June 2023-Climate Change-Record Heat-Air Quqlity

June Marked by Record U.S. Heat Waves, Severe Weather

June 2023 was record hot for some parts of the U.S., while other locations were roiled by severe weather and poor air quality, according to NOAA’s National Centers for Environmental Information. Heat waves led to record high temperatures in Puerto Rico, the Northeast, Mid-Atlantic, Great Lakes, Texas, and Louisiana.

Thick smoke from Canadian wildfires created air quality issues for millions of people in portions of the Northeast and Great Lakes this June. On June 7, around 100 million people across 16 states were under air quality alerts while New York City reported the worst air quality of major cities worldwide. According to the July 4 U.S. Drought Monitor report, about 27.0% of the contiguous U.S. was in drought, up about 8.0% from the end of May. Most of the drought expansion took place in the Midwest, Texas, and the South.

Highlights from “Assessing the U.S. Climate in June 2023” from NOAA National Centers for Environmental Information

  • Heat waves impacted the southern Plains, Northeast and Puerto Rico this month, breaking temperature records and creating life-threatening conditions.
  • In June, the average temperature and precipitation for the contiguous U.S. ranked in the middle third of the historical record.
  • A total of 12 billion-dollar weather and climate disasters have been confirmed this year. These disasters consisted of 10 severe storm events, one winter storm and one flooding event.
  • Thick smoke from Canadian wildfires created air quality issues for millions in portions of the Northeast and Great Lakes this June.
  • Portions of the Midwest experienced dry soils, low streamflows and distressed crops in June. Missouri, Illinois, Wisconsin and Michigan each ranked in the top-10 driest June on record.

 

Temperature – ‘Record Hot’

The average temperature of the contiguous U.S. in June was 69.0°F, 0.5°F above average, ranking in the middle third of the 129-year record. Generally, June temperatures were below average from California to the central Plains and across much of the Mid-Atlantic and Southeast.

Temperatures were above average from the Northwest to the northern Plains, as well as in the southern Plains and Florida Peninsula. North Dakota ranked third warmest on record for June while two additional states ranked among their top-10 warmest on record. Conversely, West Virginia and Virginia had their ninth- and 10th-coldest June on record, respectively.

The Alaska statewide June temperature was 50.0°F, 0.8°F above the long-term average, ranking in the middle third of the 99-year period of record for the state. Above-normal temperatures were observed across the Aleutians and in parts of the North Slope and the Southeast during the month while small pockets of below-average temperatures were observed in interior portions of the state.

Precipitation

June precipitation for the contiguous U.S. was 2.85 inches, 0.08 inch below average, ranking in the middle third of the historical record. Precipitation was above average across much of the West and in parts of the Southeast and New England.

Precipitation was below average across much of the Midwest and in parts of the Northwest, Southwest, southern Plains, Mid-Atlantic and southern New England. Wisconsin and Michigan each had their fifth-driest June on record, while two additional states had their top-10 driest June on record. Conversely, Wyoming ranked third wettest with two additional states ranking among their top-10 wettest June on record.

Across the state of Alaska, the average monthly precipitation was 2.85 inches, making last month the 19th-wettest June in the 99-year record. Conditions were wetter than average across most of the state while parts of the Northeast, Southwest and Panhandle were near normal and parts of the Southeast Interior and Aleutians observed below-normal precipitation during the month.

Billion-Dollar Disasters

Three new billion-dollar weather and climate disasters were confirmed this month, two of which occurred during the month of May. All of these disasters were severe storm events.

For 2023 to-date, 12 weather and climate disasters have losses exceeding $1 billion. These disasters consisted of 10 severe storm events, one winter storm and one flooding event. The total cost of these events exceeds $32.7 billion (CPI-adjusted), and they have resulted in 100 direct and indirect fatalities. For this year-to-date period, the first six months of 2023 rank second-highest for disaster count, behind 2017 with 14 disasters and behind 2021 which had $42.5 billion in terms of total cost.

Meteorologists say Earth Sizzled to a Global Heat Record in June and July Has Been Getting Hotter

An already warming Earth steamed to its hottest June on record, smashing the old global mark by nearly a quarter of a degree (0.13 degrees Celsius), with global oceans setting temperature records for the third straight month, the U.S. National Oceanic and Atmospheric Administration announced Thursday.

June’s 61.79 degrees (16.55 degrees Celsius) global average was 1.89 degrees (1.05 degrees Celsius) above the 20th Century average, the first time globally a summer month was more than a degree Celsius hotter than normal, according to NOAA

OC Grand Jury Report on Drought Conditions Endorses Doheny Desalination Plant, Calls for New Water Sources

South Orange County’s reliance on imported water through unsustainable sources that will be impacted by climate change must adapt, according to the Orange County Grand Jury, which endorsed desalination plants as a solution in a recent report.

Released in early June, the report highlighted the continued existence of drought conditions in the western United States, Orange County water suppliers’ need to find solutions to growing needs and potential shortages, and the importance of conservation and public education.

El Niño Increases Global Health Threats That Require a One Health Response

According to the National Oceanic and Atmospheric Administration (NOAA), El Niño is here. Its arrival likely augurs an increased occurrence of health threats around the world. Brought on by deviations in sea-surface temperatures, El Niño negatively impacts human, animal, and plant health—and their interconnections. According to the World Health Organization (WHO), the changing atmospheric conditions brought on by El Niño will increase the risks for droughts, fires, floods, and storms that can lead to the increased incidence of vector-borne diseases, food insecurity, and heat stress, among other health threats.

Humans’ Impact On the Earth Began a New Epoch in the 1950s Called the Anthropocene, Scientists Say

From climate change to species loss and pollution, humans have etched their impact on the Earth with such strength and permanence since the middle of the 20th century that a special team of scientists says a new geologic epoch began then.

Called the Anthropocene — and derived from the Greek terms for “human” and “new” — this epoch started sometime between 1950 and 1954, according to the scientists. While there is evidence worldwide that captures the impact of burning fossil fuels, detonating nuclear weapons and dumping fertilizers and plastics on land and in waterways, the scientists are proposing a small but deep lake outside of Toronto, Canada — Crawford Lake — to place a historic marker.

Newsom Signs Bills to Speed up Infrastructure Projects

California Governor Gavin Newsom signed a package of bills Monday aimed at streamlining the construction of solar and wind farms, reservoirs, bridges, railways and other infrastructure projects in the Golden State.

Deadly Flooding is Hitting Several Countries at Once. Scientists Say This Will Only Be More Common

Schools in New Delhi were forced to close Monday after heavy monsoon rains battered the Indian capital, with landslides and flash floods killing at least 15 people over the last three days. Farther north, the overflowing Beas River swept vehicles downstream as it flooded neighborhoods. In Japan, torrential rain pounded the southwest, causing floods and mudslides that left two people dead and at least six others missing Monday.

Meet the Colorado River’s Newest – and Youngest – Power Player

California’s Imperial Valley is one of the few places where a 95 degree day can be described as unseasonably cool.

In the shade of a sissoo tree, with a dry breeze rustling its leaves, JB Hamby called the weather “pretty nice” for mid-June. Over his shoulder, sprinklers ticked away over a field of onions. Every few minutes, a tractor rumbled across the broiling asphalt of a nearby road.

Hamby is a water policy bigwig, especially around these parts. He helps shape policies that define how water is used by arguably the most influential water users along the Colorado River. Hamby holds two jobs – he serves on the board of directors for the Imperial Irrigation District (IID) and was recently appointed to be California’s top water negotiator.

And he’s only 27 years old.

Northwest Drinking Water Concerns Could Get Worse as the Climate Changes

Thunderstorms high in the Cascades recently stirred up a lot of dirt in a central Washington river, causing problems for people on its banks.

All the dirt in the Naches River was too much for the city of Yakima’s water treatment plant to handle. Cities and towns could see situations like this happen more often as the climate continues to change.

Climate change will cause more storm runoff, change when snowpack melts and lead to more severe wildfires and harmful algal blooms, said Amanda Hohner. She studies how post-wildfire runoff affects drinking water treatment plants.

“At least in the Western U.S., the effects of wildfire and also climate change are really starting to challenge drinking water treatment plants, resulting in different water quality than maybe those water treatment plants were designed for,” Hohner said.

World Hits Record Land, Sea Temperatures as Climate Change Fuels 2023 Extremes

The target of keeping long-term global warming within 2.7 Fahrenheit is moving out of reach, climate experts say, with nations failing to set more ambitious goals despite months of record-breaking heat on land and sea.

As envoys gathered in Bonn in early June to prepare for this year’s annual climate talks in November, average global surface air temperatures were more than 2.7F above pre-industrial levels for several days, the EU-funded Copernicus Climate Change Service said.

Though mean temperatures had temporarily breached the 2.7F threshold before, this was the first time they had done so in the northern hemisphere summer that starts on June 1. Sea temperatures also broke April and May records.

“We’ve run out of time because change takes time,” said Sarah Perkins-Kirkpatrick, a climatologist at Australia’s University of New South Wales.
