Climate Change Mega Thread

Three basic ideas to reduce unnecessary radiant heat on our planet:

1 - Reduce the excessive width of residential streets. This will reduce the amount of natural vegetated land used for subdivisions (most zoning now requires on-site parking, so no need for wide streets). Existing excessively wide streets can have treed boulevards added, to shade pavement. Pavement generates massive radiant heat, whereas as vegetation absorbs heat. Narrow residential streets are also cheaper to maintain and replace.

2 - Eliminate dark colour roofs. Instead use light colours that reflect heat. Light coloured roofs reduce air-conditioning energy, and roofs will last longer.

3 - Shade buildings and pavement with deciduous trees. Leaves provide shade during summer, and sun exposure during winter. Deciduous trees naturally reduce building cooling and heating expenses, and make parking lots more natural and cooler.
.
As an experiment, place a thermometer on each of these surfaces when exposed to summer sun, and notice the extreme temperature differences: 1) Black-car/pavement, 2) White-car surface, 3) Grass.

Lower Mainland hotter than Africa today.

Must be all those NG outdoor fireplaces, burning off their part of the 92-billion-cubic-feet of NG produced every day...

A bit ironic, that California hydro-electric reservoirs are running dry, partly to supply power for EVs, so now they have to burn natural-gas to generate electricity, as wind and solar aren’t predictable supplies. As population expands, more energy will be consumed.

Weird! It must not be summer in Africa.

I am not sure if you are being sarcastic or not, but the Sahara Desert is in the northern hemisphere.

Sarcastic (you're not familiar with my posts). They don't really have seasons other than wet or dry.

Diane Francis: Canada is a giant carbon sink. Why are we not getting credit for it?

The United Nations Paris Agreement and its predecessors are a complete failure and they discriminate against Canada, which is why Canadians should demand changes immediately, or withdraw. There are two main reasons why.

First of all, the agreements exempt the world’s biggest polluters. They do not require all the countries that signed on to reduce emissions. So, of course, they haven’t: to date, of the 192 countries that signed on to the Kyoto Protocol in 1997, only 37 developed countries have reduced CO2 emissions by seven per cent and the rest — led by China and India — increased emissions by 130 per cent. This is not an accord, it’s a joke.

Ms.Mrs. Snippy above snipped off the wrong part... Jeeeesh!!!!

Secondly, the agreements measure countries based on emissions, but ignore the other side of the environmental balance sheet, which is carbon absorption and offsets. Canada only emits 1.6 per cent of global carbon emissions now, but probably would not have any net emissions if its gigantic “carbon sink” — its inventory of forests, muskeg, water and soil assets that absorb carbon — were taken into consideration.


Canada, in fact, is one gigantic carbon sink — an empty land mass with very few people and an abundance of natural features that decarbonize the world.

Heh, I originally made a snarky reply, then deleted it cause I kinda figured you were being sarcastic, just wanted to make sure. Carry on.

It is a joke. Canada will never be carbon neutral so long as the UN needs money. After 5 years and billions of dollars, nothing has been accomplished.

"you don't even have to mention green house gasses in your commitment if you don't want to, you send in any piece of paper you want, they all get stapled together and called the Paris Climate Accord."

It is really an agreement to do nothing to great hollow applause. The US did the right thing by leaving the farce/fraud agreement.

This is not climate change either, but it is in the climate change thread ;-)

Antarctic sea ice extent has been gradually growing since the chart began. Even the north arctic minimum extent for 2021 will be at least 1 million sq-km larger than 2020. Just because Antarctic sea ice continually grows, doesn't mean we believe there will be a snowball earth in the near future. It is hard to see any trend as humans since we have only captured accurate data for a few decades.

Some interesting news.

For many years the warming trend used to be 0.14C/decade. This rate has dropped since last month to be 0.13C/decade.

The linear warming trend since January, 1979 has now dropped slightly, at +0.13 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).

This is not climate change: it's just normal.

"Scientists warn glacier in Canadian Rockies is slipping away before their eyes at unprecedented rate"

https://globalnews.ca/news/8154343/cana ... cier-melt/

It's hard to believe but there are some people that actually do not know that those glaciers may not have existed at all times throughout the past. Between ice ages there have been times with no glaciers in certain parts where they exist now, let alone an ice cap at the north pole.
The last 2000 years has had many retreats, some of which were greater than the "man made" retreat of present day. Over the last 100k years there were many many retreats and advances. All without human influence.
I guess it was magic back then.
