So many times that ichipululu would not know what exactly is weather or is it climate change, more specifically, weather is the mix of events that happen each day in our atmosphere. Even though there’s only one atmosphere on Earth, the weather isn’t the same all around the world.
Weather refers to atmospheric conditions in the short term. Weather is different in different parts of the world and changes over minutes, hours, days and weeks. Most weather happens in the part of Earth’s atmosphere that is closest to the ground called the troposphere. And, there are many different factors that can change the atmosphere in a certain area like air pressure, temperature, cloudiness, brightness, visibility, humidity, wind speed and direction, and lots of other things. Together, they determine what the weather is like at a given time and location.
Whereas weather refers to short-term changes in the atmosphere, climate is the average of weather patterns over a longer period of time in a specific area. Different regions can have different climates. To describe the climate of a place, we might say what the temperatures are like during different seasons, how windy it usually is, or how much rain or snow typically falls. So the next time you hear someone question climate change by saying, “You know it’s freezing outside, right?” you can gladly explain the difference between weather and climate.
When scientists talk about climate, they’re often looking at averages of precipitation, temperature, humidity, sunshine, wind, and other measures of weather that occur over a long period in a particular place. In some instances, they might look at these averages over 30 years. And, we refer to these three-decade averages of weather observations as Climate Normals.
While descriptions of an area’s climate provide a sense of what to expect, they don’t provide any specific details about what the weather will be on any given day. Looking at Climate Normals can help us describe whether the summers are hot and humid and whether the winters are cold and snowy at a particular place. They can also tell us when we might expect the warmest day of the year or the coldest day of the year at that location. But, while descriptions of an area’s climate provide a sense of what to expect, they don’t provide any specific details about what the weather will be on any given day.
So in short ichipululu can say here’s one way to visualize it. Weather tells you what to wear each day. Climate tells you what types of clothes to have in your closet.
Across the globe, observers and automated stations measure weather conditions at thousands of locations every day of the year. Some observations are made hourly, others just once a day. Over time, these weather observations allow us to quantify long-term average conditions, which provide insight into an area’s climate. While the weather can change in just a few minutes or hours, climate changes over longer time frames. Climate events, like El Niño, happen over several years, with larger fluctuations happening over decades. And, even larger climate changes happen over hundreds and thousands of years.
Today, climates are changing. Our Earth is warming more quickly than it has in the past according to the research of scientists. Hot summer days may be quite typical of climates in many regions of the world, but warming is causing Earth’s average global temperature to increase. The amount of solar radiation, the chemistry of the atmosphere, clouds, and the biosphere all affect Earth’s climate.
As global climate changes, weather patterns are changing as well. While it’s impossible to say whether a particular day’s weather was affected by climate change, it is possible to predict how patterns might change.
Climate change and its impacts on weather events affect people all around the world. Climate change is happening, it is largely caused by human activities, and it presents a serious threat to nature and people now, and also in the future. Without ambitious mitigation efforts, rising global temperatures are expected to further raise sea levels and change precipitation patterns and other local climate conditions. global temperature rise this century could exceed 4 degrees Celsius above pre-industrial levels, with catastrophic impacts.
Changing regional climates could alter forests, crop yields, and water supplies. They could also affect human health, animals, and many types of ecosystems. Deserts may expand into existing rangelands, and features of some of our National Parks and National Forests may be permanently altered.
