Coral Reef Protection & Restoration

[boatman61]

Another thing that makes me chuckle is all these folks on boats going on about their near zero footprint and how AI is going to solve humanities problems..
Yet AI while still in its relative infancy has a carbon footprint equal to Brazil and increasing every day, every Google Search you do has a massive carbon footprint relative to the trivia being searched, God knows Gords carbon footprint when one takes account of what he posts..
No offense Gord..
At the moment all the renewable energy currently in the world can barely maintain existing data centers required to manage the online demands,let alone all the new ones being created every day.
Climate change is here for an indefinite period so best learn to live with it and the ******** from the politicians and self serving 'experts'.

Thanks, for your concern, Phil.

According to Google [1]: “... the energy used per Google search is minimal. In fact, in the time it takes to do a Google search, your own personal computer will use more energy than Google uses to answer your query...”

A typical search returns results, in less than 0.2 seconds. Queries vary in degree of difficulty, but for the average query, the servers it touches each work on it for just a few thousandths of a second. Together with other work performed before your search even starts (such as building the search index) this amounts to 0.0003 kWh of energy per search, or 1 kJ. For comparison, the average adult needs about 8000 kJ a day of energy from food, so a Google search uses just about the same amount of energy that your body burns in ten seconds.

I suspect that Fact Checking [/w 'Google'] myself, prior to posting, probably consumes less energy, than does apologising, when I am wrong.

Gord.. that is a 14yr old answer and likely made by a promo team tasked to minimise any concerns.
The reality is Google, Microsoft etc have little idea of energy consumption and little motive to research it, it's not in thier interest to publicise it even if they did as it would blow up their green washing..
Watch Inside Story on Al Jezeera, AI and Energy, the truth about Data Centres.

Should say I misquoted re Google search, it should have read Chatgpt search uses 10+ times more energy than the old smaller servers.. add to that all the E-mails, movie & music streams and the demand rises.

Data centres will be consuming 1000 terawatts hrs by 2026.

Highest ocean heat in four centuries places Great Barrier Reef in danger

Abstract

Mass coral bleaching on the Great Barrier Reef (GBR) in Australia between 2016 and 2024 was driven by high sea surface temperatures (SST). The likelihood of temperature-induced bleaching is a key determinant for the future threat status of the GBR, but the long-term context of recent temperatures in the region is unclear. Here we show that the January–March Coral Sea heat extremes in 2024, 2017 and 2020 (in order of descending mean SST anomalies) were the warmest in 400 years, exceeding the 95th-percentile uncertainty limit of our reconstructed pre-1900 maximum. The 2016, 2004 and 2022 events were the next warmest, exceeding the 90th-percentile limit. Climate model analysis confirms that human influence on the climate system is responsible for the rapid warming in recent decades. This attribution, together with the recent ocean temperature extremes, post-1900 warming trend and observed mass coral bleaching, shows that the existential threat to the GBR ecosystem from anthropogenic climate change is now realized. Without urgent intervention, the iconic GBR is at risk of experiencing temperatures conducive to near-annual coral bleaching, with negative consequences for biodiversity and ecosystems services. A continuation on the current trajectory would further threaten the ecological function and outstanding universal value of one of Earth’s greatest natural wonders.

And on to purely non-productive stuff like Bitcoin mining ... on a sailing forum. Important, though.

That consumes masses of energy as well, and currently that's mainly provided by fossil fuels which is what is allegedly causing the global warming that is driving climate change which is 'harming the reefs'..
Funny no one assesses the pollution caused by the explosives expended in 'war games' around the world, or the actual wars come to that.. All that oxygen being burnt off.

If your worried about non productive stuff on a sailing site take conversations about Reefs to a scuba and snorkeling site, sailors try to avoid Reefs.
