claim: In fact, in recent years when cosmic rays should have been having their largest cooling effect on record, temperatures have been at their highest on record.
evidence: The actual temperatures are not known, because the size of the hot spots could not be measured, but are likely to have been in the 800–1,100 K ( 527–827 °C; 980–1,520 °F ) range, relative to a normal temperature of 740 K ( 467 °C; 872 °F ).
