I go into my kitchen and I look at my fridge, whose job is to move heat outside of itself into the room. Centimetres to the right of it is the oven, whose job is to make heat, and we don't like using it in the summer because its whole thing is making heat. Further right is the AC vent, which is connected to a furnace downstairs, which is connected to a big fan outside which blows my heat into the neighbourhood for a few minutes each morning to dry out the air and make it tolerable with a fan. Right next to the furnace, within a metre of it, is the hot water tank, which is another inside-out fridge that takes heat from the basement and puts it into my shower water.

None of these machines are connected together in any way at all

Like, what are we doing here. What are we doing as a species.

These days, spacecraft routinely come equipped with selfie-cams ("monitoring cameras"). The Juice probe took these snapshots as it bid farewell to Earth and set course for Jupiter & its moons. https://www.esa.int/Science_Exploration/Space_Science/Juice/Juice_sends_first_selfies_from_space #Juice #Jupiter #ESA
Juice sends first ‘selfies’ from space

ESA’s Jupiter Icy Moons Explorer (Juice) has taken its first monitoring camera images showing part of the spacecraft with Earth as a stunning backdrop.The mission launched on an Ariane 5 from Europe’s Spaceport in Kourou on 14 April 14:14 CEST and the images were captured in the hours afterwards. 

It's no UFO... but always amazing to see. Early yesterday morning, the all-sky camera at Poker Flats, Alaska caught something strange along with the usual green bands of aurora - an expanding blue spiral: https://vimeo.com/818040730 - The culprit: a SpaceX Falcon-9 launch from Vandenberg three hours earlier, with the Transporter-7 rideshare launch. The spiral was the fuel vent from the discarded second stage booster, spinning and creating an ephemeral 'galaxy' in the Sun overhead.

The ever-present danger of global variables.

This terrific photo was taken by my grandfather around 1935. It shows my mother and her brother, with a small owl.

They often shared their home with injured wild birds that were being rehabilitated by their father. Mergansers or storks in the bathtub where not unusual.

Those birds that didn't survive were stuffed, used in teaching, and for many years afterwards were on display in the local museum.

I don't know the fate of this owl, but most survived & were released. #bird #birding #owl

Oxygen production seems to be roughly evenly split between terrestrial and aquatic sources, despite the terrestrial domination of biomass. Terrestrial plants have a lot of woody growth which is not very productive. I would love to see a graph of oxygen production/consumption by species type - I suspect mammals/birds would be more strongly represented as consumers and cyanobacteria as producers. The source for all this data is here, an interesting and short read: https://www.pnas.org/doi/epdf/10.1073/pnas.1711842115

The wikipedia article on Biomass is fascinating. This graph in particular. Terrestrial plants outmass all other organisms on Earth 100-1. Terrestrial fungi outmass humans 100-1. Humans biomass is about equal to insect biomass and earthworm biomass. Human made materials outmass all biomass on Earth.
