Climate - truthful information about climate, related activism and politics.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

stabby_cicada made an interesting comment on how personal choice and leading by example can be combined with politics to effectively address climate change. This is a good article that combines the two approaches, it shows you some changes you can make along with reminding people the importance of voting, and being involved politically. The article mentioned the biggest user of fossil fuels in homes may be a gas fired furnace so if it's time to replace your furnace you may want to consider an electric heat pump.

One thing not mentioned in the article is if you have any incandescent light bulbs that receive regular use consider replacing them with LED. The payback period can be pretty fast for example if you replace a 60w light with a 10w LED assuming you use it for an average of two hours a day and you pay $0.20 kw/h you'll save $7.3 per year. This was calculated as follows:

(60 energy usage of old bulb - 10 energy usage of new bulb) * 2 hours per day average usage * 365 days in a year / 1000 to convert from watts to kilowatts * 0.2 cost per kwh = $7.3.

Over a 10 year period that's $73 in savings.

If the light bulb cost $2.5 to buy you'd break even in only 125 days (a little over 4 months) if we use the same usage assumptions.

Payback period can be calculated like this:

$2.5 cost of light bulb/(50 our energy savings*2 hours of average use)*(1000kw /0.2 price per kwh)

For less than a pair of airpods you can buy an electric stove and heater. That'll get you 90% of the way

You can, but they're very inefficient. A heat pump is significantly more efficient and can also keep you cool in the summer if necessary

Absolutely true, but not as cheap. I'd absolutely use one if I had the option tho. An electric heater is easier to put in a rental apartment

[–] boonhet@lemm.ee 1 points 3 days ago (1 children)

Fair enough - but then in a rental apartment, I wouldn't use electric either because usually the heating bill for central heating is calculated by apt size for everyone rather than usage, so I'd end up paying twice over. Newer buildings can have individual measuring devices which changes things.

Ye, same for mine. I just told the landlord I won't be using the gas heater. It's up to him to prove otherwise
