¶GROUP @35C3

Vedran, hackerspace in Zagreb, considering something climate change
Torsten, app dev,
Till,
Matthias, designing smart and green cities
Niels,
Stephan, PDH in math, believes a big challenge is to get people to care more
Lars, Computer Scientist; Energy Systems, IT-Sec, etc. (lars@larsipulami.de)

¶Temperature increase
We count the average increase in degrees since the industrial area.
Start at ~ year 1850
+ 0,9 degrees.
Debate about 1,5°C or 2°C :
* is political for one part
* is seen as the line between "normal" and "catastrophic" climate change.
* we need to keep the increase below 2°C
The assumption is this is a tipping point, for example Greenland melts, and the main ocean currents stop.
The whole world system will be out of sync.
This treshold is not set in a very scientific way:
* Since humans exist, the ossilations the planet has seen, are about 4°C
* so we take the middle of it
* it also happens to be the point where our predicting models break.
In politics the numbers matter:
* for small Islands an increase of 0,5°C it is the difference of a draught every year or 3 years.
-----discussion-----
* Stephan: the last ice age was just 5°C colder.
* Till: is this as existential threat?
Stephanie does not think so directly.
BUT climate change is also a disturbance to society:
* where people live
* where food comes from etc.
Lars points out that extintion events are not unknown in the earth's history. Recommended read "The Ends of the World" by Peter Brannen, entertaining in a morbid way

¶Climate change seen as a multiplier
The more climate change, the bigger the problem becomes
Pessimistic perspective on the loss of ressources that will create:
* violence, wars
* have a huge societal imlpact
* destroy the system we know
Max; has a more pessimistic opinion:
* because there are other tipping points where species can't move anymore
* Like a tree that blossoms, the seeds land in a different climate zone...

¶Emissions origins
33% global emissions from deforestation / land use
- land use because you can create fertilisers and they use greenhouse gasses
10%, related to special inustrial gases (not Co2)
50% energy,
- electricity
- transportation
-heating

¶Greenhouse gases (6 of them)
CO2 (burning trees+fossil fuels),
Methane (extraction of fossil fuels, lifestock emissions),
N2O,
HFCx,
Perfluorcarbons,
NF3

¶Is living in cities less impactful ?
Consider transportation, access to ressources, sharing infrastructures...

¶"Civilization as problem"
"only ever since humans moved from Africa they created an impact on Earth"

¶ * Measure your own CO2 footprint
BECOME AWARE OF YOUR IMPACT TO CHANGE HABITS
how ?
what tools to use ?

¶ * Financial investment is needed
THIS CHANGE (and the situation) IS NOT FOR FREE:
we have to be willing to pay for the consequences
or to pay for the necesary changes
Costs are on individuals for an impact at a greater scale of the society.
It will pay back for the collective
i.e. if we invest in reducing atmospheric pollution as individuals there will be less costs in health to treat lung diseases for the society

¶ * Change your transportation habits
STOP FLYING !!!
take trains and boats
- for the next COP in Chile.
- you can work in trains (computer, softwares available, hotspots, ...)
DON'T USE CARS
yes in cities, how about people in countryside ?
general change needed with remote working places, better transportation networks...

¶ * Adopt a vegetarian diet
EATING MEAT IS NOT ECONOMICALLY NOR ECOLOGICALLY EFFICIENT !!!
no animals = less land for animals, less land used for animals food

¶ * Consume less
DON'T BUY SO MUCH
REDUCE YOUR ENERGY CONSUMPTION
ie:
* reuse and upcycle
* house heating is a huge part for individuals
* buy used hardware
* [...]

¶ * Create / Use green energy
with your own energetic installation
(controverse on buying new "eco" things...)
by choosing a different supplier

¶ * Consider not to have children (taboo)
This is a controversial point !!!
It deals with birth control, control of population...

¶Idea by mathias: "things to do for a sustainable living" website
Mathias: I'm thinking about creating a website with "things to do for a sustainable living". The site has a list of things everyone can do to reduce the CO2 footprint. On the website, users see a long list of things to do, with a filter for "impact on CO2 footprint", "expenses required", "level of complexity", and "area of living" (e. g. energy, transport etc.).
Things can be added via Github, which is deployed to a website, so everyone can extend it with projects of their own experience.
For this, we need a reasonable number of people that are willing to start a prototype of it. Who would be in? Who knows a similar website we maybe should rather contribute to?
There would be a how to congress more sustainible, for example:
- Drive by train
- Organise driving together in one car
- bring your prepared food in reusable boxes
- eat more vegetables, whole grain and fruits
- sell or give away your old hardware to others
- use hardware as long as possible
- repair and upcycle things
