CO2 is not pollution

Everyone knows that won’t happen. Too expensive, and no adequate methods available anyway even if it was a good idea, which it isn’t. Nobody consults the growers and planters of the world, it seems. Little or no role is allocated to natural climate variation, but that’s only one of many issues.

Sucking carbon dioxide out of the atmosphere is the world’s only chance to avoid climate change disaster, according to a report due to be released Monday.
The paper by the United Nations’ Intergovernmental Panel on Climate Change (IPCC) is expected to say that dangerous climate change will be avoided only if vast quantities of carbon dioxide are removed from the air, the Times of London reported.
“Carbon dioxide removal is necessary to achieve net-zero greenhouse gas emissions globally and nationally,” a draft version of the summary report said, according to The Times. If “negative emission” technologies fulfill their potential, it continues, they could even enable a reversal of global warming.
However, carbon-capturing technology is nowhere near where it needs to be. Today, 19 operational plants capture only 10,000 tons of carbon dioxide a year, compared to the 36 billion tons the world produces annually, according to the report.
The paper also says that an urgent and wholesale shift away from fossil fuels is needed for there to be any chance of limiting global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels.
Scientists believe topping that threshold will lead to significant and irreversible harm to Earth’s climate.
But the report, commissioned and endorsed by 195 governments, acknowledges that the only “negative emissions” strategy currently used on a mass scale is tree planting.
Scientists are working on other techniques, including air capture or giant fans extracting carbon dioxide from the air and storing it underground or converting it into jet fuel.
