2018: a year in global climate statistics

2018 was a significant year for the monitoring of the climate, as reported in the latest State of the Climate report, published by the Bulletin of the American Meteorological Society.

One of the highlights is that globally, 2018 was the fourth warmest year in a record stretching back to the mid-1800s. Combined with the previous three years, the last 4 years were the warmest in the record, with 2016 being the warmest in the instrumental record. The report also highlights that every year since 2000 annual global surface temperatures have been above the 1981-2010 long-term average.

In both scope and production, the State of the Climate report series is global. Over 165 authors from around the world help compile the chapter on the Global Climate, including six from the Met Office. The latest State of the Climate report is the 29th edition.

Robert Dunn is a Met Office senior scientist who also leads the editorial team for the Global Climate chapter. Commenting on the latest report covering 2018, he said: “One of the stories that the BAMS State of the Climate draws out is that the number of warm extreme temperatures is much larger compared with the number of cool extremes. For example during the heatwaves experienced last year, new maximum temperature records were set in Japan, Canada and Algeria.

“However, although the number of cool extremes was much lower, they still occur. Notably, during the period when the “Beast from the East” drove a period of intense cold air from Siberia, the UK recorded a new low daily maximum temperature for Spring with a daily maximum of -4.7 C recorded in Tredegar in Wales. There were also cool autumn records in the eastern United States.”

Other sections of the report focus on the water cycle, land surface and atmosphere. Of particular note are the latest reports on the cryosphere – the Earth’s combined natural resource of frozen water, above and below the surface.

Regular monitoring of the mass of specific glaciers descending down mountain valleys – so-called alpine glaciers – reveals that the loss of ice during the period 1980-2018 was equivalent to the removal of a 24-metre slice of ice from the top surface of an average alpine glacier.

Robert Dunn added: “The rate of loss of volume from alpine glaciers during 2018 has been so extensive that it may surpass the rate in 2003, the previous record year. Glaciers have lost mass in every year for the last 30 years.”

Carbon dioxide levels reached 408.5 ppm at Mauna Loa in 2018, compared with 315ppm when monitoring started in 1958.  When looking at the concentration of greenhouse gases, including carbon-dioxide, methane and nitrous oxide, their combined forcing in 2018 is 1.43 times greater than the figure in 1990.

After a peak in 2016, the global area in drought has declined slowly to reach below average levels. During 2018 around one fifth of the earth’s land surface was considered in moderate drought and 2.7 % in extreme drought.

Here are some of the numbers from 2018:

3.1 mm—the mean annual global rise in sea level in the satellite era—a trend that is accelerating.

11: The worldwide count of Category 5 tropical cyclones, one off the record set in 1997.

22%…the portion of anthropogenic carbon releases in 2008-2017 absorbed by the oceans, moderating the atmospheric warming but acidifying waters.

24 meters: the thickness that would have had to be lopped off the top of the world’s glaciers to equal the mass of ice lost since 1980.

30 years: the ongoing streak in which global glacier mass has decreased.

51.3°C: new national record for Algeria set at Ouargla on 5 July.

77%: the portion of Arctic ice pack in March 2018 that was first year ice—highly vulnerable to summer melt.

81 mm: the amount global annual mean sea level exceeded the 1993 level.

1262 mm: A U.S. record for 24-hr rainfall in Waipā Gardens (Kauai), Hawaii, 14-15 April.

500 million hectares: the lowest global fire extent area since records began in 1997.

$40 billion: The combined cost of U.S. wildfires in 2017 and 2018.

These key findings and others are available from the State of the Climate in 2018 report released online today and can be read in full here.

Wet June comes to a hot conclusion

With a warm end to the month and notable rainfall, you may be forgiven for thinking that June 2019 would automatically be a record-breaking month. In reality, the month as a whole might not beat previous Junes for heat or overall rainfall, but it will be remembered for some extreme weather events.

Notably, Lincolnshire received 230% of the rainfall expected in June, compared with the average between 1981-2010. Wainfleet in Lincolnshire recorded the highest daily rainfall total of any UK station with 74.6 mm of rain on 10 June.

Across Lincolnshire, the rainfall wasn’t sufficient to break the June county rainfall record of 181.9 mm in 2007, but with 128.9 mm it was in fourth place in a series stretching back to 1910. New records were set for two-day and three-day total rainfall in Lincolnshire on 10-11 and 10-12 June respectively; both previous records were set in July 1968.

Flintshire in North Wales was the wettest county when compared with average; and here it was the second wettest June since 1910. The rainfall was largely due to the presence of persistent areas of low pressure which had become anchored over parts of the UK, sitting in the loop created by the buckling of the jet stream – known to meteorologists as an Omega block.

June Rainfall map

When reviewing temperatures, June 2019 was a remarkably average month. The mean temperature for the UK was only 0.2 °C above the long-term average. One of the regions to deviate the most from this was East Anglia, with both Norfolk and Suffolk average temperatures being 1.1 °C above the long-term average: 14.5 and 14.7 °C, respectively.

Much of the month had been notably cooler than average, but towards the end of the month an area of significantly warm air moved northwards across Europe bringing record breaking temperatures to France, Germany, Poland and the Czech Republic. Although temperatures were not record breaking in the UK, several days of high temperatures were recorded across the country with some individual locations reaching heatwave thresholds. The window of heat shifted from west to east culminating in the highest maximum temperature of 34.0 °C at Heathrow and Northolt on 29 June. By contrast, the lowest minimum temperature was -0.3 °C at Redesdale Camp in Northumberland on 10 June.

There was also lower than average sunshine hours for many parts of the UK, with only Scotland and Northern Ireland receiving more than the long-term 1981-2010 average. The sunniest location was the Isle of Man with 236.5 hours of sunshine.

Preparing for when the sun wakes up

Written by Mark Gibbs, Head of Met Office Space Weather Operations Centre and Dr Mario Bisi, Space Weather Scientist, STFC RAL Space

Experts from across the globe are in the UK this week discussing plans for a new European space mission aimed at improving our space weather forecasting capability.

Discussions will focus on plans to replace the spacecraft at Langrage 1 (L1) and Lagrange 5 (L5) locations. These proposed new spacecrafts are critical if we are not only to maintain our forecast skill but also enhance our ability to forecast damaging space-weather events with newer instruments and a more secure data supply.

The ‘Preparing for when the sun wakes up’ workshop brings together the key scientific/technical experts, science advisors, governments and service providers necessary to ensure international preparedness for future space-weather forecasting capability.

This workshop, the 3rd hosted by the UK, has special significance as it will be the last ‘rallying call’ ahead of the European Space Agency (ESA) Council of Ministers meeting in December where ESA will be asking member states to provide the funding to begin building the L5 spacecraft ready for launch in 2026.

 

During the two-day event (27 & 28 June 2019) around 85 participants, predominantly from Europe and the USA, will examine the progress of the two ESA mission studies, the designs of the instruments that will fly into deep space and how these spacecraft support the global effort to mitigate the impacts of space weather.

Forecasters have already glimpsed the benefit that a L5 mission will give, from the NASA Solar TERestrial RElations Observatory (STEREO) mission. The two STEREO spacecraft have spent the last decade slowly making a partial orbit of the Sun providing new viewpoints of it and of the intervening space between the Sun and the Earth.

The USA is planning a mission, complimentary to the European L5 mission, that will replace both the NASA SOlar and Heliospheric Observatory (SOHO) and Deep Space Climate ObserVatoRy (DSCOVR) spacecraft at L1. Together these two missions would future proof the current assets and provide enhanced space weather forecasting capability.

Severe Space Weather is recognised as a medium-high risk on the UK Government’s National Risk Register. The impacts of an event similar to the Carrington event of 1859 (which is likely to occur on average once a century) could include localised power blackouts, loss of GPS signals (for navigation and accurate timing), and interruption to vital satellite services, which are critical for the day-to-day services that we rely on. These impacts occur as a result of billions of tonnes of magnetised plasma that is explosively released from the Sun, known as a coronal mass ejection (CME). CME’s can head in any direction but forecasters analyse the infrequent images from SOHO and STEREO to determine the speed, size, and crucially, whether the CME is Earth directed.

The two missions to the L5 and L1 points will provide a reliable real-time flow of images and information to space-weather forecasters around the globe, both replacing and improving on the images and data from SOHO and STEREO, both of which are operating many year’s beyond their design life.

The UK has led the initiative to launch an operational mission to L5, from the early concepts through to the current design studies funded by ESA. The UK, through the UK Space Agency is the largest funder of this ESA initiative. Of the four design studies underway, three are led by UK organisations Airbus, the Science and Technology Facilities Council’s RAL Space and UCL-MSSL.

Permanent Secretaries visit Met Office HQ

As part of their visit to the South West for Civil Service Live events this week, Met Office Chief Executive Penny Endersby was delighted to host Cabinet Secretary and Head of the Civil Service Sir Mark Sedwill to our Exeter HQ along with a number of departmental Permanent Secretaries including Tamara Finkelstein (Defra), Matthew Rycroft (DFID) and Shona Dunn (Home Office).

During the visit they were shown how Met Office weather and climate science helps security and prosperity in the UK and around the world. This is especially achieved through working collaboratively not just with other departments and agencies, but also with the wider public sector, private sector and beyond.

CB5A0003

The wide-ranging work of the Met Office which supports government departments includes supporting flood risk management now and in the future, animal and plant health, UKCP18 and air quality with Defra. Further examples include helping DFID meet the challenges of climate change through in-country programmes and supporting humanitarian responses to severe weather. This wide spectrum of work was summed up by Sir Mark Sedwill who said:

“Thank you for making me and my colleagues feel so welcome during our visit, it was fascinating to see the work of the Met Office and I was really impressed with how you work across the Civil Service and the World, providing critical services to businesses and communities. Your work with other agencies and organisations across the public and private sector is an excellent example to us all in providing joined-up public services that have a positive impact on our citizens”

A cool and wet June so far after a warm start 

June 2019 got off to a false start – despite a warm first few days, the rest of the month so far has been much cooler and rather wet.

The UK has been stuck under an area of low pressure for most of the month so far, bringing a succession of slow-moving weather fronts and heavy rain.

For most days, the maximum temperature has been well below the UK June average of 17.3 Celsius, with the UK average maximum 15.5 C as of 13 June.  Temperatures across the UK were widely below average on 11 June in particular, with much of central Wales struggling to reach 10 C.

June max temp anomoly

At almost halfway through the month, England and Wales have already reached their average monthly rainfall totals for June, with 127% of the expected rainfall recorded in England and 120% in Wales.  The wettest June on record for the UK is 2012, where the country received more than double (203%) of average rainfall for the month.

Monday 10th and Tuesday 11th were particularly wet days, especially in the east and southeast England and northeast Wales, where some places recorded almost two month’s worth of rain in one day.

Flintshire in northeast Wales is the wettest region so far this month, receiving 140.5 mm (225%) of its average June rainfall.  This is followed closely by Lincolnshire, which recorded 111.2mm, or 198% of June average rainfall. .

The wettest place relative to average this month is Wainfleet (Skegness) recording nearly three times (287%) its normal June rainfall so far.

In Ham Hill, Kent, 94.6mm of rain fell within a 24-hour period – twice the June average of 47.6 mm for Kent.

The map below shows the rainfall so far this month as a percentage of the June average. The dark blue areas are those that have already received more than twice their normal June rainfall. In contrast Scotland has received just over half its normal June rainfall in the first half of the month so is much closer to what we might expect for this point in the month.

June rainfall

The Met Office issued a series of National Severe Weather Warnings for heavy rain and thunderstorms during this period, with amber rain warnings for London, southeast England and southeast Scotland. The Environment Agency issued numerous flood warnings and alerts, with significant flooding in Lincolnshire where over 100 properties were flooded and disruption to transport including railway lines.

Why the wet weather?

The unsettled weather and heavy rain is a result of an omega blocking pattern, with low pressure in the western Atlantic, high pressure in the mid-Atlantic and low pressure in the east Atlantic.  The UK has been stuck under this latter area of low pressure, allowing weather fronts to continually feed across the UK from the east.   Heavy showers and thunderstorms also developed in this set up, adding to the already high rainfall totals.

Not everywhere has been very wet however, as western parts of Northern Ireland and Scotland have been shielded from the worst of the heavy rain.

Science Camp in full swing for 2019

Met Office Science Camps have returned for their seventh year, with two camps having taken place earlier this year and two more to go.

Our Science Camps are a popular part of the Met Office STEM Outreach programme, giving 11-13 year old students the unique opportunity to camp overnight at one of the UK’s premier science and engineering organisations.

The camps typically run through spring and summer terms, with students taking part in demonstrations and activities to learn about weather and climate science, as well as finding out more about how the Met Office forecasts the weather and climate predictions.

This year saw the introduction of some new content, which was received well both by campers and volunteers.

Leader of Met Office Science Camp Core Team, Debbie O’Sullivan, said:

“Thanks to the dedication and enthusiasm of all of our volunteers we have had a great start to Science Camp 2019. The students had a fantastic time and left a lot more inspired than when they arrived.”

Science Camp pics

And here’s some of our students thoughts from Science Camps earlier this year:

‘Thank you to all at the Met Office for putting on an Amazing, Brilliant, Educational, Exciting camp’

I adored it here, all the memories I have made are irreplaceable. I love the Met Office!’

I had an amazing time learning the process of how the weather is forecasted on a daily basis and how different part of the weather are formed. I now feel more inspired to go into something to do with the weather in the future.’

The Met Office camp was great, because it taught us about a wide range of techniques and skills that would be needed for numerous weather related jobs and issues. I learnt much here and I really enjoyed it!’

The positive feedback is down to the hard work of over one hundred Met Office staff who volunteer their time for Science Camp, demonstrating their passion for what we do at the Met Office and ensuring the camps are inspiring and enjoyable.

With a fantastic start to Science Camp 2019, we look forward to continuing the camps throughout the rest of this year.

Check out our website for more information on Science Camp at the Met Office.

Unremarkable month brings Spring to a close

A very average month of May has brought Spring 2019 to a close, with temperatures, sunshine and rainfall all close to the long-term averages for the UK.

There have been regional differences though, with a clear split between north and south with varying amounts of rainfall when compared to the 1981-2010 long-term average. South-west England was comparatively dry, in sharp contrast to north-east Scotland. Moray received more than double its average monthly rainfall with 128.8 mm while further south-west Carmarthenshire only received 36% of its average with 33.6 mm of rainfall.

2019_5_Rainfall_Anomaly_1981-2010

The hours of sunshine have also been close to average across the UK, with the most sunshine in South West England and South Wales where there was 212 hours of sunshine.

2019_5_Sunshine_Anomaly_1981-2010

Mean temperatures across the UK were all close to the long-term average too, with all regions just under the average. The UK was 0.3 °C below average with a mean temperature of 10.0 °C.

2019_5_MeanTemp_Anomaly_1981-2010

Provisional May 2019 Mean temp (°C) Sunshine (hours) Rainfall (mm)

Scotland 8.3 -0.5 168.5 95 105.5 125
N Ireland 9.9 -0.3 158.5 87 58.5 81

Looking at Spring as a whole there is a broadly similar distribution of conditions. Many regions received more than their average rainfall for the season, predominantly in the north and west. Once again, Moray was the wettest county when compared to the long-term average with 45% more than average, 272.2 mm in total. Other areas saw below-average rainfall, mostly in the south and east. Bedfordshire received 87.2 mm which is 62% of its average Spring rainfall total.

2019_13_Rainfall_Anomaly_1981-2010

Despite spells of warmer weather, including over the Easter weekend, temperatures ended up being only just above average across much of the UK. For the country as a whole Spring was 0.7°C above the long-term average. The mildest location compared to its average was the Isle of Wight which was 1°C above average.

2019_13_MeanTemp_Anomaly_1981-2010

It was a sunny Spring, all regions exceeded their average sunshine hours with the exception of Northern Ireland. East Anglia was the sunniest area with 537 hours of sunshine across March, April and May.

Changing climate = a changing view of the British & Irish garden

In late February 2019, an historic climate event occurred. A flow of very warm southerly air (in conjunction with an area of high pressure) resulted in the first recorded occurrence of temperatures in excess of 20 °C during a UK winter season, reaching 21.2 °C at Kew Gardens.

This week delegates of the PlantNetwork charity’s annual conference will be gathering at Abbotsbury Subtropical Gardens to discuss the issues posed by climate change and how these will affect the nation’s gardens and designed landscapes.

The February warm spell created several issues for gardeners:

  • many garden plants emerged rapidly from their dormancy (only to be damaged by the frosts in April);
  • lawns required their first and second cuts much earlier than normal;
  • many gardeners needed to water their gardens.

Janet Manning, Water Management Specialist at the Royal Horticultural Society, said: “Twitter was scattered with tweets from gardeners who felt the need to water their gardens for the first time ever in February,”

Taro from southern Asia is a plant which may do well in the UK's warming climate

Taro (Colocasia esculenta) – a tropical root vegetable from southern Asia – might become more widespread across southern Britain in future: it already grows well at Abbotsbury Subtropical Gardens cared for by curator Stephen Griffith (pictured).

Gardens have to endure drought, heavy rainfall and extremes of temperature. The types of plants grown in gardens and how gardens are designed and managed will need to change to take into account higher temperatures and changing rainfall patterns. Key to all of this is translating the current climate projections to gardens around the country.

John Edmiston, of the nursery Tropical Britain, considers the types of plants we might be growing in a hotter, drier climate. He said: “Climate change will have a massive effect on British horticulture. Gardens will need to be more resilient to drought. The dominant style in British garden design has for many years focused on herbaceous perennials soaking up large quantities of water. As we move into a hotter drier future, many public gardens and garden designers will use more plants adapted to dry conditions, combining hardy desert species with drought-resistant perennials to create a new style. Fifty years from now, British gardens will look quite different.”

Dr Mark McCarthy is the head of the Met Office’s National Climate Information Centre. He said: “The UK climate is warming, increasing the likelihood of events such as those seen in February and last summer’s heatwave. The latest set of UK climate projections (UKCP18) show that extreme hot summers like 2018 or 1976, could be more frequent by the 2050s, and that our winters are very likely to be milder and wetter.”

Invasive potential

Introducing plants into gardens from around the world is not risk free. New pests and diseases have the potential to spread into the UK on a variety of plant material and in soils, particularly as the UK climate becomes more amenable to their survival. Tomos Jones, a PhD student at the University of Reading, has studied the invasive potential of many ornamental plants. Tomos said: “Climate change could allow more ornamentals to become invasive, as conditions become more suitable. Gardeners have an important role to play in preventing plant invasions, in their choice of plants to grow and in disposing of potentially invasive plants responsibly. Gardeners are on the ‘front line’ in identifying plants in their gardens showing ‘invasive characteristics.”

There are design challenges too. Heritage gardens often use a narrower range of plants than we now have available, but a changing climate might mean that these gardens and landscapes will need to find plants better able to survive rather than being true to the period of the garden. Water and soil management are crucial factors in horticulture and are vital in a changing climate.

Everyone can make a difference. But those small changes can really add up to a significant impact. As Janet Manning, added: “If the 27 million gardeners in the UK could save just one watering can full of mains tap water this summer, we would have saved enough water to supply Bristol, Leeds and Sheffield for a whole day, that’s significant and achievable.”

Simon Toomer, PlantNetwork Chair, said: “Now is the time for horticulture – an industry worth £24bn to the UK economy – to step forward and be part of the solution:, planting a tree is still one of the quickest, simplest and cheapest ways to remove carbon from the atmosphere.”

  • PlantNetwork is a charity supporting gardens, arboreta and other plant collections through training, networking and information exchange between gardens. This year’s major topic at the annual conference is “Climate Change and Gardens”, professional gardeners from across Britain and Ireland will discuss how the sector can be better prepared for a changing climate.

A varied April comes to a warm conclusion

April 2019 will be remembered for a combination of both cold and very warm conditions; the latest statistics show that the warmer spells boosted UK mean temperatures to provisionally 1°C above the long-term average when looking at the month as a whole.

After a cold, and in some places wet, start to the month, many will remember the exceptionally warm and sunny weather across the UK over the Easter weekend. A number of records were broken including it being the hottest Easter Monday on record in England, Northern Ireland, Scotland and Wales. Over the Easter weekend a total of 18 weather stations across the UK broke their April temperature records.

The Isle of Wight was the area with the highest average temperature, 10.2°C, with Middlesex, Cornwall and Anglesey closely following. The highest temperature recorded was 25.8°C at Treknow in Cornwall on 19th April. Scotland was also notably warm when compared to the long-term 1981-2010 average with mean temperatures 1.4°C higher for the month.

2019_4_MeanTemp_Anomaly_1981-2010

Map shows April 2019 mean temperature as a percentage of the 1981-2010 climatological average

Overall it was a relatively dry month with only Wales and Northern Ireland reaching average rainfall totals. England has seen particularly low levels of rainfall, especially in the east. East Anglia has received just 25% of its average monthly rainfall. The former county of Huntingdonshire was the driest county, with just 9.5mm of rain through the whole of April.

As well as being a dry month, April was a particularly sunny month too. The UK saw 14% more sunshine hours than average with only Northern Ireland receiving below average sunshine with 87% of the long-term average. East Anglia was also the sunniest region with 191.2 hours of sunshine, 19% more than the long-term average.
