<p>Relief of iron (Fe) limitation in the Southern Ocean during ice ages, with potentially increased carbon storage in the ocean, has been invoked as one driver of glacial–interglacial atmospheric
<p>Fossil fuel CO2 emissions in the United States decreased by ~11% between 2007 and 2013, from 6,023 to 5,377 Mt. This decline has been widely attributed to a shift from the use of coal to natural
<p>Climate strongly influences global wildfire activity, and recent wildfire surges may signal fire weather-induced pyrogeographic shifts. Here we use three daily global climate data sets and three fire
<p>This new study led by an Indian scientist Dr Roxy Mathew Koll, from the Indian Institute of Tropical Meteorology (IITM) Pune, points out a significant decreasing trend in the summer monsoon rainfall over the central Indian subcontinent during the past century. It suggests an important role of the rapid warming in the Indian Ocean in weakening of monsoon circulation and rainfall.</p>
