Published on Leave a comment on The Two Hottest Days On Earth Were This Week

Uh-oh. The Earth is really warming up, and very rapidly. Sunday was the hottest day recorded globally. But then... Monday was even hotter! This means that in the space of several days, two global records were set in two days.

And it will continue to get warmer (hotter) in the coming months and years. We do know what is causing this climate change of increased global warmth - it's the burning of fossil fuels (e.g., gas, oil, coal). The big question - can humans change their ways?

From The New York Times, the Climate Newsletter: Earth’s Hottest Days Ever

Twice this week, global temperatures broke records, but scientists are more concerned about a longer-term pattern of hotter weather.

This past Sunday was the warmest single day ever recorded, according to the Copernicus Climate Change Service, the European Union-funded research organization. That is, until Monday, when global temperatures inched up a bit more. Then Monday became the hottest day in modern history, with an average global temperature of 17.16 Celsius or 62.88 Fahrenheit. Tuesday was almost as hot. ...continue reading "The Two Hottest Days On Earth Were This Week"

Published on Leave a comment on Carbon Dioxide Levels In Atmosphere Keep Rapidly Rising

It shouldn't be a surprise to read that carbon dioxide levels in the atmosphere are surging and accumulating faster than ever. In May, it surged to 427 parts per million (426.90 ppm) - while in 1960 it was about 320 ppm.  It's depressing, and it doesn't bode well for our future.

These high levels of carbon dioxide are a major driver of the record-setting heat we've been experiencing in recent years. Carbon dioxide is the gas that accounts for the majority of global warming (yes, climate change) and is caused by human activities. The human activities are burning of fossil fuels, such as gas and oil - in vehicles, coal-fired plants, large industrial operations, ships, airplanes, rockets.

Excerpts from NOAA (National Oceanic and Atmospheric Administration): During a year of extremes, carbon dioxide levels surge faster than ever

Carbon dioxide is accumulating in the atmosphere faster than ever — accelerating on a steep rise to levels far above any experienced during human existence, scientists from NOAA and the Scripps Institution of Oceanography at the University of California San Diego announced today. ...continue reading "Carbon Dioxide Levels In Atmosphere Keep Rapidly Rising"

Published on Leave a comment on Climate Scientists Are Very Worried About Our Future

The world is heating up quickly and climate scientists are very worried and scared about what's in our future. A recent survey conducted by The Guardian finds that climate scientists are very pessimistic about our ability to limit future temperature increases.

By the way, this past April was the 11th straight month of global record-breaking heat, and it looks like this trend will continue. Most of the scientists surveyed felt that we will blow past the internationally agreed 2.7 degrees F and will hit at least a 4.5 degrees F increase in this century. Almost half thought there would be a 5.4 degrees F increase.

This uncontrolled temperature increase will result in catastrophic changes for the world. Famines, mass migrations, heatwaves, wildfires, extreme storms! It's on us, especially our governments, to take action. Now!

Excerpts from The Guardian: World’s top climate scientists expect global heating to blast past 1.5C target

Hundreds of the world’s leading climate scientists expect global temperatures to rise to at least 2.5C (4.5F) above preindustrial levels this century, blasting past internationally agreed targets and causing catastrophic consequences for humanity and the planet, an exclusive Guardian survey has revealed. ...continue reading "Climate Scientists Are Very Worried About Our Future"

Published on Leave a comment on Welcome To Global Weirding

There's a new word that describes all the weird weather we've been having recently. It's global weirding. It describes the weird weather extremes that we've been experiencing - for example, the extreme heat in Arizona last summer (more than a month of over 110 degrees F), extreme wildfires (Canada last year), extreme torrential rains.

All sorts of weather records are being broken each year. This weird and extreme weather is occurring because our climate is changing. Thomas Friedman described global weirding years ago. He wrote in the NY Times:

"Avoid the term “global warming.” I prefer the term “global weirding,” because that is what actually happens as global temperatures rise and the climate changes. The weather gets weird. The hots are expected to get hotter, the wets wetter, the dries drier and the most violent storms more numerous."

From Discover: As Weather Extremes Increase in 2023, Global Weirding Becomes a Better Term

While temperatures in Phoenix soared above 110 degrees Fahrenheit for a record-shattering 31 straight days in July, people began turning up in emergency rooms with third-degree burns they’d suffered after falling — their skin seared by blistering hot pavement. Although not unprecedented, burn specialists said the number and severity of injuries were much higher than ever before. ...continue reading "Welcome To Global Weirding"

Published on Leave a comment on Earth Just Had Its Warmest March

Once again, another month had record warmth. March 2024 was the warmest March on Earth. And it's the 10th month in a row that set global heat records  (since June 2023). Yikes!

Ocean warmth has had 11 record-setting months in a row. Meanwhile, scientists are divided over whether climate change (and warmth) is accelerating or all this record warmth month after month is in line with climate change predictions.

The big question: What will summer heat be like?

From The Weather Channel: Earth's Warmest March Is 10th Straight Record Month, Just-Released Data Shows

March was E​arth's warmest on record, according to preliminary data, the latest month in a stretch of heat records since the planet's hottest year in 2023. ...continue reading "Earth Just Had Its Warmest March"

Published on Leave a comment on Hurricanes Are Getting Stronger

It truly is a warming world. Scientists normally label hurricanes according to their strength from Category 1 to Category 5 (wind speeds 158 mph or greater). Some climate scientists are now proposing adding a Category 6 due to the increased strength of recent hurricanes.

The new Category 6 would be storms with wind speeds greater than 192 mph. When the researchers examined wind speeds from past storms, they found 5 storms that would have been reclassified as Category 6. And they all occurred in the past decade.

The researchers expect that as the world warms, the number of Category 6 storms will increase. Stronger storms = more destruction. Yikes!

By the way, hurricanes, tropical storms, and typhoons are essentially the same kind of storm. They are just called different names in different parts of the world.

From Science Daily: In a warming world, climate scientists consider category 6 hurricanes

For more than 50 years, the National Hurricane Center has used the Saffir-Simpson Windscale to communicate the risk of property damage; it labels a hurricane on a scale from Category 1 (wind speeds between 74 -- 95 mph) to Category 5 (wind speeds of 158 mph or greater). ...continue reading "Hurricanes Are Getting Stronger"

Published on Leave a comment on Will 2024 Be Warmer Than 2023?

It became official this month - the year 2023 was the warmest year on record! The global average temperature was significantly warmer than any other year.

Uh-oh. This is climate change, and the temperature increase is fueled by the burning of fossil fuels (e.g., coal, oil, gas) - which releases large amounts of carbon dioxide and other greenhouse gasses into the air.

Scientists think that 2023 is probably the hottest year going back 125,000 years. Will 2024 be another record-breaking year? The baseline is being set higher and higher, yet we keep breaking the new baselines. Important: "The 10 warmest years since 1850 have all occurred in the past decade."

Excerpts from NOAA (National Oceanic and Atmospheric Administration) - [do go to the site and see the graphics]: 2023 was the world’s warmest year on record, by far

It’s official: 2023 was the planet’s warmest year on record, according to an analysis by scientists from NOAA’s National Centers for Environmental Information (NCEI).

Along with the historic heat, Antarctic sea ice coverage dropped to a record low in 2023. ...continue reading "Will 2024 Be Warmer Than 2023?"

Published on Leave a comment on Scientists Report That July Was the Hottest Month On Record

We knew it was hot in July. Record breaking hot. Europe's climate monitoring organization (Copernicus Climate Change Service) announced this week that July was the Earth's hottest month on record. By a wide margin.

The global average temperature for July was 62.51 degrees F (16.95 degrees C). The record for hottest month prior to this was July 2019. According to experts, July was the hottest month in about 120,000 years!

The global sea surface temperatures for July also broke historic records. The sea ice in the Antarctic broke the July record for below average sea ice. Do you see a pattern? Uh - oh. The world is really warming up...

According to a Climate Central report, more than 6.5 billion people  (or more than 81% of people on Earth) experienced hotter temperatures in July  than they would have without human-caused climate change.

Excerpts from World Meteorological Organization: July 2023 is set to be the hottest month on record

According to ERA5 data from the EU-funded Copernicus Climate Change Service (C3S), the first three weeks of July have been the warmest three-week period on record and the month is on track to be the hottest July and the hottest month on record. These temperatures have been related to heatwaves in large parts of North America, Asia and Europe, which along with wildfires in countries including Canada and Greece, have had major impacts on people’s health, the environment and economies. ...continue reading "Scientists Report That July Was the Hottest Month On Record"

Published on Leave a comment on We’re On Track For Each Summer to Be Hotter Than Ever

This past Monday (July 3) the average temperature on Earth was the hottest day ever recorded. But then...Tuesday broke Monday's records for hottest day for Earth. It hit 62.92 degrees Fahrenheit (17.18 degrees Celsius)

Welcome to the new normal. In fact, this summer could be the coolest summer of the rest of your life! Get ready for more and longer heat waves. For summer to start earlier, last longer, and be hotter.

Why is this occurring? Climate change. All the scientific predictions are coming true. And yet the US government, politicians, big business, and all of us are refusing to take real action. We need a huge reduction of fossil fuel emissions and new technologies to pull carbon dioxide out of the air to stop extreme climate changes from occurring.

Several good articles about what is going on: 1) From The Guardian: Tuesday was world’s hottest day on record – breaking Monday’s record

World temperature records have been broken for a second day in a row, data suggests, as experts issued a warning that this year’s warmest days are still to come – and with them the warmest days ever recorded.

2) From the Washington Post: This July 4 was hot. Earth’s hottest day on record, in fact.

... some scientists believe July 4 may have been one of the hottest days on Earth in about 125,000 years, due to a dangerous combination of climate change causing global temperatures to soar, the return of the El Niño pattern and the start of summer in the Northern Hemisphere.  ...continue reading "We’re On Track For Each Summer to Be Hotter Than Ever"

Published on Leave a comment on Carbon Dioxide Levels Are Higher Than Ever In the Atmosphere

Holy moly! Our carbon dioxide levels are rising, really rising! Every year there is a new high, and this year is no exception.

According to NASA, in May at the Mauna Observatory in Hawaii the carbon dioxide measurement was 421 ppm. It's called the "global atmospheric carbon dioxide concentration". This week the reading at Mauna Launa Observatory is 423.96 ppm. It's going up! And yup, this is climate change.

From the NASA Global Climate Change page on Carbon Dioxide (go to the link to see the graphs, and prepare to be shocked).

Carbon Dioxide  LATEST MEASUREMENT:  May 2023     421 ppm

Key Takeaway: Carbon dioxide in the atmosphere warms the planet, causing climate change. Human activities have raised the atmosphere’s carbon dioxide content by 50% in less than 200 years.

Carbon dioxide (CO2) is an important heat-trapping gas, or greenhouse gas, that comes from the extraction and burning of fossil fuels (such as coal, oil, and natural gas), from wildfires, and from natural processes like volcanic eruptions.

Since the beginning of industrial times (in the 18th century), human activities have raised atmospheric CO2 by 50% – meaning the amount of CO2 is now 150% of its value in 1750. This is greater than what naturally happened at the end of the last ice age 20,000 years ago.

The animated map shows how global carbon dioxide has changed over time. Note how the map changes colors as the amount of CO2 rises from 365 parts per million (ppm) in 2002 to over 400 ppm currently. (“Parts per million” refers to the number of carbon dioxide molecules per million molecules of dry air.) These measurements are from the mid-troposphere, the layer of Earth's atmosphere that is 8 to 12 kilometers (about 5 to 7 miles) above the ground.

One big concern that needs to be addressed: What will high carbon dioxide levels do to our thinking processes? Over the years carbon dioxide levels have been rising, and are now at levels not experienced in several million years!

Think of a "stuffy room" where it is harder to think - this can already occur starting at about 600 ppm of CO2, and known to occur at 945 ppm and higher (in rooms with many people in them). While current CO2 levels are below that, we are faced with the possibility that if they keep rising we will get there eventually - and there will be no escape from the "stuffy room" feeling!
