Using this ancient evidence, scientists have built a record of Earth’s past climates, or “paleoclimates.” The paleoclimate record combined with global models shows past ice ages as well as periods even warmer than today. But the paleoclimate record also reveals that the current climatic warming is occurring much more rapidly than past warming events.
As the Earth moved out of ice ages over the past million years, the global temperature rose a total of 4 to 7 degrees Celsius over about 5,000 years. In the past century alone, the temperature has climbed 0.7 degrees Celsius, roughly ten times faster than the average rate of ice-age-recovery warming.
Models predict that Earth will warm between 2 and 6 degrees Celsius in the next century. When global warming has happened at various times in the past two million years, it has taken the planet about 5,000 years to warm 5 degrees. The predicted rate of warming for the next century is at least 20 times faster. This rate of change is extremely unusual.

Earth is finishing up its warmest year in the past 174 years, and very likely the past 125,000.
Unyielding heat waves broiled Phoenix and Argentina. Wildfires raged across Canada. Flooding in Libya killed thousands. Wintertime ice cover in the dark seas around Antarctica was at unprecedented lows.
This year’s global temperatures did not just beat prior records. They left them in the dust. From June through November, the mercury spent month after month soaring off the charts. December’s temperatures have largely remained above normal: Much of the Northeastern United States is expecting springlike conditions this week.
That is why scientists are already sifting through evidence — from oceans, volcanic eruptions, even pollution from cargo ships — to see whether this year might reveal something new about the climate and what we are doing to it.

During the first six weeks of the war in Gaza, Israel routinely used one of its biggest and most destructive bombs in areas it designated safe for civilians, according to an analysis of visual evidence by The New York Times.
The video investigation focuses on the use of 2,000-pound bombs in an area of southern Gaza where Israel had ordered civilians to move for safety. While bombs of that size are used by several Western militaries, munitions experts say they are almost never dropped by U.S. forces in densely populated areas anymore.

Gaza Deaths Surpass Any Arab Loss in Wars With Israel in Past 40 Years
The death toll reported in Gaza has reached roughly 20,000, according to officials in the territory, the heaviest loss on the Arab side in any war with Israel since the 1982 Lebanon invasion.
I have ordered a complete siege on the Gaza Strip. There will be no electricity, no food, no fuel, everything is closed. We are fighting human animals and we act accordingly.
Gaza won’t return to what it was before. We will eliminate everything.
Several times in Earth's history, rapid global warming occurred, apparently spurred by amplifying feedbacks. In each case, more than half of plant and animal species became extinct. New species came into being over tens and hundreds of thousands of years. But these are time scales and generations that we cannot imagine.

There is a an important psychological aspect to climate change, that it demands a huge transformation in ones fundamental understanding of oneself, of humanity, of society and economics, and a change of direction away from endless growth that threatens ones' identity like no other issue. Denial is commonplace, and particularly denial that anything is happening that will radically change the way of life of the human world. — unenlightened

We already see effects scientists predicted, such as the loss of sea ice, melting glaciers and ice sheets, sea level rise, and more intense heat waves.
Scientists predict global temperature increases from human-made greenhouse gases will continue. Severe weather damage will also increase and intensify.
Some changes (such as droughts, wildfires, and extreme rainfall) are happening faster than scientists previously assessed. In fact, according to the Intergovernmental Panel on Climate Change (IPCC) — the United Nations body established to assess the science related to climate change — modern humans have never before seen the observed changes in our global climate, and some of these changes are irreversible over the next hundreds to thousands of years.
Scientists have high confidence that global temperatures will continue to rise for many decades, mainly due to greenhouse gases produced by human activities.
So, the Earth's average temperature has increased about 2 degrees Fahrenheit during the 20th century. What's the big deal?
The IPCC’s Sixth Assessment report, published in 2021, found that human emissions of heat-trapping gases have already warmed the climate by nearly 2 degrees Fahrenheit (1.1 degrees Celsius) since 1850-1900.1 The global average temperature is expected to reach or exceed 1.5 degrees C (about 3 degrees F) within the next few decades. These changes will affect all regions of Earth.
The severity of effects caused by climate change will depend on the path of future human activities. More greenhouse gas emissions will lead to more climate extremes and widespread damaging effects across our planet. However, those future effects depend on the total amount of carbon dioxide we emit. So, if we can reduce emissions, we may avoid some of the worst effects.
"The scientific evidence is unequivocal: climate change is a threat to human wellbeing and the health of the planet. Any further delay in concerted global action will miss the brief, rapidly closing window to secure a liveable future."

Future effects of global climate change in the United States:
Here are some of the expected effects of global climate change on the United States, according to the Third and Fourth National Climate Assessment Reports.
U.S. Sea Level Likely to Rise 1 to 6.6 Feet by 2100
Global sea level has risen about 8 inches (0.2 meters) since reliable record-keeping began in 1880. By 2100, scientists project that it will rise at least another foot (0.3 meters), but possibly as high as 6.6 feet (2 meters) in a high-emissions scenario. Sea level is rising because of added water from melting land ice and the expansion of seawater as it warms.
Hurricanes Will Become Stronger and More Intense
Scientists project that hurricane-associated storm intensity and rainfall rates will increase as the climate continues to warm.
More Droughts and Heat Waves
Droughts in the Southwest and heat waves (periods of abnormally hot weather lasting days to weeks) are projected to become more intense, and cold waves less intense and less frequent.
Longer Wildfire Season
Warming temperatures have extended and intensified wildfire season in the West, where long-term drought in the region has heightened the risk of fires. Scientists estimate that human-caused climate change has already doubled the area of forest burned in recent decades. By around 2050, the amount of land consumed by wildfires in Western states is projected to further increase by two to six times. Even in traditionally rainy regions like the Southeast, wildfires are projected to increase by about 30%.
Changes in Precipitation Patterns
Climate change is having an uneven effect on precipitation (rain and snow) in the United States, with some locations experiencing increased precipitation and flooding, while others suffer from drought. On average, more winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century.
Frost-Free Season (and Growing Season) will Lengthen
The length of the frost-free season, and the corresponding growing season, has been increasing since the 1980s, with the largest increases occurring in the western United States. Across the United States, the growing season is projected to continue to lengthen, which will affect ecosystems and agriculture.
Global Temperatures Will Continue to Rise
Summer of 2023 was Earth's hottest summer on record, 0.41 degrees Fahrenheit (F) (0.23 degrees Celsius (C)) warmer than any other summer in NASA’s record and 2.1 degrees F (1.2 C) warmer than the average summer between 1951 and 1980.
Arctic Is Very Likely to Become Ice-Free
Sea ice cover in the Arctic Ocean is expected to continue decreasing, and the Arctic Ocean will very likely become essentially ice-free in late summer if current projections hold. This change is expected to occur before mid-century.
There is no morality involved in Mikie's defense of the science, he's merely saying if you wanna be a self deceiving buffoon and deny the science, go right ahead, but all it takes is a quick 5 second search to return loads of neutral non biased science in support of climate change. — Vaskane

There, unequivocally, is not. — AmadeusD
You not understanding my moral/emotional reaction is absolutely no matter for this conflict of moral position. You don't understand my mental state here, and can't conceive of it without inferring psychopathy. — AmadeusD
That's factually inaccurate, as I am neither a psychopath nor do I have a strong stance in caring about climate change. Sorry. The facts are stacked against you conclusively on this. — AmadeusD
Assuming the person does care about others, they wouldn’t truly want to do nothing while the planet burns.
— Mikie
Hmm, again, that's just your position. — AmadeusD
No nihilism required. — AmadeusD
The eg of a child drowning is not at all correlative of the climate crisis. — AmadeusD
Again, it’s due to either ignorance or some kind of anti-social psychology.
— Mikie
It isn't, So there we are — AmadeusD
Which is why I suggest learning a little more about it rather than going with your feels.
— Mikie
That is exactly what you are doing. — AmadeusD
But Mikie, what of the thousands of German and Japanese children who died in WWII bombing campaigns? A horrible crime, right? — BitconnectCarlos
