“Carbon emissions down nearly two-fifths since 1990.” – or not.

 

A recent article by Carbon Brief  Analysis: Why the UK’s CO2 emissions have fallen 38% since 1990 has generated headlines:

Energy Voice: Carbon emissions down nearly two-fifths since 1990
Business Green:  UK carbon emissions down 38 per cent since 1990
Engineering and Tech: UK’s carbon emissions dropped by 30 per cent since 1990

Rejected comments

Occasionally I have a comment on another blog rejected. This will be a list of those I want to follow up.


London Economic 11th January 2019

Working people shouldn’t pay price for political failures of Conservative politicians

My comment:

To save the climate degrowth is needed.
(Kaya identity & etc.)

Subsidise the wages of the low paid.
http://www.brusselsblog.co.uk/a-macroprudental-proposal-for-employment/

Take from the rich to give to the poor.
(It’s the right thing to do.)

The rich most responsible for greenhouse gas emissions.
(So fine them and give to the poor.)

Question: does London Economic reject

1. Degrowth

2. Labour subsidies

3. Robbing the rich

4. Tax rich polluters

Or did I overdo the links to one of my own blogs?

I’m keen to find out – I rather like London Economic.



Global Warming Comes to Your Town

Open Mind

Like most people, I live on land, not at sea. I even live in the northern hemisphere.

Global warming isn’t the same everywhere. In particular, it’s happening faster on land areas than over the oceans. While the globe as a whole is warming at a rate of around 1.7 to 1.8 °C/century over the last several decades, the land areas alone have been warming up more than 50% faster, at about 2.8 °C/century. And of course, not all land areas are warming at the same rate either. On the whole, the northern hemisphere land is warming faster than southern hemisphere land; here in the north we’re heating up at around 3.2 °C/century (for land areas, I like to use the data from the Berkeley Earth Surface Temperature project).

Heat Wave 2040

Open Mind

Some things deserve repeating.

One of those things, which happened to come up in conversation recently, is that climate change has its most profound effect on extreme events. Climate change is a change in the probability function (the odds for each possible outcome) of weather, and when you look at probability functions you find that if they change in the way we expect them to, it can increase (or decrease) the chance of extremes by a surprising amount.

Capture CO2 under your new house

An idea for capturing CO2 & storing
heat under your new house

Question: “Is it a good idea or barmy?”

A heat store to capture CO2

P1. Store 50+ tonnes of rock that absorbs CO2 under (or near) a new house.

The mineral olivine is taken as the example for this note. It absorbs CO2 slowly at ambient temperature (25°C) but much faster at a temperature of 186°C. Continue reading Capture CO2 under your new house

An idea for storing renewable energy (2012)

‘An idea for storing renewable energy’
was first posted on ccq.org.uk, 25th March 2012

Question “Is it a good idea or barmy?”

Points:

1. There are times when renewable energy cannot be used. Sources tell me that 20% or more of wind energy is grounded (i.e. thrown away) because sometimes the generated energy cannot be used. Other renewable sources (solar, wave power) are also intermittent. Biomass is an exception. Continue reading An idea for storing renewable energy (2012)
