Up till now, the Paris climate change summit has dominated the news stories in the month of December. All the hoopla surrounding the Paris climate change summit is completely justified considering the disastrous impact of climate change that awaits us in the future. If you are still doubtful about the gravity of the issue, the following images might help you in coming to terms with the reality.

polar bear

No image better exemplifies our gloomy future than this image of a polar bear trying to hold on to a fast melting glacier. Over the past 150 years, the average temperature of our planet has increased by 2.5 degrees, thus causing the Antarctica, Greenland and Arctic ice to melt faster than ever, which in turn raises the water levels across the world. This is specially dangerous for low-lying coastal nations which would submerge in the ocean if this trend continues.

drought

According to the scientists, floods and droughts are likely to increase with the increasing global temperatures. Changing patterns of rainfall, such as the one that wrecked havoc in Chennai are likely to become increasingly common.

water scarcity

The issue of fresh water scarcity is likely to assume much greater proportions in the coming years with increase in the melting rates of ice caps.

penguins

The population of polar animals such as penguins is on a constant decline. The population of Adélie penguins of Antarctica has declined to 1/3rd in the last 3 decades.

If these images aren’t enough to put across the challenge of climate change that we are up against, may be we don’t deserve the Earth after all.

World could see 140mn climate migrants by 2050: Report

  • Three regions can witness migration due to climate change
  • The regions also include South Asia
  • It is important to take measures to control climate change

Three densely populated regions of the world, including South Asia, could see internal climate migrants of over 140 million people in the next three decades if climate change impacts continue, a new World Bank Group report finds.

The report, “Groundswell — Preparing for Internal Climate Migration”, released on Monday, finds that unless urgent climate and development action is taken globally and nationally, the three regions — Sub-Saharan Africa, South Asia and Latin America — together could be dealing with tens of millions of internal climate migrants by 2050.

These people will be forced to move from increasingly non-viable areas of their countries due to growing problems like water scarcity, crop failure, sea-level rise and storm surges.

The “climate migrants” would be an addition to the millions of people already moving within their countries for economic, social, political or other reasons, the report warns. The exodus could create a looming humanitarian crisis and will threaten the development process.

However, with concerted actions — including global efforts to cut greenhouse gas emissions and robust development planning at the country level — this scenario could be dramatically reduced by up to 80 per cent or more than 100 million people.

The report is the first and most comprehensive study of its kind to focus on the nexus between slow-onset climate change impacts, internal migration patterns and, development in these three developing regions of the world.

World Bank Chief Executive Officer Kristalina Georgieva said the new research provides a wake-up call to countries and development institutions. “We have a small window now, before the effects of climate change deepen, to prepare the ground for this new reality,” Georgieva said.

It is important to control climate change now.

“Steps cities take to cope with the upward trend of arrivals from rural areas and to improve opportunities for education, training and jobs will pay long-term dividends. It’s also important to help people make good decisions about whether to stay where they are or move to new locations where they are less vulnerable.”

The research team, led by World Bank Lead Environmental Specialist Kanta Kumari Rigaud, include researchers and modellers from CIESIN Columbia University, CUNY Institute of Demographic Research, and the Potsdam Institute for Climate Impact Research.

They applied a multi-dimensional modelling approach to estimate the potential scale of internal climate migration across the three regions. They looked at three potential climate change and development scenarios, comparing the most “pessimistic” (high greenhouse gas emissions and unequal development paths), to “climate-friendly” and “more inclusive development” scenarios in which climate and national development action increases in line with the challenge. Across each scenario, they applied demographic, socio-economic and climate impact data at a 14 sq.km grid-cell level to model likely shifts in population within countries.

This approach identified major “hotspots” of climate in- and out-migration – areas from which people are expected to move and urban, peri-urban and rural areas to which people will try to move to build new lives and livelihoods. “Without the right planning and support, people migrating from rural areas into cities could be facing new and even more dangerous risks,” the report added.
