Media reports to the contrary, global warming is still on

Jim Wild, Lancaster University:
Recent headlines are warning that the Earth will enter into a “mini ice age” in about 20 years because the sun is heading towards a period of very low output. Here’s why this scenario is extremely unlikely.
So what about global climate change? If solar activity is falling, and that has a cooling influence over the UK and Europe, isn’t that a good thing?
Unfortunately not. The overwhelming consensus among the world’s climate scientists is that the influence of solar variability on the climate is dwarfed by the impact of increased levels of carbon dioxide in the atmosphere. Most calculations suggest that a new “grand solar minimum” in activity would have a cooling effect that would temporarily offset just a few year’s worth of the warming due to the emission of carbon dioxide by humans.
We may well be heading towards a period of low solar activity, but a new mini ice age seems very unlikely at this point.
Briefly, the last Little Ice Age was probably due more to volcanic activity than to fluctuations in solar output.
Expressing my outrage with those who twist scientific work into support for the petroleum industry’s profits is impossible without swearing.
For that matter, suppose we are going to have a Mini Ice Age. Shouldn’t we should be saving fossil fuels for when we’ll need them? But for hypocrites, there are no boundaries, no reason, nothing except their narcissistic pursuit of planetary destruction.
