On a planetary precipice

Every part of the planet and every person is affected by pollution which is the world’s largest killer.

everyone is affected by pollution, some are directly exposed by handling chemicals at work or by living in the 80% of cities whose air doesn’t meet UN health standards. Others are among the 3.5 billion people who rely on our polluted seas for food, or make up the 2 billion who still do not have access to clean toilets.

Nearly a quarter of all deaths worldwide – or 12.6 million people a year – are due to environmental causes. “The health effects are stark, with air pollution alone killing some 6.5 million annually, affecting mostly poor and vulnerable people.”

Ecosystems are also “greatly damaged” by coastal, wastewater and soil pollution, it warns, adding that the vast majority of the world’s wastewater is released “untreated”, affecting drinking water to 300 million people.

“The only answer to the question of how we can all survive on this one planet with our health and dignity intact is to radically change the way we produce, consume and live our lives,” said on this Ligia Noronha, one of the report’s coordinators.


 UN Environment Programme warned that pledges made under the Paris Climate Change Agreement are only “a third of what is required by 2030 to avoid the worst impacts of climate change.”
“One year after the Paris Agreement entered into force, we still find ourselves in a situation where we are not doing nearly enough to save hundreds of millions of people from a miserable future,” said the UNEP chief . 
As things stand, “even full implementation of current national pledges makes a temperature rise of at least 3 degrees Celsius by 2100 very likely.”
The UN weather agency on the same day, 30 October 2017, warned that the levels of carbon dioxide (C02) surged at “record-breaking speed” to new highs in 2016. Petteri Taalas, Secretary-General of the World Meteorological Organization (WMO), issued this alert in Geneva at the launch of the organisation’s Greenhouse Gas Bulletin, indicating that carbon dioxide concentrations reached 403.3 parts per million in 2016, up from 400 parts per million in 2015.
“We have never seen such big growth in one year as we have been seeing last year in carbon dioxide concentration,” said Taalas. The new figures reveal “we are not moving in the right direction at all,” he added that “in fact we are actually moving in the wrong direction when we think about the implementation of the Paris Agreement and this all demonstrates that there is some urgent need to raise the ambition level of climate mitigation, if we are serious with this 1.5 to 2C target of Paris Agreement.”
To put that into perspective, WMO says that before the industrial era, a CO2 change of 10 parts per million took between 100 and 200 years to happen.
“What we are doing now with the atmosphere is 10 to 20 times faster than ever been observed in the history of the planet,” Tarasova said. In fact, according to the WMO’s report, which covers all atmospheric emissions, CO2 concentrations are now 145 percent of pre-industrial levels.
After carbon dioxide, the second most important greenhouse gas is methane; its levels rose last year but slightly less than in 2014. Nitrous oxide is the third most warming gas; it increased slightly less last year than over the last decade.
How many summits, reports, warnings, alerts, and scientific evidence are still needed for humans to halt this process of self-destruction? How long will it take to understand that there is an alternative economic system which can mitigate and reverse climate change?
