The Counting of Nine Billion Trees Could Help Manage Climate Credits and Nature Restoration - Science Daily - Global Warming (Mar 23, 2023) |
|
Mar 23, 2023 · The purchase of indulgences for CO2 emissions is gaining steam among global corporations. Carbon offset credits allow companies to emit a given amount of CO2 in exchange for the greenhouse gas being neutralized elsewhere, in the form of trees planted or left unfelled.
But with billions upon billions of trees across the planet, keeping track of how many are added and how many are disappearing is tough, to say the least. Now, researchers from the University of Copenhagen's Department of Geosciences and Natural Resource Management and Department of Computer Science, in collaboration with the American space agency NASA, have pioneered a method that makes it possible to count the ...

Improved Management of Farmed Peatlands Could Cut 500 Million Tons CO2 - Science Daily - Global Warming (May 27, 2021) |
|
May 27, 2021 · Substantial cuts in global greenhouse gas emissions could be achieved by raising water levels in agricultural peatlands, according to a new study in the journal Nature.
Peatlands occupy just three per cent of the world's land surface area but store a similar amount of carbon to all terrestrial vegetation, as well as supporting unique biodiversity.
In their natural state, they can mitigate climate change by continuously removing CO2 from the atmosphere and storing it securely under waterlogged conditions for thousands of years.
But many peatland areas have been substantially modified by human activity, including drainage for agriculture and forest plantations. This ... Read more ...

New Tool for Reconstructing Ancient Sea Ice to Study Climate Change - Science Daily - Global Warming (Jan 19, 2021) |
|
Jan 19, 2021 · Sea ice is a critical indicator of changes in the Earth's climate. A new discovery by Brown University researchers could provide scientists a new way to reconstruct sea ice abundance and distribution information from the ancient past, which could aid in understanding human-induced climate change happening now.
In a study published in Nature Communications, the researchers show that an organic molecule often found in high-latitude ocean sediments, known as tetra-unsaturated alkenone (C37:4), is produced by one or more previously unknown species of ice-dwelling algae. As sea ice concentration ebbs and flows, so do the algae associated with it, as well as the molecules they leave ... Read more ...

Uncovering How Grasslands Changed Our Climate - Science Daily - Global Warming (Jan 19, 2021) |
|
Jan 19, 2021 · Grasslands are managed worldwide to support livestock production, while remaining natural or semi-natural ones provide critical services that contribute to the wellbeing of both people and the planet. Human activities are however causing grasslands to become a source of greenhouse gas emissions rather than a carbon sink. A new study uncovered how grasslands used by humans have changed our climate over the last centuries.
Grasslands are the most extensive terrestrial biome on Earth and are critically important for animal forage, biodiversity, and ecosystem services. They absorb and release carbon dioxide (CO2), and emit methane (CH4) from grazing livestock and nitrous oxide ... Read more ...

A Groggy Climate Giant: Subsea Permafrost Is Still Waking Up After 12,000 Years - Science Daily - Global Warming (Dec 20, 2020) |
|
Dec 20, 2020 · In the far north, the swelling Arctic Ocean inundated vast swaths of coastal tundra and steppe ecosystems. Though the ocean water was only a few degrees above freezing, it started to thaw the permafrost beneath it, exposing billions of tons of organic matter to microbial breakdown. The decomposing organic matter began producing CO2 and CH4, two of the most important greenhouse gases.
Sayedi and an international team of 25 permafrost researchers worked under the coordination of the Permafrost Carbon Network (PCN), which is supported by the U.S. National Science Foundation. The researchers combined findings from published and unpublished studies to estimate the size of the past ... Read more ...

Applying Compost to Landfills Could Have Environmental Benefits - Science Daily - Global Warming (Dec 20, 2020) |
|
Dec 20, 2020 · Many people think of composting organic matter as a way of keeping solid waste out of landfills, but a new study from North Carolina State University finds there can be significant environmental benefits associated with using compost at landfills.
"There are an increasing number of composting programs out there, and many of them are required to use the resulting compost 'beneficially,'" says James Levis, corresponding author of the study and a research assistant professor of civil, construction and environmental engineering at NC State. "A lot of state and local regulations don't recognize 'alternative daily cover' as a beneficial use. But our work shows that using compost as ... Read more ...

Babbler Bird Falls Into Climate Change Trap - Science Daily - Global Warming (Dec 20, 2020) |
|
Dec 20, 2020 · Animals can fall into an "ecological trap" by altering their behaviour in the "wrong direction" in response to climate change, researchers say.
The so-called "rescue hypothesis" suggests many species might successfully adapt to changing conditions, especially those that are flexible in their behaviour.
But a new study, by the University of Exeter, found that chestnut-crowned babbler birds responded to rising temperatures by changing their behaviour in ways that could actually reduce successful breeding.
This occurred because they reacted to warm peak temperatures in early spring by breeding earlier -- but average temperatures at this time are still colder than ... Read more ...

Bacteria in Iron-Deficient Environments Process Carbon Sources Selectively - Science Daily - Global Warming (Dec 20, 2020) |
|
Dec 20, 2020 · When humans have low iron levels, they tend to feel weak, fatigued and dizzy. This fatigue prevents patients with iron-deficient anemia from exercising or exerting themselves in order to conserve energy.
Similarly, in low-iron environments, microbes survive by slowing down carbon processing and extracting iron from minerals. However, this strategy requires microbes to invest precious food sources into producing mineral-dissolving compounds. Given this paradox, researchers wanted to understand how microbes sustain survival strategies in environments with too little iron to thrive.
Iron is critical to carbon metabolism because it's required by the proteins involved in ... Read more ...

Can Water Saving Traits Help Wine Survive Climate Change? - Science Daily - Global Warming (Dec 20, 2020) |
|
Dec 20, 2020 · Climate change is expected to make many grape-growing regions too hot and dry to produce high-quality wine from traditional varieties. But scientists at the University of California, Davis, have found that wine grape varieties from regions that are more prone to stress have traits that could help them cope with climate change.
The study, published in the Journal of Experimental Botany, finds that varieties that produce their best wines in warmer, drier regions have traits that conserve water, helping the vines extend their water resources to last over the growing season.
"The relationships between grape varieties and regions have historically been based on wine, without ... Read more ...

Central Europe: Dry Aprils Pave the Way for Summer Droughts - Science Daily - Global Warming (Dec 20, 2020) |
|
Dec 20, 2020 · In the past 20 years, Central Europe has experienced six summer heat waves and droughts. Until now, however, it was unclear what factors led to these extreme events. Researchers from two Helmholtz Centres (AWI & UFZ) have now discovered that in Central Europe, temperature and precipitation patterns in April play a vital role in determining whether or not the soils are drier than average in the following summer. If the April is too warm, with little precipitation, a large proportion of the moisture stored in the soil evaporates, making a summer drought more likely. The team has also identified one of the reasons for the repeated dry Aprils and the correspondingly increased risk of ... Read more ...

Change in Global Precipitation Patterns as a Result of Climate Change - Science Daily - Global Warming (Dec 20, 2020) |
|
Dec 20, 2020 · The Earth's climate system is largely determined by the differences in temperature between the tropics and the poles. Global warming is likely to cause global atmospheric circulation to change and progressively revert to a situation similar to that of 5,000 to 10,000 years ago. This is the conclusion of a study undertaken by a research team led by Dr. Michael Deininger, the results of which have been published in Nature Communications.
At the Institute of Geosciences at Johannes Gutenberg University Mainz (JGU), Deininger investigated how regional climate systems have changed since the beginning of the current interglacial period some 10,000 years ago and what conclusions can ... Read more ...

Climate Change Warms Groundwater in Bavaria - Science Daily - Global Warming (Dec 20, 2020) |
|
Dec 20, 2020 · Groundwater reservoirs in Bavaria have warmed considerably over the past few decades. A new study by researchers at Martin Luther University Halle-Wittenberg (MLU) compares temperatures at 35 measuring stations, taken at different depths, with data from the 1990s. Water found at a depth of 20 metres was almost one degree warmer on average than 30 years ago. The findings were published in the journal "Frontiers in Earth Science."
As the air warms, the ground also becomes warmer over time -- ultimately resulting in warmer groundwater. Geologists call this thermal coupling. "Unlike the atmosphere, however, the earth's sub-surface is very sluggish," explains Professor Peter Bayer, ... Read more ...

Critical Temperature for Tropical Tree Lifespan Revealed - Science Daily - Global Warming (Dec 20, 2020) |
|
Dec 20, 2020 · For the first time scientists have provided clear evidence that tropical tree lifespan decreases above a critical temperature threshold.
Findings, published today (14 December) in the journal PNAS (Proceedings of the National Academy of Sciences) show that across the tropics, tree lifespans decrease for temperatures above 25 C.
As temperatures are rising rapidly across large parts of the tropics, tree mortality is likely to accelerate in substantial parts of the tropics, including the Amazon, Pantanal and Atlantic forests with implications for animal habitats, air quality and carbon stocks.
Although tropical rainforests account for only 7% of all land, they are ... Read more ...

Greenland 'knickpoints' Could Stall Spread of Glacial Thinning - Science Daily - Global Warming (Dec 20, 2020) |
|
Dec 20, 2020 · The jagged terrain of Greenland's mountains is protecting some of the island's outlet glaciers from warm coastal waters, according to a team of researchers that included scientists from The University of Texas at Austin and NASA.
Outlet glaciers protrude from the ice sheet into the sea, where surging ocean heat can speed up the loss of ice, making the glaciers thinner and raising sea levels. The scientists found that steep slopes in the bedrock under the ice form stabilizing areas the researchers termed "knickpoints" that prevent coastal thinning from reaching further inland.
The findings were published Dec. 11 in the journal Geophysical Research Letters.

How Climate Change Is Disrupting Ecosystems - Science Daily - Global Warming (Dec 20, 2020) |
|
Dec 20, 2020 · The world is getting warmer and warmer -- and many organisms native to lower latitudes or elevations are moving higher.
However, novel organisms moving into a new habitat could disturb the ecological balance which has been established over a long period. Plants and herbivores are characterised by long-term co-evolution, shaping both their geographic distribution and the characteristics that they display in their occupied sites.
At higher elevations, this is seen in insect herbivores being generally less abundant and plants in turn being less well defended against herbivores, as a result of lower energy and shorter growing seasons. In contrast, low-elevation plant species ... Read more ...
