Climate change and global warming 2020

[mikewhitney]

Too much CO2 also insulates the atmosphere and prevents heat from escaping, basic science = global warming.

OR, as says shows, CO2 increases after the global temperature increases. But for global warming, we have to put away what is truthful so that we can follow the scare policy. It is a government-funded fairy tale designed to scare the youth. When people are in fear they will take solutions that in fact are irrational.

OR, as says shows, CO2 increases after the global temperature increases.

It's largely a myth that CO2 generally lags temperature, that happens only for the early parts of the ten thousand year long Milankovich cycle. And we're not in at the start of one of those now.

But for global warming, we have to put away what is truthful so that we can follow the scare policy. It is a government-funded fairy tale designed to scare the youth. When people are in fear they will take solutions that in fact are irrational.

No, it's pretty much just the conclusions of the Scientific Community, the foundation of was laid as far back as in the thirties when models of how infrared radiation interacted with the atmosphere was laid, it became a serious study in the seventies, it was pretty much solidified at the turn of the millennium and nothing has changed the basic conclusion or model.

The above bold is true and results in global warming.

Again you are into anti-science conspiracy mythology. The global warming is based on the evidence and sound science.

Whether this year is the hottest on record or the close second hottest the trends over time demonstrate a potential devastating future.

2020 is on course to be the warmest year on record
While this year will be memorable for many reasons, it is now more likely than not that 2020 will also be the warmest year for the Earth’s surface since reliable records began in the mid-1800s.

This is all the more remarkable because it will lack any major methane, and nitrous oxide – in the atmosphere. Arctic sea ice extent was at record low levels for much of the summer and the summer minimum clocked in as the second lowest on record after 2012.

While climate records are a useful benchmark to highlight the warming of the planet, the change in temperatures, sea ice and other climate factors over time are much more important than if any single year sets a new record.

There has been a clear warming trend over the past 50 years, along with hints in some datasets of potential acceleration in recent years. Similarly, both sea ice extent and volume are clearly declining over time.

Surface temperatures show record warmth

The first nine months of 2020 were remarkably warm. Carbon Brief has analyzed records from six different research groups that report global surface temperature records: NASA; NOAA; Met Office Hadley Centre/UEA; Berkeley Earth; Cowtan and Way; and Copernicus/ECMWF.

The figure below shows the temperature anomalies – changes relative to the 1981-2010 average temperature – for each year since 1970, along with the average over the first nine months of 2020. (Note: at the time of writing, September data was not yet available for the Hadley/UEA or Cowtan and Way temperature records.)

Expect More Mega-Droughts – Droughts That Last Two Decades or Longer



Mega-droughts – droughts that last two decades or longer – are tipped to increase thanks to climate change, according to University of Queensland-led research.

UQ’s Professor Hamish McGowan said the findings, which are published in Nature Scientific ReportsScientific Reports.

Ice sheet uncertainties could mean sea level will rise more than predicted

by Imperial College London

Sea level could rise higher than current estimates by 2100 if climate change is unchallenged, according to a new assessment.

Its authors say understanding the way strong global heating affects polar ice sheets will be crucial to projecting sea level rise over the next century. However, uncertainties remain and current knowledge about ice sheets suggests sea-level rise under continued strong warming could be higher than the Intergovernmental Panel on Climate Change (IPCC) 'likely' range by 2100.

The authors of the study, published today in the journal One Earth, also suggest ways scientists can make predictions more certain, by improving our understanding of ice-sheet

Update soon on whether this year is the warmest or the second warmest.
