Paris Climate Change Conference: Countries Pledge To Ward Off Severe Warming

More than 190 countries are expected to meet in Paris for the climate change conference to implement a process to reduce emission of greenhouse gases over time.

Pledges made in the lead-up to next week's major Paris climate change conference can avert severe climate change, but only if the words are turned into long-term action, says a new study.

More than 190 countries are meeting in Paris next week to create a durable framework for addressing climate change and to implement a process to reduce greenhouse gases over time. A key part of this agreement would be the pledges made by individual countries to reduce their emissions.

Health Effects of Global Warming/What is Global Warming?
Greenhouse effect causes excessive heat to build up in the earth’s atmosphere causing global warming and affects the environment and health.

‘Many countries have submitted pledges to combat climate change, known as Intended Nationally Determined Contributions (INDCs), based on their own national circumstances.’

The study shows that if implemented and followed by measures of equal or greater ambition, the Paris pledges have the potential to reduce the probability of the highest levels of warming, and increase the probability of limiting global warming to 2 degrees Celsius.

In the lead up to the Paris meetings, countries have announced the contributions that they are willing to make to combat global climate change, based on their own national circumstances.

These Intended Nationally Determined Contributions, or INDCs, take many different forms and extend through 2025 or 2030. Examples of these commitments include the United States' vow to reduce emissions in 2025 by 26-28 percent of 2005 levels and China's pledge to peak emissions by 2030 and increase its share of non-fossil fuels in primary energy consumption to around 20 percent.

Climate Change Turns Foliage Less Nutritious in Rainforest
Nutritional quality of foliage in Kibale National Park in Uganda, an evergreen rainforest, has substantially declined over the last 15-30 years.

In the study, the scientists tallied up these INDCs and simulated the range of temperature outcomes the resulting emissions would bring in 2100 under different assumptions about possible emissions reductions beyond 2030.

Lead author Allen Fawcett of the U.S. Environmental Protection Agency said that they analyzed not only what the commitments would achieve over the next ten to fifteen years, but also how they might lay a foundation for the future.

The World Is Set to Go Dark for Earth Hour to Raise Awareness on Climate Change
‘Earth Hour 2015’ will be observed by switching off lights from 8.30pm to 9.30pm local time on March 28 in 172 countries across the world.

The study is published in Science.
