Climate Change

Climate change has been going on well before recorded history and will continue to do so. Human civilization has adapted in some cases and in others not so much I& at all and it is not reasonable to expect the climate to not vary for human convenience. There are examples of local devastation such as in northern Indian and Pakistan where accelerated glacial melts have resulted in major flooding , so for the locals, “the sky has fallen”
I know of some Blue Mountain sky operations that are hurting too.
The only times in history the planet have changed as much as fast were from asteroid or super volcano.
Adapting to an AMOC shutdown would suck massively and its likely to happen in the near future.
You should check it out.
Oil$gas just wants more of this.

At your earliest convenience, please provide at least two more reliable sources that you would recommend.
Than you in advance for your response.
Floods and warm periods have happened for thousands of years.
If tomorrow a huge flood happened that would flood most of Holland, Scandinavia and Germany, you would probably blame that on climate change as well.
And yet this did happen, but it happened in 1717 which obviously cannot be attributed to global warming

The list of historical floods is a long one: https://en.wikipedia.org/wiki/List_of_floods
As far as glaciers melting, I'm sure that has happened throughout history as well, but since record keeping was pretty much non-existent we'll never know for sure

Large patch of the Atlantic Ocean near the equator has been cooling at record speeds — and scientists can't figure out why
Scientists are trying to decipher what drove the recent dramatic cooling of the tropical Atlantic, but so far few clues have emerged. "We are still scratching our heads as to what's actually happening," the researchers said.

40 years?
how long have we had accurate and semi- complete data on the surface temperature of the oceans ?
50 years maybe ?
how long have the ever changing oceans been around?
Solar Panels Are Starting to Die, Leaving Behind Toxic Trash
Photovoltaic panels are a boon for clean energy but are tricky to recycle. As the oldest ones expire, get ready for a solar e-waste glut.

Rape is rape….Lithium or Oil…
Just because its too hard for you to too understand doesn't mean other people can't.

You really think oil and coal leaves no mess?
alberta has a $250 billion bill for cleaning up old oil wells.
i understand the difference between propaganda and scientific facts
you do not
what you truly understand about the science of our extremely complex, non-linear, dynamic climate system would not fill a dixie cup
you reject / ignore fundamental laws of nature in order to push your failed socialist agenda
your views are of zero value
please go finish your high school equivalence requirements
They both pollute. Oils and gas are just more reliable at the moment. So why not just use them until we find a better way.
Exactly. But why use the one that's inefficient. It just wastes resources and leaves the same garbage.
What do you mean by inefficient?
The lithium battery in your phone can recharge 1000 times. The ones in most EVs can recharge 4000 times. The newest ones in EVs can be recharged 20000 times, it can last for 50 years if you fully discharge and charge (~400 km) once a day, if you drive 100km a day that battery will last 200 years.
How many times can you use the same gasoline? Once.

They are not remotely on the same level.
Global Energy Footprint
How does energy production affect health, environment, climate and economy?
energy.glex.no
How many times can you drive the same ICE car? Probably
as many times as you can drive an EV.
How many times you have to charge an EV? Maybe
roughly about as many times as you have to fill up
an ICE car.
What is the efficiency of charging and running an EV by
comparison to an ICE car?
That really depends on the energy source. A Tesla
in China is likely charged by coal-generated electric
power. Here in Canada it could be electricity produced
from a natural gas-powered generator, nuclear power
plant or water hydro power.
Construction, maintenance and fueling an EV is
rather energy intensive. Manufacturing and production of
materials and metals required to build an EV is likely to be
more damaging to the environment than what is entailed
in building an ICE car. One thing is certain though, an EV
running on lithium battery is not as affordable to the less
affluent than an ICE car irrespective of its energy efficiency.

This is the only part of your reply that seems coherent, the rest is your usual meandering ramblings.
I asked chatGPT that question because google search did a sh*t job.
What is the efficiency of charging and running an EV by comparison to an ICE car?
ChatGPT said:
When comparing the efficiency of charging and running an electric vehicle (EV) to an internal combustion engine (ICE) car, several factors come into play. Here’s a breakdown of the key points:
Energy Efficiency
- EV Efficiency:
- Electric Motor Efficiency: Electric motors are highly efficient, with typical efficiencies ranging from 85% to 95%. This means that most of the electrical energy stored in the battery is converted into motion.
- Energy Use: EVs often use about 0.2 to 0.3 kWh per mile, translating to roughly 3 to 5 miles per kWh.
- ICE Car Efficiency:
- Combustion Engine Efficiency: ICE engines are less efficient, typically converting only about 20% to 30% of the energy in gasoline into useful motion. The rest is lost as heat and friction.
- Energy Use: ICE cars usually achieve about 20 to 30 miles per gallon, which is roughly equivalent to 0.033 to 0.05 gallons per mile.
- EVs:
- Power Generation: The efficiency of generating electricity varies based on the source. Coal-fired power plants are less efficient (around 30% efficiency), while natural gas plants are somewhat better (around 45% efficiency). Renewable sources like wind and solar can be nearly 100% efficient in terms of converting natural resources into electricity.
- Transmission Losses: There are losses associated with transmitting electricity from power plants to charging stations and then to the vehicle. These losses are typically around 5-10%.
- ICE Cars:
- Fuel Extraction and Refinement: The efficiency of extracting, refining, and transporting gasoline or diesel contributes to overall inefficiency. This process typically involves losses of around 10-15%.
- Overall Efficiency: Combining engine efficiency with fuel extraction, refining, and distribution, ICE vehicles often have a well-to-wheel efficiency of around 15-20%.
- EVs:
- Emissions: EVs produce no tailpipe emissions, which can significantly reduce overall emissions if charged from renewable sources.
- Maintenance: EVs generally require less maintenance because they have fewer moving parts and no need for oil changes.
- ICE Cars:
- Emissions: ICE vehicles emit CO2 and other pollutants directly from the tailpipe. Their environmental impact can be reduced with improvements in fuel efficiency and emission controls, but they still contribute to air pollution and greenhouse gas emissions.
- Maintenance: ICE vehicles typically require more frequent maintenance, including oil changes, and have a more complex mechanical system.
In summary, EVs are generally more energy-efficient than ICE vehicles. The higher efficiency of electric motors compared to combustion engines, combined with the potential for using renewable energy sources, makes EVs a more efficient choice in terms of energy consumption and environmental impact. However, the overall efficiency of EVs can be affected by the sources of electricity used for charging and the energy losses in the power generation and distribution process.
