New study links global warming and air pollution

A new study by an international team of researchers, including scientists from King’s, shows that implementing 14 key air pollution control measures could slow the pace of global warming, save millions of lives and boost agricultural production.

The research identifies 14 measures targeting methane and black carbon emissions that could slow global mean warming by approximately 0.5ºC by 2050. The measures could also prevent between 700,000 and 4.7 million premature deaths each year and increase global crop yields by between 30 million and 135 million tonnes per season.

New Daily Air Quality Index update

As the last of the fireworks died away in the early hours of 1st January, revised web pages and apps were launched by King’s College London to report to the new national daily air quality index that came in to force at the start of the New Year.

Changes to the index were far reaching, with updates to the break points between the banding levels, measurement periods and reported pollutants; notably the inclusion of PM2.5 in to the index.

Valid from         12:00 Friday 10^th February 2012

Valid until:         12:00 Monday 13^th February 2012

Current air pollution

‘Moderate’ nitrogen dioxide is currently being recorded at Kensington and Chelsea – Earl’s Court Road.

PM₁₀ particulate at the Ealing 8 monitoring site on Horn Lane, Acton is currently predicted to be ‘low’ today. The site is affected by specific local sources of PM₁₀ particulate and it is not representative of other areas within the Borough. The Ealing 8 measurement site forms part of an investigation of the local PM₁₀ sources at this location.

Current air pollution

‘Moderate’ nitrogen dioxide is currently being recorded adjacent the King’s Road in Chelsea and in Putney High Street.

Forecast

Elevated nitrogen dioxide and particulate pollution has been occurring for much of the week and will continue into the first part of the weekend as still, calm weather conditions persist with addition of pollutants arriving from north-eastern Europe.

There is a 60% chance of ‘moderate’ PM_10­ occurring at roadside sites and 40% chance of ‘moderate’ PM_2.5. There is a reduced (10%) chance of ‘moderate’ nitrogen dioxide due to lower local emissions during the weekend.

Pollution levels are likely to be lower into the second half of the weekend as the weather is forecast to start to change to slightly more unsettled conditions and influx of pollution from the continent is not expected.

Air pollution is expected to remain ‘low’ in your area for the following pollutants throughout the forecast period:

Ozone

Sulphur dioxide

This forecast is intended to provide information on predicted pollution levels across your borough where significant public exposure may reasonably be expected. It may not apply in very specific areas close to unusually strong or short-lived local sources of pollution

Current air pollution

‘Moderate’ nitrogen dioxide is currently being recorded adjacent the King’s Road in Chelsea and in Putney High Street.

Forecast

Relatively calm weather is hindering dispersion of traffic pollution from London. Additionally airborne particles from continental sources are expected to increase over the next 24 to 36 hours. The combination of these pollutant sources will lead to a 50% chance of ‘moderate’ PM₁₀, PM2.5 and NO2 close to busy roads, especially into tomorrow. There is a slight (25%) chance of moderate PM2.5 and PM₁₀ at background locations.

Early cloud will clear with cold clear conditions expected in all areas throughout the afternoon. It will remain clear and feeling very cold for much of the night with a widespread frost forming. Patchy cloud may bring some light snow flurries later on continuing into Wednesday morning.

The calm weather conditions with poor pollutant dispersal will bring an 80% chance of ‘moderate’ PM₁₀ and PM_2.5 pollution occurring at roadside locations during the forecast period.

There is a 60% chance of ‘moderate’ nitrogen dioxide occurring at busy roadside locations during the rush hour tonight and again tomorrow morning.

The site is of particular interest since it was the first monitoring site specifically opened by a local authority to monitor particulate in the vicinity of a waste management site and has exceeded the Air Quality Daily Objective for PM10 every year since it opened in 1999.

Forecast

Continuing cold, calm conditions this afternoon and over the weekend will cause elevated pollution levels. This, coupled with a shift to more easterly winds, may (25% chance) lead to ‘moderate’ PM₁₀ pollution being recorded in roadside locations during the forecast period.

Current air pollution

Air pollution is currently ‘low’ in your area.

Although the current air feed remains from across north central Europe it is now from a much higher altitude than earlier in the week and is therefore collecting less pollution on the way.

PM₁₀ particulate at the Ealing 8 monitoring site on Horn Lane, Acton is currently predicted to be ‘low’ today. The site is affected by specific local sources of PM₁₀ particulate and it is not representative of other areas within the Borough. The Ealing 8 measurement site forms part of an investigation of the local PM₁₀ sources at this location.

Forecast

Conditions tomorrow are expected to remain the same as today except that winds will ease this evening.  This will reduce the dispersion of local emissions.

There is a 10% chance of ‘moderate’ nitrogen dioxide at busy roadside locations during the rush hour tonight rising to 40% tomorrow morning.  PM₁₀ Particulate levels will also rise tomorrow morning.

Air pollution is expected to remain ‘low’ in your area for the following pollutants throughout the forecast period:

Current air pollution

Air pollution is currently ‘low’ in your area.

Widespread ‘moderate’ PM₁₀ and PM_2.5 has been measured across London and south-east England yesterday and a small number of sites reached the ‘high’ banding.

PM₁₀ particulate at the Ealing 8 monitoring site on Horn Lane, Acton is currently predicted to be ‘low’ today. The site is affected by specific local sources of PM₁₀ particulate and it is not representative of other areas within the Borough. The Ealing 8 measurement site forms part of an investigation of the local PM₁₀ sources at this location.

Forecast

Particulate levels remain elevated this morning as an easterly airflow continues to bring pollution from continental Europe to combine with emissions from local traffic. ‘Moderate’ PM₁₀ and PM_2.5 are expected close to busy roads again today with a 20% chance in background locations.

Nitrogen dioxide levels have dropped in the last couple of days as wind speeds increased. There is a 10% chance of ‘moderate’ nitrogen dioxide at busy roadside locations during the rush hour tonight and tomorrow morning.

Air pollution is expected to remain ‘low’ in your area for the following pollutants throughout the forecast period:

Ozone

Sulphur dioxide

This forecast is intended to provide information on predicted pollution levels across your borough where significant public exposure may reasonably be expected. It may not apply in very specific areas close to unusually strong or short-lived local sources of pollution.

Outlook

Cold conditions and a polluted easterly air flow are expected to lead to elevated and ‘moderate’ PM₁₀  and PM_2.5 for the remainder of the working week.
