According to a recent presentation by climate scientist Dr. Ole Humlum published in Science of Climate Change:

Real-world observations show both cooling and warming trends in the Arctic, Antarctic, and Tropical oceans since ARGO monitoring was introduced in 2004.

Real-world observations show no trend in global precipitation since 1979.

Real-world observations show global cloud cover decline since 1985. A decline in cloud albedo means more solar radiation can be absorbed by the surface. Thus, the decline in cloud cover can easily explain the warming of the last 40 years.
