Volcanic Eruptions – When sulphur and ash is spurted out the vent during the eruption, they rise high into the atmosphere and reflect heat from the sun, having a cooling effect. We should stop wasting our money preventing CO2 emissions which have little effect on the climate, allow them to develop their economies as we did using whatever resources they want and help mitigate whatever climate change (warming or cooling) results from predominantly natural causes.
