What Will The Average Temperature Be In 2050 – The climate in Barcelona (right) is not always good – the city suffered a severe drought in 2008.

By 2050, London could be as hot as Barcelona, ​​Edinburgh could have the climate of Paris, Leeds like Melbourne and Cardiff like Montevideo.

What Will The Average Temperature Be In 2050

It comes as a study shows how a 2C temperature rise could change 520 of the world’s major cities.

Crowther Lab says more than a fifth of people in cities including Singapore and Kuala Lumpur will experience conditions not previously seen in major cities.

London could face a severe drought like the one that hit Barcelona in 2008 – when it was forced to import drinking water from France at a cost of £20 million.

The 2C rise by 2050 is compared to temperatures today in the “pre-industrial period” – generally considered to be between 1850 and 1900 – when the burning of fossil fuels had not yet caused any change to the climate.

The increase in temperatures will result in the average high summer temperature in the UK rising by almost six degrees to 27 degrees Celsius.

Scientists hope that connecting cities will help people visualize the impact of climate change over their lifetimes.

“History has shown us time and again that data and facts alone do not motivate people to change their beliefs or act,” said lead author Jean-François Bastin.

The study, published in the journal PLoS One, shows that Europe’s summers and winters will become warmer, with average increases of 3.5C and 4.7C respectively.

This is equivalent to a city moving 620 miles (1,000 km) south – the cities furthest from the equator being most affected.

Climate Change, The Un’s Warning: A Change Of Direction By 2050

The Intergovernmental Panel on Climate Change (IPCC) says global temperatures have already risen 1C above pre-industrial levels.

And at the current rate of warming – 0.2C per decade – global warming will reach 1.5C between 2030 and 2052.

People say it can be like experiencing four seasons in one day in Melbourne – people in Leeds can get used to it

The UN body has warned that more than 1.5C of warming will push us into a “very uncertain world” – adding that “current global commitments are not enough to prevent temperature rises above 2C, let alone 1.5C.” Just leave it.”

Under current national commitments, the average temperature rise by 2100 is projected to range from 2.9C to 3.4C.

The panel says we need to cut carbon emissions by 45% by 2030 to keep below 1.5C and reach net zero by 2050.

So the projections from this study are actually quite optimistic, envisioning a future where measures are taken to reduce greenhouse gas emissions.

The report estimates that three-quarters of the world’s largest cities would experience dramatic climate change under those circumstances.

Professor Richard Bates, from the Met Office Hadley Centre, said: “This study helps to put climate change into the context of human experience – and more importantly, shows that many places will see entirely new climates that are different from current human experience. is beyond.” who commented on the study.

“It seems like bringing the climate of Barcelona to London might be a good thing – if you don’t suffer from asthma or heart disease, that is – except that London’s soil shrinks and if it gets too dry So it becomes brittle, then when dried too much it swells and spreads when wet.

Europe has already seen extremes this summer, with parts of Britain receiving two months’ worth of rain in a single day, making a heat wave five times more likely to occur due to climate change.

Professor Gabby Hegerl of the University of Edinburgh said the study “does not account for individual events such as unprecedented heat waves, droughts and heavy rainfall or floods”.

It’s not good news – but it’s important not to be overwhelmed by the scale of the climate crisis.

And if you’re a little worried about the future, here are some tips on how to be a little more eco-friendly in your everyday life. Unless our billions of tons of annual emissions are significantly reduced, the concentration of greenhouse gases in the atmosphere will continue to increase. Increased concentrations are expected:

What Will The Average Temperature Be In 2050

Many greenhouse gases persist in the atmosphere for long periods of time. As a result, even if emissions stop increasing, greenhouse gas concentrations in the atmosphere will continue to increase and remain high for hundreds of years. Furthermore, if we were to stabilize the concentrations and composition of today’s atmosphere (which would require dramatic reductions in current greenhouse gas emissions), surface air temperatures would continue to warm. This is because the oceans, which store heat, take decades to fully respond to high concentrations of greenhouse gases. The response of the oceans to higher concentrations of greenhouse gases and higher temperatures will continue to influence climate over the next few decades to hundreds of years.[2]

Because it is difficult to predict far-future emissions and other human factors affecting climate, scientists use a number of scenarios using different assumptions about future economic, social, technological, and environmental conditions.

The figure shows projected greenhouse gas concentrations for four different emissions pathways. The mainstream believes that greenhouse gas emissions will continue to increase throughout this century. The lower path assumes emissions peak between 2010 and 2020 and decline thereafter.

We have already seen global warming in the last few decades. Further changes in temperature are expected in the future. Climate models predict the following major changes in temperature.

Global And European Temperatures

Projected changes in global average temperature under four emissions pathways (rows) for three different time periods (columns). Temperature changes are compared to the average for 1986–2005. These pathways are from the IPCC’s Fifth Assessment Report: RCP2.6 is a very low emissions pathway, RCP4.5 is a moderate emissions pathway, RCP6.0 is a moderately high emissions pathway, and RCP8.5 is a high emissions pathway ( Emissions) are believed to continue to increase during the century).

Changes in global average temperature under four emissions trajectories were observed and estimated. The vertical bars on the right show possible temperature ranges by the end of the century, while the lines show average projections for a range of climate models.

There is also a possibility of change in rainfall and storm patterns, including rain and snowfall. However, some of these changes are less certain than temperature-related changes. Projections show that future changes in rainfall and storm surge will vary by season and region. Some areas may see less rainfall, some more, and some may see little or no change. Rainfall amounts are expected to increase over most areas during heavy rainfall, while the storm’s path is projected to shift poleward. [2] Climate models project the following changes in precipitation and storms.

Predicted Changes In Variation Of Annual Rainfall, Length Of Growing Period, And Temperature By 2050

Projected changes in global annual mean precipitation for a low emissions scenario (left) and a high emissions scenario (right). Blue and green areas are projected to experience an increase in precipitation by the end of the century, while yellow and gray areas are projected to experience a decrease.

Maps show projected future changes in precipitation over the end of this century, compared to 1970–1999, under the high emissions scenario. For example, in winter and spring, climate models agree that northern regions of the United States are likely to be wetter and southern regions drier. There is less confidence in where the transition between wet and dry areas will occur. Confidence in the projected changes is highest in the areas marked with diagonal lines. Changes in white areas are not predicted to be greater than what would be expected from natural variability. Source: US National Climate Assessment, 2014. Click on image for larger version.

Arctic sea ice is already declining. [2] The area of ​​ice cover in the Northern Hemisphere has declined since the 1970s. [2] Permafrost temperatures [2] have increased in Alaska and much of the Arctic over the past century. . [1] To learn more about recent changes in snow and ice, visit the Snow and Ice page in the Indicators section.

Over the next century, sea ice is expected to continue to decline, glaciers will continue to shrink, snowpack will continue to shrink, and permafrost will continue to melt. Possible changes to ice, snow, and permafrost are described below. These maps show the projected loss of sea ice in the Arctic and Antarctic. The maps under a) show average ice density (relative area covered by sea ice) over 1986–2005. Maps in b) and c) show climate model simulations of sea ice thickness in February and September under low (b) and high (c) emissions scenarios at the end of the 21st century. In
