What is climate change? What are its causes, effects, and solutions?
Climate change refers to long-term shifts in global weather patterns, primarily caused by human activities like burning fossil fuels, deforestation, and industrial emissions, leading to rising temperatures, extreme weather, and sea-level rise. Solutions include reducing carbon emissions, adopting renewable energy, and promoting sustainable practices.

The primary cause of climate change at present is humans burning everything in sight.

Causes of climate change in the past are 1) the sun 2) orbital mechanics 3) volcanoes 4) ocean circulation. Of the four, probably the most significant is orbital mechanics. This is the mechanism that results in ice ages. The other causes cause smaller changes.

One of the answers here claims it is the sun. Well, the sun used to be the major contributor but solar activity diverged from global temperature around 1960 when solar activity started to decrease, but temperature continued to rise. Recognize that CO2 was becoming more and more relevant even before this time. It just becomes clear at this point.

This claim was made by Alistair Riddoch: “It is KNOWN that when the Solar activity dipped a little in the 1960’s the Earth cooled a little. But during that time, the CO2 increased every single year. Temperature went the opposite direction of CO2. Because… The Sun Matters. Most. Much much more than humans. Much much more than CO2.”

The climate changes in a cycle of 100,000 years. No one knows why. It goes between ice ages and hot ages.

Greenhouse gases were a guess, but they do not change the temperature, they change when the temperature changes. So the higher the temperature, releases more CO2 etc. CO2 does not change the temperature.

There is a lot we do not know yet in science.

We know the daily cycle of rotation causes day and night every 24 hours, we know the yearly orbit with a tilted axis causes the four seasons on an annual cycle.

We know our base line temperature of the planet is set by our distance from the Sun.

We know the Milankovitch cycles have an effect.

There are two outcomes, the temperature goes down, which causes an ice age. The temperature goes up which causes a warm age. They are spread about 100,000 years apart, so something must happen every 100,000 years which causes them.

Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time. For example, 20,000 years ago, much of the United States was covered in glaciers. In the United States today, we have a warmer climate and fewer glaciers.

Global climate change refers to the average long-term changes over the entire Earth. These include warming temperatures and changes in precipitation, as well as the effects of Earth’s warming, such as:

Rising sea levels
Shrinking mountain glaciers
Ice melting at a faster rate than usual in Greenland, Antarctica and the Arctic
Changes in flower and plant blooming times.
Earth’s climate has constantly been changing — even long before humans came into the picture. However, scientists have observed unusual changes recently. For example, Earth’s average temperature has been increasing much more quickly than they would expect over the past 150 years.

There are lots of factors that contribute to Earth’s climate. However, scientists agree that Earth has been getting warmer in the past 50 to 100 years due to human activities.

Certain gases in Earth’s atmosphere block heat from escaping. This is called the greenhouse effect. These gases keep Earth warm like the glass in a greenhouse keeps plants warm.

Human activities — such as burning fuel to power factories, cars, and buses — are changing the natural greenhouse. These changes cause the atmosphere to trap more heat than it used to, leading to a warmer Earth.

What causes environmental change?

Earth is an extremely unique planet – its circles sufficiently close to the sun to get a considerable measure of vitality, however sufficiently far away not to be seared.

It is in what you may call the "goldilocks zone", where the conditions are simply a good fit for life as we probably am aware it.

To keep these conditions consistent, our planet is wrapped in a layer of nursery gasses.

This layer demonstrations like a sweeping, keeping the earth warm and protecting it from the cool of universe. This is generally alluded to as the nursery impact.

Carbon dioxide (CO2), which, while not the most strong nursery gas, is by the by the principle driver of the nursery impact.

At the point when fossil powers - coal, oil and common gas - are blazed they discharge CO2 into the air.

In light of this the layer of nursery gas is getting thicker, which is thus making the Earth hotter.

In this way the continuous boundless blazing of fossil powers is the reason for environmental change.

Keeping in mind the end goal to fulfill our perpetual strive after vitality we are buring boundless amounts of fossil fills.

In any case, this does not need to be the situation, because of human resourcefulness there are presently more brilliant approaches to make vitality.

About Carbon Dioxide

CO2 can be sufficiently innocuous when broken up in a beverage – it adds shimmer to mineral water, soda pops and champagne. In any case, when overabundance sums are discharged into the climate it can bring about untold harm. How CO2 causes a dangerous atmospheric devation.

Where does CO2 originate from?

As far as energizes, the principle issue is coal. The other key reason is waste – wasteful utilization of vitality.

Also, as far as commercial ventures, the principle offender is power creation – the force business.

The greatest atmosphere polluter is the worldwide force part which produces around 40% of all worldwide power from coal. We require power - yet when you consider the genuine expense of coal there are vastly improved approaches to get it!

By International Energy Agency the force segment is in charge of 37% of all man-made Carbon Dioxide (CO2) discharges. It makes around 23 billion tons of CO2 outflows every year – in abundance of 700 tons a second.

Thus, this CO2 keeps on warming up our planet which represents an exceptional danger to us and nature.

Producing power through the smoldering of fossil fills, specifically carbon-substantial coal, greaterly affects the environment than whatever other single human movement.

Coal is the world's most generally accessible fossil fuel

Weaning mankind off coal won't be simple. There is an expected 2 billion individuals with no entrance to local power, and recoverable stores of coal exist in around 70 nations, as indicated by the World Coal Institute, an industry hall assemble (the biggest stores are in the United States, Russia and China). Coal is viewed as a shabby type of vitality.

In any case, coal is not shoddy - in the event that you need to pay for it all

The genuine expense of coal is not found on any asset report, but rather in the lives and soundness of individuals and environments. In the event that the worldwide force area could be made completely responsible for the genuine expenses of contamination and environmental change, it would most likely move in the opposite direction of fossil fuel overnight.

An excess of governments still finance coal generation which mutilates the vitality market. OECD nations bolster their coal industry with an incredible US$30 billion every year.

Much cleaner renewable energies are hampered in their capacity to rival a messy fuel that is so vigorously financed. Government officials have the ability to evacuate fossil-fuel endowments or, even better, exchange them to renewable vitality.

Climate change is natural, ongoing and not at all harmful as long as we are getting warmer.

When this warming ends, 50 to 500 years from now, climate change will be bad.

Scientists, paid to support climate alarmism do , scientists who are not paid ,in general ,do not believe human activity has a significant effect.

The rate of sea level change is constant or diminishing, as many glaciers are expanding as contracting, we are only told about the shrinking ones, not the expanding ones.

It was the warmest 7000 years ago and has not been as warm since, humans or not! more stuff we are not told, but is findable if you look.

The effects of CO2 are logarithmic , meaning that each additional CO2 molecule does less. The first 80 ppm of CO2 absorb 80% of all the incoming radiation that CO2 absorbs as a greenhouse gas. The next 20ppm absorbs 80% of the remaining energy, so does the next 20ppm, etc, etc. By the time we get to 200 ppm CO2 is no longer acting as a greenhouse gas and adding more does not effect the greenhouse effect at all

The causes are multiple and natural.

What is climate change? What are its causes, effects, and solutions?

Climate is weather, but averaged out for several decades. It is always changing. Some of these changes are fairly cyclical, such as the oscillation of the sea surface temperatures in the eastern tropical Pacific Ocean and their relationship with the atmospheric winds. Some changes in climate are abrupt but short lived (in geological time), such as the cooling of global temperatures due to suspended ash from large volcanic eruptions.

In modern parlance, “climate change” has become synonymous with “global warming”. Global warming, a term which I prefer because it’s more precise than climate change, is the warming of the average global temperature over the past century or so. It’s mostly a result of man-made increases in carbon dioxide (generated by the combustion of fossil fuels).

Although the global average temperature is rising, it is not doing so uniformly. This results in different types and degrees of climate change from region to region. While scientists are in good agreement in the cause of global warming and the continued rise in temperature due to increasing carbon dioxide, the effects of this warming is not as clear.

What are possible solutions? Some people advocate a radical reduction in carbon dioxide emissions by relying primarily on so-called “green energy” (solar power, wind power, etc.). I think it’s unrealistic to suddenly abandon inexpensive fossil fuels for very expensive green energy sources as it would ruin the world economy.

Man will have to one day abandon his reliance on fossil fuels as there’s only a finite supply. However, our technology has not yet evolved to a point where we can abandon fossil fuels. Nuclear power, if properly regulated, could result in a drastic reduction in carbon dioxide emissions but the storage of spent fuel is a major hurdle.

For the next century, I believe our best approach is to concede that different regions will have to take different steps to mitigate the possible negative effects of generally warming global temperatures. For instance, as sea levels continue to rise, coastal zones might have to enact new building and zoning codes to help avoid economic disasters. Some regions of the world might actually benefit from climate change, provided the people there adapt their economy and lifestyles to the new climate.
