Efforts to highlight the significant dangers of global warming do not
seem to be successful. Levels of atmospheric carbon dioxide (CO2), the principal cause, have combined with methane (CH4) and nitrous oxide (N2O) to speed the increase, despite decades of warnings. Global
temperatures are rising, scientists are desperately trying to focus
our attention on the seriousness of the problem, and despite
international pledges, national targets, corporate promises and
individual efforts, little of significance has been accomplished.
Significant strides in renewable energy sources have been made,
however much of this added power is not replacing fossil fuels but
supplementing them. The International Energy Agency has predicted that oil consumption could peak about 2030. We have made some progress by averting the worst of the worst future climate possibilities. But humanity has now surpassed the 1.5°C first target of temperature rise proposed in the Paris Agreement of 2015, and the pre-eminent American climate scientist, James Hansen, was prescient enough even a year ago to declare the 2.0°C target “dead”.
