The Science Behind Climate Change

We talk to Professor Andrew Holmes talks about the science of climate change.

“…human-generated carbon dioxide emissions are imposing on the planet an unsustainable burden in terms of temperature increase. And we must address that”. Andrew Holmes (2018)

Human Activities

Energy production and its by-products play a central role in global warming and cooling. Fossil fuel combustion is the biggest cause of increased CO2 atmospheric concentration.

It is almost unanimously agreed that human-caused global warming is real [1]. “Continued reliance on fossil fuels would lead to greater impacts in the future…”.

It is estimated that carbon dioxide concentration will continue to rise at an alarming rate if left unabated. By the year 2100, global warming may lead to a global temperature increase by as much as six degrees Celsius.

If we can shift away from the reliance our mains sectors place on fossil fuels and preserve our remaining fossil fuel reserves then that will go a large way in combating the predicted growth in warming for the coming decades.
