of an­cient CO2 lev­els can be found in the bubbles held within Antarc­tic ice. Sci­en­tific inquiry into fos­sil life and ge­o­log­i­cal events has also brought about a greater un­der­stand­ing of the changes in Earth’s at­mos­phere through­out our planet’s ex­is­tence.

At day­break, if you look to­wards the ris­ing sun, you may see the bright planet Venus. Through satel­lite and ro­botic ex­plo­rations of this planet, we now un­der­stand what causes the in­tensely hot tem­per­a­tures at the sur­face – the green­house ef­fect of car­bon diox­ide and water vapour. Ac­cord­ing to a re­cent NASA re­port, Venus may have once been a hab­it­able planet, un­til global warm­ing trans­formed the planet into its cur­rent hellish state with sur­face tem­per­a­tures higher than 460°C, vir­tu­ally no water, and an at­mos­phere com­prised of car­bon diox­ide and sul­phuric acid clouds.

To­day, count­less sci­en­tists are ob­serv­ing Earth’s at­mo­spheric dy­nam­ics. While there may be a con­cern­ing num­ber of cli­mate change de­niers, their num­bers are vastly out­num­bered by those who hold to the science, and by those who are suf­fer­ing from its ef­fects. The real con­tro­versy sur­round­ing cli­mate change is there­fore not about chem­istry and the science of the cli­mate, but about re­spon­si­bil­ity and jus­tice.

Op­por­tu­ni­ties for change

It would be too easy to be­come com­pla­cent, or even de­featist, in the face of these wor­ry­ing changes. But there is still an op­por­tu­nity for ev­ery in­di­vid­ual to work to­gether to set mo­tions in place. First and fore­most, we need to un­der­stand and stay alert to the prob­lem. Only then can we give it the at­ten­tion and grav­ity that it de­serves. There’s a re­mark­able amount of con­fu­sion and, trag­i­cally, mis­in­for­ma­tion about cli­mate change. For some, it’s eas­ier to deny or ig­nore these changes and to re­sist mak­ing any tough de­ci­sions, but this is, in­evitably, a los­ing strat­egy.

With that aware­ness comes a recog­ni­tion of the path­ways for­ward. Re­al­is­ing that re­new­able en­ergy sources such as wind, hy­dro, and so­lar en­ergy of­fer new so­lu­tions for gen­er­at­ing power, in­no­va­tive coun­tries have in­vested in re­search and in­sti­gated in­fra­struc­ture ef­forts to­wards im­ple­ment­ing these tech­nolo­gies. Fos­sil fu­els are be­ing iden­ti­fied not only as non-re­new­able, but also as per­ilous, lead­ing to in­creased calls for re­duc­ing re­liance on these im­por­tant re­sources.

Across the globe, peo­ple are ex­per­i­ment­ing with new meth­ods to slow, mit­i­gate, and adapt to cli­mate change. While these ini­tia­tives are as yet un­able to pro­vide a ca­pa­ble re­place­ment for fos­sil en­ergy sources, used ef­fec­tively, they may lead to a fu­ture where hu­man­ity is able to har­ness the tools to man­age our shared at­mos­phere more re­spon­si­bly.

Change starts with you

What can you do? You can choose a course of ac­tion that helps hu­man­ity adapt to and bet­ter un­der­stand the chal­lenges of the fu­ture. De­mand and use al­ter­nate en­ergy sources. Be proac­tive in help­ing your com­mu­nity plan for the com­ing changes. You can be trans­par­ent about and aware of your own en­ergy con­sump­tion, and be cog­nisant of your na­tion’s en­ergy use; in­sist that your po­lit­i­cal lead­ers con­front the is­sues re­spon­si­bly. Shun the easy mindset of de­nial, and be em­pa­thetic to those peo­ple who face the ef­fects of cli­mate change on the front lines. Un­der­stand the cur­rent cri­sis by re­search­ing the ge­o­log­i­cal past. Con­tex­tu­alise. Plant a tree. Be cre­ative, be ra­tio­nal, and be bold in your daily de­ci­sions in how to in­di­vid­u­ally re­duce your car­bon footprint.

When the first pho­to­graph was taken of Earth by Apollo 17 in 1972 – called The Blue Mar­ble – hu­mans had their first clear im­age of the beautiful vul­ner­a­bil­ity of our planet, or­bit­ing silently in space. This im­age cap­tures our at­mos­phere, and shows that it is shared by all of us. If there is one sure thing that arises from the un­cer­tainty of a chang­ing world, it is the sin­gu­lar im­por­tance of that fact. Earth is our one and only hos­pitable habi­tat – one that we won’t have the op­por­tu­nity to be home­sick for should we choose to lose it. ag
