Summer 2019 in the Northern Hemisphere tied for warmest summer on record – Five hottest NH summers have occurred in the past five years

By Andrew Freedman 16 September 2019 (The Washington Post) – The Northern Hemisphere just had its hottest summer on record since 1880, according to National Oceanic and Atmospheric Administration data released Monday. NOAA found the average global surface temperature taken by thousands of thermometers, buoys and other sensors on land and sea tied with that of 2016 […]

In agency-wide email, NOAA chief moves to regain scientists’ trust after defending incorrect Trump tweet

By Jason Samenow 13 September 2019 (The Washington Post) – Neil Jacobs, the acting head of the National Oceanic and Atmospheric Administration, sent an all-staff email Friday afternoon in an apparent effort to repair damage from an unusual 6 September 2019 statement that sided with President Trump rather than agency weather forecasters. The controversial NOAA […]

Hawaii was surrounded by waters with warmer-than-average sea surface temperatures on 9 September 2019. Departures from the seasonal norm are shown in degrees Celsius. On this date, Lihue, Kauai observed its 17th consecutive day of a daily record high temperature being set or tied. This is likely the longest such stretch for any official weather station with a long period of record (more than 50 years) at any site in the U.S. climate database. Graphic: Tropical Tidbits

Hawaii’s warmest summer on record and Alaska’s second warmest in 2019

By Christopher C. Burt 10 September 2019 (Weather Underground) – Although 2800 miles of open ocean separate them, both Anchorage, Alaska and Honolulu, Hawaii experienced their warmest climatological summers (June-August) on record this year. It appears that this was Alaska’s second warmest summer (following that of 2004) but it is likely that it was Hawaii’s […]

National Weather Service director Louis Uccellini led a standing ovation in the agency’s office in Birmingham, Alabama, for weather forecasters who corrected Trump when he falsely claimed Hurricane Dorian was set to hit Alabama. Speaking at an annual meeting of the National Weather Association on 9 September 2019, Uccellini praised the scientists for upholding "the integrity of the forecasting process." Photo: Rick Smith

July 2019 was Earth’s hottest month in recorded history – 2019 almost certain to be among the five warmest years on record

By Dr. Jeff Masters 15 August 2019 (Weather Underground) – July 2019 was the planet’s warmest July and warmest month in absolute terms since record keeping began in 1880, said NOAA’s National Centers for Environmental Information (NCEI) on Thursday. Earth’s previous warmest month on record was July 2016. The Japan Meteorological Agency (JMA) rated July 2019 in a […]

State of the Climate in 2018: 2018 was the fourth-hottest year on record, behind 2016, 2015, and 2017

12 August 2019 (NCEI) – A new State of the Climate report [pdf] confirmed that 2018 was the fourth warmest year in records dating to the mid-1800s. Last year was the fourth warmest year on record despite La Niña conditions early in the year and the lack of a short-term warming El Niño influence until […]

Nutrient loading lowers resistance to thermal stress in Florida Keys corals – “These data make clear that this is not an ‘either temperature or nutrients’ situation, but rather a ‘both/and’ combination of multiple stressors”

By Gisele Galoustian 15 July 2019 (FAU) – Coral reefs are considered one of the most threatened ecosystems on the planet and are dying at alarming rates around the world. Scientists attribute coral bleaching and ultimately massive coral death to a number of environmental stressors, in particular, warming water temperatures due to climate change. A […]

Warming Arctic permafrost releasing 12 times more nitrous oxide, a potent greenhouse gas, than previously thought – “This needs to be taken more seriously than it is right now”

By Caitlin McDermott-Murphy 6 June 2019 (The Harvard Gazette) – About a quarter of the Northern Hemisphere is covered in permafrost. Now, it turns out these permanently frozen beds of soil, rock, and sediment are actually not so permanent: They’re thawing at an increasing rate. Human-induced climate change is warming these lands, melting the ice […]

Wettest 12 months in U.S. history, again – “The last twelve months beat the previous record, set just a month ago, by a full 1.48 inches”

By Bob Henson 6 June 2019 (Weather Underground) – Propelled by a two-week siege of widespread severe weather and heavy rain in late May, the contiguous U.S. has once again broken its record for the wettest year-long span in data going back to 1895. According to the monthly U.S. climate summary released Thursday from the […]
