Dit is waar het allemaal begint…Dit is ook waar het 5de IPCC-rapport mee begint. In het voorwoord van het rapport staat dat de IPCC nu 95% zeker is dat menselijk handelen de belangrijkste oorzaak is van de huidige opwarming van de aarde. Deze kaart kan gezien worden als de oorzaak van alle kaarten van de economische sector (Industrie, Gebruik van gebrouwen, Transport, Landbouw) of als heading voor deze vier kaarten (die dan gegroepeerd en omcirkeld kunnen worden.)
4Consequences
accounts for 40% of greenhouse gas (GHG) emissions
accounts for 20% of GHG emissions
accounts for 15% of GHG emissions
accounts for 25% of GHGs if we include induced deforestation.
2Other possible causes
It's the final loop of the Club of Rome. All this will eventually regulate itself, but not necessarily peacefully. The players often make this link and sometimes propose to roll up the Fresk to connect the beginning and ending edges. Moreover, it is noteworthy that humankind appears in the first and last cards, but not in the middle of the Fresk.
What comes first? Do human activities cause the use of fossil fuels or do fossil fuels ensable human activities? Don't waste time on this and group the two cards together if necessary. Plenty of activities, happily, do not require burning fossil fuels, like windmills and watermills grinding grains for flour.
3Other possible consequences
Humans occupy almost all available space on Earth, leaving no room for animals and plants. This entails the disappearance of natural habitats and it is the main cause of biodiversity loss today, well ahead of climate change.
With this link, we highlight all the degradations that humans are inflicting on marine life such as plastic pollution and overfishing. It's irrelevant to climate change, but it's interesting to make the connection anyway.
Deforestation can be considered either as a human activity, or as a consequence of agriculture, or both.
