Simpler route to global warming management being missed

A scientific report has stated that while the world is looking at carbon dioxide as the major concern with respect to climate change, other possibly easier ways of bringing down global warming are being missed out on.

The Arctic Monitoring and Assessment Programme (AMAP) set up by the Arctic Council produced the said report, which claimed that the temperature on earth could be brought down by earth by approximately 0.2 degrees Celsius between now and 2050 by putting down a heavier hand on the other pollutants except carbon dioxide, such as methane, black carbon and atmospheric ozone.

Methane is a greenhouse gas like carbon dioxide, but is 20 times more dangerous in its potential for global warming. However, it is much easier to deal with, as it is a short-lived pollutant. An even shorter life-span is carried by black carbon, which is produced from incomplete burning of fossil fuels.

The accumulation of greenhouse gases, which might even remain hanging in the atmosphere for over a century, is the main cause behind global warming.

“Actions to reduce methane emissions could slow the global warming expected by 2050 by approximately 0.2 degree Celsius. A reduction of about 0.25 degree Celsius in the Arctic could be achieved through global actions to reduce emissions of black carbon and co-emitted air pollutants,” the report, released during the Paris conference, says, according to a statement by the AMAP.

“Unlike carbon dioxide, short-lived climate pollutants (SLCPs) have a relatively short residence time in the atmosphere (of a few days to about a decade). The shorter the lifetime, the more quickly atmospheric concentrations can be reduced by lowering emissions. This means that action on SLCPs has the potential to slow the rate of climate warming on a comparatively shorter time scale,” said the statement.

The statement additionally said that this step should not be seen as a replacement to the actions being taken on carbon dioxide and harsher greenhouse gases.

“Action on black carbon and ozone has added benefits since these pollutants are also harmful to human health,” it said.

The research also showed that if black carbon and methane were aggressively curbed, the temperature rise since the industrial age could easily be stalled at the 2 degrees Celsius mark.

Climate Change Would Affect Health Of Indian Children: Lancet

Climate change would hit health of Indian children hard, says study by Lancet

Children in India will be particularly vulnerable to the ill effects of climate change such as worsening air quality, higher food prices and rise in infectious diseases, warns a new study published in the journal The Lancet.

Climatic suitability for the Vibrio bacteria that cause cholera is rising three per cent a year in India since the early 1980s, said the report.

“With its huge population and high rates of healthcare inequality, poverty, and malnutrition, few countries are likely to suffer from the health effects of climate change as much as India,” said study co-author Poornima Prabhakaran from the Public Health Foundation of India.

“Diarrhoeal infections, a major cause of child mortality, will spread into new areas, whilst deadly heatwaves, similar to the one in 2015 that killed thousands of people in India, could soon become the norm,” Prabhakaran said.

Through adolescence and into adulthood, a child born today will be breathing more toxic air, driven by the fossil fuels and made worse by rising temperatures.

This is especially damaging to young people as their lungs are still developing, so polluted air takes a great toll, contributing to reduced lung function, worsening asthma, and increasing the risk of heart attacks and stroke.

Later in life, a child born today will face increased risk from severe floods, prolonged droughts, and wildfires.

Most countries have experienced an increase in people exposed to wildfires since 2001-2004 with a financial toll per person 48 times larger than flooding.

India alone saw an increase of more than 21 million exposures, and China around 17 million, resulting in direct deaths and respiratory illness as well as loss of homes, said the report.

“Over the past two decades, the Government of India has launched many initiatives and programmes to address a variety of diseases and risk factors. But this report shows that the public health gains achieved over the past 50 years could soon be reversed by the changing climate,” Prabhakaran said.

The “Lancet Countdown on Health and Climate Change” is a yearly analysis tracking progress across 41 key indicators, demonstrating what action to meet Paris Agreement targets — or business as usual — means for human health.

The project is a collaboration between 120 experts from 35 institutions including the World Health Organisation (WHO), World Bank, University College London, and Tsinghua University.

For the world to meet its UN climate goals and protect the health of the next generation, the energy landscape will have to change drastically, the report warns.

Nothing short of a 7.4 per cent year-on-year cut in fossil CO2 emissions from 2019 to 2050 will limit global warming to the more ambitious goal of 1.5 degree Celsius, said the report. If the world follows a business-as-usual pathway, with high carbon emissions and climate change continuing at the current rate, a child born today will face a world on average over 4 degree Celsius warmer by their 71st birthday, threatening their health at every stage of their lives.
