scientists know that extreme heat has a negative impact on the human body causing distress in the respiratory and cardiovascular systems and they know that extreme air pollution can also have serious impacts on the human body but as climate change impacts continue globally how often will humans be threatened by both of those extremes when they occur simultaneously a texas a&m university professor has led a regional research study recently published in the brand new journal agu advances answering that question for south asia south asia is a hot-spot for future climate change impacts said dr yangyang xu an assistant professor in the department of atmospheric sciences in the college of geosciences at texas a&m extreme heat occurrences worldwide have increased in recent decades and at the same time many cities are facing severe air pollution problems featuring episodes of high particulate matter (pm) pollution he said this study provides an integrated assessment of human exposure to rare days of both extreme heat and high pm levels our assessment projects that occurrences of heat extremes will increase in frequency by 75% by 2050 that is an increase from 45 days a year to 78 days in a year more concerning is the rare joint events of both extreme heat and extreme pm will increase in frequency by 175% by 2050 xu said climate change is not just a global average number it is something you can feel in your neighborhood he said and thats why regional-scale climate studies are important the studys regional focus was south asia: afghanistan bangladesh bhutan india myanmar nepal and pakistan the scientists used a high-resolution decadal-long model simulation using a state-of-the-science regional chemistry-climate model xu lead the first of its kind research project and scientists from the national center for atmospheric research (ncar) in boulder colorado led the development of the fully coupled chemistry-climate model and performed model simulations for the present-day and future conditions these models allow chemistry and climate to affect each other at every time step said dr rajesh kumar a project scientist at ncar and co-author on the study the study was also co-authored by dr mary barth and dr gerald a meehl both senior scientists at ncar with most of the analysis done by texas a&m atmospheric sciences graduate student xiaokang wu

as climate change impacts continue to become reality it is important for scientists to consider human impacts of multiple extreme conditions happening simultaneously xu said projected increases in humidity and temperature are expected to cause extreme heat stress for the people of south asia where the population is projected to increase from 15 billion people to 2 billion by 2050 it is important to extend this analysis on the co-variability of heat and haze extremes in other regions of the world such as the industrial regions of the us europe and east asia barth said the analysis also showed that the fraction of land exposed to prolonged dual-extreme days increases by more than tenfold in 2050 much larger than the increase when assessed individually i think this study raises a lot of important concerns and much more research is needed over other parts of the world on these compounded extremes the risks they pose and their potential human health effects xu said read the full research study in agu advances ncar is sponsored by the national science foundation and managed by the university corporation for atmospheric research by leslie lee '09

john sarao a phd student in the department of geology and geophysics at texas a&m university completed two scientific cruises with the international ocean discovery program (iodp) in the 2019 fall semester he served as a nannofossil biostratigrapher on both cruises saraos research centers around paleoclimate reconstructions of the past 300 thousand years using microfossils as proxies reconstructions based on calcareous nannofossil-derived alkenones have become one of the more reliable and trusted proxies in paleoclimate research focusing on sediments eocene age or younger he focuses on using changes in nannofossil assemblages as well as the biomarkers produced by the microfossil group to reconstruct the climate history of the eastern margin of the pacific ocean from the holocene his first cruise expedition 379t: extending high resolution paleoclimate records from the chilean margin to the eemian was the inaugural joides resolution (jr) jr100 cruise the jr100 is a month-long non-iodp cruise funded by a new nsf program that enables scientists to use the joides resolution research vessel to collect long sediment cores up to 100 meters in length expedition 379t sailed from jul to aug 2019 leaving port from punta arenas chile and sailed through the straits of magellan to reach the first study site as part of the study 8 sites were drilled along the chilean margin and finally the cruise docked in antofagasta chile this cruise was led by dr samantha bova and dr yair rosenthal from rutgers university

the atmosphere on the joides resolution is a unique one sarao said you take 20 to 30 subject matter experts and allow them to interact in close quarters discussing the science that makes them excited to get up in the morning that facilitates learning and collaboration better than anything ive ever seen it was truly an honor to be part of these two expeditions and be among the select few that get to participate in such a fast-paced world-class experience the second cruise expedition 385: guaymas basin tectonics and biosphere was an official iodp cruise focused on the tectonic history and biosphere of guaymas basin gulf of california expedition 385 sailed out of san diego ca from september to november 2019 the co-chief scientists in charge of the cruise were dr andreas teske of the university of north carolina and dr daniel lizarralde of the woods hole oceanographic institution iodp is funded by the national science foundation and other participating countries iodp coordinates seagoing expeditions to study the history of the earth recorded in sediments and rocks beneath the ocean floor the joides resolution science operator (jrso) operates the scientific drillship and the jrso is based in the texas a&m college of geosciences one of the three iodp ocean sediment core repositories is housed at texas a&m by ali snell
