Global temperatures may top 1.5C in next five years, says UN agency
The world is expected to experience more record temperatures over the next five years, with Arctic warming predicted at more than three times the global average, a new report by the UN weather agency said.
There is an 80% chance that at least one of the next five years will see record heat, with a high likelihood that average warming will exceed 1.5 degrees Celsius above pre-industrial levels, according to the report by the World Meteorological Organization (WMO).
Last year, the hottest year on record, saw the first breach of the 2015 Paris climate agreement, which committed countries to avoid global warming of more than 1.5 C.
From this year until the end of 2029, the mean near-surface temperature globally is forecast to be between 1.2C and 1.9C higher than pre-industrial levels of the years 1850-1900, the WMO said, adding that this would fuel more extreme weather.
"Every additional fraction of a degree of warming drives more harmful heatwaves, extreme rainfall events, intense droughts, melting of ice sheets, sea ice, and glaciers, heating of the ocean, and rising sea levels," it said in a statement.
In the Arctic, the above-average projected warming will accelerate ice melt in the Arctic and northwest Pacific Ocean.
The report said Arctic warming was predicted to be more than three-and-a-half times the global average, at 2.4C above the average temperature during the most recent 30-year baseline period over the next five winters.
Overall global temperatures will remain at or near record levels until the end of the decade, the WMO report said.
Above-average rainfall is forecast in parts of the world including the Sahel, northern Europe, Alaska and northern Siberia, for the months between May and September between 2025 and 2029, while drier-than-average conditions are foreseen this season over the Amazon, according to the weather agency.

Canadian wildfire smoke seen in Ireland and across Northern Europe
SMOKE from wildfires burning in central Canada has drifted thousands of miles across the Atlantic, arriving in Ireland and other parts of northwestern Europe, according to European climate researchers. The Copernicus Atmosphere Monitoring Service (CAMS), an environmental agency under the European Union's Earth observation programme, has been tracking the movement of wildfire smoke since the start of May. Using satellite data, CAMS confirmed that a large plume originating from the provinces of Manitoba, Saskatchewan and Ontario reached Ireland on Sunday, June 1. Additional plumes are expected to spread further into Europe later this week. 'Wildfires are a frequent occurrence in boreal forests from spring through summer,' said Mark Parrington, a senior scientist at CAMS. 'But the intensity of fires we've seen in Canada this year, particularly in central regions, is extraordinary.' CAMS analysis shows that while the smoke has visibly affected the sky, producing hazy skies and vibrant sunsets, the smoke is travelling at high altitudes, meaning they won't have a major effect on air quality in Europe. However, elsewhere the fires have already caused a lot of damage. More than 25,000 people in Canada have been forced to evacuate, prompting officials in both Saskatchewan and Manitoba to declare month-long states of emergency. U.S. states near the Canadian border have also experienced low air quality as the smoke drifts south. The fires are part of what experts warn could become an intense wildfire season in Canada, exacerbated by ongoing drought, that's also affecting northern Europe.

According to CAMS, carbon emissions from fires in that area have reached their highest levels for this time of year since 2018. Smoke from those Russian blazes has been detected as far away as northeastern China, northern Japan and even the Arctic. While current forecasts suggest only minor health risks from the smoke in Europe, Parrington claimed that the increasing reach of these wildfires add to growing concerns about the long-term effects of climate change and global air quality. Going into further detail Parrington said, "The fact that we can notice the impacts of the smoke in European skies is a reflection of the devastation of wildfires which have been burning in Canada, indicating the increased number of fires, intensity, and duration. A lot of smoke has to be generated in order for it to travel so far and be noticeable and shows how people on either side of the Atlantic are connected via the atmosphere." As we come up to the drier summer months, monitoring agencies like CAMS will continue to track these plumes across Ireland and northern Europe. See More: CAMS, Canada, Mark Parrington, Wilfire

This spring was the warmest in Ireland since modern records began
Met Éireann Met Éireann SPRING 2025 WAS the warmest spring Ireland has ever experienced in the 126 years of weather records held by Met Éireann. Of the top five average temperatures for spring (which covers March, April and May) in those 126 years, four have occurred since 2017 – signalling a pattern of rising seasonal temperatures in line with climate change. This year's spring was the first one that was more than two degrees Celsius hotter on average than the average spring temperature of the 20th century. Met Éireann's new seasonal climate statement says it was also the sunniest spring on record. Advertisement Most weather stations around the country recorded their highest values for total hours of sunshine in spring. It was a relatively dry spring, provisionally ranking as the 16th driest since the start of the relevant records in 1941 and the driest since 2020. Shifting weather patterns around the world and successive record-breaking conditions are evidence of climate change, which is being caused by human activities leading to excessive greenhouse gas emissions that trap heat inside the atmosphere. Many people will have enjoyed the unusually warm conditions this early in the year – but it's also a concerning signal of the climate change the world faces, which is on track to escalate in coming years if countries fail to reduce their greenhouse gas emissions. The unusual conditions during this spring caused a marine heatwave in Irish waters and drought conditions in numerous parts of the country. The marine heatwave develop off the west coast in April and May. Sea surface temperatures reached over two degrees warmer than average in some coastal areas and up to four degrees warmer than average in offshore areas. Related Reads Storm warning: Extreme wind is now 'priority' climate risk for Ireland Ireland's excessive emissions mean climate goals 'are increasingly out of reach' UN says 70% chance average global warming will exceed 1.5C benchmark in next five years These kinds of marine heatwaves can have major ecological impacts, according to Met Éireann, including coral bleaching, shifts in marine species, harmful algal blooms and disruptions to food chains. On land, there were numerous instances of what Met Éireann terms 'climatological dry periods' during spring 2025. These are classified as dry spells (a period of 15 or more consecutive days with no days having 1mm or more of precipitation', an absolute drought (a period of 15 or more consecutive days with no days having 0.2 mm or more of precipitation), or a partial drought (a period of at least 29 consecutive days, the mean daily rainfall of which does not exceed 0.2 mm). The areas around 11 of Ireland's weather stations had absolute droughts during spring 2025. Three had partial droughts and 22 had dry spells. Eight had two dry periods at different times during the season. Readers like you are keeping these stories free for everyone...

Canadian wildfires smoke reaches Ireland after crossing Atlantic
Forecasts show further smoke is set to reach Europe later this week. Other plumes of smoke have also gone as far as the Arctic. Smoke rises from wildfires in Flin Flon, Manitoba, Canada. Photo: Government of Manitoba/Handout/Anadolu via Getty Images Smoke from wildfires in Canada has crossed the Atlantic to reach Ireland, according to European Union researchers. Analysis from the EU's Copernicus Atmosphere Monitoring System (CAMS) has shown smoke originating from wildfires in the Canadian provinces of Manitoba, Saskatchewan and Ontario has made its way across the Atlantic and reached Europe in recent days. Forecasts show further smoke is set to reach Europe later this week. Smoke initially made its way across the Mediterranean on May 18 and 19, and there were reports of smoke in Greece and the region around the eastern Mediterranean. Smoke rises from wildfires in Flin Flon, Manitoba, Canada. Photo: Government of Manitoba/Handout/Anadolu via Getty Images News in 90 Seconds - 3rd June 2025 A second, larger plume of smoke crossed the Atlantic in the last week of May and arrived in parts of northwestern Europe, including Ireland, on Sunday, June 1. Additional plumes of smoke are expected to reach Europe in the coming days. 'Wildfires are a frequent occurrence in boreal forests from spring and through the summer months,' CAMS senior scientist, Mark Parrington, said. 'Up to the beginning of June, our data is showing that central regions of Canada have experienced a very intense few weeks in terms of wildfire emissions. 'This data, and the fact that we are able to observe the smoke in Europe, is a reflection of the scale of the fires and impacts they have been having in Manitoba and Saskatchewan. 'In CAMS we monitor events such as these in order to understand how they affect the atmosphere and air quality regionally and globally.' CAMS forecasts show the transport of smoke is not expected to have 'a significant impact on surface air quality' as the smoke is moving at a high altitude. Typically, the effects include hazy skies and red or orange sunsets. Air quality in Canada has been affected by smoke emitting from wildfires across Manitoba, Saskatchewan and Ontario and there was a 'significant increase' in both the number and intensity of the wildfires in Canada last month. More than 25,000 people in the impacted areas of Canada have evacuated their homes due to the wildfires, while US states along the border with Canada have also been affected. A state of emergency has been declared in both Saskatchewan and Manitoba for the next month. There are also wildfires burning in parts of far eastern Russia since the beginning of April, most notably in the Republic of Buryatia and Zabaykalsky Krai near the borders with China and Mongolia. CAMS said carbon emissions in Russia's Far Eastern Federal District are at the highest level for this period of time since 2018. The wildfires in Russia have also impacted some areas further afield, with forecasts showing a transport of smoke from Russia towards northeastern China and northern Japan, impacting air quality in those regions. Other plumes of smoke have also gone as far as the Arctic.
