Acikin 2005, Caldeira ya shiga Cibiyar Kimiyya ta Carnegie na Sashen Kimiyya na Duniya a matsayin babban masanin kimiyya, inda aikinsa shine "yin mahimman binciken kimiyya. Ya kuma yi aiki a matsayin Farfesa (da ladabi) a Sashen Kimiyyar Tsarin Duniya na Jami'ar Stanford.
Caldeira tayi aiki a matsayin memba na kwamitin da ke samar da rahoton Cibiyar Nazarin Kimiyya ta Ƙasa ta Amurka ta 2015, Geoengineering Climate:

A cikin 2007, Caldeira ya fara ba Bill Gates shawara kan sauyin yanayi da batutuwan makamashi. Acikin sakonsa na ƙarshen shekara ta 2016, Gates ya kira Caldeira a matsayin malamin ban mamaki.Acikin 2021, Caldeira ya fara aiki ga kamfanin binciken makamashi Breakthrough Energy, wanda Gates ya kafa.[4]

An nuna aikin Caldeira a cikin labarin 14 May 2012 acikin New Yorker, mai suna "The Climate Fixers" da kuma a cikin 20 Nuwamba 2006 labarin a cikin New Yorker, mai suna"The Darkening Sea.Acikin 2007, ya bada gudummawar op-ed guda biyu kan batun dumamar yanayi zuwa The New York Times.
Dangane da takaddamar da littafin SuperFreakonomics ya haifar a kan ra'ayin Caldeira game da aikin injiniya na yanayi, Caldeira yaƙi shawarar da yace, "Carbon dioxide ba daidai ba ne".Ya mayar da martani ta hanyar wallafawa a shafinsa na yanar gizo,"Carbon dioxide shi ne mugun da ya dace... matukar dai abubuwa marasa rai na iya zama mugaye." Yace yayin da sauran maganganun da marubuta Steven Levitt da Stephen Dubner suka dangana masa suna "ainihin gaskiya", mai karatu na yau da kullun na iya yin kuskuren abin da ya yi imani da shi [Caldeira].

Acikin 2011, Caldeira yayi murabus a matsayin jagorar marubucin wani babi na IPCC AR5, yana mai cewa "Haka kuma, ina tsammanin IPCC ta kasance da amfani sosai a baya, kuma na yi imanin IPCC na iya zama da amfani sosai a nan gaba.[. . . ] murabus na ya yiwu ne saboda na yi imani cewa ƙungiyar babi da nake cikinta tana kan hanya madaidaiciya kuma tana yin kyakkyawan aiki ba tare da gudunmawata ba.

Caldeira yayi jayayya da manufar manufofin sifili na hayakin carbon dioxide. A shekara ta 2005, yace, "Idan kuna magana game da murƙushe ƙananan tsofaffin mata, ba ku ce, 'Mene ne burinmu na yawan mugging ƙananan tsofaffi?' Kun ce, 'Karɓar ƴan tsofaffi mata ba kyau ba ne, kuma za muyi ƙoƙari mu kawar da shi.'

Kuma ina ganin a ƙarshe ya kamata mu zo kusa don kallon hayaƙin carbon dioxide iri ɗaya." Acikin 2014, yace, "Lokaci ya yi da za'a daina gina abubuwa da bututun wutsiya da hayaki. Lokaci yayi da za mu daina amfani da sararin sama a matsayin sharar gida don gurɓatarwar carbon dioxide.”
A cikin 2013, tare da wasu manyan masana, ya kasance marubucin wata budaddiyar wasika ga masu tsara manufofi, wanda ya bayyana cewa "ci gaba da adawa da makamashin nukiliya yana barazana ga ikon bil'adama na guje wa sauyin yanayi mai haɗari."
