It's good morning, everyone.
I'm very pleased to welcome you to this press conference where we present findings from the World Meteorological Organisation State of Climate Report for 2025.
My name is Nandita Surendran and I'm the new Chief of Communications at WMO.
I'm very happy to be in Geneva and I look forward to working with you all.
My thanks also to UNTV for hosting us today.
The State of Climate report is being launched on World Meteorological Day, which is on Monday, the 23rd of March.
A reminder, therefore, that this press briefing and the contents of the report are under embargo until O 500 CET on Monday.
The press release is available in official UN languages and we also have data sets and multimedia material that's available for your use.
The State of Climate report is our annual check in, in a sense, on the state of the global climate, key climate indicators and their impacts.
This comprehensive report is produced by WMO in collaboration with national meteorological and hydrological services agencies, international data centres, climate research institutions and of course, UN partners.
Many of you may recall that a snapshot of these headline messages was presented at the Climate Corp last year.
Today we present to you the full picture for 2025.
I understand we have about 30 minutes today and beside me and online are our speakers and their remarks and presentations will be followed by AQ and A.
So introducing you to our panellists, we have with us Cole Barrett, the Deputy Secretary General of WMO Online.
We're joined by with by joint John Kennedy, the scientific officer at WMO, and Claire Ransom, the associate scientific officer to my left.
But first, let's hear from the UN Secretary General, Antonio Guterres for his statement on the state of climate 2025.
The state of the global climate is in a state of emergency.
Planet Earth is being pushed beyond its limits.
Every key climate indicator is flushing red.
That is the clear message of the latest report from the World Meteorological Organisation.
The report confirms that the Earth's energy imbalance, the gap between heat absorbed and heat released, is the highest on records.
In other words, our planet is trapping heat faster than it can shed it.
Greenhouse gases concentrations are higher than at than at any point in hundreds of thousands of years.
Global temperatures continue to rise, and humanity has just endured the 11 hottest years on records.
When history repeats itself 11 times, it is no longer a coincidence.
Meanwhile, our oceans are absorbing epic levels of heat, fueling ever stronger storms.
Glaciers and sea ice are vanishing, and sea levels are relentlessly rising.
These findings are not confined to charts and graphs.
They are written into the daily lives of people in families struggling as droughts and storms drive up food prices, in workers pushed to the brink by extreme heat, in farmers watching crops wither, in communities and homes swept away by floods.
Those on the front lines urgently need a surge in adaptation finance to face the year and now impacts of the climate crisis.
Climate stress is also exposing another truce.
Our addiction to forcing fuels is destabilising both the climate and global security.
Now more than ever, we must accelerate the just transition to renewable energy.
Renewables deliver climate security, energy security and national security.
Today's report should come with a warning level.
Climate chaos is accelerating and delay is deadly.
The way ahead must be grounded in science, common sense and the courage to act.
I now invite Coe Baron to kick off the discussion.
The state of the global climate is.
Hello colleagues and thank you for joining us for the launch of the World Meteorological Organisation Annual Report on the State of the Global Climate.
With all that's going on in the world, we welcome your focus on the scientific information we'll we will share with you today.
As the scientific voice on weather, climate and water, WMO has been issuing State of the Global Climate reports for more than 30 years to share the annual evidence basis for our key global indicators.
My colleague will walk us through the findings in the report in detail, but I would like to hit on just a few of our findings in my opening remarks.
This report confirms that 2025 was the second or third hottest year on record, depending on the data set used.
It was about 1.43° C above the 1850 to 1900 baseline.
Between 2015 and 2025, we experienced the hottest 11 years on record.
In 2025, our glaciers continued to retreat and ice continued to melt.
The warming ocean and melting land based ice are driving the long term rise in global mean sea level rise.
Extreme events, including intense heat, heavy rainfall and tropical cyclones created challenges for virtually every continent and are a key way that societies are experiencing a changing climate.
The ocean continues to warm and absorb carbon dioxide, playing a fundamental role in the climate system.
Ocean heat content reached a new record high in 2025.
My colleague will also tell you about an indicator we are including, for the first time this year, the Earth's energy imbalance, which measures the rate at which energy enters and leaves the Earth's system.
Under a balanced system, incoming energy from the sun is about the same as the amount of outgoing energy.
This is not the case at present.
These findings inspire us to work harder to get life saving forecasts and early warnings into the hands of those who can protect lives and livelihoods, identifying trends that can inform planning and decision making.
And This is why we monitor the state of the climate.
We are releasing the State of the Global Climate report for World Meteorological Day on on the 23rd of March.
It has the theme observing today, protecting tomorrow.
And with that, I will turn to my colleague, Doctor John Kennedy to walk us through the report.
So should I show the slides from this side or will they be shared there?
So I will go through some of the key indicators and key messages from the report.
So the first of those key messages will be key indicators is the related to greenhouse gases.
So we start with the greenhouse gases and the concentrations of three key greenhouse gases.
So carbon dioxide, methane and nitrous oxide reached record levels in 2024, which is the last year for which we have consolidated global numbers.
And the graph here shows the annual concentration of carbon dioxide in the atmosphere from 1984 to 2024.
And you can see that 2024 was a record high in this record.
It was also the single biggest one year increase in the record.
And data from individual sites around the world indicates that levels of these greenhouse gases continue to increase in 2025.
Now these greenhouse gases along with aerosols and other things in the atmosphere and modifying the energy balance of the planet.
So in the next slide, please, we have our new climate indicator here, which is the Earth's energy imbalance.
And to illustrate what this is, we have this schematic diagram on the right.
And Earth's energy imbalance is fundamentally measuring the rate at which the Earth's system is gaining or losing energy.
So in a stable climate, one that's in balance, the energy coming in from the sun is balanced by the energy going out from out from the climate system.
There's no gain or loss of energy in the long term.
However, in the current climate, there is an imbalance.
We have the same amount of incoming energy, but there's less outgoing energy due to the increased concentrations of greenhouse gases.
And that imbalance with more energy coming in and going out means the energy is accumulating in the Earth's system.
And the Earth's energy imbalance is positive.
And if the Earth's energy imbalance is positive, that means the Earth is warming.
And if it's negative, the Earth is cooling.
And what we've seen since 1960 is not just that the Earth's energy imbalance is positive, which means the Earth is warming, but it's also been increasing since 1960.
And the rate of increase was around 0.13 watts per metre squared per decade the period 1960 to 2025.
But lately it was higher for the period 2001 to 2025, around 0.3 watts per metre squared per decade.
Now that energy is not accumulating evenly on the right hand side here we kind of have these red globes which show where the energy is going.
91% of that accumulating energy is going into the oceans, 3% of it is going into melting and warming ice, 5% is being absorbed by the land, and 1% is going to warming the atmosphere.
So the largest fraction of that absorbed energy is going into the oceans, around 90% of the excess energy in the climate system.
And this matters because over 3 billion people depend on these marine and coastal resources for their livelihoods.
They're living off the ocean and nearly 11% of the global population live on low lying coasts directly exposed to postal hazards, so they're very vulnerable to things like sea level rise.
So how is that energy changing the oceans?
So the first of our indicators related to the ocean is the ocean heat content, which is a direct measure of the energy absorbed by the upper 2000 metres of the ocean.
And the graph here shows the annual ocean heat content from 1960 to 2025.
There's a difference from the 2005 to 2025 baseline from four different data sets, and you can see that all four of these data sets are very similar changes, and you can see that each 12025 was the highest ocean heat content on record.
Another thing to note here is that the rate of ocean warming over the past two decades, so 2005 to 2025, is more than twice that observed.
Over the period 1960 to 2005.
The rate of warming has been increasing, which is what we also see in the Earth's energy imbalance.
Now as this ocean water warms, it expands, and that's driving an increase in sea level rise, which also has other contributions from melting ice on land and the transfer of water from the oceans to the land and vice versa.
So in our next slide, please, we have the global means sea level change, which is our next indicator.
So here you can see global means sea level from 1993 to 2025.
So this is based on data from satellite altimeters measuring on a roughly 10 day cycle, and you can see the clear increase in sea level over this.
In fact, the rate of sea level rise is higher from 2012 to present than for the period 1993 to 2012, which shows the long term rate of sea level rise has actually increased during this period.
Now in 2025, despite the continued ocean warming and melting of ice, the rise in sea level was limited by natural variability.
And part of that was the switch from El Nino, which was in sway at the start of 2024, to La Nina, which we had at the start and end of 2025.
And during La Nina, you tend to see a shift of rainfall over the land and a temporary transfer of water from the oceans to the land, which leads to a drop or pause in sea level rise.
So it's not just energy that the oceans are absorbing, they're also absorbing carbon dioxide.
It's estimated that the ocean has absorbed around 29% of the carbon dioxide emitted by human activities in the past decade and that absorbed carbon dioxide alters ocean chemistry, leading to, amongst other things, a reduction in ocean pH.
And here we're showing the surface ocean pH annually from 1985 to 2025.
And you can clearly see the long term decline at a rate of around 0.017 pH units per decade.
And also those also here, the relatively large uncertainty indicated by the shaded area.
And this is one of the most sparsely observed indicators.
So moving on now from the oceans to the cryosphere, as I mentioned earlier, around 3% of the energy trapped in the Earth's system is available for melting ice.
So that includes ice sheets and glaciers.
And here we're showing cumulative mass balance since 1970 for a set of reference glaciers, which have long continuous records across 19 mountain regions around the world.
And you can see the long term mass loss or the decline in the graph and it's faster in recent years.
Now mass balance is a measure essentially of the change in the thickness of these glaciers and the units here are more metres water equivalents, which corresponds 1 metre water equivalent corresponds to around 1 tonne per square metre of mass loss across the area of these glaciers.
Now in 2024-2025 hydrological year, glacier mass balance was one of the five largest on record and this continues a trend of accelerated glacier mass loss in recent years with eight of the 10 most negative glacier mass balances occurring since 2016.
So ice isn't just melting over the land, it's melting over the oceans as well.
So here we have sea ice extent for the Arctic at the top and Antarctic at the bottom showing annually from 1978 to 2025.
And we're showing a difference here from the 1991 to 2020 average for three different data sets, which again show very similar long term trends and year to year changes.
So in the Arctic at the top, there's a clear long term decrease in the CIS extent and 2025 was the lowest or second lowest annual average extent on record depending on which of these three data sets you look at, 2020 had a very similar extent.
Now in the Antarctic at the bottom here, the long term behaviour is quite different.
There was an increase to a maximum around 2014 and since then there's been a large drop.
This year, 2025, was the third lowest extent on record after 2023 and 2024.
And the past four years, we've seen the four lowest Antarctic sea ice minima on record.
And so our last key indicator here is global mean temperature.
So this represents a part of the 1% of energy that goes to warming the atmosphere, the part closest to the surface.
And the graph here shows the annual global mean surface temperature from 9 data sets.
Again, you can see the agreement between those data sets and it showed us the difference from the 1850 to 1900 baseline which is our standing for pre industrial conditions.
In 2025, globe mean temperature was 1.43 ± 0.13° above the pre industrial average.
And depending on which of these nine data sets you look at, 2025 was either the second or third warmest year on record.
So 2025 was slightly cooler than 2024.
And again, that reflects a change from El Nino, which gives global temperature a temporary bump up to La Nina, which temporarily suppresses global temperature.
And the past eleven years in all, nine of these data sets are the 11 warmest years on record and the past three years are the three warmest.
They're not necessarily in that order.
So moving now from the global scale to a more regional scale, we have here a map which shows precipitation totals for 2025 and it's categorised according to how wet or dry each area was.
So unusually wet areas which would have been in the top 20% of rainfall over the base.
And unusually dry areas which would have been in the driest 20% are shown in brown.
So you can see a very large coherent area of wetter than average conditions over the maritime continent in Southeast Asia, parts of North Australia and that's typical for La Nina.
Similarly, we see wetter conditions over South Africa and parts of the Sahel and drier conditions in the greater the whole of Africa, which are also typically associated with La Nina conditions.
You can also see very dry conditions in Southwest Asia and parts of the Middle East.
So Southeastern Europe as well as northern parts of North America and unusually wet areas also included Southern Asia and many other parts of the Asian continent as well as localised areas around the world.
So some of these excesses in precipitation and lack of precipitation are reflected in the key weather and climate events in 2025.
So the report also lists selected high impact events.
I don't have time to go through all of these in detail.
It's a lot more detail in the report based on information from WMO members, National Meteorological and Hydrological Services, as well as information from our UN partners, including IOMUNHCRFAO and WFP, who provide additional information on food insecurity and displacements.
We also have a short article in the report on climate and health.
Now these high impact events highlight the vulnerability of people around the world to extreme weather events and particularly those living in fragile and conflict afflicted regions.
People who are already displaced are also more vulnerable to extreme weather.
And also we're seeing situations where there are multiple events following one after the other, leaving no time for populations to recover.
Now, this list of weather and climate events shown here is by no means exhaustive.
There's a much longer list of events in a supplement to the reports and more individual events are available via an interactive extremes map based on data provided by WMM members.
So that's the last slide I have.
So thank you very much for your attention and I'll hand back to the chair.
So if there are questions from journalists in the room, AFP, please.
Yeah, thank you very much.
And I had a couple of questions.
I was wondering, first, how concerned are you that greenhouse gas emissions seem to have stagnated or are increasing in the US, for instance?
And also, do you have a forecast for El Nino going forward?
And finally, I was wondering if you could say more generally about the situation today with the US and climate, the the focus on climate and how that might be complicating your work.
Are you, are you being pressured in any way to, to try to avoid focus on, on climate or forecasting forward?
So Cole, would you like to take a first crack at that?
What I'd like to do is go to John for the El Nino part and then I'll come back to the others.
So currently we're still in La Nina, although kind of conditions have been kind of moving more towards neutral recently and the forecasts are largely pointing towards neutral conditions by the middle of the year and maybe El Nino is favoured later on in the year.
So what we typically see then with that shift from La Nina to El Nino is an increase in global temperatures, which typically lags behind the peak of changes in the tropical Pacific.
So if El Nino develops later in the year, then we're likely to see maybe elevated temperatures again in 2027.
However, if we have a recent example, 2023, we saw a very rapid transition from La Nina to El Nina with a very rapid spike in global temperature.
So we kind of in a sense waiting and see, waiting to see what happens.
As to greenhouse gases, of course, we're concerned about the level of greenhouse gases.
It's the main driver of kind of the anthropogenic aspects of the changes to the climate system.
If we don't address that that issue, these indicators will continue to be very problematic with regard to the US, I get some of my information in the same way that you do.
There are we don't get, we're not being pressured to forestall our climate activities.
We've been reassured that their data collection, their observations are continuing without interruption and that all data is flowing.
the IT seems that in the last Congressional Budget cycle, many of the funds that were at first reduced for climate science and other science were kind of put back into the budget.
So I think that is a encouraging side through the Congressional Budget process.
So, so yeah, it's a, it's from from the standpoint of our data collection, we're not seeing an impact.
Hello, it's Christiana with the German Press Agency.
The data that you present in this report, do I understand correctly that that has all been released before individually and it's just put together for the bigger picture like the greenhouse gases, the temperatures and so on.
And the other question, this new measure of what was it called again this new measure that's more energy is, is absorbed than released, Isn't that a no brainer?
I mean that's what we have been talking about for 40 years.
What kind of measure is that all of a sudden?
That basically is what we have been talking about all the time.
I don't quite understand how this is different or gives us a new perspective.
And is there any way to quantify that just other than just saying the obvious that more energy is absorbed than than released?
John, would you like to come in first and then call?
So in terms of the data being released before, yes, a number of these indicators have been released individually individual data sets.
What we, what we do in this report is try and bring all of those together.
So bring for some indicators a range of different data sets so we can look at kind of the available evidence in the whole, but also kind of to bring them together so we kind of can tell this coherent story about how the climate is changing and the the Earth energy imbalance, the the no brainer.
Yes, that's fair comments.
I mean, it's pretty clear that energy is accumulating in the Earth system over the long term.
But I think what's particularly interesting for this indicator is not just that it's accumulating, but the rate of that accumulation is increasing.
And in particular, over the past 20 years, there's been some debate recently in the scientific literature and among scientists about whether the rates of global temperature rise is also increasing, accelerating.
And it's very hard to tell just by looking at the global temperature series on its own, say, that that's happening.
And the Earth's energy imbalance is providing an extra part of that puzzle.
So it's showing us that that energy is also accumulating faster.
There's still discussion going on about what the kind of recent changes we've seen in the climate mean for the future, but I think kind of the Earth's energy imbalance is providing an extra part of that puzzle that we haven't previously been able to report on before.
Thanks, John Cole, would you like to come in?
Yeah, just just quickly to add to John's comments.
I mean, I think the, the feedback that we get from the release of this report is that it is really very helpful to kind of have one summary document that provides the pulse of the planet.
But there's also the, I think advantage of seeing the confluence of the evidence.
You know, the way that various data sets, various sources of information are kind of combining to provide a, a picture that is, is consistent across various sources of information.
It's Stephanie Dodd with German TV.
It all sounds pretty dark, like the picture you're painting.
Can you say what kind of room do you still see left for any, like, human change, if there's any at all?
You call different aspects like the the the heat in the ocean as irreversible.
So where do you see the most room left for any action?
It's a really good question.
Cole, would you like to take that and then maybe John can can compliment.
I'm looking at Claire because as as as a member of the our youth cadre, we often are looking for hopeful messages.
This is a bit of a dire picture and you know, we just, it's our job to kind of provide the evidence that we're seeing with the hope that this information will encourage people to take action.
And we use the information to kind of amplify the forecasts we're able to provide and to provide justification for the need for early warning systems so that we can do what we can to ameliorate the the impacts.
But it, you know, there's no denying that these indicators are not moving in in a direction that provides for a lot of hope.
John, do you want to come in?
I don't have much to add to that.
I was going to mention the importance of early warning systems as well.
We have an example from the Philippines in the report this year, which was affected by a series of typhoons and tropical cyclones through the year.
An effective early warning systems there allowed anticipatory actions including ahead evacuations ahead of some of these these typhoons which reduce the impact.
So there is scope to reduce the vulnerability of people to to these kinds of events.
And through these reports we can we can highlight that importance.
The same goes for the the section we have on climate and health, which talks about the changes that can be made to reduce vulnerability and impacts from from climate on on health, even though it's it's continuing to happen.
I'm turning to our colleague Claire Ransom, who Full disclosure was born after WMO started monitoring the Earth system.
So, you know, on the question of hope.
I think if I may on that first bit that WMO has been monitoring in this report the state of the climate longer than I've been alive.
That's the first kind of step that what we are doing at WMO that gives me hope is that we do continue to monitor the state of how the planet is progressing.
And beyond that, I think the the scientific community overall, there's still massive gaps in our understanding of how the planet functions and where we get that information.
Really, we need a lot more observations from all around the world and we need a lot more of the scientific community to come together.
So from our side in the science community, I think there's a lot that can still be done.
And I also think that it's, it's really important not to get too caught up in this, that changes are happening that are irreversible.
Because if we lose the hope that there's nothing else to do, we will continue to admit and the changes that we're seeing already will only get worse.
Whereas if we can move beyond the kind of despair that we see in the the sadness that is these indicators, we can limit the extent to which they have drastic changes.
So we can still take action.
All of us, not just in the scientific community, every single one of us every single day can be doing more.
And that's what gives me hope as a young person and as somebody that's within the WMO community.
And I can see another question here.
And just a follow up on that.
I, I was, it was good to have a bit of optimism towards the end there.
But I was wondering if you could say specifically what it is we can be doing to change, to change this trajectory because it sounds like it's a lot of mitigation around, you know, adjusting and, and reducing the health impacts or, or vulnerabilities to extreme weather.
But you know, what specifically should people be doing and what should countries be doing?
Could you if you could say thanks to to shift the climate story?
I couldn't tell if your question was back to Claire or not, but OK.
I mean, you know, let's just talk about what this report is and what this report isn't, right?
So this report is our perspective of the evidence that we are directly involved in just kind of measuring the pulse of the planet.
There's not very much in this report about the specific actions that we're that would be recommended or anything.
That's not really our role here, although there is plenty of information, you know from from others and even from ourselves in some of our other reports about climate services etcetera that do point to actions we that can be taken in this report.
You talk well even in this press conference.
We're talking about the way that we use this information to act with our national hydrological and meteorological agencies to use our forecasting and other information to provide the kind of early warning that communities require.
So that in the case, for example, of extreme events, we are really doing all that we can to work with disaster management agencies on the ground to get them this information through our forecasts so that people can be moved out of harm's way to the extent possible.
If there are no more questions, we'll close this press conference.
Thank you for your time and your interest.
Please reach out to us for any follow-ups that you may have and we'd be happy to support.
And, and once again, thank you all for joining us.
