Talking Points Against Man-Made Climate Change

Skeptic Arguments What the Science Says
"Other planets are warming" Mars and Jupiter are not warming, and anyway the sun has recently been cooling slightly.
"CO2 lags temperature" CO2 didn't initiate warming from past ice ages but it did amplify the warming.
"It's cosmic rays" Cosmic rays show no trend over the last 30 years & have had little impact on recent global warming.
"It hasn't warmed since 1998"

Every part of the Earth's climate system has continued warming since 1998, with 2015 shattering temperature records.

"There is no consensus"

97% of climate experts agree humans are causing global warming.

"It's the sun"

In the last 35 years of global warming, sun and climate have been going in opposite directions

"Climate's changed before" Climate reacts to whatever forces it to change at the time; humans are now the dominant forcing.
"It's cooling" The last decade 2000-2009 was the hottest on record.
"It's freaking cold!" A local cold day has nothing to do with the long-term trend of increasing global temperatures.
"Mars is warming"

Mars is not warming globally.

"Jupiter is warming" Jupiter is not warming, and anyway the sun is cooling.
"Pluto is warming"

And the sun has been recently cooling.

"Mt. Kilimanjaro's ice loss is due to land use"

Most glaciers are in rapid retreat worldwide, notwithstanding a few complicated cases.

"Polar bear numbers are increasing" Polar bears are in danger of extinction as well as many other species.
"Extreme weather isn't caused by global warming" Extreme weather events are being made more frequent and worse by global warming.
"Temp record is unreliable" The warming trend is the same in rural and urban areas, measured by thermometers and satellites.
"Arctic icemelt is a natural cycle"

Thick Arctic sea ice is undergoing a rapid retreat.

"It's microsite influences"

Microsite influences on temperature changes are minimal; good and bad sites show the same trend.
