See comment on PNAS paper by Tata Institute of Social Sciences
Spurious linkages between extreme temperatures and farmer suicides

A recent paper, published by the PNAS (Proceedings of the National Academy of
Sciences of the United States) and authored by Tamma A. Carleton, titled “Climate
Change and Agricultural Suicides in India” claims that “temperature during India’s
main agricultural growing season has a strong positive effect on annual suicide rates.”

Dear All,

Please find attached the agenda for the workshop on "Performance and
Potential of Wind Energy Systems in India", to be held in Divecha Centre for
Climate Change, IISc, Bangalore, on 22 and 23 August, 2017. The workshop
will be held in the seminar hall of Divecha Centre for Climate Change.

As you are aware, the Indian government has set a target of having 60 GW of
wind capacity by 2022. While installing further wind mills, it would be very
useful to investigate the performance of the existing wind farms. A workshop
discussing performance of existing wind plants, wind potential and off-shore
wind would be very relevant at this point of time.

All are welcome.

It would be great if you could please confirm your participation by sending
an email to so that we can make the necessary
arrangements accordingly.

Warm Regards,

Article: Unravelling Diurnal Asymmetry of Surface Temperature in Different Climate Zones


Understanding the evolution of Diurnal Temperature Range (DTR), which has contradicting global and regional trends, is crucial because it influences environmental and human health. Here, we analyse the regional evolution of DTR trend over different climatic zones in India using a non-stationary approach known as the Multidimensional Ensemble Empirical Mode Decomposition (MEEMD) method, to explore the generalized influence of regional climate on DTR, if any. We report a 0.36 °C increase in overall mean of DTR till 1980, however, the rate has declined since then. Further, arid deserts and warm-temperate grasslands exhibit negative DTR trends, while the west coast and sub-tropical forest in the north-east show positive trends. This transition predominantly begins with a 0.5 °C increase from the west coast and spreads with an increase of 0.25 °C per decade. These changes are more pronounced during winter and post-monsoon, especially in the arid desert and warm-temperate grasslands, the DTR decreased up to 2 °C, where the rate of increase in minimum temperature is higher than the maximum temperature. We conclude that both maximum and minimum temperature increase in response to the global climate change, however, their rates of increase are highly local and depend on the underlying climatic zone.

Announcements / CliMT: A climate modelling framework
« on: July 25, 2017, 08:04:04 AM »

Hello All,

as some of you may be aware, we have been involved in
building a climate modelling framework that can be used
entirely from Python.

I'm happy to inform you all about the first release of CliMT.
This version of CliMT is capable of running as a simplified
GCM, with a spectral dynamical core. The components
currently available in CliMT are suitable for research use.

Please do play around, and I am happy to receive any

Documentation, including installation instructions, are
available at:

The code is available at:

which contains many examples that you can adapt for
your own needs.

Kavitha Kuruganti
Alliance for Sustainable & Holistic Agriculture (ASHA)

25 July, 5pm, Chokshi Hall IISc

Seven years after India witnessed a big debate about Bt brinjal, a GM
food crop that was cleared by regulators for commercial cultivation in
the country, which was subsequently placed on an indefinite moratorium,
the controversy is back to the fore again. This time, it is about a
herbicide tolerant GM mustard, which if approved by the Ministry of
Environment and Forests, would be the first GM food crop to be allowed
in farmers' fields for commercial cultivation. This GM mustard had
received regulatory clearance in May 2017. While the proponents of GM
mustard claim that GM technology deployed in mustard will allow for
hybridisation in the crop, which then has the potential to increase
yields and bring down edible oil imports into India, the opponents of
this GM food crop are arguing that the benefit claims as well as safety
claims are unfounded and that GM mustard is not needed in the first

Kavitha Kuruganti is a leading sustainable agriculture activist, known
for her views against GM mustard. She is in the forefront of a campaign
that is seeking to ensure that this HT GM food crop is not approved in
India. In this talk, she explains the resistance against GM mustard from
all over the country and reasons for the same.


Interesting. Thanks for sharing. :)



TITLE: "An Extreme Event Attribution Study of the Heat Wave of Summer 2015 and Chennai Rain Event of December 2015"





Dear All:

We are organizing a two-day short course on "Advances in Data Assimilation Techniques" under Continuing Education Programme in Indian Institute of Technology (IIT) Delhi on 21-22 September 2017. 

This two-day course will provide a glimpse of the advancements in data assimilation techniques, focusing especially on the land surface models and assimilation techniques. The speakers will initiate an introduction to the basics of data assimilation, and introduction to land data assimilation in weather and climate models. The course will also focus on the sources of uncertainty, characterization of uncertainty of model predictions, how data assimilation is essential for characterizing and reducing uncertainty and the feasibility of these in large scale high resolution model predictions.

For more details about the course, speakers and registration, please download the brochure from:

Last date of registration is 20th July 2017.  Please note that registration is limited to only 30 participants, on a first come first serve basis.

Please write to me, if you have any queries.

Thanks & Regards,

Dear All,


Title: "Climate Warming of Black and Brown Carbon Aerosols in South Asia"

Speaker: Dr. Srinivas Bikkina, Stockholm University, Sweden

Venue: Seminar Hall, Centre for Atmospheric and Oceanic Sciences (CAOS)

Date & Time: Monday, 12 June 2017; 11:30 AM

Tea at 11:15 AM



Aerosols constitute one of the main uncertainties in our current understanding
of the climate system. Although aerosols cause net cooling, certain
carbonaceous aerosols, e.g., black carbon (BC), may contribute to a
significant, but highly uncertain warming, ranging 0.2 - 2.1 W/m2 (compared
with 1.6 – 2.0 W/m2 for CO2). Carbonaceous aerosols, emitted mostly from the
fossil-fuel combustion (FF-comb: vehicular emissions and coal) and biomass
burning emissions (BBEs), account for a major fraction of atmospheric fine
mode particulate matter (up to 70%), cause large uncertainty in assessing the
climate effects of aerosols (e.g., surface dimming, weakening of monsoon,
intensification of tropical cyclones, and melting of the Himalayan glaciers in
S. Asia). In addition, the health burden of the BC-containing air pollution on
individuals and society is large, including premature deaths of ~1-2 million
annually in South and East Asia alone (e.g., WMO/UNEP, 2011). However, these
effects are poorly constrained due to: 1. Uncertain emission estimates from
different sources; 2. Uncertain absorption due to mixing/coating with
non-absorbing aerosols; 3. Uncertain atmospheric lifetimes, and; 4. The
mixture of BC and other absorbing aerosol species, e.g., brown carbon (BrC).
For these multiple effects, the division between different sources is
important, particularly between biomass vs. fossil fuel combustion, as the
resulting BC/BrC properties interact differently with atmospheric radiation,
geochemical cycles, and human respiratory effects.  In this presentation, I
will present/show how the dual-carbon isotopic composition of carbonaceous
aerosols coupled with some organic/inorganic chemical markers (a new & cutting
edge tool) can be useful for better understanding/assessing the relative
significance of emission sources and their contributions, optical properties
of both BC/BrC aerosols as well as the significance of the primary versus
secondary organic aerosols over S. Asia through some preliminary results.
