1. INTRODUCTION

Has the IPCC exaggerated adverse impact of Global Warming on human societies?

Yes, Certainly! Let me explain: While reviewing the IPCC WGII (Working Group
II) Chapter “Assessment of observed changes and responses in natural and managed
systems” (Chpt.1, WGII IPCC, 2007) as an external reviewer, I felt time and time
again that there were areas where the chapter authors highlighted adverse impact of
GW (Global Warming) on human societies, while downplaying possible beneficial
impacts. The IPCC authors referred to several publications which projected adverse
impacts while ignoring many excellent studies which have questioned these
projections.

Throughout the text of this important chapter of WGII, there were many
instances where adverse impact was highlighted or exaggerated, while possible
beneficial impacts were totally ignored. Further, IPCC authors while assessing
observed changes in natural systems chose to highlight only those changes which
support the GW hypothesis while completely ignoring other observed changes which
did not conform to the human-induced GW hypothesis and change. Such cherry-
picking of observed climate change to bolster claims of human-caused GW and
climate change is disingenuous and does not help understand the real cause of how and
why the earth’s climate has changed in historical and geological times.

A detailed reading of the Chapter left me with an impression that the deleterious
impact of GW on human societies was so imminent and overwhelming that unless
something is done right away (to curb the warming), human societies world over are
about to perish!
