"Scientific evidence for warming of the climate system is unequivocal."

2019 was the year the world burned...

Climate change is not solely responsible for extreme weather events, but it fuels more frequent and intense episodes. Hottier, drier climates cause water to evaporate quicker, creating drought-like conditions. In 2019, these conditions exacerbated massive wildfires and sparked heatwaves.

Australia is still recovering from its most destructive bushfires in decades (pictured). The Arctic suffered its worst wildfire season, burning at an unprecedented scale. In summer, Europe was seared by record-breaking temperatures and heatwaves.

... and drowned.

Climatic impacts on extreme weather events do not stop there. A greater rate of evaporation means that more moisture remains in the atmosphere. When that uncommonly large amount of moisture is released as heavy rainfall, it raises the risk of floods.

Warmer waters also strengthen

hurricanes. Hurricane Dorian (pictured), which devastated the Bahamas, was intensified by ocean waters well above average temperatures.

We are experiencing - and are responsible for - the Earth's sixth mass extinction.

Extinction has typically been regarded as an inevitable consequence of evolution, but the rate of species extinction is now as much as 100 times the normal rate.

This expedited rate of extinction has been precipitated by extractive and pollutive human activities, which have altered ecosystems in unprecedented ways.

Due to anthropogenic (human-caused) climate change, essential pillars of nature are now at risk of collapsing.

 

If we push natural ecosystems past certain thresholds (also known as tipping points), we may trigger a worsening spiral of climate change.

We are fast approaching ecological "tipping points".

These catastrophic events are happening in a world only warmed by 1⁰C.

Even if all current pledges by governments are fully met, we are still projected to see a rise of 3⁰C. More has to be done.

The Carbon Clock

The Mercator Research Institute on Global Commons and Climate Change's (MCC) Carbon Clock has been developed in line with the IPCC's 2018 Special Report on Global Warming of 1.5°C

 

The Carbon Clock shows how much carbon dioxide can be released into the atmosphere to limit global warming to a maximum of 1.5°C and 2°C.
