Temperature record of past 1000 years

• The tremperature record of past 1000 years describes the reconstruction of temperature for last 1000 years on the Northern Hemisphere.
• Studying past climate is interest for Scientists in order to understand current climate variability and providing a basis for future climate projection.
• If nature and magnitude of natural climate variability can be established,scientist will be in better position to identify human generated cliamte variability.
• Although temperature reconstructions from proxy data help us understand charecter of natural climate variability,attribution of recent climate change relies on broad range of methodology in addition to proxy reconstruction.
• By far the best observedperiod is from 1850 to the present day.
• Direct thermometer readings has approximately global coverage.
• It shows a general warming in global temperature.
