Scientists say humans have generated 1.3 trillion tonnes of CO2 pollution since the industrial revolution.Carbon dioxide in the Earth’s atmosphere has hit levels not seen in at least four million years, with scientists warning that the effects of climate change will only worsen in Australia and around the world without swift action to curb emissions.
While NOAA started measuring atmospheric CO2 at its Mauna Loa observatory in 1958, ice core data collected by Scripps Institution of Oceanography is used to measure CO2 levels dating back to pre-industrial times. However, research by Climate Action Tracker found that despite the pledges of world leaders at November’s COP26 Glasgow climate summit, the world is on track to warm by 2.4C by 2100.Professor Mark Howden, Director of the Institute for Climate, Energy & Disaster Solutions at the Australian National University and Vice-Chair of the Intergovernmental Panel on Climate Change , explained what the NOAA figures mean.
Monash University climate scientist Dr Ailie Gallant said the observations “just adds to the body of evidence" that shows CO2 continues to "increase unabated".
Worried about climate change Everyone should have acted 20 years ago.
Co2 levels rise More heat trapped Permafrost melts Methane escapes 28 times more potent greenhouse gas Aerosols mix with methane & become 32 times more potent

Bloody freezing in Melbourne. When is this global warming thing going to kick in Getting impatient
Not as if we haven’t known for decades, but let’s just get on and deal with it.
