UN Climate report- record emissions’ - Govt' must use rail
Friday 29th November 2019,
Quote; “Levels of the three main heat-trapping gases emitted into the atmosphere – carbon dioxide (CO2), methane, and nitrous oxide – have reached yet another high, the UN meteorological agency, WMO, said on Monday.
In an appeal to Governments to do more to reverse countries’ reliance on producing energy from fossil fuels, in line with the 2015 Paris Agreement on Climate Change, WMO Secretary-General Petteri Taalas, warned that “the future welfare of mankind” was at stake.
“We have again broken records in carbon dioxide concentrations and we have already exceeded 400ppm level which was regarded as a critical level,” he said, in reference to the 407.8 parts per million reading for 2018. “That happened already two years ago and this carbon dioxide concentration continues and continues, and last year’s increase was about the same as we have been observing in the past 10 years, as an average.”
According to the World Meteorological Organization’s Greenhouse Gas Bulletin, since 1990, so-called “long-lived” greenhouse gases have caused a 43 per cent increase in total radiative forcing - the warming effect on the climate.
Of these gases, CO2 accounts for about 80 per cent, according to the United States’ National Oceanic and Atmospheric Administration (NOAA), whose data is quoted in the WMO Bulletin.
Carbon dioxide especially damaging
CO2 is particularly harmful in a global warming context because it remains in the atmosphere for centuries and in the oceans for even longer, the agency explained.
Professor Taalas noted too that when the Earth last had similar concentrations of CO2, the temperature “was 2-3 degrees Celsius warmer (and) sea level was 10-20 metres higher than now”.
Turning to methane, which is responsible for 17 per cent of radiative forcing, Professor Taalas noted that “we have also been breaking records”, since last year’s increase “was the second-highest in the last 10 years”.
According to the WMO bulletin, global readings indicate that atmospheric methane (CH4) reached a new high of 1,869 parts per billion (ppb) in 2018, more than two and a half times the pre-industrial level.
Approximately 40 per cent of methane comes from natural sources, such as wetlands and termites, but 60 per cent comes from human activities, including cattle breeding, paddyfields, mines, landfills and biomass burning.
“For CH4, the increase from 2017 to 2018 was higher than both that observed from 2016 to 2017 and the average over the last decade,” the bulletin noted.
Gas concentrations accelerating
This upwards trend in emissions was repeated in the case of nitrous oxide (N2O), with concentrations in 2018 estimated at 331.1 ppb, or 123 per cent above pre-industrial levels.
“Nitrous oxide has contributed about six per cent of the warming so far”, said Professor Taalas. “It’s very much coming from farmlands and again there we have been breaking records, the steady growth of N2O concentration still continues.”
Based on current data, global emissions are not estimated to peak by 2030, let alone by 2020, if existing climate policies - as set out in countries’ Nationally Determined Contributions (NDCs) - remain unchanged, WMO believes.
This demonstrates that global perspective and strategy is needed to solve this problem, Professor Taalas said. The European Union or USA, or China, can’t solve it alone, “you have to have all of the countries involved.”
While Governments understand that this is a challenge, so too does the private sector, he added, noting that it was “more and more interested in finding solutions”.
FACT; This latest UN climate change report shows we are now heading for a global catastrophe – and now it’s time to act;
CEAC reported on 27th November in a press release “NZTA lack respect of environmental stewardship” https://www.scoop.co.nz/stories/PO1911/S00332/nzta-lack-respect-of-environmental-stewardship.htm
• that “Living near a busy road can stunt children's lung growth, a UK report has shown below.”
• Quote; Children's health was found to be affected by staying within 50 metres of the road.
• The study recorded the effect of roadside pollution across 13 cities in the UK and Poland.
Fact; Government now have seen the increased ‘busy road’ traffic is now harming our children’s health.
Fact; Since this latest UN climate change report clearly shows; we are now heading for a global catastrophe – and now it’s time to act;
CEAC calls on Government to use low emissions rail freight and passenger services to lower climate emissions and lower ‘busy roads’ harming us all at the same time.
Rail transport is a win – win for every citizen, business and the planet..
CEAC encourage to see a Government who is caring, considerate inclusive and responsive to citizens’ health and wellbeing concerns.
