We’ve listed the facts of global heating, environmental degradation, and climate breakdown below in order to present a short-but-shocking imperative for action against these issues. This can also act as a factsheet that climate activists can pull from to help with any of their projects or in any of their circumstances.

We will be adding to this list as new facts present themselves.


  • Global heating is a scientifically-proven fact, which 97% of accredited scientists agree upon. It is also known that this issue is caused by human activity. Here is a statement from NASA regarding this consensus.
  • Climate breakdown will not eventually hit us in the future – it is hitting us now. Between 2000 and 2007 we have had 17 of the hottest 18 years recorded since 2018 – this is no coincidence. The effects of man-made climate breakdown include more powerful and more frequent extreme weather events, which encompass all things from droughts, flooding, hurricanes, and rising sea levels. Read about the effects here.
  • We need to take drastic action to try and limit the rise of global average temperatures by 1.5C which will limit the damaging effects of the increase in temperature. Read the 2018 IPCC report on the 1.5C limit here.
  • Annual global emissions have increased by around 31 gigatonnes in 68 years, with global average temperatures increasing by 1.2C since 1850. Click here for a report on CO2 and other greenhouse gas emissions.


  • There is a 1 in 20 chance that climate breakdown is an extinction-level threat. The 2.2 trillion tons of carbon dioxide in the atmosphere could be our downfall.
  • To effectively combat climate breakdown, we need to:
    – Reduce our global CO2 emissions to net zero by 2050.
    – Limit super-pollutants such as HFCs and methane.
    – Remove carbon dioxide from the atmosphere.
    – Radically change the global food industry and limit meat production.
    – Divest in fossil fuel conglomerates and invest in renewable green energy.

  • The chance of a ‘Hothouse Earth’ is still high. Even if the Paris Climate Agreement is acted upon and we keep global temperature increase to 1.5C, climate feedback systems could act against us, making the cycle of global heating irreversible. Click here for a report by PNAS on feedback systems.
  • US$320 Billion worth of damage was caused in 2017 as a result of climate-related disasters, with this number expected to rise.
  • Extreme weather events represent the greatest risk to the future development of humanity, according to the World Economic Forum’s 2018 Global Risk Report.
  • The pH level of the oceans is becoming more acidic. The oceans alkalinity has decreased by 30%, and is projected to decrease by 150% by 2100. We have not experienced a pH level like the one we have today for more than 20 million years.
  • Humanity has wiped out 60% of mammals, birds, fish and reptiles since 1970. Read the WWF report on this loss here.
  • 7 million premature deaths per year are caused by ambient and household air pollution. 
  • Fossil Fuels are propped up by an estimated US$373 billion in subsides and tax breaks, according to the OECD.
