To Limit The Increase In Temperature, We Need To Increase Our Attempts Manifold: UN

Trump, who has vowed to pull the U.S. out of the Paris agreement, has dismissed that prediction.

The United Nations says all countries must triple efforts to cut greenhouse gas emissions to limit an average global temperature increase to two degrees Celsius by 2030.

The ninth annual U.N. Environmental Program Emissions Gap report released Tuesday says emissions in 2030 could be up to 15 billion tons higher than needed to prevent a more than two degree hike.

The report said emissions in 2030 would need to be 55 percent lower than they were in 2017 to limit the average increase to a safer 1.5 degrees.

The 2015 Paris Agreement calls for limiting a temperature rise to between 1.5 and two degrees.

The report said emissions reached a record high of 53.5 tons in 2017 after three years of decreases.

The report also said the world’s 20 largest economies, the Group of Twenty, are not on track to meet their goals in 2030.

The analysis follows a special report last month by the U.N. Intergovernmental Panel on Climate Change. It concluded that two degrees of warming, once believed to be a safe threshold, would trigger more deadly extreme weather events. The report said limiting the Earth’s temperature rise to 1.5 degrees would require countries to make rapid and unprecedented changes.

“If the IPCC report represented a global fire alarm, this report is the arson investigation,” said UNEP deputy executive director Joyce Msuya. “The science is clear; for all the ambitious climate action we have seen, government’s need to move faster and with greater urgency. We are feeding this fire while the means to extinguish it are within reach.”

Friday, U.S. President Donald Trump’s administration issued The National Climate Assessment, which predicts climate change could cost the U.S. hundreds of billions of dollars annually through the end of the century.

Trump, who has vowed to pull the U.S. out of the Paris agreement, has dismissed that prediction, telling a reporter Friday, “I don’t believe it. No, no, I don’t believe it.”

World’s First Green Concrete Being Used in a Road Trial in Sydney

 In a world’s first, ‘green’ concrete” which is made using industrial waste from coal-fired power stations and steel manufacturing is being used in a road trial in Sydney.

Researchers from the University of New South Wales, Sydney and research and innovation hub called CRC for Low Carbon Living (CRCLCL) would use results from the trial to create the first set of industry guidelines for “geopolymer” concrete.

Nine sensors have been positioned under the concrete to monitor and compare how the ‘geopolymer’ concrete performs.

“Projects like this geopolymer trial can result in new products that make a real difference in slashing carbon emissions.

“Local governments are responsible for maintaining local roads, so if we can purchase more environmentally sustainable materials, we can fight climate change,” said Lord Mayor Clover Moore.

Made from fly ash and blast furnace slag, ‘geopolymer’ generates just 300 kgs of CO2 per tonne of cement, compared with the 900 km from traditional cement production — saving the equivalent of the electricity used by an average household every two weeks.

The low-CO2 concrete has the potential to put the 400 million cubic tonnes of globally documented waste from the coal and steel industries to good use.

UNSW Sydney researchers will monitor the road performance for up to five years.

“Research into geopolymer has been undertaken since the ’90s, but it’s only now that it’s starting to be commercialised,” said Professor Stephen Foster, Head of the School of Civil and Environmental Engineering at UNSW Sydney.

Concrete contributes 7 per cent of all greenhouse gas emissions and in 2018, the world produced about 4.1 billion tonnes of cement which contributed about 3.5 billion tonnes of CO2.

“Low-CO2 concrete materials offer potential benefits in reducing the greenhouse gas emissions associated with conventional concrete,” said Professor Foster. (IANS)
