the united nations has warned that world temperatures are on track to rise the gap between the emissions cuts needed to limit global warming — and the actual progress being made — has been laid bare in a new report. the un environment programme says the world is currently the un secretary—general has said the world is already paying a terrible price because of climate change. it highlights where the world needs to be to keep temperatures under that 1.5 and in the 2 degrees at the has agreed is at the paris agreement and where we really are and what we have seen in the last year 2023 is a take—up in those emissions and emissions grows globally about 1.3% and it doesn't sound like a lot but compared to what the

previous decade it is considerably more than what's happened in that last year as we have seen people returning to the skies. people flying aviation has increased and people using their cars more and industry ramp up its use of cars as well. taken altogether, the un environment... it will need a herculean effort to bring those emissions down over the next ten years or so to weigh the need to be to keep those temperature thresholds insight. g those temperature thresholds insiaht. �* ., ., those temperature thresholds insiaht. ., ., , ,, insight. a lot of pressure then on the next — insight. a lot of pressure then on the next cups _ insight. a lot of pressure then on the next cups summit - insight. a lot of pressure then on the next cups summit to i insight. a lot of pressure then . on the next cups summit to come up on the next cups summit to come up with some sort of new action plan i suppose? up with some sort of new action plan i surmise?— plan i suppose? absolutely. there is a — plan i suppose? absolutely. there is a number— plan i suppose? absolutely. there is a number of- plan i suppose? absolutely. i there is a number of factors here which complicates the picture to some degree. as well as people using their cars and flying more, the impacts of climate change are making the world warmer and people are using more air conditioning. it's having an impact on hydropower. and also the fact we are trying to transition away and use more electric cars, that is pushing up demand

for electricity. so it's a very complex picture and very difficult for the political leaders who come together in baku next month to be able to solve it. the key focus for them would be to try and find them would be to try and find the money because the money will be the key that will unlock this whole problem in many respects and that is the key focus of this particular meeting. if they can put enough money on the table to transition away from fossil sales and adapt to the impacts of climate change that would be a big step forward but at this moment in time there is predictably no sense of agreement on that. let's speak to professor myles allen, he's the head of atmospheric, oceanic and planetary physics at oxford university. he has also served on the intergovernmental panel on climate change. another dire warning from the un. we've had several in the past. do you think anyone is going to listen this time? i think it's important to be clear_ think it's important to be clear to _ think it's important to be

0'donnell listening to people like gus o'donnell and mark carney who are all saying we need to invest more to grow our economy and sees that he was opportunities there are in digital, tech, life sciences and clean energy but we will only be able to do that if we change the way that we measure debt. let's speak to our chief political correspondent, henry zeffman. change the measure of debt she says. just translate that into basic english for our viewers. what is she talking about? the government will retain rules about essentially reducing debt and not using borrowing to fund day—to—day spending but what exactly they mean by debt will change. i'm not sure this is going to mean translating it into basic english but what they are going to do is incorporate more financial assets into that measure of debt so they're going to include the student loan book, they're going to include share

stakes in companies and ultimately what this net financial liability is tells you is that in the run—up to this budget money is tight and rachel reeves, the relatively new chancellor, is eager to give herself more room to invest in public services. people reckon that this extensive settled tweak will free up about £50 billion more for the government to spend. i don't think we are going to spend it all at once in this budget but it these are some of the pressure as the chancellor makes what she keeps calling difficult decisions. it’s makes what she keeps calling difficult decisions.— difficult decisions. it's quite handy accountancy - difficult decisions. it's quite j handy accountancy measure difficult decisions. it's quite i handy accountancy measure in difficult decisions. it's quite - handy accountancy measure in a sense? . , , handy accountancy measure in a sense? ., , , �* handy accountancy measure in a sense? . , , �* ~ sense? undeniably. but i think there is also _ sense? undeniably. but i think there is also an _ sense? undeniably. but i think there is also an economic- there is also an economic argument that the government wants to make and hopes to win and it's about the necessity as they see it of borrowing in order to invest. borrowing has

been such a dirty word for so long in british politics, probably back since the financial crisis. rachel reeves is going to try to advance an argument that in the past some party have been uneasy about that borrowing can be good if it entails investing in public services and investing in the public realm. and there is a clear political fault line on this already emerging. we've just had through a response from jeremy hunt, who brave —— predecessor as chancellor, and also the channel chancellor and he said this, let me be clear, the advice i received consistently whilst chancellor was that any additional borrowing would mean higher interest rates for longer. so thatis interest rates for longer. so that is the argument coming into view. labour and the government saying that borrowing is worth it in order to invest in the state. jeremy hunt saying any borrowing or any extra borrowing is bad because it will mean higher interest rates.—

interest rates. that's very useful. thank _ interest rates. that's very useful. thank you - interest rates. that's very useful. thank you for - interest rates. that's very useful. thank you for that analysis. i will put some of those points to the senior research economist at the institute for fiscal studies. what do you make of this announcement changing the measure of debt? it could free up measure of debt? it could free up something like £50 billion. the opposition saying it could end up putting up interest rates. what is your view? i think this is rachel reeves confirming something that has been _ confirming something that has been rumoured for a while which is changing the measure of debt — is changing the measure of debt. we can talk about the measure _ debt. we can talk about the measure of debt but it's actually a side point from what the big — actually a side point from what the big debate is the big debate it should we be borrowing large sums in order to invest _ borrowing large sums in order to invest in things like the railways _ to invest in things like the railways and the hospital buildings and energy infrastructure even if it means more — infrastructure even if it means more debt and more debt servicing and slightly high interest rates? that is the question— interest rates? that is the question and that is the decision in the direction rathei— decision in the direction rachel reeves is taking and
