Use Every Resources To Help in Climate Change: Scientists

Individuals and civic groups have a big role to play in pushing governments to tackle climate threats.

Last-ditch efforts to hold climate change to the most ambitious target set by governments will likely require using every available technique rather than picking and choosing the most attractive ones, climate scientists said on Monday.

Dramatically reducing the use of coal, planting huge swaths of land with carbon-absorbing forest or powering most transport with electricity are no longer sufficient to bring about the swift transition needed, they said, with warming expected to pass the 1.5 degree Celsius (2.7 degrees Fahrenheit) mark in as little as 12 years.

“We can make choices about how much of each option to choose, but the idea you can leave anything out is impossible,” said Jim Skea, who jointly led a major scientific report analyzing the feasibility of holding global average temperature rise to 1.5 degrees C above pre-industrial levels, the most ambitious goal of the 2015 Paris Agreement.

The Intergovernmental Panel on Climate Change (IPCC) report, requested by governments, was issued ahead of a U.N. conference in December in Poland that will consider how to increase country ambitions to cut emissions and manage climate risks better.

Current government commitments to curb climate change under the Paris pact, even if fully met, would still leave the world on track for about 3 degrees of warming, scientists said.

To have a chance of meeting the 1.5 degrees goal, climate-changing emissions would have to plunge 45 percent by 2030 compared to 2010 levels, the report said.

As that would be an “unprecedented” rate of decline, it is more likely the world will overshoot the target, then try to return to it by sucking carbon from the air, scientists said.

Such “carbon removal” might happen by developing better technology to take out carbon dioxide from the atmosphere – now an extremely expensive process – or by planting many more forests that could be harvested and burned for energy, with emissions pumped into underground storage.

“We have not identified any pathways that get to 1.5 degrees Celsius without some kind of carbon dioxide removal,” Skea said.

But turning over much more land for energy production “could have implications for food security, ecosystems and biodiversity,” the British scientist warned, as competition for land grows.

All on board

Swiftly reducing emissions – even with carbon removal – will also require unprecedented levels of international cooperation, a particular challenge as some national governments, like that in the United States, look increasingly inward.

Making the needed emissions changes “is within the scope of what humans can achieve”, said Hans-Otto Portner, a German climate scientist and IPCC report co-chair.

But success “depends on political leadership,” he added.

Henri Waisman, a senior researcher at Paris-based think tank IDDRI and one of 91 report authors, said the report’s aim was to set out the types of transformation required as clearly as possible to inform discussions at U.N. climate talks and beyond.

Delaying action on climate change “is something that is explicitly contradicted in the report,” he told the Thomson Reuters Foundation.

If governments fail to ramp up their ambition to reduce heat-trapping emissions over the next two years, they will have consciously abandoned the 1.5 degree goal, he added.

Action in cities – which consume more than two-thirds of energy globally and account for about three-quarters of carbon emissions – are pivotal to meeting the target, said report author William Solecki, a professor at Hunter College-City University of New York.

That’s particularly true because most population growth in coming years “is going to be in urban areas – a lot of it particularly in small and medium-sized cities … in the global south,” he said.

Those cities will need more support to develop cleanly, prevent disasters and adapt to climate shifts, he added.

The scientists said the report was intended to guide more than just governments, however, and that action by everyone – including individuals and businesses – would be required to hold the line on climate change.

“There’s a lot we can do individually or within our communities,” said Debora Ley, a report author who works on adaptation and renewable energy in Latin America.

Personal changes might include everything from eating less meat to using energy-efficient appliances and reducing air travel, said Patricia Pinho, a Brazilian climate scientist and report author.

Individuals and civic groups have a big role to play in pushing governments to tackle climate threats, and are stepping up pressure as recognition of the danger grows, she said.

“We have to live our lives in a way that makes a difference. “Our life on this planet, our kids are at risk,” she said. (VOA)

Growing Inequality and Climate Change to Threaten Human Existence

Member nations unanimously adopted 17 sustainable development goals known as SDGs in 2015, setting out a wide-ranging "to-do" list

Growing inequality and climate change will not only derail progress toward global sustainability goals but also will threaten human existence, leading scientists said Wednesday at the United Nations.

The world is falling off track on ambitious global development goals adopted by U.N. members, a panel of scientists said in an independent assessment report released at U.N. headquarters.

Member nations unanimously adopted 17 sustainable development goals known as SDGs in 2015, setting out a wide-ranging “to-do” list tackling conflict, hunger, land degradation, gender equality and climate change by 2030.

The bleak assessment report was released ahead of a sustainable-goals summit scheduled at the United Nations this month.

“Overall, the picture is a sobering one,” said Shantanu Mukherjee, policy chief at the U.N. Department of Economic and Social Affairs. “One element of this is increasing inequality. … Another is the pace at which nature is being degraded by human activity, whether it is climate change or biodiversity loss.”

The independent panel of scientists investigated the ways and systems in which humans and the environment are linked and interact, said Peter Messerli of the University of Bern,
Switzerland, the co-chair of the group of scientists.

“These systems are on a very worrying trajectory, threatening the very existence of humanity,” he told reporters. “We have not realized the urgency to act now.”

Countries must put into practice ways to address vast gaps in wealth distribution and access to economic opportunities and technological advances that undermine innovation and economic growth, the report said.

“Each country has to decide,” Jean-Paul Moatti, chief executive of the French Research Institute for Development and one of the scientists who compiled the report.

“This has to be corrected,” he told the Thomson Reuters Foundation.

The report called on nations to focus on food and energy production and distribution, consumption and urban growth to find ways of building sustainable development.

The cost of implementing the global goals has been estimated at $3 trillion a year.

These are not the first grim predictions made for the fate of the goals. Earlier reports have said they were threatened by the persistence of violence, conflict and destabilizing climate
change.
