Climate Change
Climate Change
Long-term changes in temperature and weather patterns are referred to as climate change. These changes could be caused by natural processes, such oscillations in the solar cycle.
Since the 1800s, human activities—primarily the combustion of fossil fuels like coal, oil, and gas—have been the primary cause of climate change.

Fossil fuel combustion produces greenhouse gas emissions that serve as a blanket around the planet, trapping heat from the sun and increasing temperatures.
Carbon dioxide and methane are two examples of greenhouse gas emissions that are contributing to climate change. These are produced, for instance, while burning coal or gasoline to heat a building. Carbon dioxide can also be released during forest and land clearing. Methane emissions are primarily produced by waste landfills. Among the major emitters are energy, industry, transportation, buildings, agriculture, and land use.
The amount of greenhouse gases is at its highest point in two million years.

And emissions keep increasing. The latest research proves that the Earth has warmed by around 1.1°C since the late 1800s. The most recent ten years (2011–2020) were the warmest ever.
Reduced emissions from fossil fuel-based power systems will result from switching to renewable energy sources like solar and wind. But we must get started immediately. While more nations are pledging to have net zero emissions by 2050, roughly half of the reductions in emissions must be in place by that year in order to keep global warming at or below 1.5°C. Between 2020 and 2030, fossil fuel production must decrease by around 6% annually.
Everyone benefits from adaptation to climatic effects. Both current and likely future effects are covered. Everyone, everywhere, will need to adapt and make adjustments, but the most vulnerable individuals must receive priority immediately because they have the fewest resources available to them. A high rate of return is probable. For instance, early warning systems for natural disasters save many lives and valuable property, and they can generate financial gains up to ten times their initial cost.
We can pay now, or with interest in the future.

"In our obscurity, in our vastness, there is no hint that help will come from elsewhere to save us from ourselves. It is up to us."-Carl Sagan
" We are in the beginning of a mass extinction and yet all you can talk about is money and fairy tales of eternal economic growth. How dare you!"- Greta Thunburg
"An organism at war with itself is doomed."-Carl Sagan
"I don't want you to be hopeful. I want you to panic. I want you to feel the fear that I feel everyday. I want you to act. I want you to act like you would in a crisis. I want you to act like your house is on fire, because it is." - Greta Thunberg
"You say you love your children above all else, and yet you are stealing their future in front of their very eyes." - Greta Thunberg
"One of history's saddest lessons is this: if we've been bamboozled long enough, we tend to reject any evidence of the bamboozle. We are no longer interested in finding out the truth. The bamboozle has captured us. It is simply too painful to acknowledge, even to ourselves, that we've been taken. Once you give a charlatan power over you, you almost never get it back."-Carl Sagan
"We are dumping Carbon Dioxide into the atmosphere at a rate the earth hasn't seen since the great climate catastrophes of the past. The ones that led to mass extinctions. We just can't seem to break our addiction to the kinds of fuel that will bring back the climate last seen by the dinosaurs, a climate that will drown our coastal cities and wreck havoc on the environment and our ability to feed ourselves... Why can't we summon the ingenuity and courage of the generations that came before us?
The dinosaurs never saw that asteroid coming.
What's our excuse?" -Neil DeGrasse Tyson
