as the announcement of the uk government's net—zero plans coincided with fresh warnings about melting antarctic ice. a new report has warned rapidly melting is causing a dramatic slowdown in deep ocean currents which could have a disastrous effect on the climate. dr liz thomas is head of ice core research british antarctic survey. to just help us to understand what the impact of this is on those deep water currents that i mention and why they are so important.- water currents that i mention and why they are so important. high. so the really important _ why they are so important. high. so the really important thing _ why they are so important. high. so the really important thing about - the really important thing about this study— the really important thing about this study in _ the really important thing about this study in about _ the really important thing about this study in about focusing - the really important thing about this study in about focusing on i the really important thing about. this study in about focusing on how the oceans — this study in about focusing on how the oceans are _ this study in about focusing on how the oceans are changing _ this study in about focusing on how the oceans are changing in- this study in about focusing on how the oceans are changing in relation| the oceans are changing in relation to the _ the oceans are changing in relation to the amount _ the oceans are changing in relation to the amount that _ the oceans are changing in relation to the amount that we _ the oceans are changing in relation to the amount that we are - the oceans are changing in relation to the amount that we are seeing i to the amount that we are seeing from _ to the amount that we are seeing from the — to the amount that we are seeing from the and _ to the amount that we are seeing from the and arctic _ to the amount that we are seeing from the and arctic ice _ to the amount that we are seeing from the and arctic ice sheet - to the amount that we are seeing from the and arctic ice sheet is l from the and arctic ice sheet is because — from the and arctic ice sheet is because the _ from the and arctic ice sheet is because the oceans _ from the and arctic ice sheet is because the oceans are - from the and arctic ice sheet is| because the oceans are actually from the and arctic ice sheet is i because the oceans are actually a global— because the oceans are actually a global conveyor _ because the oceans are actually a global conveyor. so _ because the oceans are actually a global conveyor. so changes - because the oceans are actually a global conveyor. so changes in. because the oceans are actually a i global conveyor. so changes in the oceanic— global conveyor. so changes in the oceanic circulation— global conveyor. so changes in the oceanic circulation and _ global conveyor. so changes in the oceanic circulation and one - global conveyor. so changes in the oceanic circulation and one part. global conveyor. so changes in the oceanic circulation and one part of| oceanic circulation and one part of the globe — oceanic circulation and one part of the globe will _ oceanic circulation and one part of the globe will have _ oceanic circulation and one part of the globe will have a _ oceanic circulation and one part of the globe will have a big - oceanic circulation and one part of the globe will have a big impact . the globe will have a big impact everywhere _ the globe will have a big impact everywhere. in _ the globe will have a big impact everywhere. in the _ the globe will have a big impact everywhere. in the studies - the globe will have a big impact everywhere. in the studies we i the globe will have a big impact . everywhere. in the studies we are seeing _ everywhere. in the studies we are seeing is — everywhere. in the studies we are seeing is showing _ everywhere. in the studies we are seeing is showing that _ everywhere. in the studies we are seeing is showing that as - everywhere. in the studies we are seeing is showing that as an - everywhere. in the studies we arei seeing is showing that as an article is melting, — seeing is showing that as an article
