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.

Yeah, micro mobility is great on paper when you’re young and live in an accessible city with flat topography. Years ago I became (and still am) a bicycle commuter and I am ENTIRELY SICK OF IT. I want a fucking car. I am tired of biking in the rain and the snow and the cold. It fucking sucks.

Also If I didnt have the ability to purchase an e-bike recently I’d be fucked with the terrain of the place I am currently stuck living (and even that doesn’t quite cover the situation).

Also I am tired of minor injuries compounding year over year due to the simple fact that I am using my body as both the engine and support structure to move myself, vehicle and cargo around just to live.

It was fun 10 years ago but now I’m just like give me a fucking cargo van.

I completely understand the weather thing. In the Netherlands it doesn’t get that cold, but the rain is really annoying (it rained basically non-stop from october till late february). In the city where I live however, there is also a pretty good bus service, so you can avoid cycling longer distances in the rain. For me I find cycling in good weather so good for my mental and physical health that I wouldn't want to go without it.

You say an e-bike doesn’t quite do it for you, and I'm curious what you mean. Is it that it doesn't have the range, that the engine isn't strong enough for hills, or something else? I would love to learn about more disadvantages of micromobility, so I can create more nuanced opinions.

I used to live in Boston, which in recent years has become very bike friendly and is actually setup to make sense using a bike for primary transport (fairly robust public transit for the US, physically pretty small), but now I live in a city in Massachusetts where the area has very little bike infrastructure, and the landscape is hills and valleys of hundreds of feet of varied elevation every half mile or so. Using a non-electric bike for daily errands / transport would be equivalent to running a marathon every time I need to pop over to the grocery store. The e-bike battery and range runs out so fast that i’m basically limited to a single specific errand every time I go out—no option for doing more than one thing. Also add to the fact that everything is designed around cars so amenities are not blocks away, but rather towns away.

The northeastern United States sees basically every type of weather so there are days where it’s wonderful to be out on a bike and days were it is a complete nightmare—when you have to get on your bike to get to work when its raining sheets or 10 degrees (Fahrenheit) outside and there is no other option it becomes a wretched ordeal.

My point is, beyond a very specific set of circumstances where weather, health, topography, public transit infrastructure and also the immense luxury of even being able to live in a city all line up, using a bike as a primary mode of transportation is completely useless solution.
