This.s.udy determines.if there is.a correlation b.tween ris.ng carb.n dioxide levels.and glob.l warming. His.orical data were reviewed from three different time periods.s.anning 500 million years. It s.owed that the curves.and trends.were too dis.imilar to es.ab.is. a connection. Ob.ervations.from COs.b.2s.b./temp ratios.s.owed that the COs.b.2s.b. and the temperature moved in oppos.te directions.42% of the time. Many ratios.dis.layed zero or near zero values. reflecting a lack of res.ons.. As.much as.87% of the ratios.revealed negative or near zero values. which s.rongly negate a correlation.

The Cloud Model for Climate Change

International Journal of Geos.iences 2024年第5期15卷 366-395页

作者： Michael Nels.n David b. Nels.n Retired Pleasanton CA USA

In 1995, the Intergovernmental Panel on Climate Change (IPCC) releas.d a thermodynamic model b.s.d on the Greenhous. Effect, aiming to forecas. glob.l temperatures. This.s.udy delves.into the intricacies.of that model. s.me interes.ing ob.ervations.are revealed. The IPCC model equated average temperatures.with average energy fluxes. which can caus. s.gnificant errors. The model as.umed that all energy fluxes.remained cons.ant, and the Earth emitted infrared radiation as.if it were a b.ackb.dy. Neither of thos. conditions.exis.s. The IPCC’s.definition of Climate Change only includes.events.caus.d b. human actions. excluding mos. caus.s. s.tellite data aimed at the tops.of clouds.may have inferred a high Greenhous. Gas.ab.orption flux. The model s.owed more energy coming from the atmos.here than ab.orb.d from the s.n, which may have caus.d a violation of the Firs. and s.cond Laws.of Thermodynamics. There were unexpectedly large gaps.in the s.tellite data that aligned with various.ab.orption b.nds.of Greenhous. Gas.s. pos.ib.y caus.d b. photon s.attering as.ociated with re-emis.ions. b.s.d on s.ience, we developed a cloud-b.s.d climate model that complied with the Radiation Laws.and the Firs. and s.cond Laws.of Thermodynamics. The Cloud Model s.owed that 81.3% of the outgoing reflected and infrared radiation was.applicab.e to the clouds.and water vapor. In comparis.n, the involvement of COs.b.2s.b. was.only 0.04%, making it too minus.ule to meas.re reliab.y.

The prevalence of human immunodeficiency virus.(AIDs. and hepatitis.b.virus.among heavy truck drivers.and their as.is.ants.has.b.en well documented glob.lly in correlation with their b.havioral characteris.ics. The pres.nt s.udy aimed to s.reen for human immunodeficiency virus.(HIV), hepatitis.b.virus.(Hb.), and b.havioral characteris.ics.among heavy truck drivers.in Port s.dan. A cros.-s.ctional s.udy was.conducted on 274 heavy truck drivers.and their as.is.ants.who us.d the highway Port s.dan-Khartoum in Port s.dan city during 2019-2021. Data on b.havioral characteris.ics.and s.b.tance us. hab.ts.were collected us.ng a s.ructured ques.ionnaire, and an ELIs. tes. was.us.d to s.reen for HIV and Hb. infections.in the s.udy participants. The chi-s.uare tes., odds.ratio, and confidence intervals.were us.d to find the as.ociation b.tween b.havioral characteris.ics.and s.ropos.tive HIV/Hb.. Of the 274 enrolled participants. the s.roprevalence rates.of HIV were 2.7% and Hb. was.23.7%. Ninety-four (34.3%) of them had a his.ory of high-ris. s.xual b.havior outs.de of marriage;only two (0.7%) us.d condoms.14.2% of participants.reported alcohol us.;and 1.1% reported drug us.. Univariate analys.s.revealed that having a s.x his.ory outs.de of marriage with ≥1 s.x partner and never us.ng a condom with a s.ous. or cas.al partner were s.gnificant ris. factors.for HIV and Hb. among drivers. Fortunately, we found that mos. of the drivers.reported low alcohol and drug us.. Concerning this.s.udy, the s.roprevalence of HIV and Hb. is.highly as.ociated with a his.ory of having s.x outs.de of marriage and s.xual b.havior among truck drivers.and as.is.ances. Additional s.udies.are needed to further inves.igate other s.Is.and b.havioral characteris.ics.as.ociated with factors.in truck drivers.as.is.ance in different truck s.op regions.in s.dan.
