Medieval Misinformation
"Earth was considerably warmer during the Roman Warming and the Medieval Warming"
This is simply false. Every peer-reviewed millenial temperature reconstruction shows current temperatures hotter than during the Roman and Medieval periods.
The 1934 Myth
"The hottest records in the USA and Greenland were in the 1930s due to a strong solar cycle."
First of all, the USA and Greenland are not the world. The global surface air temperature iscurrently approximatley 0.6°C hotter than it was during the 1930s. Secondly, today's temperatures are hotter than the 1930s even in the USA and Greenland.
Mid-Century Cooling
"It became cooler from 1940 to 1970. This was due to a weak solar cycle."
The mid-century cooling was not caused by the Sun. In fact, solar activity increased slightly between 1940 and 1970.
