Maybe I’m an idiot but how does “mm per year” classify you as being at a high risk of sinking? Seems a lot different depending on your elevation. The highest peak could sink a meter per year and still not be at risk of flooding

True, for not being at risk from flooding from the ocean given elevation (from sea level).

Local flooding: entirely possible. For example, over a few years city X sinks by a cm, because of that in a flood situation there's slightly more flood water. Over a large area that might be quality a few acre-feet of water: that's quite a lot more water.

It's less that the likely hood of a flood increases and more that the severity of a flood increases.

the circle is the city location, not the tip of the cone, for anyone else who was confused

LOL @ Seattle....

yeah, bits will be underwater one day. thank goodness most of the town is up on giant ridge lines and hills.

yeah, ima need to see the methodology dawg

I suspect the Houston number is actually Katy or the gre at Houston area as a whole because last I check Houston-proper has taken some action to reduce the pumping of ground water and mostly stabilized? But the surrounding suburbs think not wanting flooding is commi BS probably.

I know you refer to the credit card comparison but right at the top it literally says "mm/year".

How much is that in milli-school buses?

[-] nocturne@slrpnk.net 2 points 1 month ago* (last edited 1 month ago)

If we use a bus at 45' and convert that into milli-school bus you get 0.045 feet = 1 milli-school bus. 1 milli-school bus = 13.761mm.

1 mm = 0.00328084 milli-school bus

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.
