Favourite climate myths by Joe Bastardi

Below are many of the climate myths used by Joe Bastardi plus how often each myth has been used.

Climate myths by Bastardi What the Science Says Usage
"It hasn't warmed since 1998"

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

2
"Human CO2 is a tiny % of CO2 emissions"

The natural cycle adds and removes CO2 to keep a balance; humans add extra CO2 without removing any.

2
"It cooled mid-century" Mid-century cooling involved aerosols and is irrelevant for recent global warming. 1
"Trenberth can't account for the lack of warming"

Trenberth is talking about the details of energy flow, not whether global warming is happening.

1
"It's Pacific Decadal Oscillation"

The PDO shows no trend, and therefore the PDO is not responsible for the trend of global warming.

1
"There's no correlation between CO2 and temperature"

There is long-term correlation between CO2 and global temperature; other effects are short-term.

1
"Global warming stopped in 1998, 1995, 2002, 2007, 2010, ????"

Global temperature is still rising and 2010 was the hottest recorded.

1
"Soares finds lack of correlation between CO2 and temperature"

Soares looks at short-term trends which are swamped by natural variations while ignoring the long-term correlation.

1
"It's the sun"

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

1
"It's cooling"

The last decade 2000-2009 was the hottest on record.

1
"It's the ocean" The oceans are warming and moreover are becoming more acidic, threatening the food chain. 1
"CO2 is just a trace gas"

Many substances are dangerous even in trace amounts; what really matters is the total amount of CO2 in the atmosphere.

1
"We're heading into cooling" There is no scientific basis for claims that the planet will begin to cool in the near future. 1
"Roy Spencer finds negative feedback" Spencer's model is too simple, excluding important factors like ocean dynamics and treats cloud feedbacks as forcings. 1
