snoop1130 Posted January 24, 2020 Share Posted January 24, 2020 Australia bushfires contribute to big rise in global CO2 levels - UK's Met Office By Matthew Green FILE PHOTO: The sun struggles through the clouds as high winds push smoke and ash from the Currowan Fire towards Nowra, New South Wales, Australia January 4, 2020. REUTERS/Tracey Nearmy LONDON (Reuters) - Australia’s bushfires are contributing to one of the biggest annual increases in the concentration of carbon dioxide in the Earth’s atmosphere since record-keeping began more than 60 years ago, according to a forecast published by Britain’s Met Office on Friday. While human-caused greenhouse gas emissions are responsible for the bulk of the increase in CO2 levels, Australia’s bushfires have made the problem measurably worse, underscoring the impact of the catastrophe on the global climate system. “A forecast of the atmospheric concentration of carbon-dioxide shows that 2020 will witness one of the largest annual rises in concentration since measurements began at Mauna Loa, in Hawaii, 1958,” the Met Office said in a statement. It said the atmospheric concentration of CO2 is expected to peak above 417 parts per million in May, with the average for the year forecast to be 414.2 ± 0.6ppm. This annual average represents a 2.74 ± 0.57 ppm rise on the 2019 average. Concentrations of CO2 in the Earth’s atmosphere have already far surpassed what scientists consider to be safe limits. At a climate summit in Madrid in December, U.N. Secretary-General Antonio Guterres warned that 400 ppm had once been considered “an unthinkable tipping point.” The last time there was a comparable concentration of CO2 in the atmosphere was between 3 and 5 million years ago, when the temperature was between 2 and 3 degrees Celsius warmer and sea levels were 10 to 20 metres higher than today, scientists say. Although the data series started in 1958 has always shown CO2 concentrations increasing year-on-year, driven by fossil fuel burning and deforestation, the rate of rise has not been perfectly even, the Met Office said. Fluctations in the amount of CO2 absorbed by tropical forests and other natural carbon sinks can affect overall levels of the gas in the atmosphere. “Overall these are expected to be weaker than normal for a second year running,” said Richard Betts, of the Met Office Hadley Centre and University of Exeter. This year, the Met forecasts that the impact of weather patterns on global ecosystems will increase the annual human-caused rise in CO2 concentration by 10%, with emissions from the Australian fires accounting for one-fifth of that increase. Australia’s fires are themselves a foretaste of the kind of catastrophes that are liable to become normal as the planet warms, with prolonged drought and low humidity making arid landscapes more vulnerable to huge blazes, scientists say. The CO2 forecast underscored the urgency of the task facing negotiators trying to persuade big countries to cut emissions under the 2015 Paris Agreement to combat climate change, which is still nowhere near on track to spare the world from devastating temperature increases. The accord enters a crucial implementation phase this year, with governments due to submit more ambitious plans for climate action ahead of a summit in Glasgow in November. Australia’s government is regarded as among the main laggards. Last month, the 2020 Climate Change Performance Index rated Australia as one of the worst performers among 57 high-emitters, awarding it 0 out of 100 possible points for its policies. -- © Copyright Reuters 2020-01-24 Follow Thaivisa on LINE for breaking Thailand news and visa info 1 Link to comment Share on other sites More sharing options...

Please read below: https://www.climate.news/2019-04-26-nasa-declares-carbon-dioxide-is-greening-the-earth.html yes, the plants have been starving for hundreds of millions of years due to a continuous depletion of co2 in the atmosphere, and they are still starving albeit no longer at the brink of extinction. still, as critical as this is, we should have a comfortable safety margin. a simple extrapolation of this trend is that without man recycling back co2 back into atmosphere where it belong will inevitably end in end of plant life in another 2 million years, and with it all other life forms up the food chain 2 Link to comment Share on other sites More sharing options...

bristolboy Posted January 24, 2020 Share Posted January 24, 2020 As per usual, what denialists seem incapable of understanding is that rate matters. I just wonder if in their financial affairs they are similarly incapable of understanding the difference high interest rates make to loans and investments. Another point they seem incapable of assimilating is that more isn't necessarily better. 4 hours ago, VocalNeal said: Oh dear this will not be popular?

Aspaltso Posted January 25, 2020 Share Posted January 25, 2020 We are all just going to have to deal with the consequences of allowing so much carbon into our atmosphere. That includes dealing with this years drought, this years water shortage. Flooding rains which we had in Issan both in 2017, and this past year. We are well beyond the debate as to whether climate change exists. Now its time to deal with it. 1 Link to comment Share on other sites More sharing options...

Nonsense You got any evidence for that? Do you even know what "order of magnitude means?" Let me give you a hint: If two numbers differ by one order of magnitude, one is about ten times larger than the other. If they differ by two orders of magnitude, they differ by a factor of about 100. Two numbers of the same order of magnitude have roughly the same scale: the larger value is less than ten times the smaller value. https://simple.wikipedia.org/wiki/Order_of_magnitude Link to comment Share on other sites More sharing options...

More is most certainly not, always better.... far from it. “More” often involves increased risk around design and implementation, making “more”, worse.... you know, like too many cooks spoiling the broth. meanwhile... 10 is most certainly not a common safety factor in construction. Far from it. Safety factors vary for various things for various reasons. and 1500ppm as a suggestion? Sure, it may help some plants, But I really think the greenies are more concerned about human habitation of the planet, than continued tree life, and these ultra high co2 levels provide issues for the existence of human life if “save the planet, kill the people” is your premise in discussing CO2 levels... your on track.
