The reliability and accuracy of land ans sea surface temperatures are reviewed. Land near-surface measurements are contaminated by the urban heat island effect. They suffer from poor distribution, and poor maintenance in many regions, and unexplained adjustments. Sea surface temperatures before 2000 were from ship records on major shipping routes, so they have very poor coverage in the southern oceans.
