Fridays for Future

is a youth-led and -organised movement that began in August 2018, after 15-year-old Greta Thunberg and other young activists sat in front of the Swedish parliament every schoolday for three weeks, to protest against the lack of action on the climate crisis. She posted what she was doing on Instagram and Twitter and it soon went viral. It has branches in 7,500 cities, involving 14,000,000 people, on all continents
except Antarctica. See Greta Thunberg's 2018 Ted talk

is one of the most active groups in the international climate movement. Their website gives a view over climate action all over the world. The name refers to the level of CO2 in the atmosphere, measured in parts per mission (ppm) that we should aim to return to, to avoid dangerous disruption to our climate. The preindustrial level was 280 ppm, and we are now at about 419 ppm (which means we are almost exactly half way to doubling the pre-industrial level).

The Climate Reality Project

was set up by former US Vice-President Al Gore. Like, it has a first rate website. One of its most important activities is to provide training for climate activists.  

Climate Action Tracker

-- more a source of information than a campaigning organisation. It runs an authoritative website which reviews countries' efforts to combat climate change. Their world map  colour-codes countries according to the extent to which their pledged emissions reductions (their Nationally Determined Contributions, NDCs) are compatible with the Paris Agreement goal of limiting temperature rise to no more than 1.5 degrees C. The UK and Norway are the best of a bad bunch among the developed nations -- our NDCs are "almost Paris-compatible". 

End Fossil -- Occupy!

Between September and December 2022, the climate justice movement youth is going to occupy hundreds of schools and universities all over the world.
We will not give in until we achieve the end of fossil fuels era.Our Demand: End Fossil…!Our goal is to change the system by ending the fossil economy at an international level. Depending on the local context, the demands can vary between end fossil extraction, fossil finance, fossil funding, fossil infrastructures or others.
