Technology has revolutionized almost every aspect of our lives - from healthcare to doing business. The field of meteorology is not far behind. In a recent study, scientists have leveraged the computing power of a new series of processors from Intel, to improve existing climate models and simulations. The new models, the researchers claim, have better accuracy and increased speeds and also free up meteorologists from the hassles of computer science.

Global Climate Models (GCMs) are mathematical models to understand and predict the Earth’s climate by projecting the real-world processes over time. These simulation tools help to predict future climate variables that will be useful to develop sustainable long, medium and short-term water resource planning strategies. A new study by a team of scientists - Prof. D. Nagesh Kumar from the Indian Institute of Science, Bangalore and Prof. K. Srinivasa Raju from BITS-Pilani, Hyderabad campus, has analyzed numerous available GCMs to choose the best that would be applicable in the Indian context. Such analysis helps in developing the best resource planning strategies and the best climate models that can be used for localized needs.
The world is definitely getting hotter, thanks to climate change – the topic that is hottest at the moment! What responsibilities do scientific institutes and businesses have, to make this world a cooler place, quite literally? Who can explain this better than Ms. Gilbert, Head of Policy at the Grantham Institute - Climate Change and Environment at Imperial College London! Ms. Gilbert is engaged in connecting relevant research across universities with policy-makers and businesses. In a candid interview during her visit to the Divecha Centre for Climate Change at the Indian Institute of Science, she opens up on her role and its challenges, the opportunities this situation presents, and her opinions on actions that need to be taken in tackling climate change.
In 2013, melting of the Chorabari glacier led to heavy floods in Uttarakhand and Himachal Pradesh, causing massive loss of life and property. Glacier lake outburst floods (GLOF) like this, have become a major safety concern in the Himalayas and other mountainous regions across the world. A group of researchers from the Indian Institute of Science, Bengaluru has now developed a unique model that can help prevent massive damages. Led by Prof. Anil Kulkarni at the Divecha Centre for Climate Change, the model serves as a tool for safe planning and timely monitoring of glaciers.
To most of us, the Himalayas is a snow clad, dry and cold mountain range. But trained eyes see through this apparent homogeneity and interpret the observed variations to understand the local climate and its implications. As a testimony to this, scientists from the Snow & Avalanche Study Establishment (SASE), Him Parisar, Chandigarh and the Divecha Center for Climate Change, Indian Institute of Science, Bangalore, have recently published a study on the variations in the 'whiteness of snow' across the Himalayas and its relationship with the mean winter air temperature and glacial stability.
Hydrologists and water resource managers have long depended on historical data for predicting droughts. However, according to a new study, this route may not give reliable predictions due to climate change caused by human activities. The study was carried out by researchers from the Indian Institute of Science, Bangalore.

Aerosols are extremely small solid or liquid particles that remain suspended in air. Examples of such aerosols include dust, smoke and deodorant sprays. Apart from causing local air pollution, these particles reflect and absorb radiation from the sun and hence affect both local and global climate. A recent study published in the International Journal of Climatology has investigated how soot aerosols accumulating in other parts of Asia influence the Indian summer monsoon.
