Lord Monkton of Great Britain

Skeptic

200

Some think this has an 11 year cycle and has much influence on Earth's warming climate.

The Sun

200

The year that "The Great Global Warming Swindle" was released by the BBC.

2007

200

The threshold of global average warming commonly associated with “dangerous” climate change and the target often cited in negotiations (in °C above preindustrial).

2°C above preindustrial (with 1.5°C as the more stringent aspirational target)
