Climate change is here

[zigs]

Water is a precious commodity in Perth. You would think they could drain it off progressively, so it is stored in drainage ponds rather than accumulating and running in waves down the roads. Let's hope we learn from this.

We've just had months of rain to the extent that it's filled all the chalk aquifers here, rivers that are normally dry valleys are flowing. Last week they said we'd have hosepipe bans in the summer as they haven't collected enough of it

Our population has gone up by 15 million since I was a Ziglet and they haven't built any new reservoirs for years. We're surrounded by new housing but there's no extra water to supply them. We've installed 4,000 litres of rainwater storage and also have water purifying stuff for emergencies.

Did the same as he did on my old gardening forum, came in like a seventh sense, told everyone how everything is done and then gets the hump when people disagree with him before buggering off

I kind of feel sorry for trolls, they're just looking for a little attention...I guess I got a little soft spot for trolls

I can't understand the huge development in solar when wind is such a known and simple technology, especially over here on an off shore island. In Orkney most people have a small wind turbine that feeds into the grid and it produces so much the power line to the mainland can't handle it all, they could produce all the electricity the UK needs with a reasonably small investment. In my book a small turbine at the end of every garden would be far better than solar panels on every roof. No lithium for a start.

I get your point about wind energy, but solar has its own advantages too. Solar panels can be deployed almost anywhere, from rooftops to large solar farms. They need less maintenance and can be installed where wind turbines might not be practical, which is why we see so much development in solar. Some solar installers even offer insurance against weather-related damages like fire, lightning, and hail storms. Plus, community solar projects allow people who can't install panels on their roofs to benefit from solar energy. https://www.energy.gov/eere/solar/community-solar-basics

In places like Hawaii, there are awesome incentives for residents to go solar, making it a great option even in island settings. You can get more details about these incentives here: https://hawaii.statesolar.org

My opinion yes Climate is changing but not that much from human usage.

Some countries are very polluted but people are still making do.

First hand knowledge I've spent many days down on the Southern Border and you can actually see smog coming North.

They are talking about the Pacific Ocean being warmer. Is it possible the plate is getting thinner there?

It breaks loose and we all die how is this Human fault? Do you really think the Government is going to tell you the planet is going to fall apart? Hey they know there is nothing they can do might as well make the best of it for now.

The problem with solar is water in the air. Water has this affinity for absorbing energy. Its useful really, as we use it in the radiators of our cars and in the nuclear power plants and so forth. It is the mainstay of what is called the Carnot Cycle. But for so many areas it is not a panacea. Here in Alabama for example our humidity is so high the glare (oh that too its misdirected light basically) and ir absorbtion alone makes it less than stellar on a cost per watt etc etc etc. Irritatingly, when I thought I had a grasp on the whole idea of the differences between solids, liquids and gasses the idea of a water condition that was in between liquid and gas was introduced to me and I immediately changed my major to engineered marketing.

Also dont leave water drops on plant leaves in midday as it absorbs so much heat before evaporation it will burn them.

PS. Thanks for the 1990 memories. That guy that taught the class had a masters in mechanical engineering. He told us that if you could improve the power production efficiency of the Carnot Cycle by .25 of One percent you would be the richest person on the planet. It explains a lot of observations.

If you are dead set on saving the planet, you need to expand your mind so look at really big picture stuff instead of electric fence chargers:

'Absolute miracle' breakthrough provides recipe for zero-carbon cement

Concrete and steel production are major sources of CO2 emissions, but a new solution from Cambridge could recycle both at the same time. Throwing old concrete into steel-processing furnaces not only purifies iron but produces “reactivated cement” as a byproduct. If done using renewable energy, the…

@DirtMechanic, Your point about cement production is a very valid one, huge producer of CO2 and on the whole for very little gain in quality of life. Living in a mud floor hut the quality is improved greatly by a concrete slab floor. If you are working in an office the move from a traditional building to a skyscraper gives only a fractional improvement.
