The Republicans have no climate strategy nor legislation;  Except to burn more natural gas (methane a potent greenhouse gas). 
However methane leaks all along the supply chain are big enough to make  burning methane as bad as burning coal. Not one Republican voted for the latest critical climate legislation. 
While Earth’s climate has changed throughout its history, the current warming is happening at a rate not seen in the past 10,000 years.

Key findings from the IPCC’s 6th Assessment Report: The Physical Science Basis:

  • Concentrations of CO2 in the atmosphere were higher than at any time in at least two million years
  • Global surface temperature was  2.F higher in 2011– 2020 than avg. 1850–1900. Most of the warming occurred in the past 40 years, with the seven most recent years being the warmest. The years 2016 and 2020 are tied for the warmest year on record.
  • Global temperatures will continue to rise until at least 2050, even if greenhouse gas emissions were to stop today
  • Human influence is very likely the main driver of the global retreat of glaciers since the 1990s.
  • Glaciers are melting at rates unprecedented in human history.
  • The loss of reflective snow/ ice means sunlight penetrates the oceans warming them more.
  • In 2011–2020, annual average Arctic sea ice area reached its lowest level since at least 1850. 
  • More “extreme weather events” (floods, fires, hurricanes) have begun happening even faster than expected. The rate of extreme events in 2020 was initially forecast for the year 2100.
  • Droughts have tripled in the last 50 years, fisheries have collapsed due to extreme heat events, and over 20 million people have been displaced due to extreme weather events  in the last ten years.
  • Global agricultural productivity has actually decreased due to changes in rainfall patterns, increased Temperatures, increase in fungal infestations, and numerous other causes.
  • Roughly half the world population is experiencing “water scarcity” for at least one month per year
  • Nearly half a billion people are experiencing “unfamiliar precipitation patterns”—droughts in some places, flooding in others.
* The Ice Sheets Are Shrinking:  The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA’s Gravity Recovery and Climate Experiment show Greenland lost an average of 279 billion tons of ice per year between 1993 and 2019, while Antarctica lost about 148 billion tons of ice per year.
* Sea Level Is Rising :
Global sea level rose about 8 inches (20 centimeters) in the last century. The rate in the last two decades, however, is nearly double that of the last century and accelerating slightly every year.
* Extreme Events Are Increasing in Frequency : The number of record high temperature events in the United States has been increasing, while the number of record low temperature events has been decreasing, since 1950. The U.S. has also witnessed increasing numbers of intense rainfall events.
* Ocean Acidification Is Increasing : Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30%. This increase is due to humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the ocean. The ocean has absorbed between 20% and 30% of total anthropogenic carbon dioxide emissions in recent decades (7.2 to 10.8 billion metric tons per year).
* Global Wildfires are increasing;  * Polar Bears & Most Coral Reefs are doomed to die.
* Permafrost (land in Russia; Canada; Greenland ) frozen since last ice age is warming & releasing greenhouse gases.

* The following  lists the nearly 200 worldwide (Including American) scientific organizations that hold the position that climate change has been caused by human action.

* How fast is the Climate changing ? 

In 100 years, atmospheric CO2 levels have increased over 120 ppm,

Imagine you are 20 years old, 5 feet 6, and weigh 150 pounds, with a body mass index (BMI) of 24 (healthy).

– If you gain two pounds / year for 50 years, at 70, you’ll weigh 250 lbs; have a BMI of 40 (obese).

-An alternative is that you gain two pounds / week for a year.  By the end of the year, you’ll weigh 254 pounds.

These are two different rates of change with drastically different consequences.

For atmospheric CO2, we are on the two pounds per week trajectory.

Without further policy action, we’re probably on a path to  Catastrophic 3.2 C (5.8 F) warming.   
* The world must rapidly stop burning all fossil fuels to prevent Hot House Earth:  * International Energy Agency: 2021

“Nations around the world would need to immediately stop approving new coal-fired power plants and new oil and gas fieldsand quickly phase out gasoline-powered vehicles if they want to avert the most catastrophic effects of climate change”
the IPCC  report makes clear that enough fossil-fuel infrastructure to blow past the goal has already been built.  
The world’s existing fossil-fuel infrastructure would generate another 660 to 850 gigatons of emissions. Vs the 400 GT limit.
Meeting the goal will require taking coal, oil, and natural-gas capacity offline before it was designed to shut..
* A stark future for ocean life:  
“Accelerating ocean warming and de-oxygenation  threaten a mass extinction rivalling the worst in Earth’s history, especially for cold water species, such as the Atlantic rock crab shown here.”The year 2021 marked the highest temperature and likely the lowest oxygen content for the oceans since human records began (1, 2). These changes have put marine species on the front lines of climate change.* Marine species’ geographical ranges are shifting faster and experiencing more contractions than those of terrestrial species.
NOTE: Shellfish Can not migrate !
*More than 50 % of global ocean have crossed Extreme heat threshold ev consecutive yr since 2014… Vs less 2 % since records kept
* All life has physiological limits:   Adverse  & death Fish;  Coral; phytoplankton;  .. 
Fresh water Lakes are also heating up.
60 % of fish species Globally will struggle to Reproduce in their current spawning habitats by 2100”.. – study of nearly 700 salt and freshwater species 
No matter where you live, you will be affected by climate change.
Heat domes will be annual events, not the thousand-year events as they have been described recently. Massive forest fires will no longer be “seasonal” and could explode at any time.
A critical issue missed by so many is that instability is the most dramatic consequence of climate change. The unstable polar jet stream will cause unpredictable swings in rainfall patterns several times each year. Heavy rains one week followed by weeks of dry winds that parch the already desiccated landscape turning surviving foliage into a tinderbox that could ignite at any moment. A warmer atmosphere can hold more moisture resulting in massive storms and significant flooding. Crop losses from too much rain too fast will become common.     SEE: Six Degrees: Our Future on a Hotter Planet by Mark Lynas and his follow-up Our Final Warning: Six Degrees of Climate Emergency provide insight into our possible (probable) future.
