Though to be fair, waiting for proof of climate change means it's far too late by the time the evidence is there.

 

far too late for what ?
We will cope. The earth wont melt .
Humans have lived through major climate changes in the past
The Earth has had periods far far warmer than now , it wasnt a catastrophe , life went on .

 

 

 

 

 

 

Correct. Nature and the natural gases in the atmosphere equalised over time and evolved to warmer and cooler periods. Volcanoes erupt then stop erupting, wildfires burn and go out. The meteor of 67 million years ago covered the planet in ash, it went cold, and that dissipated over time. But those periods didnt have artificial and continual emissions added as we are doing. And we have only been doing that for 200 years and that's spiked hugely in that chronological blink of an eye

The fact that I can keep cool in the summer is pure bonus ๐Ÿ˜€



That's a complete waste of electricity and not 'green' at all. I never use my heat pumps for cooling.


Open the windows or poke up with it.


 



No way. It's no more a waste than using them for heating. Less in fact as most heat pumps are more efficient at cooling.

Our ducted system runs 24/7 365 days. What's the point of modern conveniences that you don't use?!

I'm thinking of getting a ducted heat pump system for part of our house next year. Any issues/drawbacks I should be aware of?

 

I was originally thinking of a ground source heat pump system but cost and installation inconvenience has put me off somewhat.

I really recommend them. Ours was installed by the local Fujitsu agent who came and surveyed the house to calculate the correct unit required etc. There's no noise from the system at all and the control software (Airtouch) is an iPad like device on the wall that shows the temperature in each room, the set temperature in each room, which rooms are turned on or off etc etc. It controls air flow and damper opening fully automatically.

The whole house just sits at whatever temperature you set. Ours is mostly 18 with the bedroom usually 17. It's a boon to walk in when it's warm and humid to a house with cool, comfortable environment. Sleeping is so much better too.

Certainly from the planet's point of view, climate change is neither good nor bad. It's just something that happens. But major climate change has huge economic and social impact on humans. Human activities are very heavily optimised for the current climate... ports are at current seal levels, a lot of housing is just above current sea level, as is a lot of infrastructure like roads, railways, and airports. Flood containment mechanisms are sized for the current climate. Houses are built for current wind loads. Farms are in temperate climates.

 

The longer we delay in managing climate change, the worse the effect is going to be, and the more it will cost to cope with it. The crucial point is where the cost of adapting to/repairing the effect of climate change exceeds the cost of preventing it. That's what we're too late for.

 

Yes, the Earth has been far warmer than now, and life went on, and in fact climate change was great for the creation of current species. But it *was* a catastrophe for species which couldn't adapt to the warmer (or colder) temperatures. One of the ways that humans lived through climate change in the past was to simply migrate to somewhere with a more acceptable climate. That wasn't a problem when the entire population was a few million and there was plenty of spare land and infrastructure consisted of mud huts, but it's not a great option nowadays. As indeed we're seeing with the flood of refugees trying to get from Central America to the USA, or Africa to Europe.

I think the proof for climate change is convincing.  However, the trend to attempt to link all adverse weather events to climate change is unbalanced and unhelpful.  When there is a run of pleasant weather, no-one ever mentions climate change.

 

I'm an independent reviewer for research proposals for a couple of funding organisations.  I still see lots of proposals to measure/prove climate change. That work is now bordering on redundant, and committees are starting to score such proposals low on 'novelty' and 'benefits'.  Whereas proposals to develop solutions and adaptation are viewed much more favourably.

Yep. And as far as adapting goes, all life forms will adapt, either by location or physiological changes. But thats over a LOOOONG time, not 200 years.

Life has endured sudden deleterious events before.  Volcanic eruptions, massive meteor strikes, snow-ball earth (google it).  Climate Change strikes me as humanitarian, political and economic problem.  Ecologically, the planet will bounce back fine after we have eradicated ourselves.

Yes, it will bounce back, assuming that it doesn't get into a cycle of warming as Venus did, a runaway effect

You mean that planet exactly like earth except for being 40million km closer to the Sun, with an atmospheric pressure 30 times greater, no magnetosphere, an orbital period equal to its rotational period (so same side always faces the Sun) and an atmospheric composition that is almost 100% CO2 (Earth’s is 0.042%)?

So earth won't become another Venus. It still could become less of an earth.

You mean the ones that adapted?

 

Killed animals for food and clothing and burnt stuff to stay warm?

 

Just have a look around at all the adaptions to your current climate that a high energy society has produced. What produced the roof over your head? The chair you are sitting in? The clothes that you are wearing that were produced half a world away and transported here so you could be kept warm and dry outside, or protected from the Sun.

LOL ok!

 

No

 

Mercury is far closer to the Sun. Venus is a greenhouse gas example. Where did the "atmospheric composition that is almost 100% CO2" come from?

 

Earth. Artificially created greenhouse gases, not from nature. A decade or more ago, they can puncture the tundra, light a match and get flame. Most of the Russian tundra (frozen dirt) is barely above freezing. Thats a pure methane source. Melt off the Arctic and Antarctic sheets and you get less reflection and more absorption. In time the oceans will have less disparity between hot and cold, less ocean current movement, less oxygen in the seas, life dies, decomposes adding more gases. Its a cycle. 

 

But hey, maybe its fake news like Covid..... Inconvenient.
