Changing Pattern of World Climate

Changing Pattern of World Climate

Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions or the distribution of events around that average. Climate change may be limited to a specific region or may occur across the whole Earth.

Curated Facts

The current warming trend is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years

The U.N. climate panel said all nations will be vulnerable to the expected increase in heat waves, more intense rains and floods and a probable rise in the intensity of droughts.

Aimed largely at policymakers, the report by the Intergovernmental Panel on Climate Change makes clear nations need to act now, because increasingly extreme weather is already a trend.

February 2012 was the coolest February on record since 2008. However, February 2012 also marks the 324th consecutive month with a global temperature above the 20th century average. The last month with below average temperatures was February 1985.

Global warming has become perhaps the most complicated issue facing world leaders. Warnings from the scientific community are becoming louder, as an increasing body of science points to rising dangers from the ongoing buildup of human-related greenhouse gases — produced mainly by the burning of fossil fuels and forests.

A comprehensive new review of research on episodes of carbon-driven disruption of ocean and climate conditions over the last 300 million years shows the power of a big pulse of carbon dioxide to profoundly affect the environment.

The review, which is being published in the journal Science on Friday, concludes that the human-driven buildup of carbon dioxide under way now appears to be far outpacing past natural events, meaning that, for ocean chemistry particularly, the biological implications are potentially enormous — and laden with the kind of uncertainty that is hard to see as a source of comfort.

The fact that there has been little to no net warming of the Earth over the past dozen or so years, in almost all of the global temperature databases that are maintained by the various research groups that study this important subject, has led many people to suggest that anthropogenic CO2 emissions are not having the large global warming effect the world's climate alarmists assign to it. And this fact has led many climate alarmists to devise complex explanations for this dilemma.

Climate change will alter natural systems in the United States and will affect many parts of the U.S. economy. The climate is changing and will continue to change as a result of increased greenhouse gas concentrations in the atmosphere. Although there are many uncertainties about how regional climate will change, the effects of climate change are likely profound.

The way Henry Waxman sees it, Congress faces two huge challenges: cutting the deficit and protecting the country from the worst consequences of climate change. Why not act on both together?

Yet despite all the complexities, a firm and ever-growing body of evidence points to a clear picture: the world is warming, this warming is due to human activity increasing levels of greenhouse gases in the atmosphere, and if emissions continue unabated the warming will too, with increasingly serious consequences.

Since March 12, more than 7,000 warm temperature records (warm daily highs and warm overnight lows) have been set or tied, including numerous all-time monthly high temperature records.

Although studies have not yet been conducted on the main factors that triggered this heat wave and whether global warming may have tilted the odds in favor of the event, scientific studies of previous heat events clearly show that global warming increases the odds of heat extremes, in much the same way as using steroids boosts the chances that a baseball player will hit more home runs in a given year.
