Forecasting Droughts and Floods in the Panama Canal
Braddock Linsley
The Panama Canal uses water stored in reservoirs to open the locks; droughts can restrict ships’ drafts, while floods can damage infrastructure. Is there a way to predict these events to help manage the canal? Linsley and colleagues studied the chemical composition of corals in Pacific Ocean waters near the isthmus, producing monthly measurements of river flow into the ocean from 1719 to 2018. They show that the way in which distant volcanic eruptions appear to coincide with El Niño events should help scientists predict fluctuations in rainfall in the region.

extreme weather, dark tweets
Kelton MinorData Science Institute

Minor analyzed daily global weather and 7.7 billion tweets from 190 countries between 2015 and 2021. He found that users’ exposure to extreme rainfall or heat was consistently associated with more negative emotions than days with normal weather. This trend may be accelerating; 2021’s deadly western North American heatwave and western European floods have both generated far more negative sentiment than previous extreme events. With more extreme events, the overall mood in the world is likely to deteriorate further, Minor said.

Alcohol, drugs, and high temperatures
Robbie ParksMailman School of Public Health
Parks and his colleagues examined whether periods of above-average temperatures affect hospitalization for substance abuse. From 1995 to 2014, they found that extreme heat in New York State did drive daily increases in alcohol-related hospital admissions, with the highest correlations outside New York City. Surprisingly, for marijuana, cocaine, opioids, and sedatives, the results were just the opposite: Lower-than-average temperatures were associated with more extreme use.

Co-evolution of man and water
upmanularColumbia Water Center
In this wide-ranging invited talk, Lall will explore how a wise man Evolution related to Earth’s water, and how we and water will co-evolve over the next 100 to 1,000 years or more. Water from glaciers, rivers, lakes, the atmosphere, and ocean currents distributes energy, microbes, and man-made chemicals to all parts of the planet—but our understanding of it is often only relevant to our own immediate needs. Will humans continue to shape the planet to their will, or will nature come back into play? In both cases, what role will water play?

Can crumbling boulders measure earthquake risk?
Charles McBride, william menkeStabilizer

Earthquakes are a threat to the New York City area, but there have been no truly significant earthquakes in history, and no one knows the maximum magnitude of an ancient event. Near the city, researchers are studying boulders that fell from glaciers 15,000 years ago and are in a precarious position where an earthquake could tip them over. 3D models of the boulders allowed them to calculate the force needed to move them out of the way, ruling out earthquakes of those sizes or larger. McBride presents preliminary results.

Tropical Dendrochronology: Beyond Tree Rings
Arturo Pacheco-Solana,
linear oscillator
Dendrochronologists collect year-by-year climate records for many regions going back hundreds or thousands of years, but the tropics remain largely a black hole because trees there don’t form growth rings. Lamont-Doherty scientists have been working to overcome these limitations. Pacheco-Solana discussed work being done in the Bolivian Andes, where new techniques are being used to analyze samples from various remote locations, including cellular structure and anatomy with radiocarbon isotopes.

Pakistan Floods in 2022 and North American Heatwaves in 2021: Common Drivers?
Mingfang TingStabilizer
Ting’s team has been studying the link between extreme weather and large-scale atmospheric currents and the long-term effects of rising temperatures. In this invited talk, she will discuss the forces behind the 2021 heat wave that will see temperatures in the tens of degrees across the western United States and Canada, and the forces behind the unprecedented floods that will hit Pakistan in 2022. She believes this extreme weather may be caused by interconnected factors affecting remote areas.

Where do Ukrainian refugees go?
michael pumaCenter for Climate System Research

Humanitarian agencies and governments face the daunting task of predicting where resources should be allocated to refugees, and nowhere is this more illustrated than Russia’s war on Ukraine. Puma and colleagues modeled the recent movement and route of millions of Ukrainians to surrounding countries. The model shows promise for predicting regional and local-scale movements that can be applied to other crises.

Greenland rises from the ocean
Maggie ThulinStabilizer
Sea levels are rising in much of the world, partly due to the melting of the Greenland ice sheet. But in Greenland itself, sea levels are falling as land previously held down by ice is slowly rebounding upward. This could quickly become a serious problem for coastal communities, whose only mode of travel is through the increasingly shallow adjacent waters. Turrin and his colleagues are working directly with residents to map the seafloor landscape in detail, predict how it will change, and design adaptations. Tinto describes the process, and the progress so far.

Boreal forests approaching thermal tipping point
mukundapala raoStabilizer
The far north is warming so rapidly that summer temperatures in Siberia topped 100 degrees Fahrenheit recently. Experiments by Rao and colleagues show that a few degrees warmer and the Siberian larch, a cornerstone of northern Russian ecosystems, may no longer be able to photosynthesize. Rao warns that this could happen within the next 20 to 30 years, with knock-on effects on the environment and the carbon cycle in this vast region.

In a warmer world, simultaneous crop failures are more likely
Kay CohenhuberStabilizer
Kornhuber and colleagues recently identified a systematic meandering pattern in the northern hemisphere jet stream that has simultaneously triggered crop-damaging heat waves in multiple parts of the world. Climate change could amplify these waves and make them more frequent in major breadbaskets. Now, in new work, they argue that while climate models accurately reproduce this atmospheric pattern, they underestimate the associated surface anomalies and thus the potential future damage to crops.

Resetting the clock for the world’s first nuclear explosion
paul richardsStabilizer

Nuclear test seismic detection pioneer Richards looks back on July 16, 1945, the world’s first atomic bombing, Trinity, in New Mexico. The explosion was initially estimated to have occurred at 5:29 a.m., but that was plus or minus 15 seconds due to a malfunction in the radio timing device. By reanalyzing old-fashioned seismograms of the event (literally, wiggles on paper) using modern digital methods, Richards and colleagues have pinpointed the time to within a few tenths of a second.

U.S. Water Tables in 100 Years
Kerry Lee CallahanStabilizer
The future groundwater level in the U.S. will be shaped by a number of uncertainties, including human use; how precipitation patterns will change; sea level rise; and terrain as the land itself slowly rises or sinks due to the equilibrium rebound at the end of the last ice age Variety. Depending on the location, the water table may rise or fall correspondingly, causing water shortages or excesses. Callaghan presents a range of scenarios for different regions to 2100.

The Future of the U.S. Southwest’s Drought
Richard SeagerStabilizer
Seager and colleagues predicted drought in the western United States long ago and have been at the forefront of research. In their latest study, they say that no matter what happens, the region is unlikely to return to the relatively wetter decades of the 20th century for the foreseeable future due to long-term warming of the climate and the operation of sea surface temperature cycle patterns in the Atlantic Ocean. and the Pacific Ocean. Best-case scenario, they say: ocean circulation increases precipitation a bit, but never returns to its original level; worst-case scenario, changing ocean patterns will leave the region in the next few decades Inside is drier than it is now.

Higher carbon dioxide may affect plant allergies
Lewis ZiskaMailman School of Public Health
It has been suggested that warming temperatures may increase human vulnerability to plant allergies as growing seasons lengthen and the range of allergenic plants expands. But rising levels of carbon dioxide in the atmosphere can itself affect how much plants grow, because it alters plant physiology, for better or worse. In this invited talk, Ziska examines how more carbon dioxide might affect plants and the array of diseases they produce, including contact dermatitis (think poison ivy), reactions to airborne pollen and food allergies.
