New government data released Monday revealed that the U.S. has already experienced more billion-dollar weather disasters in 2023 than in any other year since authorities started tracking such data 40-plus years ago.
Two projects led by researchers from UC San Diego’s Scripps Institution of Oceanography have been awarded nearly $2.5 million by the National Oceanic and Atmospheric Administration (NOAA) to probe the potential of climate change solutions aimed at fighting ocean acidification and removing planet-warming carbon dioxide from the atmosphere.
Across the western U.S., many areas received record or near-record amounts of snowpack over the winter. With the spring and summer temperatures melting the abundant snow, a record volume of streamflow has been recorded in several basins in the southwestern U.S., providing more water for the area later into the summer than is typically seen.
The Walker and Carson basins near the California-Nevada border, for example, have reported the largest volume of streamflow for April through July that has ever been observed in roughly a century, when the records began. The ample runoff is helping fill reservoirs that have been depleted from years of drought conditions.
Dry conditions dominated the West and southern Plains, coupled with above-normal temperatures. Precipitation was most widespread throughout much of the upper Midwest and central Plains and into the Northeast. Almost the entire country had near- to above-normal temperatures this last week, with the greatest departures over the Southwest and central Plains where temperatures were at least 4-7 degrees above normal.
Cooler-than-normal temperatures were recorded in the Pacific Northwest with departures of 3-6 degrees below normal. At the end of the current U.S. Drought Monitor period, significant rains developed over portions of the Midwest and central Plains, and they will be accounted for in the next analysis.
July 2023 recorded more than 6,500 severe weather reports, the most preliminary July reports on record, according to our friends at the @NWSSPC. As we head into August, where is severe weather most likely this time of year? https://t.co/pySvHxoQQt pic.twitter.com/6C4u82SGYa

Central portions of the Intermountain West may be spared degradation, as those areas are still showing residual benefits from above normal winter snowpack leading up to the summer, in addition to periods of above normal rainfall during the last 60 to 90 days. Seasonal temperature and precipitation outlooks, ENSO, and climatology favor widespread drought improvement and removal across the central U.S. However, drought persistence is favored across the Upper Midwest, although there is the potential for localized improvements.” Read full assessment: cpc.ncep.noaa.gov/products/expert_assessment/sdo_summary.php.
Colors show where total precipitation has an increased chance of being higher or lower than usual during the next three months. The darker the shading, the greater the chance for the indicated condition. White areas have equal chances for precipitation totals that are below, near, or above the long-term average (median) for the next three months.
Climate scientists base future climate outlooks on current patterns in the ocean and atmosphere. They examine projections from climate and weather models and consider recent trends. They also check historical records to see how much precipitation fell when patterns were similar in the past.

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.

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.
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.
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.
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.
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
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.
Forecasters with the National Oceanic and Atmospheric Administration (NOAA) last week declared the beginning of an El Niño.
El Niño is marked by warmer-than-average surface water temperatures in the eastern Pacific Ocean, specifically along the equator.
An early bird El Niño has officially formed, likely to be strong, warp weather worldwide and give an already warming Earth an extra kick of natural heat, meteorologists announced.
The National Oceanic and Atmospheric Administration Thursday issued an El Niño advisory, announcing the arrival of the climatic condition. It may not quite be like the others.
El Niño conditions are present and are expected to gradually strengthen into the Northern Hemisphere winter 2023-24. An #ElNino Advisory is now in effect. https://t.co/5zlzaZ0D9Z pic.twitter.com/KEkExCC3Hc

So far, in 2023, seven different weather and climate-related disasters have cost the United States at least $1 billion.
According to the National Oceanic and Atmospheric Administration data dating back to 1980, that is the second-highest number of events on record for the first four months of a year.
