Well, if we cannot control the weather, why do we keep pretending we can? Seems every story and many political campaigns are premised upon the fiction that we can control “climate change,” if we want.
Global Climate Changes

Natural increases in carbon dioxide concentrations have periodically warmed Earth’s temperature during ice age cycles over the past million years or more. The warm episodes (interglacials) began with a small increase in incoming sunlight in the Northern Hemisphere due to variations in Earth’s orbit around the Sun and its axis of rotation. (For more details, see the “Milankovitch cycles and ice ages” section of our Climate change: incoming sunlight article.) That little bit of extra sunlight caused a little bit of warming. As the oceans warmed, they outgassed carbon dioxide—like a can of soda going flat in the heat of a summer day. The extra carbon dioxide in the atmosphere greatly amplified the initial, solar-driven warming.
Based on air bubbles trapped in mile-thick ice cores and other paleoclimate evidence, we know that during the ice age cycles of the past million years or so, atmospheric carbon dioxide never exceeded 300 ppm. Before the Industrial Revolution started in the mid-1700s, atmospheric carbon dioxide was 280 ppm or less.
Atmospheric carbon dioxide (CO2) in parts per million (ppm) for the past 800,000 years based on ice-core data (light purple line) compared to 2022 concentration (bright purple dot). The peaks and valleys in the line show ice ages (low CO2) and warmer interglacials (higher CO2). Throughout that time, CO2 was never higher than 300 ppm (light purple dot, between 300,000 and 400,000 years ago). The increase over the last 60 years is 100 times faster than previous natural increases. In fact, on the geologic time scale, the increase from the end of the last ice age to the present (dashed purple line) looks virtually instantaneous. Graph by NOAA Climate.gov based on data from Lüthi, et al., 2008, via NOAA NCEI Paleoclimatology Program.
By the time continuous observations began at Mauna Loa Volcanic Observatory in 1958, global atmospheric carbon dioxide was already 315 ppm. Carbon dioxide levels today are higher than at any point in human history. In fact, the last time atmospheric carbon dioxide amounts were this high was roughly 3 million years ago, during the Mid-Pliocene Warm Period, when global surface temperature was 4.5–7.2 degrees Fahrenheit (2.5–4 degrees Celsius) warmer than during the pre-industrial era. Sea level was at least 16 feet higher than it was in 1900 and possibly as much as 82 feet higher.
If global energy demand continues to grow rapidly and we meet it mostly with fossil fuels, human emissions of carbon dioxide could reach 75 billion tons per year or more by the end of the century. Atmospheric carbon dioxide could be 800 ppm or higher—conditions not seen on Earth for close to 50 million years.

France runs fusion reactor for record 22 minutes
France has upped the ante in the quest for fusion power by maintaining a plasma reaction for over 22 minutes – a new record. The milestone was reached on February 12 at the Commissariat à l'énergie atomique et aux énergies alternatives (CEA) WEST Tokamak reactor.

Oil and gas companies are influencing what Canadian students learn about climate change, funding and supplying educational materials that frame the issue to serve their interests, health and climate advocates warn in a new report.
At least 39 fossil fuel companies and 12 industry-linked organizations – including Shell, TC Energy, and the Pathways Alliance – have supplied classroom resources that downplay the sector’s role in driving global heating, states a new report. The materials emphasize consumer responsibility and technological solutions, while largely omitting the need for a rapid transition away from fossil fuels.
Published by the Canadian Association of Physicians for the Environment (CAPE) and the parent-led advocacy group For Our Kids, the Polluting Education report argues that industry-backed materials present a distorted picture to students, steering them toward false solutions.
Énergir, for example, has sponsored a Quebec school program since 2016, encouraging children and families to “commit to reducing their carbon footprint and then sell their reductions to other participants as carbon credits.”

Industry-backed perspectives on climate change
Through direct contact with schools, government partnerships, and funding for third-party education, oil and gas interests like Shell, Imperial Oil, and Cenovus have a heavy influence on what Canadian kids learn, the report authors say.Énergir, for example, has sponsored a Quebec school program since 2016, encouraging children and families to “commit to reducing their carbon footprint and then sell their reductions to other participants as carbon credits.”

Nuclear is the correct answer.

Scientists scorn EPA push to say climate change isn't a danger, say just look around at the world
As President Donald Trump's administration looks to reverse a cornerstone finding that climate change endangers human health and welfare, scientists say they need to look around because it’s obvious how bad global warming is and how its getting worse.
apnews.com
Scientists said the Trump administration will be hard-pressed to find scientific justification — or legitimate scientists — to show how greenhouse gases are not a threat to people.
“This one of those cases where they can’t contest the science and they’re going to have a legal way around,” Princeton University climate scientist Michael Oppenheimer said.

There is no possible world in which greenhouse gases are not a threat to public health,” said Brown University climate scientist Kim Cobb. “It’s simple physics coming up against simple physiology and biology, and the limits of our existing infrastructure to protect us against worsening climate-fueled extremes.”
Who I am pretty much 1000% sure has to get federal funding to continue to "prove" their stance. So yeah, I am sure she wholeheartedly believes what she's saying but she is also very motivated to get funding as a part of her goal to prove something that really doesn't exist.
Interesting article claims that 36 companies are responsible for half of the world's carbon emissions. Very few US companies are on the list and in none of the top ten spots. The big emmiters are Chinese, Russian, Indian and Middle East energy companies. We aren't the problem even though we have the world's largest economy.

The 36 companies responsible for HALF the world's carbon emissions
Just 36 of the world's richest and most powerful companies are responsible for more than half of the world's greenhouse gas production, according to a new report.

Pretty much sums up all of my concerns using facts and proven propaganda. I assume the believers like GJNorman just assume that the folks that get paid out the ass are telling the truth though. I would like one of them to watch the video and give me an honest take on why they would still believe in the global hoax.
