22nd APRIL: EARTH DAY

Earth Day is a day that is intended to inspire awareness and appreciation for the Earth's natural environment. Earth Day was founded by United States Senator Gaylord Nelson as an environmental teach-in first held on April 22, 1970. While this first Earth Day was focused on the United States, an organization launched by Denis Hayes, who was the original national coordinator in 1970, took it international in 1990 and organized events in 141 nations.Earth Day is now coordinated globally by the Earth Day Network, and is celebrated in more than 175 countries every year. Numerous communities celebrate Earth Week, an entire week of activities focused on environmental issues. In 2009, the United Nations designated April 22 International Mother Earth Day.

DAYLIGHT SAVINGS TIME

This Sunday morning, we'll be changing the time one hour ahead. Daylight saving time (DST)—also summer time in British English and European official terminology —is the practice of temporarily advancing clocks during the summertime so that afternoons have more daylight and mornings have less. Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn. Modern DST was first proposed in 1895 by George Vernon Hudson. Many countries have used it since then.
The practice has been both praised and criticized. Adding daylight to afternoons benefits retailing, sports, and other activities that exploit sunlight after working hours, but causes problems for farming, evening entertainment and other occupations tied to the sun. Its effect on health and crime is less clear. Although an early goal of DST was to reduce evening usage of incandescent lighting, formerly a primary use of electricity, modern heating and cooling usage patterns differ greatly, and research about how DST currently affects energy use is limited or contradictory.
DST clock shifts present other challenges. They complicate timekeeping, and can disrupt meetings, travel, billing, recordkeeping, medical devices, heavy equipment, and sleep patterns. Software can often adjust computer clocks automatically, but this can be limited and error-prone, particularly when DST protocols are changed.

2011, INTERNATIONAL YEAR OF FORESTS

The year 2011 was declared the International Year of Forests by the United Nations to raise awareness and strengthen the sustainable forest management, conservation and sustainable development of all types of forests for the benefit of current and future generations.
Forests are an integral part of global sustainable development. According to World Bank estimates, more than 1.6 billion people depend on forests for their livelihoods. The forest product industry is a source of economic growth and employment, with global forest products traded internationally in the order of $270 billion.
The UN’s Food and Agriculture Organization (FAO) estimates that every year 130,000 km² of the world's forests are lost due to deforestation. Conversion to agricultural land, unsustainable harvesting of timber, unsound land management practices, and creation of human settlements are the most common reasons for this loss of forested areas.
According to the World Bank, deforestation accounts for up to 20 percent of the global greenhouse gas emissions that contribute to global warming. FAO data estimates that the world's forests and forest soil store more than one trillion tons of carbon – twice the amount found in the atmosphere.
The World Bank estimates that forests provide habitats to about two-thirds of all species on earth, and that deforestation of closed tropical rainforests could account for biodiversity loss of as many as 100 species a day.
Governments, regional and international organizations and civil society organizations are expected to create national committees and designate focal points in their respective countries to facilitate organization of activities in support of the International Year of Forests.

THE ULTIMATE GLOBAL ISSUE: CLIMATE CHANGE

Climate change is a change in the statistical distribution of weather over periods of time that range from decades to millions of years. It can be a change in the average weather or a change in the distribution of weather events around an average (for example, greater or fewer extreme weather events). Climate change may be limited to a specific region, or may occur across the whole Earth.
In recent usage, especially in the context of environmental policy, climate change usually refers to changes in modern climate. It may be qualified as anthropogenic climate change, more generally known as global warming.

Factors that can shape climate are climate forcings. These include such processes as variations in solar radiation, deviations in the Earth's orbit, mountain-building and continental drift, and changes in greenhouse gas concentrations. There are a variety of climate change feedbacks that can either amplify or diminish the initial forcing. Some parts of the climate system, such as the oceans and ice caps, respond slowly in reaction to climate forcing because of their large mass. Therefore, the climate system can take centuries or longer to fully respond to new external forcings

Meanwhile the United Nations Climate Change Conference is being held at Copenhagen with little success in taking decisions as talks are at a deadlock. Below enclosed are diagrams, pictures and even jokes on the issue:
