Great Barrier Reef sees fragile coral comeback

 Yahoo – AFP, Andrew BEATTY, August 4, 2022 

Parts of Australia's beleaguered Great Barrier Reef now have the highest levels of coral cover seen in decades, a government report said Thursday, suggesting the aquatic wonder could survive given the chance. 

Portions of the vast UNESCO heritage site showed a marked increase in coral cover in the last year, reaching levels not seen in 36 years of monitoring, the Australian Institute of Marine Science said. 

Scientists surveying 87 sites said northern and central parts of the reef had bounced back from damage more quickly than some had expected, thanks mainly to fast-growing Acropora -- a branching coral that supports thousands of marine species. 

"These latest results demonstrate the reef can still recover in periods free of intense disturbances," said the Australian Institute of Marine Science's CEO Paul Hardisty. 

But far from declaring victory, Hardisty warned the gains could easily be reversed by cyclones, new bleaching events or crown-of-thorns outbreaks. 

He pointed to a reversal in fortunes for the southern portion of the reef, which a year ago had appeared to be on the mend, but was now in decline again. 

"This shows how vulnerable the reef is to the continued acute and severe disturbances that are occurring more often, and are longer-lasting," he said. 

Coral coverage has increased by 36 percent across sites monitored in the northern part of the reef, up from 27 percent in 2021. 

But the picture was less encouraging as the scientists moved south, with a smaller increase in cover in the reef's central belt and a marked decrease in coral cover in the south. 

The spread of coral-killing crown-of-thorns starfish has also taken a toll. 

Only fierce lobbying by the Australian government stopped the reef from being labelled "in danger" by UNESCO -- a potentially devastating blow to the country's multi-billion-dollar tourism industry. 

Many fear that the speeding rate of damage could cause the reef to be destroyed entirely. 

Marine scientist Terry Hughes said it was "good news" that coral was regrowing, but warned the species driving the recovery were very vulnerable to ocean heating. 

He added that replacing large, old, slow-growing corals that had defined the reef was likely "no longer possible. Instead we're seeing partial reassembly of fast-growing, weedy corals before the next disturbance." 

Zoe Richards a researcher at the Coral Conservation and Research Group at Curtin University also cautioned against over-optimism. 

"This recovery trend is driven by a handful of Acropora species which often grow in a boom-and-bust pattern," she said. "This means that the next thermal stress event could easily decimate these coral communities once again." 

"We are already finding evidence that each mass bleaching event leads to local extinctions of rarer species, so the short-term success of a handful of fast-growing coral species masks the full story about the largely hidden losses of biodiversity."

"....The Prediction: The Renewal of the Life Cycle

When you change the temperature strata of the oceans of the earth, things start to change, for the life cycle of the food in the ocean depends upon that which is the smallest. The plankton of the planet survive in certain temperatures, and that's changing. Throw away what you think you know about how it's all supposed to work, and instead think "renewal" or "how did it begin." This will serve you to understand what is happening now. This cycle is built to replenish the ocean with life and not always by sustaining the kind that was there.

Let us just talk about the ocean for a moment. We won't even get to what's happening in the air and what mammals might experience. Let's just speak of the ocean. Have you heard about the salmon? What has your science warned you against? You're overfishing! The sea is dying. The coral is dying. The reefs are going away. You're not seeing the food chain that used to be there. You've overfished everything. Fishing quotas have been set up to help this. Oh, all those little people in the red room - they don't know about the purple. Red people only know about the red paradigm.

Did you hear about the salmon recently? There's too many of them! In the very place where quotas are in place so you won't overfish, they're jumping in the boats! Against all odds and any projections from environmentalists or biologists, they're overrunning the oceans in Alaska - way too many fish.

What does that tell you? Is it possible that Gaia takes care of itself? That's what it tells you! Perhaps this alignment is going to keep humanity fed. Did anybody think of this? What if Gaia is in alliance with you? What if the increase in consciousness that raised your DNA vibration has alerted Gaia to change the weather cycle and get ready to feed humanity? Are you looking at the ocean where the oil spill occurred? It's recovering in a way that was not predicted. What's happening?

The life cycle itself is being altered by the temperature change of the ocean and much of what you have believed is the paradigm of life in the sea is slowly changing. A new system of life is appearing, as it has before, and is upon you in your lifetime. It will compliment what you know and expose you to a new concept: Gaia regularly refreshes the life cycle on Earth.

Within this process, there will be the extinction of certain plants and animals, birds and fish. My advice to you, especially to those environmentalists, is to understand the cycle of life so that you may relax with what nature has always done. It puts life on the planet to serve the planet for a time. When certain life no longer serves the planet in the ways it used to, it takes it away. The extinction of life, especially through weather change, is normal for Gaia. It is honored, appropriate and normal, even if you don't think so. Don't try to save all the disappearing animals, fish and birds! Some are supposed to go away. And, dear ones, don't assign all this activity to something you did to cause it!

The red people are stressing. The purple is here, and they are trying to figure out what they did wrong. They don't know they are in the Rainbow Room. They think they are in the RED ROOM. This is what the Rainbow Room does; it changes colors. So as the room does what it has always done, the red people are sitting there in fear trying to figure out what it is that they did that possibly could have caused the purple to appear.

The Rainbow Room is beautiful. The color purple is significant. Going from red to purple has metaphysical significance within this parable, but I'll let you figure it out. For those who are into colors, there's a reason why I gave those two. The earth is becoming more sacred than it's ever been before. Gaia is with you in this. It's cooperating in ways you never thought it could, in the way biologists said it would not. You think you're killing it? Instead, it's giving birth to an altered ecological system. ...."

From 2026 hybrid heat pumps should be the norm, says minister

DutchNews, May 17, 2022 

Hybrid heat pumps should become the standard replacement for gas-fired central heating systems from 2026, housing ministerHugo de Jonge said on Tuesday. 

The minister said the deadline was intended to give suppliers, installation companies and property owners clarity about the new situation because ‘the need to become more energy efficient is high and the speed [at which this is being done] must be increased’. 

Households could also opt to switch to the municipal heating network if their local council has set one up, or install a fully electric heat pump if they have the right kind of insulation. 

There will ‘of course’ be an exception for property which is not suitable for heat pumps or district heating schemes, De Jonge said in his briefing to MPs. Steps are also being taken to boost both the number of engineers and the production of heat pumps in the Netherlands.

Heating system suppliers have warned in the past there is a shortage of skilled workers to install the new systems. 

Air 

A hybrid heat pump is a combination of a heat pump, which stores warm air or water, and a central heating boiler and their use leads to an average 60% saving on natural gas consumption, the ministry says. 

In well-insulated homes, it may also be possible to switch directly to a fully electric heat pump, which uses no natural gas at all. 

The government is setting aside €150 million a year in subsidies to help home owners pay for the change, and low income households will also be able to borrow the money at a zero interest rate from special fund. The maximum subsidy available will be up to 30% of the cost.

Targets 

The Dutch government has pledged to ensure all homes in the country are gas free in 2050, aiming for 2,000 in the first two years and building up to 1.5 million homes by 2030. 

Dutch home owners association Vereningen Eigen Huis says the cost of installing a hybrid heat pump is currently up to around €6000 but could be as much as €20,000 for a fully electric pump. 

Insulation 

The VEH, which supports the switch, said three things will be crucial in ensuring the success of the project.

‘It must be affordable, there must be enough capacity in terms of people and equipment, and house owners must be given the right advice about what sort of system to install,’ a spokesman told broadcaster NOS. 

In addition, the property must be properly insulated and that means insulated roofs, floors and walls and at least double glazing, the spokesman said. Those costs will come on top of the cost of the new heating system. 

The Telegraaf points out that the equipment also takes up more space than a traditional boiler and has an outside element which can cause noise issues for neighbours. Properties also may need to add in extra or larger radiators. 

Sector lobby group Techniek Nederland estimates two million of the eight million homes in the Netherlands are currently suitable for hybrid systems.

Dutch stop subsidising heat generation by burning wood chips

 DutchNews, April 23, 2022 

Ministers have agreed to immediately stop giving subsidies for the use of biomass, or wood chips, to generate heat for city heating schemes and greenhouses, the economic affairs ministry has confirmed. 

Dutch biomass plants, which are supposed to help comply with EU climate goals, have been given billions of euros in subsidies in the last few years. They have, however, become deeply controversial because of longer-term damage to the environment. 

‘Organic raw materials play an important role in achieving a climate-neutral and circular economy,’ climate minister Rob Jetten said in a statement. ‘They are also crucial in becoming less dependent on fossil fuels… at the same time, the government is aware of the concerns.’ 

The government, he said, would approve the use of sustainable bio-based raw materials where they make the greatest contribution to sustainability and where alternatives are limited. 

This includes bioconcrete, paint based on bio-based raw, green gas as a replacement for natural gas, or as a fuel for heavy road transport, aviation and maritime shipping. 

Pollution 

In July 2020, the Dutch government’s senior advisory body SER recommended that subsidies for the use of biomass in power stations be phased out quickly. 

However, the Dutch environmental assessment agency PBL says the use of biomass may be unavoidable if the Netherlands is to meet the EU targets. 

Without using biomass, the Netherlands will have to install wind turbines and solar panels more quickly than it is currently doing, and other difficult choices will have to be made, the PBL said. 

The use of biomass, such as wood chips, as a fuel generated an extra 19 megatons in carbon dioxide emissions in 2020, according to calculations by national statistics agency CBS. 

The Netherlands has also been under fire for importing wood chips from the US and the Baltic states to burn in power plants.

Green energy usage topped oil and gas for the first time last week

More than half the energy used in the Netherlands last week came from renewable sources for the first time, according to website Energieopwek.nl, an alliance between gas company Gasunie and national grid groups Tennet and Netbeheer Nederland. 

Almost 54% of the energy used last week was officially classed as green although 10% of the total was generated by biomass, which campaign groups do not always consider to be sustainable. Solar power accounted for 11% and wind energy 31%. 

Although the number of wind turbines and solar panels in the Netherlands has expanded considerably, last week’s windy, yet sunny, weather also had a major role in the record-breaking week. 

The use of biomass, or organic material, is controversial because the Netherlands imports large quantities of wood chips from abroad to burn in power stations.
