The science of climate change is getting more sophisticated, but many people still don’t fully grasp what it really means.
With the release of the UN’s first comprehensive report on climate change, we’ve rounded up some of the biggest questions about how the planet is changing, from how we’re going to survive it to what the next 10 to 15 years might bring.
How much does climate change really mean?
We know that carbon dioxide emissions are having a big effect on our climate, but the real question is what climate change actually means.
Is it more extreme than we thought, or more localized?
How will it impact human life in the future?
Will the planet continue to warm or cool as climate change intensifies?
The answer to all of these questions depends on what you think climate change means.
How does it compare to other types of climate impacts?
The basic idea is that climate change involves the spread of weather and climate-related extremes over a wide area.
The more intense the extremes, the more climate change there will be.
The increase in temperature in the Arctic, for example, means more extreme weather events like flooding and storm surges.
And it’s the increase in extreme weather over long periods of time that can have a significant impact on food and agriculture.
Climate change has also led to a range of more severe weather events, including droughts, flooding and wildfires.
Some scientists even argue that human activity has already caused the planet to warm by about 1.5 degrees Celsius (2.8 degrees Fahrenheit) over the last decade.
What do scientists know about how much CO2 we’ve released?
As the name suggests, CO2 emissions are the primary way we’re changing our climate.
But the CO2 levels that we emit aren’t the same as the total amount of CO2 in the atmosphere.
Scientists still don’ t have a perfect answer for how much we’ve emitted, because scientists aren’t really sure what the world’s CO2 concentrations will look like in the next few decades.
In the end, we can only guess what the atmosphere will look, based on our understanding of climate models.
How do climate change impacts compare to previous climates?
The past few decades have been incredibly hot and dry, but there have also been more extreme events, like the 2010 drought in the U.S. The United States, for instance, experienced the worst drought in more than 40 years, with nearly half of the country experiencing extreme rainfall and the flooding that occurred in the state of California alone.
In fact, scientists are predicting that the number of extreme events will more than double by 2050 as a result of climate warming.
Will climate change impact us as we age?
We’re getting older.
The amount of carbon dioxide in the air will increase at a rate that’s not only faster than the increase of CO3 levels, but it’s also going to be much more gradual.
As a result, it’s estimated that the world will end up with about 4.5 billion people living in cities by 2050.
The number of people over the age of 65 will also grow, as will the number who live in extreme urban areas.
But what does that mean for our planet?
Over time, the amount of energy that we produce is increasing faster than our planet itself.
It means that as the Earth gets warmer, the climate is getting hotter, and that in turn makes our planet more vulnerable to extreme weather.
If we continue to burn fossil fuels at the current rate, it will take thousands of years for CO2 to equal out and make up half of all the greenhouse gases in the Earths atmosphere.
That means that the amount that we can safely emit is increasing at a much faster rate than what we can keep the world in the carbon neutrality it has now.
That’s a problem for humanity.
Will the next decade bring more extreme storms?
If CO2 continues to rise, scientists say we could see more and more extreme tornadoes, droughty spells and wildfires that could have catastrophic impacts on people’s lives.
We could also see the number and type of extreme weather extremes increase dramatically.
For example, the number in a typical year will double from now to 2060, and extreme weather will more likely become more frequent.
If the CO 2 levels continue to increase, we may even see more severe droughting and flooding, which is also possible with a higher CO 2 concentration.
Are there any immediate risks?
The impacts of climate and climate change are still relatively unknown.
It’s possible that we’re already seeing some changes in our environment and climate, including more frequent, longer and stronger heat waves and droughms.
There are also some very severe consequences from climate change.
It could make it harder for people to travel or move around, as the number, type and severity of extreme heat events increase.
The most severe of these would be a “superstorm,” which is a series of hurricanes that occur when the average number of days in a year in
