storage is also dependant on the integrity of the seal in the cap rock or the impermeable
rock layer that overlies a reservoir. The strength and composition of the seal rock under
different injection pressures determine if the CO 2 will be contained or ultimately leak
out of the reservoir. The CCS as a bridge to renewable energy and sustainability, is a
‘bridging’ technology that will ensure that emission targets are achieved. However,
Carbon Capturing and Storage is not a 'silver bullet' (straightforward solution perceived
to have extreme effectiveness) to combat global warming.
The global recovery of hydrocarbons from the subsurface using integrated
geoscience and engineering technology, termed as 'petroleum geoengineering' is an
activity with global impact.
The modern concept of geoengineering is usually taken to mean proposals to
deliberately manipulate the Earth's climate to counteract the effects of global warming
from greenhouse gas emissions. Some geoengineering techniques are based on carbon
sequestration. These seek to reduce greenhouse gases in the atmosphere directly. These
include direct methods (e.g. carbon dioxide air capture) and indirect methods (e.g.
ocean iron fertilization). These techniques can be regarded as mitigation of global
warming. However, there is need of further researches and development efforts for
adapting currently proven and emerging geophysical tools applied for other applications
for CO 2 and also in developing new innovative tools for CO 2 sequestration application.

Surface energy balance is influenced by changing land surface characteristics
which is expressed in the form of Land Surface Temperature (LST) and its spatiotemporal
variations. LST is regarded as a function of four surface and sub surface
properties: albedo, emissivity, the thermal properties of urban construction materials
(including moisture), and the composition and structure of urban canopy (Goward,
1981). LST, which is heavily influenced by urban surface structures, is a significant
parameter in urban environmental analysis. This study attempts to examine the effect of
impervious surfaces (IS) spatial patterns on LST over Pune, India. An NDVI and TC
band II approach was adopted to estimate the IS by employing Landsat TM and ETM+
data of 1990 and 2009. One of the indicators of increasing IS is the built-up area, and
therefore, IS is represented by built-up area in this study. LST was retrieved for both the
