Kan­sai Inter­na­tion­al Air­port is one of the ten mar­vel­lous engi­neer­ing civ­il struc­ture in the 20th cen­tu­ry. It’s com­plete­ly built on the arti­fi­cial island, 3 mile from shore, pro­mot­ing eco­nom­ic devel­op­ment and avoid­ing res­i­den­tial prob­lems such as great noise and relo­ca­tion. How­ev­er, since it was built, it’ seems to be doomed to sink to the sea. Espe­cial­ly in the cur­rent era, the fate of KIA is more uncer­tain, under the glob­al cli­mate evo­lu­tion. To inves­ti­gate more mon­ey on main­te­nance, or just leave it as it is, it’s a seri­ous question.

To solve the flood­ing issue of the Yangtze Riv­er, a hydro­elec­tric grav­i­ty dam project is pro­posed, which spans the riv­er by the town of San­doup­ing, in Yil­ing Dis­trict, Yichang, Hubei province, cen­tral Chi­na, down­stream of the Three Gorges. The Three Gorges Dam is also the world’s largest pow­er sta­tion in terms of installed capac­i­ty. Nev­er­the­less, its impact on the bio­di­ver­si­ty, foresta­tion, and human habi­tats are nowhere to be neglected.

High-speed rail­way is now gain­ing more and more pop­u­lar­i­ty around the world but USA seems to fall behind Chi­na and Europe in this rev­o­lu­tion. Lots of rea­sons like gov­ern­men­tal struc­ture and eco­nom­ic fund­ing accounts for this lap. How­ev­er, Cal­i­for­nia maybe the first in USA to build a mature high-speed rail­way. This rail­way will not only bring con­ve­nience to peo­ple’s out­ing, but also great­ly reduce the pol­lu­tion, alle­vi­at­ing air qual­i­ty issue in CA, but behind the con­struc­tion process, the road to the rail­way is not easy.

The Trump Wall is an expan­sion of the Mex­i­co-Unit­ed States Bar­ri­er, built for inhibit­ing ille­gal cross­ing of migrants from South Amer­i­ca. The dis­con­tin­u­ous wall stretch­es more than 450 miles on the con­ti­nent, sep­a­rat­ing two coun­tries with nat­ur­al bor­ders and vir­tu­al fence. How­ev­er, not do whether the wall bor­der actu­al­ly reduce ille­gal migra­tion is under ques­tion, but also there are oth­er con­cerns with ille­gal drug trade, envi­ron­men­tal influ­ence, pri­vate prop­er­ty and the deport­ed immi­grants life.

Urban Inte­grat­ed Field Lab­o­ra­to­ries are to be con­struct­ed in three U.S. cities through fund­ing by the Depart­ment of Ener­gy. These Urban IFL projects will aim to bet­ter under­stand the cli­mate chal­lenges affect­ing the des­ig­nat­ed areas and how to address cli­mate adap­ta­tions while tak­ing into account groups that have his­tor­i­cal­ly been underrepresented.

In recent years, the Mer­amec Riv­er has been expe­ri­enc­ing his­toric flood­ing that may be exac­er­bat­ed by the Val­ley Park lev­ee that was built by the Army Corps of Engi­neers and pro­tects an afflu­ent com­mu­ni­ty. Near­by com­mu­ni­ties who are less for­tu­nate, expe­ri­ence fre­quent flood­ing where homes are rou­tine­ly lost and rebuilt at the expense of lack of flood man­age­ment in the area and the near­by lev­ee being built on out­dat­ed models.

In an attempt to sta­bal­ize ener­gy mar­ket and boost domes­tic ener­gy pro­duc­tion, Biden admin­is­tra­tion decid­ed to push for­ward the con­struc­tion of wil­lowtree oil drilling project. How­ev­er, this approval is a betray­al of Biden’s stop­ping oil and gas drilling com­paign promise and rais­es huge objec­tion from pub­lic. The ten­sion also lies with­in the Alas­ka res­i­dents, some think it would fos­ter racial jus­tice, by cre­at­ing job oppor­tu­ni­ties and increas­ing rev­enues, while oth­er con­cerns more about envi­ron­men­tal impacts. Last but not the least, there’s debate over the envi­ron­men­tal con­se­quences of the project itself: will it actu­al­ly lead to more emission?
