Unexpected Effects Of Climate Change
The effects of climate change are discussed all the time. We hear a lot about rising seas, extreme weather events, and so on. And mostly, the weather gets warmer. Heatwaves are increasingly common and longer and stronger.
Traffic Jams In The Jet Stream
Many extreme weather events are associated with unusual behavior by the jet stream. Jet streams are the global air currents that circle the earth. The meandering and speed changes in the jet stream affect weather and also play a big role in how long it takes aircraft to make their way across the country. The behavior that leads to extreme weather events is known as “blocking” in which the meandering jet stream stops weather systems from moving eastward.
Saving Wheat
Rising temperatures, drought, pests and diseases are moving north into the U.S. heartland and are increasingly posing a threat to the wheat crop. An insect called the Hessian fly is reducing crop yields by 10% a year in the Midwest. Average temperatures in the Midwest have risen by 2 degrees since 2000, and periods of time between rainfalls is lengthening. Conditions in some areas of the Midwest are getting to be more like those in the Middle East.
Cold Weather In A Warming Climate
The climate is warming. The average global temperature is going up year after year, bringing about significant changes to weather around the world. But the fact is that these changes don’t always lead to warmer weather. And ordinary variations in local weather can also go in either direction.
Climate Change And Temperature Variations
It’s no surprise that not everyone on the planet is equally responsible for the effects of climate change. For instance, the Northern Hemisphere, which is home to 13 of the 15 largest countries by GDP, emits far more greenhouse gases than the Southern Hemisphere does. But the whole planet heats up as a result.

FEMA And Climate Change
In 2017, the United States spent a record $306 billion on weather and climate-related disasters, making it the costliest and most damaging year on record. The wildfires out west, Hurricanes Irma, Maria, and Harvey, the Minnesota hailstorm, and the midwest drought are just some of the costly examples. Officials say that already-bloated figure will increase further in the coming years as temperatures rise.
Cold And Snow From Global Warming
The Arctic has been experiencing record warm temperatures and record low sea ice levels. During February, there were nine days in a row with temperatures averaging 27 degrees above normal and often above freezing. Over the previous 20 years, there were only two previous readings above freezing in February – once in 2011 and once last year.
2017 Was Hot
There’s no argument to be made about whether 2017 was hot or not. The only uncertainty is whether it was the second or third warmest year ever recorded.
Climate Change Threatens the U.S. Military
According to a new study from the Pentagon, nearly half of United States military sites are threatened by wild weather linked to climate change. The U.S. Department of Defense states that drought, wind, and flooding that occur due to reasons other than storms topped the list of natural disasters that endanger 1,700 military sites around the world – everything from outposts to large bases.

Climate Change And Barley
The impacts of increased carbon dioxide and the changing climate are often complicated and, it turns out, not always negative. In some areas of the world, people can actually benefit from increased CO2 and climate change. Barley, the most important feed crop for beef production in Alberta, Canada, as well as the province’s beef industry itself actually stand to gain from the changes that are most assuredly not a good thing for much of the world.
Being Ready For Adverse Weather
Severe weather is a major cause of death and destruction. Recent hurricanes provided all too many examples. The catastrophic flooding from Hurricane Harvey led to more than 60 deaths and necessitated thousands of emergency rescues. And yet, increasingly, weather events like hurricanes don’t occur without warning and accurate weather forecasts are increasingly common.
Climate Change And Hawaii
The Hawaiian Islands are an archipelago of eight major islands, several atolls, numerous smaller islets, and seamounts in the North Pacific Ocean. The islands are a world-renowned vacation spot, known for their white-sand beaches, lush flora, and near perfect weather. But stormier days may be ahead.
The Delhi Air Pollution Crisis
Delhi, the capital city of India, has always been a city bursting at the seams. With over 19 million people, heavy industry, growing numbers of vehicles, and choking amounts of road dust, Delhi suffers from some of the worst air pollution in the world. It is a situation the country has been struggling with for years.
A Decline In Flying Insects
When was the last time you used a squeegee to remove squashed insects from your windshield? It’s been a while, right? It’s not just you. This is known as the windscreen phenomenon. Scientists and some motorists have long suspected that flying insects are in dramatic decline. New research has confirmed these suspicions.
Winter Outlook
Each year around this time, the National Oceanic and Atmospheric Administration, or NOAA, releases its U.S. Winter Outlook that predicts overall weather trends around the country for the upcoming winter. They produce these seasonal outlooks to help communities prepare for the weather that is likely to be forthcoming.
Climate Change And Hurricanes
No single weather event can be attributed to climate change. Storms, floods and droughts have always happened and some of them have always been severe. However, two centuries of people burning fossil fuels has altered temperatures just enough that some of the storms we have seen in recent times have been much worse than they otherwise would have been.
The Terminology Of Extreme Weather
We often hear the terms “100-year” and “500-year” used to describe instances of extreme flooding. But as the climate changes, these extreme weather events are expected to become more frequent. So what’s with the terminology then anyways?
Fern-Inspired Energy Storage
The amount of solar energy striking the surface of the earth in two hours is enough to supply all of humankind’s needs for an entire year. For this reason, it is widely thought that solar energy should be our primary source of electricity. If this is to happen, however, there must be cost-effective ways to obtain solar electricity regardless of the time of day, weather, or seasonal changes. Essentially, there must be ways to store the energy from the sun to use it when we need it.
Islands Ditching Diesel
Islands around the world have a difficult time developing the infrastructure for electricity generation. Many are simply too small or too poor for conventional power plants. The most common electricity source on islands is diesel generators which are not environmentally friendly and result in some of the most expensive electricity in the world.
