Gen Z just saw the worst war in Israel in 50 years break out all over the internet, but they were raised on 'disturbing images' 6 insurrection—an event unseen for centuries in American politics. Then there’s the first major European ground war since World War II in Ukraine, not to mention market crashes in 2008 and 2020 that recall the Great Depression itself. As the first digitally native generation, Gen Z is experiencing it all through videos, images, and articles online, which is shaping their mental health, workplace attitudes, and financial habits in visible ways. It’s no wonder, this Gen Z reporter notes, that 46% of young workers ages 18 to 26 say that they are regularly so distraught over what is happening in the news that they are unable to function at work, according to a 2023 Edelman report. By comparison, 38% of millennials, 24% of Gen Xers, and 19% of baby boomers and older generations say the same. Everything about their behavior communicates that Gen Z is just not okay with it. This ranges from their widespread, hell-bent determination to find purpose in work and pushing their employers to have a social conscience, to a sense of despair over their own and the world’s future finances.

They have largely given up on saving money and instead dish out for little “treats” as a way to cope with the larger absurdity of 21st-century life.

Consider the lifetime that was three years ago, as Gen Z emerged into young adulthood, when online videos of the murder of George Floyd shook the country in May 2020, resulting in a summer of violent Black Lives Matter protests and riots.

Gen Z just saw the worst war in Israel in 50 years break out all over the internet, but they were raised on 'disturbing images' Roughly 60% of Gen Zers say they are stressed about money this year more than last year, according to a Bankrate survey from July. It’s no surprise either—85% of Gen Zers say that they couldn’t afford one month’s expenses if they lost their job today.

One Fidelity survey backs this argument: 45% of 18- to 35-year-olds “don’t see a point in saving until things return to normal.” Some Gen Zers have even adopted the mentality that “money isn’t real” and are justifying spending on items to “treat themselves” amid a bleak reality.

Patterns of Surface Warming Matter for Climate Sensitivity One of the grand challenges in climate science is to reduce uncertainty in estimates of climate sensitivity, which quantifies how much Earth’s surface warms in response to a doubling of carbon dioxide relative to preindustrial levels. This uncertainty is large because climate sensitivity aggregates myriad processes, from microscale aerosol-cloud interactions to planetary-scale atmospheric and ocean circulations, into one number. Clouds, which are notoriously difficult to measure and simulate, are the main driver of the uncertainty. Various lines of evidence are used to estimate climate sensitivity, including climate model simulations of varying complexity, observations over the past century, proxies that measure climate change in the distant past, and theory. The likely range of estimates of climate sensitivity was stubbornly constant at a distressingly imprecise 1.5–4.5 K for several decades, but the research community’s efforts have recently chipped away at this range (Figure 1).

Patterns of Surface Warming Matter for Climate Sensitivity Feedbacks involving clouds and the atmospheric temperature structure are most sensitive to spatial differences in warming. Deep convection in the warmest tropical regions readily communicates surface conditions upward throughout the troposphere (up to about 10–15 kilometers) and then horizontally across much of the globe, making the western Pacific a climate sweet spot. This warmer air sitting atop the relatively cool waters in the eastern Pacific or Southern Ocean acts to stabilize the lowermost troposphere, allowing more extensive low-lying stratus and stratocumulus clouds to develop. Because of their location and structure, these low clouds efficiently cool the planet and offset some of the initial warming (Figure 2, top left). Approaching the Problem from Different Angles Three strands of research have converged over the past few years, highlighting that understanding the pattern effect benefits from contributions from virtually all climate research communities. Historically, three strands of research have highlighted the dependence of radiative feedbacks on the surface warming pattern. The first strand came from analyses of climate feedbacks and sensitivity in model simulations of unequilibrated, transient climate change.

If feedbacks were constant, the expected equilibrium temperature change (climate sensitivity) could be estimated using a very simple energy balance model that linearly extrapolates the relationship between global temperature change and radiative imbalance [e.g., Gregory et al., 2004].

In addition to our growing knowledge of the pattern effect, we also have learned that radiative feedbacks depend on global mean temperature itself: Warming Earth by 1 K from the LGM emphasizes different feedbacks (e.g., the sea ice albedo feedback) than warming by 1 K from a Miocene hothouse world or warming from 4 to 5 K in a high-emission scenario in a century or two from today (e.g., the water vapor feedback [Bloch-Johnson et al., 2021]).

Patterns of Surface Warming Matter for Climate Sensitivity The LGM currently provides the best constraint on the upper bound of equilibrium climate sensitivity [Sherwood et al., 2020], and hence, the details of the pattern effect matter greatly. Outstanding questions concern how representative pattern changes in the past century, the past millennium, or quasi-equilibrated times millions of years ago are of expected future changes. In addition to our growing knowledge of the pattern effect, we also have learned that radiative feedbacks depend on global mean temperature itself: Warming Earth by 1 K from the LGM emphasizes different feedbacks (e.g., the sea ice albedo feedback) than warming by 1 K from a Miocene hothouse world or warming from 4 to 5 K in a high-emission scenario in a century or two from today (e.g., the water vapor feedback [Bloch-Johnson et al., 2021]). The pattern effect and the feedback temperature dependence add uncertainties to estimates of climate sensitivity based on the paleorecord, but quantifying their effects would make these records more relevant to constraining climate sensitivity and expected future warming.

The paleorecord could further be crucial for understanding the timescales and relative importance of internal variability, forced response, and extratropical forcing to rates of warming or cooling in the equatorial Pacific in nature and in climate models.

Should We Trust Model Patterns in Climate Change Scenarios? Our understanding of the pattern effect raises the question of whether climate models can reproduce observed warming patterns. Coupled climate models simulate a freely evolving ocean surface and hence have their own expression of internal variability. For example, we would not expect a coupled model to simulate El Niño events at the same time as they happened in nature, except by chance.
