Stor­ing CO2 un­der North Sea ‘can help cut global warm­ing’

Daily Express - - NEWS - By En­vi­ron­ment Ed­i­tor

THE world is on track to tackle cli­mate change by stor­ing car­bon diox­ide emis­sions un­der­ground, ex­perts claimed yes­ter­day.

There is al­ready four times as much ca­pac­ity to store the green­house gas than is needed to meet even “am­bi­tious” tar­gets, said an Im­pe­rial Col­lege Lon­don team.

A sep­a­rate study said trop­i­cal forests are more re­silient to global warm­ing than pre­vi­ously thought.

Change’s strat­egy to con­trol green­house gas emis­sions.

It in­volves trap­ping CO2 at its emis­sion source to stop it from en­ter­ing the at­mos­phere. One op­tion is to pump the gas into old North Sea oil and gas fields.

Dr Christo­pher Za­hasky, of Im­pe­rial Col­lege, said: “Our study shows that if cli­mate change tar­gets are not met by 2100, it won’t be for a lack of car­bon cap­ture and stor­age space.” The study ap­peared in jour­nal En­ergy & En­vi­ron­men­tal Sci­ence.

The re­silience of rain­forests was re­vealed in the jour­nal Sci­ence by Dr Martin Sul­li­van, from the Univer­sity of Leeds.

He said: “Our anal­y­sis re­veals that – up to a cer­tain point of heat­ing – trop­i­cal forests are sur­pris­ingly re­sis­tant to small tem­per­a­ture dif­fer­ences.

“If we limit cli­mate change, they can con­tinue to store a large amount of car­bon.”
