| Summary/Abstract |
Each year, the effects of climate change are coming into sharper focus. Barely a month goes by without some fresh bad news: ice sheets and glaciers are melting faster than expected, sea levels are rising more rapidly than ever in recorded history, plants are blooming earlier in the spring, water supplies and habitats are in danger, birds are being forced to find new migratory patterns.The odds that the global climate will reach a dangerous tipping point are increasing. Over the course of the twenty-first century, key ocean currents, such as the Gulf Stream, could shift radically, and thawing permafrost could release huge amounts of additional greenhouse gases into the atmosphere. Such scenarios, although still remote, would dramatically accelerate and compound the consequences of global warming. Scientists are taking these doomsday scenarios seriously because the steady accumulation of warming gases in the atmosphere is forcing change in the climate system at rates so rapid that the outcomes are extremely difficult to predict.Eliminating all the risks of climate change is impossible because carbon dioxide emissions, the chief human contribution to global warming, are unlike conventional air pollutants, which stay in the atmosphere for only hours or days. Once carbon dioxide enters the atmosphere, much of it remains for over a hundred years. Emissions from anywhere on the planet contribute to the global problem, and once headed in the wrong direction, the climate system is slow to respond to attempts at reversal. As with a bathtub that has a large faucet and a small drain, the only practical way to lower the level is by dramatically cutting the inflow. Holding global warming steady at its current rate would require a worldwide 60-80 percent cut in emissions, and it would still take decades for the atmospheric concentration of carbon dioxide to stabilize.

| Summary/Abstract |
Illegal immigration has become a global problem these days. There are so many countries all over the world facing challenges of demographic disturbances because of illegal immigration. Immigration is generally defined as the movement of person or group of persons from one geographical unit to another country across an administrative or political border, wishing to settle permanently or temporarily in a place other than the place of origin.

| Summary/Abstract |
9/11 and the demolition of the World Trade Centre — the icon and emblem of
the liberal world — by Al Qaeda terrorists has been etched in the memories
of the world. Until then, the West did not think of terrorism as a significant
threat as they were barely dealing with it on their home turf. Countries like
India had suffered from cross border terrorism, extremism, and insurgency
from Pakistan based terrorists, engineered and nurtured by the Pakistani deep
state, for over two decades already. Geo politics was a convenient tool to
overlook the nexus of state and non-state actors, and they were selectively
used by big powers. This is well documented in the growth of the Mujahideen
and the Taliban. This nonchalance proved to be a disaster and demonic in
times to come. Only proforma concerns were expressed before 9/11, with
occasional intelligence exchanges with friendly countries. Terrorism, or the
fight against it, was a fashionable choice and not an existential problem. In
fact, many a time it was even justified on certain grounds, and implied goals
or a sympathetic view was taken. Zero tolerance of terrorism was an alien
concept — at least in practice.
