Energy cannot be produced or destroyed but can be transformed from one form into another.
Higher temperatures have negative effects and the higher CO2 emissions the higher the atmosphere’s temperature. We need to bring CO2 emissions to Zero if the global atmospheric temperature is to remain unchanged.
We have two choices, either stick to transport issues or go to the core of the problem namely, what it takes to containing the global warming within 1.5 degrees. The CO2 is still rising and global warming is getting worse.
As with Covid, climate change challenge should start with Challenging the UN Paris Accord Climate Emergency to contain global warming within 1.5 degrees so the challenge is clear. Now that we know what the challenge is we must start from the science based facts from which we, as Engineers, will determine the appropriate solutions. It is suggested that Engineers may identify the appropriate solutions, but governments and businesses – hopefully with the concurrence of local councils, parliaments and people – will determine the adopted solution.
