Good morning bloggers,
Kansas City set the record for the earliest accumulation in recorded history last night with 0.2″ at KCI Airport. There is a FREEZE WARNING for tonight. There likely will not be a hard freeze. Conditions are favorable for heavy frost early Tuesday morning. There was too much of a breeze this morning for frost to form, and now with light winds tonight, we will likely have the heavy frost on Tuesday morning. Then, there is a big warm up, and the weather looks dry and a bit cool next Sunday night for the big Chiefs home game against the Bengals. Last night was a good night in the loss at New England. Our young superstar grew up some more. We have some exciting years ahead, and this year may still be magical, so take a deep breath.
Speaking of taking a deep breath, I titled this blog State of the climate in 2017, and I am going to share with you what scientists have put together in the Bulletin of the American Meteorological Society here. It will open up a big debate. Where are the facts? I see them as this current warming of the earth being directly related to the increase in CO2 in the atmosphere. Yes, the facts lean strongly in the direction that this is a man made warming. This is not my opinion, although I lean in this direction. Take a look:
STATE OF THE CLIMATE IN 2017 (from the special supplement to the Bulletin of the American Meteorological Society, Vol. 99, No. 8, August 2018)
“In 2017, the dominant greenhouse gases released into Earth’s atmosphere-carbon dioxide, methane, and nitrous oxide-reached new record highs. The annual global average carbon dioxide concentration at Earth’s surface for 2017 was 405.0 +/- 0.1 ppm, 2.2 ppm greater than for 2016 and the highest in the modern atmospheric measurement record and in ice core records dating back as far as 800,000 years. The global growth rate of CO2 has nearly quadrupled since the early 1960s.
With ENSO-neutral conditions present in the central and eastern equatorial Pacific Ocean during most fo the year and weak La Niña conditions notable at the start and end, the global temperature across land and ocean surfaces ranges as the second or third highest, depending on the dataset, since records began in the mid-to-late 1800s. Notably, it was the warmest non-El Niño year in the instrumental record. Above Earth’s surface, the annual lower troposhperic temperature was also either second or third highest according to all datasets analyzed. The lower stratospheric temperature was about 0.2°C higher than the record cold temperature of 2016 according to most of the in situ and satellite data sets.
Several countries, including Argentina, Uruguay, Spain,and Bulgaria, reported record high annual temperatures. Mexico broke its annual record for the fourth consecutive year. On 27 January, the temperature reached 43.4°C at Puerto Madrid, (43°) anywhere in the world. On 28 May in Turbat, western Pakistan, the high of 53.5°C tied Pakistan’s all-time highest temperature for May.
In the Arctic, the 2017 land surface temperature was 1.6°C above the 1981-2010 average, the second highest since the record began in 1900, behind only 2016. The five highest annual Arctic temperatures have all occurred since 2007. Exceptionally high temperatures were observed in the permafrost across the Arctic, with record values reported in much of Alaska and northwestern Canada. In August, high sea surface temperature (SST) records were broken for the Chukchi Sea, with some regions as warm as +11°C or 3° to 4°C warmer than the long-term mean (1982-present). According to paleoclimate studies, today’s abnormally warm Arctic air and SSTs have not been observed in the last 2000 years. The increasing temperatures have led to decreasing Arctic sea ice extent and thickness. On 7 March, sea ice extent at the end of the growth season saw its lowest maximum in the 37-year satellite record, covering 8% less area than the 1981-2010 average. The Arctic sea ice minimum on 13 September was the eighth lowest on record and covered 25% less area than the long-term mean.
Preliminary data indicate that glaciers across the world lost mass for the 38th consecutive year on record; the declines are remarkably consistent from region to region. Cumulatively since 1980, this loss is equivalent to slicing 22 meters off the top of the average glacier.
Antarctic sea ice extent remained below average for all of 2017, with record lows during the first four months. Over the continent, the austral summer seasonal melt extent and melt index were the second highest since 2005, mostly due to strong positive anomalies of air temperature over most of the west Antarctic coast. In contrast, the East Antarctic Plateau also distinguished by the second smallest Antarctic ozone hole observed since 1988.
Across the global oceans, the overall long-term SST warming trend remained strong. Although SST cooled slightly from 2016 to 2017, the last three years produced the three highest annual values observed; these high anomalies have been associated with widespread coral bleaching. The most recent global coral bleaching lasted three full years, June 2014 to May 2017, and was the longest, most widespread, and almost certainly most destructive such even on record. Global integrals of 0-700-mand 0-2000-m ocean heat content reached record highs in 2017, and global mean sea level during the year became the highest annual average in the 25-year satellite altimetry record, rising to 77 mm above the 1993 average.
In the tropics, 2017 saw 85 named tropical storms, slightly above the 1981-2010 average of 82. The North Atlantic basin was the only basin that featured an above-normal season, its seventh most active in the 164-year record. Three hurricanes in the basin were especially notable. Harvey produced record rainfall totals in areas of Texas and Louisiana, including a storm total of 1538.7 mm near Beaumont, Texas, which far exceeds the previous known U.S. tropical cyclone record of 1320.8 mm. Irma was the strongest tropical cyclone globally in 2017 and the strongest Atlantic hurricane outside of the Gulf of Mexico and Caribbean on record with maximum winds of 295 kmh/h. Maria caused catastrophic destruction across the Caribbean Islands, including devastating wind damage and flooding across Puerto Rico. Elsewhere, the western North Pacific, South Indian, and Australian basins were all particularly quiet.
Precipitation over global land areas in 2017 was clearly above the long-term average. Among noteworthy regional precipitation records in 2017, Russia reported its second wettest year on record (after 2013) and Norway experienced its sixth wettest year since records began in 1900. Across India, heavy rain and flood-related incidents during the monsoon season claimed around 800 lives. In August and September, above-normal precipitation triggers the most devastating floods in more than a decade in the Venezuelan states of Bolivar and Delta Amacuro. In Nigeria, heavy rain during August and September caused the Niger and Benue Rivers to overflow, bringing floods that displaced more than 100,o00 people.
Global fire activity was the lowest since at least 2003; however, high activity occurred in parts of North America, South America, and Europe, with an unusually long season in Spain and Portugal, which had their second and third driest years on record, respectively. Devastating fires impacted British Columbia, destroying 1.2 million hectares of timber, bush, and grassland, due in part to the region’s driest summer on record. In the United States, and extremely western wildfire season burned over 4 million hectares; the total costs of $18billion tripled the previous U.S. annual wildfire cost record set in 1991.”
This is the abstract to the full publication! The earth has been warming. What is the cause? Is it a natural occurrence, or a major influence by manmade greenhouse gases increasing in the atmosphere, albeit small amounts. The direct relationship from the current warming to the increased greenhouse gases must be seriously considered and the evidence and facts point in the direction of this warming being manmade.
Have a great day. We will look into the cycling pattern on 41 Action News tonight. Go over to the Weather2020 blog to join in the conversation.
