Natural Heritage

Natural Heritage
Preserving the natural patrimony is the most inexpensive and efficient environmental economics. The term natural heritage derives from the French "patrimoine naturel", the totality of natural assets, including those of historical, cultural or scenic beauty. It give us understanding the importance of natural environment: where we came from, what we do and how we will be. Our lives are connected to the landscapes of our daily lives, as well as we keep the memories of places we went. The destruction of these landscapes cause irreversible environmental damage, and are an insult to our memory, causing loss of quality of life.

Global CO2 emissions at record high in 2012 (CNN Money)

The world is moving in the wrong direction to limit global warming, with CO2 emissions rising to a record high in 2012, and four steps must be taken in order to keep the earth's temperature down, the International Energy Agency (IEA) said.

Energy-related CO2 emissions increased 1.4% last year, reaching a record high level of 31.6 gigatonnes.

The Paris-based IEA this week called for nations to agree to four energy policies by 2015, aiming to keep global warming from rising above 2°C by 2020. Without an agreement, CO2 emissions are likely to result in a temperature increase of between 3.6°C to 5.3 °C by around 2050, the IEA said.

"Amid concerns over global economic pressures, climate change has quite frankly slipped to the back burner of policy priorities," IEA Executive Director Maria van der Hoeven said in London.

The four energy policies the IEA wants nations to implement are primarily focused on energy-saving measures in appliances, lighting systems and heating and air-conditioning in buildings.

Other policies include limiting the use of inefficient coal power plants, especially in China, halving the level of methane released from oil and gas facilities, as well as phasing out fossil-fuel subsidies that encourage further consumption, most significantly in the Middle East.

Carbon emissions have caused more droughts and heat waves across the continents, and changes in tropical cyclones and storm patterns, harming agriculture production, the IEA said. "Sea levels have risen by 15-20 centimeters, on average, over the last century and this increase has accelerated over the past ten years," according to the report. "Oceans are warming and becoming more acidic, and the rate of ice-sheet loss is increasing, with the area of ice covering the Arctic Ocean in the summer diminishing by half over the last 30 years to a record low level in 2012."

A part of the 2010 Cancun Agreements, 91 countries, representing nearly 80% of global greenhouse gas emissions, have pledged to act. These pledges, however, collectively fall well short of what is necessary to deliver the 2°C goal, according to the IEA report.
China, Japan, India and the Middle East all contributed to the growth in global CO2emissions. China was the largest polluter, but the pace of its increase was one of the lowest in the last decade. IEA attributed China's improvement to a wider use of alternative energy.
