Let’s take a look at the Weather in April 2024 in the U.S. and Globally – Posted on May 20, 2024

Much of the information in this report comes from the monthly emails I receive from John Bateman. He does public outreach for NOAA and in particular NCEI. I could find the same information and more on the NCEI website but John Bateman produces a good summary so I use it or most of it. I also add additional information from NCEI or other NOAA websites. At the end of the article, I provide links that will get you to the full reports and much additional information.

 

Looking at the trend for April over time.

This is the temperature trend for April in CONUS.

But look at this the most recent 25 years.  No increase but a decrease.  Data can be misleading if you do not look at it carefully

The temperature for the world, land and water hit a new record.

The temperature for the world, land only also was  a record.

The temperature for the world’s oceans also hit a record. Notice the slope is less. You can see the impact of ENSO in this graphic.

Looking Back at February 2024 Weather for the U.S. and the World – Posted on March 16, 2024

Much of the information in this report comes from the monthly emails I receive from John Bateman. He does public outreach for NOAA and in particular NCEI. I could find the same information and more on the NCEI website but John Bateman produces a good summary so I use it or most of it. I also add additional information from NCEI or other NOAA websites. At the end of the article, I provide two links that will get you to the full reports and much additional information.

I start with the trends of February Temperature looking at first CONUS, then all of North America and then the World both land and water.

This is the temperature trend for CONUS. There was a decrease for February in 2024 as compared to February in 2023. I show all the data for February starting with 1895.

This is the temperature trend for North America. It covers a larger geographical area but I find it easier to read.

The temperature for the world, land and water hit a new record.

Looking Back at Weather for the U.S. and World in January 2024 Posted on February 20, 2024

Much of the information in this report comes from the monthly emails I receive from John Bateman. He does public outreach for NOAA and in particular NCEI. I could find the same information and more on the NCEI website but John Bateman produces a good summary so I use it or most of it. I also usually add additional information from NCEI or other NOAA websites. The full NCEI report can be accessed HERE.

Arctic air mass brought bitter cold and snow to much of the nation in mid-January
Powerful storms brought heavy rainfall and flooding to parts of the southern Plains

I start with the U.S. Key Points

  • The arctic air mass from January 14–18 broke nearly 2,500 daily minimum temperatures county records from the Northwest to the Lower Mississippi Valley.

  • On January 22–25, heavy rainfall brought more than a month’s worth of rain and life-threatening flooding to parts of Texas and Louisiana.

  • January 2024 was the 10th-wettest January on record for the nation, and temperature ranked in the middle third of the historical record for the month.

And then the Global Key Points

  • Temperatures were above average over much of the globe, but the eastern United States, most of Europe and a few other areas were cooler than average.

  • There is a 22% chance that 2024 will be the warmest year in NOAA’s 175-year record and a 79% chance that El Niño will transition to neutral conditions by mid-year.

  • Northern Hemisphere snow cover was near average, but Antarctic sea ice extent was fifth lowest on record for January.

  • Global precipitation was nearly record-high in January, following on the heels of a record-wet December.

I added the below to what John Bateman provided.

 

January 2024 was a busy month

 

 

This is the temperature trend for CONUS. There was a decrease for January in 2024

 

The temperature for the world, land and water hit a new record, but when looking at land alone it was not a new record.

Looking back at 2023 Weather for the World -Posted on January 15, 2024

Most of the information in this report comes from the monthly email I receive from John Bateman. He does public outreach for NOAA and in particular NCEI. I could find the same information and more on the NCEI website but John produces a good summary so I use it or most of it. I also sometimes add additional information from NCEI or other NOAA websites. The full NCEI report for 2023 can be accessed HERE.

 

 

 

I added the below to what John Bateman provided.

 

2023 was a busy year

 

This is the temperature trend for the world: land and water. There was a big increase in 2923.

 

This is also land and water [corrected previous error) and it is by month and it shows the ENSO state of each month. You can really see that the temperature goes up with the El Nino phase and down with La Nina. It has to do with the releases and absorption of heat by the oceans during the different ENSO Phases. A main reason for that is simple. During La Nina the strong Easterlies along the Pacific skim off the warm surface water is forced into the IndoPacific Warm Pool where it covers a smaller area. When the Easterlies relax during an El Nino the warm water spreads out so the Ocean Surface is warmer. There are other factors also.

 

 

This is just land Globally. It also increased in 2023 but not as much as when including both land and water.

This is for the year but just North America which in not just the U.S. but includes the U.S.   2023 seemed to match but not beat a year about seven years earlier.

 

 

This is December only for North America which includes the U.S. but more than the U.S..  2023 saw a big increase.

This is just the U.S. for December and we have shown this before but you can see that the increase here is less than for North America probably because it does not include Alaska.  I did not include enough graphs to make it easy to figure out but Northern Hemisphere has warmed more than the Southern Hemisphere. It probably has to do with the higher ratio of land to water in the Northern Hemisphere.  When water warms it is not just at the surface so the impact of Global Warming on the surface of water is less than the impact on the surface of land.
Now we will go back to the information in the Bateman email and some readers will have to click on Read More to see the rest of this article.

Looking Back at the weather for the full Year of 2023 in the U.S. Posted January 10, 2024

Most of the information in this report comes from the monthly email I receive from John Bateman. He does public outreach for NOAA and in particular NCEI. I could find the same information and more on the NCEI website but John produces a good summary so I use it or most of it. I also sometimes add additional information from NCEI or other NOAA websites. John Bateman sends me two emails. One on the World situation and one for the U.S.

I probably should have addressed the single month of December before the full year of 2023 but I received this email today so I thought I would write the article tonight for Wednesday viewing.

This article is about the full year of 2023 in the U.S.

This is the U.S. Annual temperature trend. 2023 was by no means a record but it was above the trend line. +0.16F a decade is a fairly steep slope.   You can see some cyclical characteristics in the data but the trend is clear. If I calculated the trend since 1970, the slope would be quite a bit steeper.

Now I will present the information provided by John Bateman with perhaps three additional graphics. Some readers may need to click on “Read More” to access the full article. It is how the Home Page can display the introduction to many articles.

Looking back at November for the World December 19, 2023 – Earth had its Warmest November Ever Since Reliable Data has been Available.

Most of the information in this report comes from the monthly email I receive from John Bateman. He does public outreach for NOAA and in particular NCEI. I could find the same information and more on the NCEI website but John produces a good summary so I use it or most of it. I also sometimes add additional information from NCEI or other NOAA websites. The full NCEI report for November can be accessed HERE.

I added the below to what John Bateman provided.

This November saw a huge jump. Remember this is the data for both land and water.

This looks just at land but the trend is similar.  In fact the regression line is even steeper.

 

This is just North America. It is more than just the U.S.  and the slope of the regression line is even steeper. But for North America, unlike the world, November did not set a new record.

This shows selected anomalies but it mostly covers temperature around the world.

Assessing the U.S. Climate in November 2023 – December 13, 2023

Much of the information in this article comes from the monthly email I receive from John Bateman. He does public outreach for NOAA and in particular NCEI. I could find the same information and more on the NCEI website but John produces a good summary so I use it or most of it. I also sometimes add additional information from NCEI or other NOAA websites. John Bateman sends me two emails. One on the World situation and one for the U.S. One of the things I like to add to what John Bateman sends me is the state ranking maps. These maps show how temperature and precipitation for each state rank relative to the 129 years of what is considered to be the most reliable data we have.

This article is about November 2023 in the U.S.

This trend analysis comes from Climate at a Glance also from NCEI

This is the U.S.  November temperature trend.  This past November was by no means a record but it was above the trend line. It was a relief in a way as some recent months have been much above trend and record breakers so the factors that were causing that may have been short-term but in any event did not show up this November.  I will compare this to the world trend in a future article.

Now I will present the information provided by John Bateman with one additional graphic also from NCEI plus the state ranking maps.

Looking back at October for the United States November 11, 2023 – A Fairly Normal Month Except for the Mississippi River

Most of the information in this report comes from the monthly email I receive from John Bateman. He does public outreach for NOAA and in particular NCEI. I could find the same information and more on the NCEI website but John produces a good summary so I use it or most of it. I also sometimes add additional information from NCEI or other NOAA websites. John Bateman sends me two emails. One on the World situation and one for the U.S.

This article is about October 2023 in the U.S.

One of the things I like to add to what John Bateman sends me is the state ranking maps. These maps show how temperature and precipitation for each state rank relative to the 129 years of what is considered to be the most reliable data we have.

 

This is the U.S.  October temperature trend.  This past October was by no means a record but it was above the trend line. It was a relief in a way as recent months have been much above trend and record breakers so the factors that were causing that may have been short-term but in any event did not show up this October.  I am unable to compare this to the world trend as it is not yet available but will be soon.

Now I will present the information provided by John Bateman with perhaps one additional graphic also from NCEI.

Looking Back at the Global Climate in July 2013 – This past July seems to have been the warmest July on record.

Please note the title was meant to be Looking Back at the Global Climate in July 2023, not July 2013.

Every month, John Bateman sends me a nice email. Actually, he sends me two: one about the U.S. and one about the world.  I have already published an article based on his U.S.-focused email and you can find it HERE. Two days ago he sent me the email for the world. Since they are emails, I usually can not provide a link to what he sent me. He is a spokesperson (not sure that is the right description of his job) for NOAA both NCEI and other parts of NOAA.  For this monthly article, all of the information in his email comes from the NOAA National Centers for Environmental Information so the information he includes in his email and much more can be found HERE.

Since he is a very good writer I use a lot but not all of his material and supplement it with some additional material from the NCEI website or other NOAA websites. I have not indicated what I took from his letter and what I added but if someone has questions on that I can explain it.

Obviously the headline this month is that it looks like July has been the warmest July since this data has been collected.

This is the record of July-only land and ocean temperature anomalies and this July appears to have set a new record high. It is just speculation on my part but I think it is the stepwise rise in temperature we get with an El Nino.

 

Looking Back at July 2023 in the U.S. August 9, 2023

As I often do I reproduced John Bateman’s article in its entirety when I provide a review of the prior month.  I really did not have a link for his article but similar information was available at NCEI but John provides a good summary of the information so I tend to use it.

But I also like to add after John Bateman’s article, a few additional graphics namely the state ranking maps. These show how temperature and precipitation for each state ranks relative to the 139 years of what is considered to be the most reliable data we have.
