A possible problem in the future with climate change may be the availability of fresh water...

"Ms Hunt is chief innovation officer for a Canadian start-up called Oneka Technologies. It has developed floating desalination systems that turn seawater into fresh water.

While large, shore-based desalination plants typically require vast amounts of energy to remove the salt, Oneka's small units are powered solely by the movement of the waves.

"Desalination facilities are conventionally powered by fossil fuels," says Ms Hunt. "But the world has certainly reached a pivot point. We want to move away from fossil fuel powered desalination."

More than 300 million people around the world now rely on desalinated water, according to the global trade body, the International Desalination Association. This water is supplied by more than 21,000 plants, almost twice as many as there were 10 years ago."

The desalination plants exist and are being powered. If they get turned off that is not going to be the fault of climate change. It will be the fault of dik inspired hysteria.

 

[dik]

Nope, Tug... this could just be another 'green' source of 'fresh' water if it becomes necessary in future.

The notion of powering desalination with renewables is laughable. We can live with unreliable power. We can't live with unreliable water.

 

[dik]

Powering desalination with wave or tide powers seems to be almost as reliable as fossil fuel. The latter may become in short supply.

The obvious way to power a desal plant is from your nukes when electrical demand is low, rather than throttling the nukes.

The whole concept of wave generation is absurd. Waves are powered by the wind. Why would you add extra steps?

And tidal generation? Where is the potential energy? It's not from height and it's not from velocity. The turbine required would be immense. It's also not so friendly for the estuaries it would be plugging up.

The fact that anyone would suggest such preposterous ideas demonstrates their disconnect from reality.

 

[GregLocock]

I just checked. The total installed capacity (not output) of wave power stations globally is .... 10 MW. (as of 2015), by 2020 it was more like 20 MW less failures.

If I might indulge in a lame emoticon since they seem to fashionable

More seriously I have seen a lot of money poured into wave power over the years and after some initial enthusiasm the demonstration projects sink from sight within 2 years.

...a heads up.

"The effects of a rapidly warming climate are being felt in every corner of the US and will worsen over the next 10 years with continued fossil fuel use, according to a stark new report from federal agencies.

The Fifth National Climate Assessment, a congressionally mandated report due roughly every five years, warned that even though planet-warming pollution in the US is slowly decreasing, it is not happening nearly fast enough to meet the nation’s targets, nor is it in line with the UN-sanctioned goal to limit global warming to 1.5 degrees Celsius – a threshold beyond which scientists warn life on Earth will struggle to cope.

This year’s assessment reflects the reality that Americans can increasingly see and feel climate impacts in their own communities, said Katharine Hayhoe, a distinguished climate scientist at Texas Tech University and contributor to the report.

“Climate change is affecting every aspect of our lives,” Hayhoe told CNN.

Some of the report’s sweeping conclusions remain painfully familiar: No part of the US is truly safe from climate disasters; slashing fossil fuel use is critical to limit the consequences, but we’re not doing it fast enough; and every fraction of a degree of warming leads to more intense impacts.

But there are some important new additions: Scientists can now say with more confidence when the climate crisis has made rainstorms, hurricanes and wildfires stronger or more frequent, long-term drought more severe and heat more deadly."

What is the purpose of a scientist if there are only certain things they "can" say?

 

[BridgeSmith]

Self-proclaimed 'scientists' can say whatever they want, but it doesn't make it true or a fact. Lots of scientists were sure that all the other planets, the sun, etc. orbited around the Earth, and that the way to cure diseases was to let the 'bad' blood out.

Btw, the heat today is far less deadly than it has been in the past.

 

[TugboatEng]

It won't be less deadly if we stop using fossil fuels.

 

[GregLocock]

" 1.5 degrees Celsius – a threshold beyond which scientists warn life on Earth will struggle to cope." Our monkey ancestors were just fine in higher temperatures, and they didn't have A/C, and they had fur.

Also funnily enough, the trend of current migration is towards warmer places from colder places. So people choose warmer places.

[TugboatEng]

Please, dik, from now on when you mention a scientist can you please define the word scientist because you seem to have a twisted definition. Also include credentials before job title. Job title isn't a descriptive term.

 

[dik]

Still not much of an improvement...

"“Despite decades of warnings from the scientific community, thousands of pages of reports and dozens of climate conferences, we are still heading in the wrong direction,” WMO Secretary-General Petteri Taalas said.

This month, the UN’s annual climate summit is scheduled to start in Dubai and could include a push to phase out the use of fossil fuels before 2050. But thus far, countries that account for large shares of the world’s carbon emissions have fallen far short of the cuts needed."

[TugboatEng]

And why is this meeting being held in Dubai?

 

[dik]

...likely political reasons. You don't think the world governments are concerned about climate change, do you?

[TugboatEng]

A few reasons:

-It is far from the attendees so the CO2 cost of attendance is very high.

-Dubai is a symbol of opulence and excess. Not conservation.

-Dubai is proof that humans can thrive in hot climates.

It's very bad optics. It's as if the attendees are more interested in the trip than the conference.

 

[BridgeSmith]

It's as if the attendees are more interested in the trip than the conference.

Nah, that couldn't be it, could it?

It's probably just because there's enough room for them to all park their private jets, unlike some of the other exotic locations where climate conferences have been held in recent years.

How Dare You!^TM

LOL

The problem with sloppy work is that the supply FAR EXCEEDS the demand
