Sentences with phrase «temperature reconstructions»
"Temperature reconstructions" refers to the process of determining past temperatures using available evidence. It involves collecting data from sources like tree rings, ice cores, or historical records and analyzing them to estimate what the temperature was like in the past. This helps scientists understand how temperatures have changed over time and can provide insights into climate patterns and trends. Full definition
Although temperature reconstructions from proxy data help us understand the character of natural climate variability, attribution of recent climate change relies on a broad range of methodologies in addition to the proxy reconstructions.

There has been a considerable advance in understanding of temperature change that occurred over the last millennium, especially from the synthesis of individual temperature reconstructions.
For this reason, it is widely acknowledged by scientists that tree - ring data are not reliable after 1960, and therefore should not be used for temperature reconstructions after that date.
Although temperature reconstructions from proxy data help us understand the character of natural climate variability, attribution of recent climate change relies on a broad range of methodologies in addition to the proxy reconstructions.
