Gabriele C. Hegerl

From Wikipedia, the free encyclopedia

Gabriele C. Hegerl is a coordinating lead author for the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report.

She is a researcher at Duke University's Nicholas School of the Environment.

She led a team that claims to have:

... found substantial ups and downs in the Earth's temperature before modern times, countering other studies that confine noticeable temperature increases to the industrialized era. Marked climate change in other centuries resulted from "external forcing," said the Duke findings, citing volcanic eruptions and other influences. "Our reconstruction supports a lot of variability in the past," said research director Gabriele Hegerl of Duke's Nicholas School of the Environment and Earth Sciences. [1]

However, Hegerl has also led well known research on the attribution of modern climate change to anthropogenic greenhouse gas emission. She is a coordinating lead author on the IPCC Fourth Assessment Report for Working Group I in the chapter on "Understanding and Attributing Climate Change". [2]

Research is the natural variability of climate and changes in climate due to natural and anthropogenic changes in radiative forcing (such as greenhouse warming, climate effects of volcanic eruptions and changes in solar radiation).
