The main cause of climate change is not plastic or meat. It’s energy [1,2]!
Generating energy (for heating, lighting, transport, manufacturing and more) is responsible for about 74% of greenhouse gas emissions .
Greenhouse gases are found naturally in the air and ‘trap’ heat in the atmosphere [2,3]. Without them the Earth would be covered in ice ! Take a look at our posted image!
But because humans are producing extra greenhouse gases, mostly by burning fossil fuels for energy generation [1,5,6], the Earth is becoming warmer and warmer .
Take a look at the graph we posted.
The dashed line shows how emissions are predicted to increase in the future . To limit the negative effects of climate change, the world’s governments have agreed to aim to keep global warming to no more than 2°C above pre-industrial levels, and ideally to just 1.5°C .
The green line shows that emissions need to decrease by 7.6% each year between 2020 and 2030 in order to achieve the 1.5°C goal [10,11]. Clearly, we are well off track.
Can we continue to allow emissions to increase? 11,000 scientists have signed their name to say no: we are facing a climate emergency and things have to change . So, what should we do? We’ll look at this in the next post!
