Climate Change: Lessons for Our Future from the Distant Past

We consider information from many sciences bearing on the causes and consequences of climate change, focusing on lessons from past mass extinctions of life on Earth. The increasing atmospheric levels of the main greenhouse gases are now established, as is their source in human activity. Worldwide temperatures are rising on a high variance stochastic trend. Evidence from the past 500 million yea...

Global warming and South Indian monsoon rainfall—lessons from the Mid-Miocene

Precipitation over India is driven by the Indian monsoon. Although changes in this atmospheric circulation are caused by the differential seasonal diabatic heating of Asia and the Indo-Pacific Ocean, it is so far unknown how global warming influences the monsoon rainfalls regionally. Herein, we present a Miocene pollen flora as the first direct proxy for monsoon over southern India during the M...

Nerve agents: Lessons from the Iranian experiences

On September 22, 1980 Iraqis attacked Iran's air bases and simultaneously entered Iran with six army divisions on three fronts and occupied a vast part of Iranian territories. At that time, Iraqis did not have chemical warfare. But in time, they began to develop an intensive research program to produce and store chemical weapons and used the war fields to test and perfect their chemical warfare...
