The world’s temperature has reached an average exceeding 1.0 °C above pre-industrial levels for the past two decades: the first time that a 20-year period has reached this threshold since records began in 1850.

that the temperature trend remains upward. The fact that the 20-year average has reached more than 1.0 °C above pre-industrial levels will focus the minds of delegates at COP26 aspiring to keep global temperature rise to within the limits agreed in Paris six years ago.” The global mean temperature for 2021

What kinds of things do scientists predict will happen in the UK as a result of climate change? • yAverage temperatures in the UK will continue

complex. While there is not clear evidence that climate change is increasing or decreasing the frequency of these storms, there is strong evidence that increasing sea temperatures increase the intensity of tropical storms when they develop. Heavier rainfall is also expected as global temperatures rise

. With the expected continued warming of the eastern tropical Pacific because of the emerging El Niño, it is likely that global sea-surface temperatures will challenge more records this year. When you look at regional examples, the picture becomes even more stark. The temperature rise in the North Atlantic

Overshoot likely needed to keep to 1.5°C rise by end of century Author: Press Office 5 April 2022 Could the world still be on track to keep global temperature rise to 1.5C above pre-industrial levels by the end of this century? Yes, with ambition it could be. But, increasingly, this almost certainly

becomes ice-free in summer at some point this century, will depend on the scenario of future greenhouse gas emissions and resulting rate of warming. Under a low emissions scenario – consistent with keeping global temperature rise to below 2°C above preindustrial levels – some sea ice is projected

in its lower layers. This happens through evaporation of water from the sea surface. An air mass with a long land or continental track will remain dry. Air mass becomes comparatively moister at low levels from ocean evaporation Air mass remains dry moving over land Ocean surface Land surface Figure 2

, specifically at the 300 hPa pressure level, which is around 30,000 feet above sea level. This level is often used to analyse the jet stream, but this week we’re focusing on temperature patterns at that altitude. A pool of cold air is forecast to move from Iceland into Ireland and then into southwest England

There is more than a 40% chance that the annual average global temperature in at least one of the next five years will temporarily reach 1.5°C above pre-industrial levels.

already be seen in the next few years.” The Paris Agreement seeks to keep global temperature rise this century well below 2.0°C degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5°C. The update also identifies the 90% likelihood

temperatures continue to rise this week, with plenty of warm, dry and sunny weather expected across the UK over the Bank Holiday weekend. Met Office Chief Meteorologist, Frank Saunders, said: "We’ve already seen higher than average temperatures this week, with 19.4 Celsius reached yesterday (Wednesday 17th
