T.Climate crisis means that summer is a time of increasingly dangerous heat. Temperatures in the Pacific Northwest this week are not just breaking, they are breaking. Temperatures in British Columbia, Canada, reached a staggering 47.9 degrees Celsius. Dozens of people have died from heat stress along the “roads” amid temperatures commonly found in the Sahara Desert. Buckling and melt power cables“
Earlier in June, another heatwave Seen Five Middle Eastern countries are at the top at 50 ° C. Extreme heat reached Pakistan, where 20 children One class reported falling unconscious and needed hospital treatment for heat stress. Thankfully, they all survived.
Excessive heat from greenhouse gas emissions means that such heat waves are more likely, and scientists can now calculate an increase in their potential. For example, 2019 European heatwave Killed There were 2500 people Five times More likely, without global warming.
In most places, extreme heat waves, beyond the normal range for a region, can range from disrupting the economy to causing massive deaths, especially among young and old alike. Nevertheless, in the Middle East and Asia, a truly dire situation is emerging: the creation of unheated heat.
While a person can survive temperatures above 50C when the humidity is low, when both the temperature and humidity are high, neither sweating nor cooling ourselves can cool us down. What’s the difference? The temperature of a “wet bulb” – given by a thermometer covered in a wet cloth – indicates the temperature at which sweat or water evaporates. Humans cannot escape the temperature of a wet bulb longer than 35 centimeters because there is no way to cool our body. Not even in the shade, and not even with infinite water.
35C wet bulb temperature was once considered impossible. But last year scientists Reported That places in the Persian Gulf and Pakistan’s Indus Valley have already reached this threshold, albeit only for an hour or two, and only in small areas. As climate change raises temperatures, heat waves and accompanying invincible temperatures are predicted to hit some areas, including Africa and the Southeast of the Americas, in the coming decades, and It is likely to be found in new areas, including Africa and the southeast of the United States.
What can governments, companies and citizens do? First, cut off carbon dioxide emissions by half this decade and cut off the supply of far more intense heatwaves, and then reach zero emissions by 2050.
Second, prepare for the inevitable heatwave of the future. Public health emergency planning is a top priority: getting people the information they need and moving vulnerable people to air-conditioned areas. Heatwave forecasts should include wet bulb temperatures so that people learn to understand the dangers.
Plans should take into account the fact that heatwaves increase structural inequality. Green spaces are generally fewer and warmer in poorer neighborhoods, while outsourced workers, who are often paid, are particularly vulnerable. Once the heatwave is over, rich people can buy cooling equipment at a higher price and have many more options to escape, highlighting the importance of public health planning.
In addition to tackling crises, governments need to invest in making countries work in the new climate we are creating. In terms of climate policy, this is known as “adaptation”.
The top priority is for energy supply as heatwaves are flexible, as people will rely on electricity to cool off air conditioning units, fans and freezers, which are life-saving in heatwaves. Similarly, Internet communications and data centers need to be proof in the future, as they are essential services that can struggle in the heat.
In addition, new regulations are needed to keep buildings cool and to enable the transport system, from roads to trains, to operate in extreme temperatures.
Many of these changes can meet other challenges. Homes with retro fittings are also the best place to modify them to keep us cool. For example, installing electric heat pumps in warm homes in the winter means that in the summer they can also be switched to run in reverse to act as a cooling system. Cities can be kept cool with green roofs and mostly green spaces, which also makes them better places to live.
The final task is the future of agriculture and the wider ecosystem on which we ultimately depend. Heat can wreak havoc with crop production. In April this year, it was only two days hot in Bangladesh destroy The 68,000 hectares of rice affect more than 300,000 farmers at a loss of US 39 39 million (US 28 28 million). New types of heat tolerant crops need to be developed and developed. Alternatives to this are rising food prices and rising food prices with poverty and urban unrest that are usually with them.
Given these enormous challenges, how are governments working to adapt to climate change? Under the Paris Agreement on Climate Change, countries are forced to submit adaptation plans, but only 13 countries have done so. One of them is the UK, but the government had plans decided Through its own independent advisers, it “failed to keep up with the growing reality of climate change.”
The Glasgow Cup 26 climate talks will need to shed light on adaptation planning and funding for vulnerable countries. In order to reduce the effects of the more frightening heat waves, to reduce emissions we are creating that will need to adapt to the world of extreme heat very quickly. Stabilizing the climate by 2050 is better within a practical life time, as we are all allowed to prosper in this new world. There is no time to lose.
