there hasn’t been this much of it in the atmosphere for millions of years.

Global emissions of carbon dioxide were actually 5.8 percent lower in 2020 than 2019, as a result of pandemic lockdowns.  This was the largest one-year drop ever recorded.  But humanity was still responsible for emitting more than 31 billion tons of carbon dioxide last year.  About half of that CO2 is absorbed by the world’s trees and oceans, but the other half lingers in the atmosphere for thousands of years, gradually warming the planet via the greenhouse effect.

As long as we keep emitting carbon dioxide, it is going to continue to pile up in the atmosphere.  The only way to stop it is for the world’s nations to zero out their net emissions, mostly by switching away from fossil fuels to technologies that do not emit carbon dioxide, such as electric vehicles fueled by wind, solar, or nuclear power.

Essential Oils And Organic Crops | Earth Wise

November 6, 2020 By EarthWise Leave a Comment

Essential oils as natural pesticides

Essential oils are concentrated liquids extracted from plants.  They are called “essential” in the sense that they contain the essence of the fragrance that is characteristic of the plant.  Essential does not mean indispensable or usable by the human body.  But despite that fact, essential oils have been used in folk medicine throughout history. 

In recent times, essential oils have frequently been used in aromatherapy.  Generally speaking, medicinal uses of essential oils are controversial, and, in some cases, they have even been demonstrated to be dangerous.

Research has shown that essential oils have potential as natural pesticides.  Recently, the USDA has funded research into the use of essential oils to battle pests and diseases of organic crops.

U.S. organic food sales topped $50 billion in 2018 and fruits, vegetables, and other specialty crops combined make up more than a third of organic sales.  In order to meet consumer demand, farmers need ways to battle pests and diseases that often accompany organic crop growth.

A four-year project at the University of Hawaii at Manoa is entitled “Plant Safety, Horticultural Benefits, and Disease Efficacy of Essential Oils for Use in Organically Grown Fruit Crops:  From the Farm to the Consumer.”   The researchers will work with certified organic producers in Hawaii, Florida, South Carolina, Georgia, and California to evaluate the effectiveness of plant essential oils on major fruit pathogens such as avocado scab, anthracnose fungal disease, and powdery mildew on targeted tropical and temperate fruit crops such as avocado, mango, blueberry, and peach.

The goal is increase orchard productivity of the expanding organic fruit industry.

A New Kind Of Coral Nursery

October 22, 2019 By EarthWise Leave a Comment

Coral reefs around the world are struggling from warming waters and increasing ocean acidification driven by excess carbon dioxide.  Many of the world’s greatest reefs – such as Australia’s Great Barrier Reef – have seen steep declines over the past decade.

But apart from the global environmental threat, reefs also are often damaged by various marine accidents such as ships grounding on them.   Such events can severely damage a reef and scatter countless small coral fragments onto the seafloor.  These small pieces of coral are not actually dead; they can continue on with their lives if they are relocated to a suitable environment such as a coral nursery.

Coral nurseries are generally small installations that allow coral fragments – typically pieces about 4 inches in length – to recover from their reef breaking up and to grow until they are large enough for conservation managers to replant them into reefs that need them.  This strategy works well in places where corals grow relatively quickly – such as Florida and the Caribbean – but not as well in places where coral grows more slowly, such as Hawaii.

Recently, coral experts at the National Oceanic and Atmospheric Administration working with mechanical engineering students at the University of Hawaii have developed a new type of coral nursery that can save fully formed coral colonies as opposed to small coral fragments.

The nurseries are large, carefully designed structures that can be loaded up with corals that have become detached from their reefs.  Some of these new structures were installed in the waters of Oahu in the summer of 2018 and were populated with corals.  The relocated corals, which would have otherwise died, are now recovering nicely in their new coral daycare centers and will soon be replanted back into the reef.

Packing With Banana Leaves

July 25, 2019 By EarthWise Leave a Comment

More and more places are instituting bans on single-use plastic bags.  Places like California and Hawaii already have bans in place and New Jersey is considering such a ban.  New York’s law will go into effect next March.  Supermarkets will no longer provide plastic bags at the checkout line.  But the laws have some exceptions, including the plastic bags used to hold produce and to pack up meats.

Banning or reducing single-use plastic bags is a growing trend in Asia as well including places like South Korea, Vietnam and Thailand.

One supermarket in Thailand came up with a novel approach to eco-friendly packaging:  wrapping produce in banana leaves.  The idea quickly became a viral hit on social media and drew the attention of supermarkets in Vietnam.  Several big supermarket chains in that country also began experimenting with banana leaves as a packaging alternative.

Representatives of Vietnam’s Lotte Mart chain said that the banana leaf packaging was still in the testing phase, but they plan to replace plastic with leaves nationwide very soon.  Aside from wrapping vegetables and fruits, the grocery chain intends to also use the leaves for fresh meat products.

Customers seem to be quite positive about the new packaging noting that it is actually quite attractive visually.  The banana leaf packaging also makes people more aware of the need for protecting the environment.

While Vietnam is a relatively small country, it turns out that it ranks number four in the world for the largest amount of plastic waste dumped into the ocean.  The country disposes of about 2,500 tons of plastic waste per day. So, efforts like the banana leaf packaging are not just symbolically important, they are genuinely a major environmental imperative.

Getting Rid Of Plastic Here And Abroad

May 23, 2019 By EarthWise Leave a Comment

Efforts in the fight against plastic pollution are really stepping up these days. 

New York State lawmakers have agreed to impose a statewide ban on most types of single-use plastic bags from retail sales.  The ban would be the second statewide ban after California, which banned the bags in 2016.  Hawaii effectively also has such a ban since all of the state’s counties have their own bans.

The New York ban would begin next March and would forbid stores from providing customers with single-use plastic bags.  There are a number of exceptions, including food takeout bags in restaurants, bags used to wrap deli or meat counter products, and newspaper bags.  New York counties could opt into a plan to charge a 5-cent fee on paper bags, with proceeds going to the state’s Environmental Protection Fund.  Some environmentalists point out, however, that paper bags have their own issues.  While they do decompose in landfills, they have a substantial carbon footprint since they are made from wood and being heavier, they are more costly to ship.  Business groups are concerned about the forthcoming ban based on increased costs.

Meanwhile, European Union member states have reached a provisional agreement to introduce restrictions on single-use plastic products.  In 2021. European citizens will say goodbye to plastic cutlery, plastic plates and plastic straws among other products.

According to the European Commission, plastics make up 85% of beach litter in the Mediterranean.  Large plastic pieces injure, suffocate, and often kill marine animals but microplastics have reached record levels of concentration – over a million fragments per square kilometer – in the Mediterranean.

Both here and abroad, the war on plastics is heating up.

Forecasting A Bad Year For Carbon

March 11, 2019 By EarthWise Leave a Comment

Carbon dioxide levels in the atmosphere are higher than they have been for hundreds of thousands of years, and they continue to grow.  The United Kingdom’s national meteorological service – known as the Met Office – issues annual predictions of global CO2 levels based in part on readings taken at the Mauna Loa observatory in Hawaii.  Their forecast for this year is that there will be one of the largest rises in atmospheric carbon-dioxide concentration in the 62 years of measurements at Mauna Loa.

Since 1958, there has been a 30% increase in the concentration of carbon dioxide in the atmosphere.  This has been caused by emissions from fossil fuels, deforestation and cement production.  The increase would actually have been even larger if it were not for natural carbon sinks in the form of various ecosystems that soak up some of the excess CO2.

Weather patterns linked to year-by-year swings in Pacific Ocean temperatures are known to affect the uptake of carbon dioxide by land ecosystems.  In years with a warmer tropical Pacific – such as El Niño years – many regions become warmer and drier, which limits the ability of plants to grow and to absorb CO2 .  The opposite happens when the Pacific is cool, as was the case last year.

The Met Office predicts that the contribution of natural carbon sinks will be relatively weak, so the impact of human-caused emissions will be larger than last year.  The predicted rise in atmospheric CO2 is 2.75 parts-per-million, which is among the highest rises on record.  The forecast for the average carbon dioxide concentration is 411 ppm, with peak monthly averages reaching almost 415 ppm.  With global emissions not really declining, the numbers just get higher and higher.
