I don't care how they try to package it, artificial grass is just a terrible thing for the natural world. I for one will never ever consider it.
Just more green coloured plastic pollution. The absolute last thing we need with man made climate change and the diminished wildlife.
Come on people. Do the right thing for a change.
If you can not be bothered with a lawn, plant ground cover.

We need to just bin the idea of the green grass lawn being essential to a household altogether. The disproportionate amount of air, water, and earth being wasted or abused relative to a lawn’s value to society is absurd.
Absolutely. Long-term, I want to cover as much of my terrain with bushes and flowers as I can, but for now, I'm at least seeding white clover with the grass. It grows well and complements the grass (nitrogen-fixing clover with nitrogen -extracting grass).
Much better than constant fertilizing and watering! (Even if this kind of hot and dry summer isn't kind on any kind of plant.)
I do understand that point, especially with climate change.
Nevertheless, we are fortunate enough to have a reasonable size back lawn.
And one of the pleasures of this is to provide feeding opportunities for birds especially.
And because it is normally green, it is taking in carbon and giving out oxygen.
You could make the same argument for trees and bushes as they use way way more water than grass, golf courses aside.
We are only sharing this planet with the wildlife and ecosystem. It is not ours.
Our atmosphere is because of photosynthesis. And manufacturing artificial grass from fossil fuels when we are trying to limit the effects of climate change is to my very simple mind totally at odds with what we claim we are trying to do.
Not climate change, but certainly a change to the climate.
Apart from a small minority, we understand that man made climate change is the result of humanity pumping evermore greenhouse gases into our finite atmosphere.
But one question keeps popping into my head.
What is happening to all that heat that we are generating as well from either fossil or renewable sources.
The vast majority of the energy we consume is converted into heat. And that of course must include heat from friction and sound.
It has to remain as heat energy until it might be converted into another form.
So why is the heat we are busy generating not a source of temperature rise?

I can follow your gist but the sun has been heating the planet for ever.
What happens to that heat differently to generated heat energy
Heat is heat.
Maybe I'm wrong.
It may make some differences but there are much bigger concerns though. For instance, the biggest cause of deforestation being animal agriculture. The easiest and biggest change people can make is making their diet as predominantly plant-based as possible but most people can't even be arsed doing that.
And I too understand your point.
However, the sun's energy will heat our planet to a (broadly) average given temperature.
But what I am referring to is all of that additional heat humanity has been adding since the Industrial Revolution.
The laws of energy conservation say that energy will remain in one form (of energy) until it is converted into another form.
Does this help re: human bodies?

The Earth also sheds heat into space:

Sorry if I have misunderstood.
Yes.
I completely agree with you that artificial grass instead of natural grass is a 2nd order effect when compared to the really big issues.
All I am saying is that, knowing what we now know, why would any reasonable minded person have artificial grass.
Oh wait. I have just answered my own question.
Thank you matey.
And it looks like it is me who has misunderstood the science, not you.
I worked in hyperscale data centers for years and Id go to the roof where all of the extract ducts vented the hot air to atmosphere.
Believe me on roof of a 50MW data centre there is alot of air handling units. Each one designed to suck the waste product from data halls.
The waste product is heat. Millions of cubic Mtrs of super heated air extracted every day. 24/7.
Where that data centre campus is there are 10 more over 3 sq miles.
Dumping untold amounts of waste heat to the sky.
It's Mind-boggling when you feel the power of it
The Earth also loses 90 tonnes of its atmosphere into space every day too, along with heat: https://sciencenorway.no/space-space-research/why-doesnt-all-our-air-disappear-into-space/1870565
I can imagine.
I guess the answer is that man-made heat output is nothing like as significant as man made greenhouse gas output.
It sounds like a lot, but it's basically nothing. It's an interesting fact, though!
Also helps explain why Mars has such a thin atmosphere. It just blew away (almost literally, solar wind contributed a lot to it).
Yes. I think I read the atmosphere would take billions of years to dissipate, whereas multicelluar life has around 700 million years left before the Sun makes it extinct. Kind of weird knowing humanity came to be only in the last fifth of life's existence on Earth.
When's the last time it rained?
For Bournemouth, I'd say probably two to three weeks ago.
South London, we had a light shower that lasted an hour about two weeks ago. Some of the tarmac driveways on our road have cracked in the heat, not known prolonged extreme heat like this before.
This is officially the most British climate change thread ever.
Grim
Country isn't built for weather like this at all.
Cool.
I wish.
Isn't the UK trending wetter since the mid 20th century? Making this an anomaly
I think we get warmer, wetter winters and warmer drier summers with an increase in extreme weather events in all areas (cold/wet/hot/dry). I think the wetter winters outweigh the drier summers so we get wetter on average. This is a half baked recollection so I might be talking nonsense.
Yeah you’re right. More rain and less spread through the year + longer more extreme summers. If you don’t have subsidence insurance on your house, get it yesterday.
the alternative is to stop spending trillions on global military budgets and move to clean energy generation on a mass accelerated scale. it's called "suicide" because it isn't inevitable. the means of changing the productive mode already exist. anyone not offering an economic plan centred around zero emissions and carbon capture should be disqualified from public affairs. not only killing themselves but killing everyone else, too.Sweet Jesus
In complete agreement, it's just so horrifically grim and short-sighted we (as a global population) are to this. We really should be marching the streets.
Considering that money and economics are completely artifical human inventions there really is no reason to not do what you outline here.
there is only one "war" this generation faces but so far there has been no war-like alteration in the means of production to meet the challenge. you could retrofit industrial capacity to construct everything needed to make the transformation within years. i'd argue in favour of a wartime economy if you project it over four years, or maybe five, and begin a mass industrial works program. short of that, we're probably all fecked. would also have the benefit of housing, to a clean standard, transport, to a clean standard, and a lot of jobs centred around clean re-industrialization.
has to be state mandated with sunset clauses on state authority. the private sector is too disjointed and self-interested to accomplish it. they'll make progress in isolated periods and spots, but they're competing against each other. that's the exact opposite of what needs to be happening, not to mention the profit motive which will undermine the basic premise. you can profit from the new economy, but you cannot do it until the base actually exists. and we're half a decade away from that if we enact emergency provisions.
not green new deal but renew deal.

And yet some bloke down the Red Lion called Jeff will have you believe it’s all a lie, that the climate goes in cycles 
we’ll all be alright because 1 expert scientist says otherwise, completely ignoring the many many many thousands of scientific experts that say we are heading for a disaster
with how much information there is out there, it truly baffles me there are still so many Jeffs from the Red Lion out there still thick as pig shit on the matter having blatantly done zero research other than watch a conspiracy theorist video some Moron posted on social media

I actually think it's already here and we are fecked. Everyone talking about the changes will be here in a decade and we have to act now etc.
Looking at things, I think it's here and the next 24 months are going to rapidly accelerate to a point of crisis. Lack of water, Northern European droughts, ecology collapse over summer, food shortages etc.

They need to science the shit out of this to find a solution. My suggestion to get the ball rolling would be to stop using fecking dinosaur units like Fahrenheit. Baby steps.
they need to use their military budget to enlist engineers from the army to start building mass renewable energy centres in the old industrial heartlands. those ghost cities that used to produce cars or whatever else can be retrofitted to serve as clean energy centres. massive amounts of abandoned industrially zoned land just being wasted and falling into disrepair. on top of that, consider irrigation canals in the west and mass solar projects in the south. if they move fast enough they can double their renewable capacity within a few years. china demonstrates that. america is the world's largest source of emissions per capita and only produces 14% of its electricity through renewable. china produces 25%, india 18%, canada 65%, germany 50%, and the uk 33%. of all the major economies only south korea has a worse record at 2%. even russia produces 17% from renewable. and america is the world's most advanced technological economy so that figure is a joke. they could and should be at 40-50% production by renewable by now but the corporate takeover of the state and the government's general lack of will or capacity to do anything has hampered them. biden's new bill is the first promising sign. china will be at about 70% before america is at 50% imo, they already represent more than half of all global renewable spending. plus america has favourable geography. could do mass windfarms across the coastal areas, geothermal in the central areas, solar in the southern, and hyrdogen basically everywhere.
