"A century of gradual reforestation across the American East and Southeast has kept the region cooler than it otherwise would have become, a new study shows.

The pioneering study of progress shows how the last 25 years of accelerated reforestation around the world might significantly pay off in the second half of the 21st century.

Using a variety of calculative methods and estimations based on satellite and temperature data from weather stations, the authors determined that forests in the eastern United States cool the land surface by 1.8 – 3.6°F annually compared to nearby grasslands and croplands, with the strongest effect seen in summer, when cooling amounts to 3.6 – 9°F.

The younger the forest, the more this cooling effect was detected, with forest trees between 20 and 40 years old offering the coolest temperatures underneath.

“The reforestation has been remarkable and we have shown this has translated into the surrounding air temperature,” Mallory Barnes, an environmental scientist at Indiana University who led the research, told The Guardian.

“Moving forward, we need to think about tree planting not just as a way to absorb carbon dioxide but also the cooling effects in adapting for climate change, to help cities be resilient against these very hot temperatures.”

The cooling of the land surface affected the air near ground level as well, with a stepwise reduction in heat linked to reductions in near-surface air temps.

“Analyses of historical land cover and air temperature trends showed that the cooling benefits of reforestation extend across the landscape,” the authors write. “Locations surrounded by reforestation were up to 1.8°F cooler than neighboring locations that did not undergo land cover change, and areas dominated by regrowing forests were associated with cooling temperature trends in much of the Eastern United States.”

By the 1930s, forest cover loss in the eastern states like the Carolinas and Mississippi had stopped, as the descendants of European settlers moved in greater and greater numbers into cities and marginal agricultural land was abandoned.

The Civilian Conservation Corps undertook large replanting efforts of forests that had been cleared, and this is believed to be what is causing the lower average temperatures observed in the study data.

However, the authors note that other causes, like more sophisticated crop irrigation and increases in airborne pollutants that block incoming sunlight, may have also contributed to the lowering of temperatures over time. They also note that tree planting might not always produce this effect, such as in the boreal zone where increases in trees are linked with increases in humidity that way raise average temperatures."

Researchers have confirmed that 2023 was the hottest year on record. The European Union's Copernicus climate change service looked at global temperature records going back to 1850. And scientists warn this year could be even hotter.

New Record

On Monday and Tuesday, the Earth experienced the hottest Global Temperature recorded.

How much hotter must it get for something to be done? How many ecosystems must be damaged? How many people have to suffer? How much more?

Are fossil fuels really worth all this damage? Is it so inconvenient to change our ways that we are willing to let the world burn? Is it really worth it?

What will it take for there to be change?

Climate

Climate is still controversial?  Yes. I’m reminded every time I post a climate story and a denier pops up.  

Why do I care about climate?  Climate impacts everything.  Food chain, jobs, housing, health, animals, plants, etc.   I’m saving info so I can find it again.  To learn - about trends, land use, natural patterns, and habitats.  (I try to be aware of science funded by corporate interests.  See Toxic Sludge Is Good For You)   

“When Did Climate Science Begin?”

How 19th Century Scientists Predicted Global Warming | Jstor.org

1824 & 1837 Papers by Joseph Fourier, a French mathematician and physicist who spent his career pondering the mechanics and equations governing heat transfer.

1856 Eunice Newton Foote experimented with heat trapping gases (CO2) and wrote a paper for The American Journal of Science.   Interesting factoid: “When time came to present her research before the American Association for the Advancement of Science—among the country’s most eminent scientific gatherings—they didn’t allow women to speak, so it was read by a male colleague.”

“Nature changes all the time!  Why worry?”  

What’s the Difference Between Weather and Climate?  |  NASA

The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time. Climate is how the atmosphere "behaves" over relatively long periods of time.

In addition to long-term climate change, there are shorter term climate variations. This so-called climate variability can be represented by periodic or intermittent changes related to El Niño, La Niña, volcanic eruptions, or other changes in the Earth system.

United States Global Change Research Program (USGCRP) 

“Thousands of studies conducted by researchers around the world have documented increases in temperature at Earth’s surface, as well as in the atmosphere and oceans. Many other aspects of global climate are changing as well. Human activities, especially emissions of heat-trapping greenhouse gases from fossil fuel combustion, deforestation, and land-use change, are the primary driver of the climate changes observed in the industrial era.”

Climate science is not new.  Is not a fad.   The climate scientists are talking - Will we listen?

From USAFacts/New York Times:

2021 was the sixth-warmest year on record.

All states, and especially in the Northeast and upper Midwest, were warmer in 2021 than the 20th century average.

Average US rainfall for the last decade is 3.6% higher than the average rainfall for the previous decade.

In 2021, Mississippi and Massachusetts each had more than 10 inches of precipitation over their 20th century averages.

Confirmed: Summer 2023 Hottest in NASA’s Record

All three months of summer 2023 broke records. July 2023 was the hottest month ever recorded, and the hottest July. June 2023 was the hottest June, and August 2023 was the hottest August.

NASA’s temperature record, GISTEMP, starts in 1880, when consistent, modern recordkeeping became possible. Our record uses millions of measurements of surface temperature from weather stations, ships and ocean buoys, and Antarctic research stations. Other agencies and organizations who keep similar global temperature records find the same pattern of long-term warming.

Global temperatures are rising from increased emissions of greenhouse gasses, like carbon dioxide and methane. Over the last 200 years, humans have raised atmospheric CO2 by nearly 50%, primarily through the burning of fossil fuels.

Drivers of climate change, both natural and human-caused, leave distinct fingerprints. Through observations and modeling, NASA researchers confirm that the current warming is the result of human activities, particularly increased greenhouse gas emissions.

Chris Hedges: The Dawn of the Apocalypse

We were warned for decades about the death march we are on because of global warming. And yet, the global ruling class continues to frog-march us towards extinction. By Chris Hedges/ ScheerPost/ July 26, 2022 The past week has seen record-breaking heat waves across Europe. Wildfires have ripped through Spain, Portugal and France. London’s fire brigade experienced its busiest day since World War…

Highlighting the critical role that nature plays in both adaption and mitigation simultaneously.

For the first time, world leaders have clearly recognised the interlinked relationship between the global biodiversity and climate crises and the critical role that nature plays in both adaption and mitigation simultaneously. This is an important and welcome move forward.

However, to keep global temperature rise within 1.5°C, we need to move from recognition to establishing concrete pathways for delivery. In this respect, while the COP decisions are an important step forward, the absence of a clear reference to Nature-based Solutions (NbS) is a missed opportunity that will need to be revisited as soon as possible.

Nature-based Solutions provide a widely accepted operational framework for harnessing nature’s role in addressing climate change. A clear reference to Nature-based Solutions in UNFCCC decisions would give confidence to the many state and non-state actors who are already applying them at scale, and provide improved accountability and oversight of NbS by Parties.

The global average temperature on Friday was more than two degrees Celsius hotter than pre-industrial levels for the first time on record, Europe's Copernicus climate monitor said Monday, adding Saturday likely continued the unprecedented warming streak. ​Months of extraordinary heat are expected to make 2023 the hottest year in history, with droughts, massive wildfires and fierce storms ravaging swathes of the planet. ​According to new data, global temperatures on November 17 were 2.07 °C above the pre-industrial average, the EU's Climate Change Service (C3S). "This was the first day when global temperature was more than 2 °C above 1850-1900 levels," said Samantha Burgess, C3S Deputy Head on X, formerly known as Twitter. Preliminary data suggests the record continued into Saturday, with temperatures around 2.06 °C above the pre-industrial average, Copernicus said on X.
