    Here’s what the average temperature in your city could be without major emission cuts – Nashville-Davidson, Tennessee

    (NEXSTAR) – World leaders should meet in Scotland this month for the 26th United Nations Climate Change Conference (COP26 for short) to take steps to deal with climate change and avoid the most tragic scenarios. Discuss actions. Predictions from Climate Central scientists give us an idea of ​​what the future would look like if key actions were taken, and what would happen if they weren’t.

    Climate Central is an organization of scientists and journalists focused on studying the effects of climate change and rising global temperatures. The group’s latest projects represent two futures in the United States. One has significantly reduced global emissions and the other has not.

    The map above shows that the effects of global warming are not equally felt across the country. By 2100, average temperatures are projected to rise most dramatically in the Upper Midwest and parts of New England.

    (Note that temperature changes on the map are shown in degrees Celsius. A 2 degree Celsius rise is about 3.6 degrees Fahrenheit. A 6 degrees Celsius rise (the darkest shade of purple on the map) is about 3.6 degrees Fahrenheit. It is 10.8 degrees.)

    Scientists also made local forecasts for 200 US cities (see some forecasts below, and details at the bottom of this story).

    In these graphs, you can see the range of possibilities for two different scenarios. One is a scenario that significantly reduces global emissions, and the other is a scenario that follows much the same path as it is today. The model only sees the average annual temperature and does not capture the maximum and minimum temperatures, but these drastic fluctuations are also there.

    “We know that the average temperature is rising, which means that extreme temperatures are rising disproportionately,” says Sean Sablet. “Warming things a little increases the energy in the atmosphere, increases record highs, increases precipitation, and makes things dry a little faster, which makes drought worse.”

    When looking at average annual temperature figures, Sublette encourages you to think about everything that accompanies that rise.

    Taking Los Angeles as an example, continuing the current pace of emissions predicts an average annual temperature in the late 1970s by 2100. 72 degrees Fahrenheit seems to be a comfortable temperature. But that’s not what you think of it, Sabrette says. This is about 5 degrees warmer than the current average.

    “You have to think that every lonely day is five degrees warmer than before,” says Sublette.

    Those consistently hot and dry days have a big impact. It depends on where you are in the country.

    “If you’re on the shore, rising sea levels is a huge problem,” Sabrette said. “In the western part of the Rocky Mountains, the desert climate gets even hotter, especially when affected by the heat of the city. Thirty years later, Phoenix has many days of staying between 10 am and 2 pm. It may be 124 degrees. If you start to reach 120 on a regular basis, you will have problems with your infrastructure. The pavement will melt and you will not be able to fly. This will happen. AC power demand says Not even.

    “Things dry faster, so droughts make things worse … and if it doesn’t snow that much in winter, there’s no snow that can be pulled in spring. Summer to irrigate crops. How many in the Central Valley Do you know if your vegetables are grown? ”(Drought: There are many. About a quarter of the country’s food comes from Central Valley of California, According to the USGS. )

    “East of the Rocky Mountains, it’s a humider climate,” Sublette continued. “So it will be hard for people to cool themselves. Boston will feel like Charleston, South Carolina. Washington DC will start to look like Jacksonville, Florida. St. Louis will be like New Orleans. And Twin Cities will be like St. Louis. “

    Sablet predicts that crops will need to grow further north and mosquitoes will thrive.

    However, he says, these results are inevitable, as shown in the second row of the graph labeled “Significant reductions”. What exactly does that mean? Sublette admits that this is a large-scale business, but basically it will aggressively reduce carbon emissions and rapidly expand the use of renewable energy.

    COP26, where world leaders are discussing plans to reduce greenhouse gas emissions, will be held in Glasgow, Scotland, until November 12. To date, more than 100 countries have promised to significantly reduce methane emissions. India has also promised significant emission reductions in the short term and has set a goal of zero net emissions by 2070. More than 20 countries, including Ukraine, Vietnam, South Korea, Indonesia and Chile, have pledged new cuts. Coal use (all different timelines).
