The recent earthquake in Japan illustrates the dangers of even safe, government-monitored nuclear energy. When disaster occurs, how can we safely evacuate the large numbers of affected people? Indeed, how can we even be sure how far the evacuation radius should extend? Radiation can also enter the food chain, causing damage from the bottom (phytoplankton and microscopic soil organisms) all the way to the top. Once again, the price paid for cheap power is much greater than what is seen on the electric bill.

The enormous oil disaster that hit the Louisiana Gulf Coast is just one of a frighteningly high number of environmental crises that have led to toxic residue. From the Love Canal neighborhood of the 1970s to the Exxon Valdez oil tanker crash of 1989, from the Chernobyl disaster of 1986 to Japan’s Fukushima nuclear plant incident in 2011—the list goes on. Often, the stories are not newsmakers, but simply an unpleasant part of life for the people who live near toxic sites such as in the stories of Centralia, Pennsylvania and Hinkley, California. In many cases, people in these neighborhoods can be part of a cancer cluster without realizing the cause.

Climate change

World systems analysis suggests that core nations (like the U.S. and Western Europe) were historically the greatest source of greenhouse gases, but have now evolved into postindustrial societies. Now that semi-peripheral and peripheral nations are industrializing, the core nations wish to enact strict protocols regarding the causes of global warming (since their economies are no longer so dependent on greenhouse-gas-causing industries). However, the semi-peripheral and peripheral nations rightly point out that they only want the same economic chance to evolve their economies, and since they were unduly affected by the progress of core nations, if the core nations now insist on “green” policies, they should pay offsets or subsidies of some kind. There are no easy answers to this conflict. It may well not be “fair” that the core nations benefited from ignorance during their industrial boom. But with China leading the way as a top greenhouse gas emitter, it matters less to the planet whether they get their fair shake at polluting. The international community continues to work toward a way to manage climate change. The Durban Talks that concluded in December 2011 point to a willingness by both core countries and peripheral nations to move toward a legally binding instrument for all countries (World Resource Institute 2011).

Climate change, which used to be called global warming, is a deeply controversial subject, despite decades of scientific research that demonstrates its existence. Climate change refers to long-term shifts in temperatures due to human activity and, in particular, the release of greenhouse gases into the environment. While the planet as a whole is warming––hence the term global warming––the term climate change is now used because the short-term variations can include higher or lower temperatures, despite the overarching trend toward warmth. Another effect is more extreme weather. There are increasingly more record-breaking weather phenomena, from the number of Category 4 hurricanes to the amount of snowfall in a given winter. These extremes, while they make for dramatic television coverage, can cause immeasurable damage to crops, property, and even lives.

why surface tension is zero at critical temperature
Shanjida
I think if critical temperature denote high temperature then a liquid stats boils that time the water stats to evaporate so some moles of h2o to up and due to high temp the bonding break they have low density so it can be a reason
