As the world continues to warm from the increase in greenhouse gases, the coming decades are likely to bring hurricanes that intensify even more rapidly.
As the climate changes, fall is not as cool as it used to be, and cooler weather is being delayed until later in the season. This change affects the growing season, the allergy season, the insect population, and fall foliage.
Climate change is causing temperatures to rise throughout the year, but some seasons are warming faster than others. As we approach the start of meteorological winter on December 1st, we see that winter is warming the fastest in most of the country.
The spring season is heating up across the country. Extra heat accelerates evaporation that can lead to drought and stressed water supplies, affecting agriculture and energy systems as well as cities and towns. Nationwide impacts of warmer springs include longer pollen and pest seasons.
As additional carbon pollution continues to trap more and more heat in the atmosphere, the higher hot temperatures that result can come with a hefty price tag. Some of those costs hit our wallets in the form of higher energy bills from greater use of air conditioning. Warmer temperatures can also have major health impacts, increasing our vulnerabilities to allergies, asthma, heat stroke and even death.
According to a survey conducted by the Department of Defense between 2013 and 2015, at least one military site in every state has been negatively affected by some type of extreme weather, flooding, or wildfire. The survey indicated that damage has been done to airfield operations, training facilities, and transportation and energy infrastructure. As global warming continues these risks will grow.
