Solar Influence: Observations of sunspots began in the time of Galileo, about 400 years ago. Heinrich Schwabe recognized the 11.1 year solar cycle average in 1843. Science is working to improve our understanding of solar activity but beyond 400 years it becomes increasingly speculative.

Global Surface Temperature: NCAR/UCAR, NCDC, and NASA GISS Analysis: The current analysis uses surface air temperatures measurements from the following data sets: the unadjusted data of the Global Historical Climatology Network (Peterson and Vose, 1997 and 1998), United States Historical Climatology Network (USHCN) data, and SCAR (Scientific Committee on Antarctic Research) data from Antarctic stations. The basic analysis method is described by Hansen et al. (1999), with several modifications described by Hansen et al. (2001) also included. Modifications to the analysis since 2001 are described on the separate Updates to Analysis.

Oceanic Thermal Inertia: The primary reasons we are not heating up faster include oceanic thermal inertia and industrial negative aerosol forcing.

Weather v. Climate: What is the difference between weather and climate? Weather is considered short-term variability, while climate is long-term trend based on multiple factors. These factors depend on context. In other words, one persons weather is another persons climate. Generally speaking, in the context of human caused global warming, climate is considered 30+ years of trend with attribution.
