GMST reconstructions scientific goals

*This project is now finished/concluded*

The key questions that we wanted to address were:

How did global mean temperatures evolve during the last 2000 years?

What confidence can we have in statistical reconstructions of global mean surface temperatures (GMST) using state-of-the-art methods?

Over which periods can we reliably reconstruct GMST?

What are the key similarities and differences of GMST index reconstructions based on a wide range of techniques?

 

What we aim to improve: “Spaghetti collection” of GMST reconstructions presented in the 2013 IPCC record (IPCC, 2013).
