Underground Climate Change: Shifting Ground in Cities
“Underground climate change threatens city stability as urban ground deformation due to heat absorption causes building cracks.”
Discovering Underground Climate Change
Scientists have recently discovered a new and concerning phenomenon known as underground climate change. This phenomenon is linked to the shifting ground beneath urban areas and has significant implications for the stability and functionality of cities.
Cities are already known for their heat island effect, where they absorb and release heat differently than rural areas. However, it is now understood that cities not only release heat into the air but also into the ground. As the ground heats up, it deforms, causing excessive movement and even cracking of building foundations and the surrounding ground.
A study conducted by scientists at Northwestern University in Chicago revealed these findings. Data collected from sensors placed in basements, subway tunnels, underground parking garages, and subsurface streets supported the conclusions. The researchers expect these issues to persist for years to come.
While underground climate change may not directly pose a safety risk to individuals, it can significantly impact the day-to-day operations of foundation systems and civil infrastructure. Many downtown foundations are experiencing unwanted settlement, leading to a gradual sinking effect. This highlights that living in a sinking city is not limited to places like Venice; cities worldwide can face similar subsidence issues due to different causes.
It is important to understand and address underground climate change in urban planning and infrastructure design to ensure the long-term stability and functionality of cities. Unfortunately, no existing civil structure or infrastructure is designed to withstand the ground deformations caused by this phenomenon. Increased awareness, research, and mitigation efforts are necessary to tackle this silent hazard and protect urban environments from its consequences.
The study, published in Nature Communications Engineering, emphasizes the need for further research and consideration of underground climate change in urban development. By addressing this issue, cities can better prepare for the long-term effects and ensure the resilience of their infrastructure in the face of changing climatic conditions.

College Life
Campus diversity is becoming difficult to measure as students keep their race and ethnicity hidden on college applications
When the Supreme Court struck down race-based admissions at American colleges and universities just over a year ago, many predicted U.S. campuses would become much less diverse. But in part due to students who decide not to disclose their race or ethnicity, coupled with universities’ selective use of statistics, it is not clear how much the decision has affected diversity on campus.
As higher education institutions begin reporting the racial makeup of the class of 2028 – the first to be affected by the 2023 decision – the data is hard to interpret, confusing and inconclusive.
As a sociologist who has studied how institutions of higher education collect and report data on race and ethnicity, I have identified some factors that contribute to this lack of clarity.
Students don’t identify with choices given
Some students may not select a racial or ethnic category because they don’t believe any of the categories really fit. For example, before multiracial students could select “one or more,” an option that became widely available in 2010, they were more likely to decline to identify their race or ethnicity. Some even boycotted checkboxes entirely.
Other students don’t view their race as important: 67% of the students who choose “race and ethnicity unknown” are white. Of these students, 33% say race and ethnicity are not a relevant part of their identity, a researcher found in 2008.
The number of students who don’t respond to questions about race or ethnicity – and are listed in the “race unknown” category – is increasing. At Harvard University, for example, the percentage of “race-unknown” undergrad students doubled from 2023 to 2024.
As the number of “race unknown” students grows, it not only becomes harder to determine a student body’s ethnic and racial diversity but also the impact of the ban on race-conscious admissions.
Fearing discrimination, students don’t disclose race
Some students believe their race or ethnicity will harm their chances of admission.
This is particularly true at many selective institutions, which have higher nonresponse rates than less selective institutions, about 4% compared with 1% to 2%.
My research shows that students are even more likely to pass on identifying race or ethnicity at selective law schools, where race and ethnicity could be used among a variety of criteria for admissions before the Supreme Court ruled against that practice. An average of 8% of students at those schools chose not to identify, compared with 4% at less selective law schools.
‘We’re very diverse’: University decisions distort statistics
What a university chooses to report will also affect the student body demographic data the public sees. Harvard, for example, does not report its proportion of white students.
Some institutions use statistics strategically to appear more diverse than they are. These strategies include counting multiracial students multiple times – once for each race selected – or including international students as a separate category in demographic pie charts. The greater the number of different-colored slices on the chart, the more demographically “diverse” an institution appears to be.
Impact of Supreme Court ruling: Clearer picture coming soon
While universities may not all report their student demographics the same way in their own materials, they all have to report it the same way to the federal government – namely, to its Integrated Post Secondary Education Data System, better known as IPEDS. The next IPEDS report on characteristics for the 2024 enrollment class is expected to be released in spring 2025. Once that data is available, a better picture of how the Supreme Court’s decision has affected diversity in college enrollment should emerge.
That clearer picture might not last long. In 2027, the federal government will require colleges and universities to make changes to how they report student race and ethnicity. Among the changes is the addition of a Middle Eastern and North African category. Under the current standard, Middle Eastern and North African students are counted as white. As a result, white enrollment at some colleges and universities will appear to decline after 2027.
The new standards will also change the way universities treat Hispanic or Latino ethnicity on enrollment forms. Today, if students self-identify as Hispanic and white, they will be categorized as Hispanic. If students select Hispanic and white in 2027, they will be categorized as multiracial. The revised categories will muddy the impact of the Supreme Court’s decision. A drop in the number of Hispanic students reported could be due to the court’s ruling. Or it may result from the new way students will be counted.
Until universities and colleges adjust to the new guidelines about collecting and reporting race – and as long as students decline to provide their racial identities – the full effect of banning consideration of race in college admissions will remain a cloudy picture at best.

Republican lawmakers will reshape tax policy in 2025 — a tax expert explains what to expect
Jim Franklin, Western Governors University School of Business
Although coverage of the 2024 election was dominated by the economy, taxes didn’t get much attention in the run-up to the vote. That’s a bit of a surprise, since 2025 will be a major year for America’s tax system – in fact, the fate of the most significant tax reform in three decades hangs in the balance.
That would be the Tax Cuts and Jobs Act, which Congress passed during President-elect Donald Trump’s first term in office in 2017. If lawmakers don’t take action, the whole package is set to expire at the end of next year. Western Governors University School of Business tax expert Jim Franklin explains what might be in store for the act, and for taxpayers.
What do the election results mean for Republicans’ ability to advance their tax agenda?
We know there will be a Republican president, and it appears the Republican Party will have the majority in both chambers of Congress. That means Republicans will be able to pass a tax bill along party lines, similar to how Democrats passed the Inflation Reduction Act using budget reconciliation.
This would allow Republicans to pass key policies with a simple majority. The Republican majority is narrow, so it will be interesting to see how the leaders unify their constituent groups.
Republicans have traditionally supported lower tax rates for businesses and individuals, as well as tax incentives to help boost economic activity.
What’s next for the Tax Cuts and Jobs Act?
Currently, the act is set to expire at the end of 2025, but Trump and Republicans favor renewing many of its provisions.
The nonpartisan Congressional Budget Office in May 2024 estimated that extending the act would cost the government US$4.6 trillion, and there’s a split within the party, with one bloc of congressional Republicans calling for a full extension and another asking for the balancing of tax policy and annual federal deficits.
Republicans are likely to fight to keep key components in place, including the higher standard deduction, reduced corporate tax rates, individual rate cuts and an increased estate tax exemption.
There’s even talk of lowering the corporate tax rate further, possibly to 15% for domestic production, which would be a significant move.
What other tax measures are Republicans considering?
Trump mentioned a variety of tax relief ideas on the campaign trail, including exempting tips, Social Security benefits and overtime pay from income taxes, and creating an itemized deduction for auto loan interest.
However, Republicans aren’t entirely unified on tax policy. Some deficit hawks are concerned about revenue losses, so there could be internal pushback on all these points. The real question is whether there will be enough opposition within the party to alter or block certain proposals.
But I expect many parts of the act to be renewed, and we may see some additions. For example, there’s been a lot of pressure around increasing the state and local tax deduction cap, also known as SALT, which has bipartisan support in states with higher state income taxes like New York, California and Illinois. It will be interesting to see if that gains any traction. There’s a lot of pressure among representatives, both Republicans and Democrats, to gain some relief in that area.
Where will they find revenue?
Good question. Observers are indicating that Republicans are likely to look at cutting green energy subsidies from the 2022 Inflation Reduction Act. These could be eliminated to help balance out the cost of their new tax proposals.
Another area to watch is tariffs. There’s talk of raising tariffs on Chinese goods — potentially up to 60% — and even imposing a universal tariff on all U.S. imports at a 20% rate. It will be interesting to see how this plays out. Will it be more targeted? For example, will there be continued tariffs on select imports such as automotive imports from China to protect the U.S. electric vehicle market?
What will you be watching between now and Tax Day?
One factor will be Trump’s cabinet appointments. Whoever he nominates for Treasury secretary, for instance, could have a big influence. They can help shape what the tax bill looks like. Another key factor will be who ends up on the congressional tax committees. The composition of key committees will affect the direction of policy and the specific details.
What do you think will happen with tariffs?
Tariffs are unpredictable: They could be applied broadly, or more selectively. It could be similar to the way that Trump and his first administration placed some tariffs on steel, aluminum and solar panels. Interestingly, many of the tariffs were retained by the Biden administration.
Blanket tariffs could slow down the economy, so there is always a risk. Tariffs impact inflation because they affect the cost of imported goods, which would likely reduce consumers’ purchasing power. Domestic political pressure will play a role, as higher tariffs could raise prices on many goods that are imported, including essential products like medications.
Do you have advice for people struggling to keep up with the latest tax news?
Observers often take every policy suggestion on the campaign trail literally — exempting tips, Social Security benefits, overtime pay, etc. — as if all these proposals will pass exactly as stated. But the details matter, and policies are rarely implemented without adjustments. So it’s wise to read beyond the headlines.
