Massive 'Climate Clock' Urging Governments to Act Is Unveiled in New York City

Some advocates kicked off next week's Climate Week NYC early Saturday by repurposing the Metronome, a famous art installation in Union Square that used to display the time of day, as a massive "Climate Clock" in an effort to pressure governments worldwide to take swift, bold action to reduce greenhouse gas emissions and rein in human-caused global heating.
"The clock is a way to speak science to power," project co-founder Andrew Boyd said in a statement. "The clock is telling us we must reduce our emissions as much as we can as fast as we can. The technology is there. We can do this—and in the process, create a healthier, more just world for all of us. Our planet has a deadline. But we can turn it into a lifeline."
Launched as people across the country are facing the deadly, devastating impacts of climate change—from historic wildfires in western states to slow-moving hurricanes and the resulting floods on the Gulf Coast—the clock in New York City on Saturday warned that the international community only has seven years and 102 days to "undertake bold transformation of our energy system and economy" in hopes of keeping global temperature rise under 1.5 degrees Celsius.
"Climate Change is already here. This clock is not an alarm clock saying, in seven years it will ring and we need to wake up! It's more like a stopwatch already running that we have to keep pace with," explained Gan Golan, the project originator. "We need to take action today, tomorrow, and the day after that. Let's get moving. Every second counts. We need to act in time."

A mobile climate clock that Swedish youth activist Greta Thunberg "now carries with her, as well as the larger Climate Clock project, was assembled by a team of artists, makers, scientists, and activists based in New York, and is part of the Beautiful Trouble community of projects," according to Climateclock.world, which details the science behind the numbers displayed and how to install clocks in other cities.

"In an accompanying app, the artists include more detail about solutions," Fast Company reported Saturday. "Another number tracks the current percentage of renewable energy in the world. An interactive tool shows how to 'flatten the climate curve' and how much difference it makes to invest more now, and to move more quickly. A DIY maker kit explains how to make a countdown clock of your own."

On his first day in office President Joe Biden started signing executive orders to reverse Trump administration policies. One sweeping directive calls for stronger action to protect public health and the environment and hold polluters accountable, including those who "disproportionately harm communities of color and low-income communities."
Michael S. Regan, President Biden's nominee to lead the U.S. Environmental Protection Agency, grew up near a coal-burning power plant in North Carolina and has pledged to "enact an environmental justice framework that empowers people in all communities." NCDEQ

Clear-cutting a forest is relatively easy—just pick a tree and start chopping. But there are benefits to more sophisticated forest management. One technique—which involves repeatedly harvesting smaller trees every 30 or so years but leaving an upper story of larger trees for longer periods (60, 90, or 120 years)—ensures a steady supply of both firewood and construction timber.
A Pattern in the Rings<p>The <a href="https://www.encyclopedia.com/science/dictionaries-thesauruses-pictures-and-press-releases/coppice-standards-0" target="_blank">coppice-with-standards</a> management practice produces a two-story forest, said <a href="https://www.researchgate.net/profile/Bernhard_Muigg" target="_blank">Bernhard Muigg</a>, a dendrochronologist at the University of Freiburg in Germany. "You have an upper story of single trees that are allowed to grow for several understory generations."</p><p>That arrangement imprints a characteristic tree ring pattern in a forest's upper story trees (the "standards"): thick rings indicative of heavy growth, which show up at regular intervals as the surrounding smaller trees are cut down. "The trees are growing faster," said Muigg. "You can really see it with your naked eye."</p><p>Muigg and his collaborators characterized that <a href="https://ltrr.arizona.edu/about/treerings" target="_blank">dendrochronological pattern</a> in 161 oak trees growing in central Germany, one of the few remaining sites in Europe with actively managed coppice-with-standards forests. They found up to nine cycles of heavy growth in the trees, the oldest of which was planted in 1761. The researchers then turned to a historical data set — more than 2,000 oak <a href="https://eos.org/articles/podcast-discovering-europes-history-through-its-timbers" target="_blank" rel="noopener noreferrer">timbers from buildings and archaeological sites</a> in Germany and France dating from between 300 and 2015 — to look for a similar pattern.</p>
A Gap of 500 Years<p>The team found wood with the characteristic coppice-with-standards tree ring pattern dating to as early as the 6th century. That was a surprise, Muigg and his colleagues concluded, because the first mention of this forest management practice in historical documents occurred only roughly 500 years later, in the 13th century.</p><p>It's probable that forest management practices were not well documented prior to the High Middle Ages (1000–1250), the researchers suggested. "Forests are mainly mentioned in the context of royal hunting interests or donations," said Muigg. Dendrochronological studies are particularly important because they can reveal information not captured by a sparse historical record, he added.</p><p>These results were <a href="https://www.nature.com/articles/s41598-020-78933-8" target="_blank">published in December in <em>Scientific Reports</em></a>.</p><p>"It's nice to see the longevity and the history of coppice-with-standards," said <a href="https://www.teagasc.ie/contact/staff-directory/s/ian-short/" target="_blank">Ian Short</a>, a forestry researcher at Teagasc, the Agriculture and Food Development Authority in Ireland, not involved in the research. This technique is valuable because it promotes conservation and habitat biodiversity, Short said. "In the next 10 or 20 years, I think we'll see more coppice-with-standards coming back into production."</p><p>In the future, Muigg and his collaborators hope to analyze a larger sample of historic timbers to trace how the coppice-with-standards practice spread throughout Europe. It will be interesting to understand where this technique originated and how it propagated, said Muigg, and there are plenty of old pieces of wood waiting to be analyzed. "There [are] tons of dendrochronological data."</p><p><em><a href="mailto:email@example.com" target="_blank" rel="noopener noreferrer">Katherine Kornei</a> is a freelance science journalist covering Earth and space science.

Earth's ice is melting 57 percent faster than in the 1990s and the world has lost more than 28 trillion tons of ice since 1994, research published Monday in The Cryosphere shows.
