100 mln to die by 2030 if world fails to act on climate

               LONDON (Reuters) – More than 100 million people will die and global economic growth will be cut by 3.2 percent of gross domestic product (GDP) by 2030 if the world fails to tackle climate change, a report commissioned by 20 governments said on Wednesday.

As global average temperatures rise due to greenhouse gas emissions, the effects on the planet, such as melting ice caps, extreme weather, drought and rising sea levels, will threaten populations and livelihoods, said the report conducted by humanitarian organisation DARA.

It calculated that five million deaths occur each year from air pollution, hunger and disease as a result of climate change and carbon-intensive economies, and that toll would likely rise to six million a year by 2030 if current patterns of fossil fuel use continue.

More than 90 percent of those deaths will occur in developing countries, said the report that calculated the human and economic impact of climate change on 184 countries in 2010 and 2030. It was commissioned by the Climate Vulnerable Forum, a partnership of 20 developing countries threatened by climate change.

“A combined climate-carbon crisis is estimated to claim 100 million lives between now and the end of the next decade,” the report said.

It said the effects of climate change had lowered global output by 1.6 percent of world GDP, or by about $1.2 trillion a year, and losses could double to 3.2 percent of global GDP by 2030 if global temperatures are allowed to rise, surpassing 10 percent before 2100.

It estimated the cost of moving the world to a low-carbon economy at about 0.5 percent of GDP this decade.

COUNTING THE COST

Responding to the report, Oxfam International said the costs of political inaction on climate were “staggering”.

“The losses to agriculture and fisheries alone could amount to more than $500 billion per year by 2030, heavily focussed in the poorest countries where millions depend on these sectors to make a living,” said executive director Jeremy Hobbs.

British economist Nicholas Stern told Reuters earlier this year investment equivalent to 2 percent of global GDP was needed to limit, prevent and adapt to climate change.

His report on the economics of climate change in 2006 said that without any action to tackle climate change, the overall costs and risks of climate change would be equivalent to a cut in per-capita consumption of perhaps up to 20 percent.

Temperatures have already risen by about 0.8 degrees Celsius above pre-industrial times. Almost 200 nations agreed in 2010 to limit the global average temperature rise to below 2C (3.6 Fahrenheit) to avoid dangerous impacts from climate change.

But climate scientists have warned that the chance of limiting the rise to below 2C is getting smaller as global greenhouse gas emissions rise due to burning fossil fuels.

The world’s poorest nations are the most vulnerable as they face increased risk of drought, water shortages, crop failure, poverty and disease. On average, they could see an 11 percent loss in GDP by 2030 due to climate change, DARA said.

“One degree Celsius rise in temperature is associated with 10 percent productivity loss in farming. For us, it means losing about 4 million metric tonnes of food grain, amounting to about $2.5 billion. That is about 2 percent of our GDP,” Bangladesh’s Prime Minister Sheikh Hasina said in response to the report.

“Adding up the damages to property and other losses, we are faced with a total loss of about 3-4 percent of GDP.”

Even the biggest and most rapidly developing economies will not escape unscathed. The United States and China could see a 2.1 percent reduction in their respective GDPs by 2030, while India could experience a more than 5 percent loss.

Global Warming IPCC 2007 World Temperature Report-Darker the lines-Hotter the region

Washington: The Earth will be 2.4 degree Celsius warmer by 2020 if the world continues with the business-as-usual approach to climate change and India would be one of the hardest hit countries witnessing upto 30 percent reduction in crop yields, a new study has claimed.
The rising temperatures will adversely affect the world”sfood production and India would be the hardest hit, accordingto the analysis by the Universal Ecological Fund (FEU-US), theUS subsidiary of FEU founded in Argentina in 1990.
The report titled ”The Food Gap — The Impacts of ClimateChange on Food Production: A 2020 Perspective” predicted thatcrop yield in India, the second largest world producer of riceand wheat, would fall up to 30 per cent by the end of thisdecade.

The report, however, noted that the impacts of climatechange would vary from region to region. While central andsouthern region would witness adverse impacts, the impactscould be beneficial for East and South-East Asia, the reportpredicted.

The two most populated countries in the world, India andChina, would experience different impacts. While India couldsee a fall in its crop yield, China — the largest producer ofrice and wheat in the world — is expected to increase itscrop yields up to 20 per cent, said the report.

However, the overall impact of a warmer planet on globalfood production would be massive, said the report, adding thatthe most significant impacts would be on the top 20 producersof each of the four crops: wheat, rice, maize and soybean,respectively.

It has predicted that global wheat production during thattime would experience a 14 per cent deficit between productionand demand; while there will be an 11 per cent deficit in riceproduction and 9 per cent in maize (corn) production. Soybeanis the only crop showing an increase in global production,with an estimated 5 per cent surplus, the report said.

“The evidence that man-made greenhouse gases would causethe temperature of the planet to rise has been available foralmost two decades. The IPCC (Intergovernmental Panel onClimate Change) Fourth Assessment Report (2007) has concludedthat, unequivocally, the Earth”s warming is anthropogenic(man-made),” said FEU scientific adviser Dr Osvaldo Canziani,the former Co-Chair of Working Group II of the IPCC.

The analysis and data utilised to produce the report isbased on key documents already published by the IPCC and otherUN agencies.

“The key to our report was to analyse, synthesise andupdate published documents and data from disparate sources andpresent it in an accessible way,” Liliana Hisas, ExecutiveDirector of FEU-US and author of the report, said.
