"It's the sun"

This is wrong because in the past 35 years the sun has shown cooling trend. Sun and climate have been going in opposite directions. In the past century, the Sun can explain some of the increase in global temperatures, but a relatively small amount. The sun haves a engery the fluciates for 11 year long cycle.In recent times the biggest solar fluctuation happened around 1960. But the fastest global warming started in 1980.

2) "It's not bad"

This not correct because the consequences of climate change increasingly bad agte each additional degree of warming. The consequences of 2 degrees C being damage and the consequence of 4 degrees C being potentially catastrophic.

3) "It's cooling"

However, weather imposes it's own dramatic ups and downs over the long term trend. So we expect to see record cold temperatures even during global warming. Nevertheless, who hasn't heard someone on a cold day mutter "what happened to global warming? Mentally calculating long term statistical trends doesn't come quite as easy as recalling that cold morning a few winters ago or that sweltering heat wave last …show more content…

Pluto experiences drastic season changes due to an elliptical orbit (that takes 250 Earth years). Any Plutonian warming cannot be caused by solar variations as the sun has showed little to no long term trend over the past 50 years and sunlight at Pluto is 900 times weaker than it is at the Earth.

8) It's a climate regime shift"

Their research suggests our climate is subject to dramatic regime shifts. At key moments, the climate shifts from a warm regime to a cool regime, or vica versa. They claim climate shifts occured around 1910, 1940, 1976 and 2001. Some have interpreted this work to say climate shifts can explain the last few decades of global warming.

9) Renewables can't provide baseload power

Although renewable energy does not necessarily need to provide baseload power in the short-term, there are several ways in which it can do so. For example, geothermal energy is available at all times, concentrated solar thermal energy has storage capability, and wind energy can be stored in compressed air.
