Climate Crisis: The Fate of Our World

Updated on May 28, 2019

CLIMATE CRISIS (GLOBAL WARMING): THE FATE OF OUR WORLD

Warming and cooling of the Earth system are tied closely to imbalances between how much energy the system receives and how much it gives off.

While we talk about the climate crisis of this world, and the danger we face in coming times. There is only one possible situation to at least slow down the effect of what’s to come to us. But first, we will have to give at least some reasons why we expect a ‘climate crisis’, which shows why there is so much confusion regarding recent & future climate change or perhaps evolving into a ‘crisis and human involvement in it.

Here are some of those reasons;

First: The Earth system is large, and changes occurring in it vary from location to location and from time to time.

Second: The Earth has undergone a very long evolution, with vastly different conditions at different periods during those evolution's.

Third: Our data sets are painfully incomplete regarding both the past and ongoing climate changes, ranging from our readings in the hot weathers, the volcanoes, earthquakes among many others.

Fourth: The Earth system has many intertwined elements, changes in each of which can affect the others, and scientists are still learning about many of the interconnections.

Fifth: The models used to predict the future have numerous limitations, just like the ‘Hubble spacecraft’ gathering information’s for us from thousands of miles afar. Even in our science breakthroughs we can’t still prevent a ‘comet’ flying into our offices to move to a mass, or maybe aliens, (that some people believe in, though I don’t) from attacking us.

Sixth: The issues have become mired in strident controversy, with both sides at times presenting only one sides of the issues, and still with no clear picture of what we are dealing with, or what’s to come.

Energy coming into the Earth’s system is overwhelmingly radiation from the sun, termed ‘solar radiation’, whereas, energy leaving the Earth system includes both reflected solar radiation & radiation emitted outwardly by the Earth’s system, the latter termed ‘terrestrial radiation’. Natural mechanisms exist to keep the amount of radiation leaving the Earth system roughly in balance with the amount of radiation it receives.

If for instance, the Earth is sending out (by reflection and emission) more radiation than it is receiving, it will have the tendency to cool down, thereby causing it to emit less because of being cooler; by emitting less, the Earth will return to a rough equilibrium in its radiation budget, although at a cooler temperature than when the sequence began.

Similarly, if the Earth is ending out less radiation than it is receiving, it will have a tendency to warm up because of being hotter and will thereby again return to a rough equilibrium although this time at a high temperature. Hence, concern about global warming becomes a concern, for all of us.

So what if we are talking about a possible global pandemic, that will destroy this world if tomorrow anything gets to change in the upper heavens, if GOD decides to let go of everything in the solar heavens just for a second, and the ozone layer gets to sleep, or we have excess oxygen, we sure won’t have a second to spare before we die. Climate crisis doesn’t just start on its own, it starts with how we humans take control of the world we live in and everything we do to make it either better or worse. The world could be at its eclipse of destruction, the sun keeps getting hotter, the moon keeps getting cooler, seasons vary no longer as it should. The summer comes in the winter, and the winter in the summer, the dry season appears in the hamattan, the rainy season comes in the dry season. You don’t even know what could happen next year to come. Or maybe you don’t know, that the world spins faster than the previous years.

But the question is ‘are we the cause of this climate change or does it come by chance’?

Experts agree that the Industrial Revolution was the turning point when emissions of greenhouse effect gases entering the atmosphere began to soar. The Industrial Revolution was itself borne out of smaller revolutions: agricultural, technological, demographic, transport, finance… creating a new model of production and consumption.

From then onward, population growth (in 1750, there were fewer than 800 million people on Earth, whereas now we are over 7.5 billion), exploding resource use, increasing energy demand and production, mainly from fossil fuels, all saw the planet enter into what the scientific community have termed the Anthropocene period, a new geological era characterized by human impact on Earth.

The main impact was the increase in the global temperature of the planet, which has risen 1.1°C since this period, although it is estimated that, by the end of the present Century, the thermometer could rise by 2.7 °C even if national commitments to reduce emissions are fulfilled. Of course, it hurts actually to recognize the fact that a climate crisis could cause a damage in the planet that contains the only source of life so far.

Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.

According to the IPCC, the extent of climate change effects on individual regions will vary over time and with the ability of different societal and environmental systems to mitigate or adapt to change.

The IPCC predicts that increases in global mean temperature of less than 1.8 to 5.4 degrees Fahrenheit (1 to 3 degrees Celsius) above 1990 levels will produce beneficial impacts in some regions and harmful ones in others. Net annual costs will increase over time as global temperatures increase.

"Taken as a whole," the IPCC states, "the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time."

FUTURE EFFECTS OF A CLIMATE CRISIS

1. Change Will Continue Through This Century and Beyond

Global climate is projected to continue to change over this century and beyond. The magnitude of climate change beyond the next few decades depends primarily on the amount of heat-trapping gases emitted globally, and how sensitive the Earth’s climate is to those emissions.

2. Temperatures Will Continue to Rise

Because human-induced warming is superimposed on a naturally varying climate, the temperature rise has not been, and will not be, uniform or smooth across the country or over time 3. Frost-free Season (and Growing Season) will Lengthen

  • The length of the frost-free season (and the corresponding growing season) has been increasing nationally since the 1980s, with the largest increases occurring in the western United States, affecting ecosystems and agriculture. Across the United States, the growing season is projected to continue to lengthen.

    In a future in which heat-trapping gas emissions continue to grow, increases of a month or more in the lengths of the frost-free and growing seasons are projected across most of the U.S. by the end of the century, with slightly smaller increases in the northern Great Plains. The largest increases in the frost-free season (more than eight weeks) are projected for the western U.S., particularly in high elevation and coastal areas. The increases will be considerably smaller if heat-trapping gas emissions are reduced.
  • 4. More Droughts and Heat Waves Droughts in the Southwest and heat waves (periods of abnormally hot weather lasting days to weeks) everywhere are projected to become more intense, and cold waves less intense everywhere.
  • Summer temperatures are projected to continue rising, and a reduction of soil moisture, which exacerbates heat waves, is projected for much of the western and central U.S. in summer. By the end of this century, what have been once-in-20-year extreme heat days (one-day events) are projected to occur every two or three years over most of the nation. This risk doesn't only apply to the U.S, it will all rain down on the whole world, both places that are inhabited and uninhabited.

    Our world needs a lot of healing and what has to be done, must be done have that healing
