Summary | Contemporary climate change includes both global warming caused by humans and its impacts on Earth's weather patterns. There have been previous periods of climate change, but the current changes are more rapid than any known events in Earth's history. The main cause is the emission of greenhouse gases, mostly carbon dioxide (CO2) and methane (CH4). Burning fossil fuels for energy use creates most of these emissions. | |

Contemporary climate change includes both global warming caused by humans and its impacts on Earth's weather patterns. There have been previous periods of climate change, but the current changes are more rapid than any known events in Earth's history. The main cause is the emission of greenhouse gases, mostly carbon dioxide (CO2) and methane (CH4). Burning fossil fuels for energy use creates most of these emissions. Agriculture, steel making, cement production, and forest loss are additional sources. Temperature rise is also affected by climate feedbacks such as the loss of sunlight-reflecting snow cover, and the release of carbon dioxide from drought-stricken forests. Collectively, these amplify global warming.
On land, temperatures have risen about twice as fast as the global average. Deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing more intense storms and other weather extremes. In places such as coral reefs, mountains, and the Arctic, many species are forced to relocate or become extinct, as their environment changes. Climate change threatens people with food and water scarcity, increased flooding, extreme heat, more disease, and economic loss. It can also drive human migration. The World Health Organization calls climate change the greatest threat to global health in the 21st century. Even if efforts to minimise future warming are successful, some effects will continue for centuries. These include sea level rise, and warmer, more acidic oceans.
Many of these impacts are already felt at the current level of warming, which is about 1.2 °C (2 °F). The Intergovernmental Panel on Climate Change (IPCC) projects even greater impacts as warming continues to 1.5 °C and beyond. Additional warming also increases the risk of triggering tipping points, such as the melting of the Greenland ice sheet. Responding to these changes involves taking actions to limit the amount of warming, and adapting to them. Future warming can be reduced (mitigated) by lowering greenhouse gas emissions and removing them from the atmosphere. This will involve using more wind and solar energy, phasing out coal, and increasing energy efficiency. Switching to electric vehicles, to public transport, and to heat pumps for homes and commercial buildings, could further limit emissions. Prevention of deforestation and enhancing forests can help absorb CO2. Some communities may adapt to climate change through better coastline protection, disaster management, and development of more resistant crops. By themselves, these efforts to adapt cannot avert the risk of severe, widespread and permanent impacts.
Under the 2015 Paris Agreement, nations collectively agreed to keep warming "well under 2.0°C (3.6°F)" through mitigation efforts. However, with pledges made under the Agreement, global warming would still reach about 2.8°C (5.0°F) by the end of the century. Limiting warming to 1.5°C (2.7°F) would require halving emissions by 2030 and achieving near-zero emissions by 2050.
Before the 1980s, it was unclear whether warming by greenhouse gases would dominate aerosol-induced cooling. Scientists then often used the term inadvertent climate modification to refer to the human impact on the climate. In the 1980s, the terms global warming and climate change were popularised. The former refers only to increased surface warming, the latter describes the full effect of greenhouse gases on the climate. Global warming became the most popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. In the 2000s, the term climate change increased in popularity. Global warming usually refers to human-induced warming of the Earth system, whereas climate change can refer to natural or anthropogenic change. The two terms are often used interchangeably.
Various scientists, politicians and media figures have adopted the terms climate crisis or climate emergency to talk about climate change, and global heating instead of global warming. The policy editor-in-chief of The Guardian said they included this language in their editorial guidelines "to ensure that we are being scientifically precise, while also communicating clearly with readers on this very important issue." In 2019, Oxford Languages chose climate emergency as its word of the year, defining it as "a situation in which urgent action is required to reduce or halt climate change and avoid potentially irreversible environmental damage resulting from it."

[JacobinMag.com, 2021-11-12] Rich People Are Destroying the Planet. Rich people have a carbon footprint 25 times the size of even the typical American. To tackle climate change, we need to start with fossil capital and the most affluent.
Last spring [2021-05-21], the Financial Times published a useful series of charts [Archive.today snapshot | local copy] showing the correlation between CO2 emissions [Greenhouse gas emissions] and the global distribution of wealth. The inequalities of the climate crisis are often, in many ways rightly, conceptualized as inequities between countries - particularly those of a few rich, carbon-intensive, industrialized economies and the rest.
But, as the Financial Times's data very clearly showed, there's actually a stark and highly visible divide between a tiny minority of extremely wealthy people and everyone else. Taken as a whole, those in the global top 1 percent of income account for 15 percent of emissions, which is more than double the share of those in the bottom half. The extremely wealthy have only gotten richer over the past thirty years and, as the data shows, their carbon footprints have gotten much bigger as well.
When this perspective is narrowed to individual countries, the class divide vis-à-vis carbon emissions is truly astonishing to behold. In the United States, those in the top decile of income alone account for half of household emissions while the bottom half account for under 10 percent. While America is admittedly a pretty extreme case, the same basic pattern holds true across many large industrialized economies - a point which underscores that the divides within countries are often at least as important as the divides between them.

[DemocracyNow.org, 2021-11-09] War Helps Fuel the Climate Crisis as U.S. Military Carbon Emissions Exceed 140+ Nations.
On Monday [2021-11-08], climate activists protested outside the 2021 United Nations Climate Change Conference (COP26) in Glasgow, Scotland - spotlighting the role of the U.S. military in fueling the climate crisis. The Costs of War Project estimates the military produced around 1.2 billion metric tons of carbon emissions between 2001 and 2017, with nearly a third coming from U.S. wars overseas. But military carbon emissions have largely been exempted from international climate treaties dating back to the 1997 Kyoto Protocol after lobbying from the United States. We go to Glasgow to speak with Ramón Mejía, anti-militarism national organizer of Grassroots Global Justice Alliance and Iraq War veteran; Erik Edstrom, Afghanistan War veteran turned climate activist; and Neta Crawford, director of the Costs of War project. "The United States military has been a mechanism of environmental destruction," says Crawford.

[CTVNews.ca, 2021-11-06] Canadians six times more likely to say climate change has negative impact on their health rather than positive: Nanos survey.
Canadians are six times more likely to report that climate change has a negative or somewhat negative impact on their day-to-day health rather than a positive impact, according to a new survey from Nanos Research.
The poll, conducted by Nanos Research and sponsored by CTV News, found that 41 per cent of Canadians surveyed would say climate change negatively or somewhat negatively impacts their health and 44 per cent of those surveyed said it has no impact on their health. Of those surveyed, six per cent said climate change has a positive or somewhat positive impact on their day-to-day health, while nine per cent of those surveyed were unsure.

[Straight.com, 2021-11-03] COP26: Why Justin Trudeau talks about a global carbon tax rather than production cuts that could save humanity. It's the latest incarnation of The "Big Stall, which was covered extensively in a 2018 book by Burnaby writer Donald Gutstein | Donald Gutstein's 2018 book, The Big Stall, explains why Big Oil prefers a carbon tax over measures that could actually stave off climate disaster.
Yesterday, I wrote a column exposing Prime Minister Justin Trudeau's hypocrisy in acting like a climate hero at the COP26 meetings in Glasgow. It obviously had little impact. That's because after the column appeared, the subservient media slavishly documented his efforts to promote a global carbon tax. Reporters covering COP26 have obviously not read Burnaby author Donald Gutstein's .
That's why they don't understand the game that Trudeau is playing. For https://en.wikipedia.org/wiki/Big_Oil, the goal is to avoid mandated production cuts at all costs. You'll hear Trudeau talk about an "emissions" cap on the industry but never a "production" cut. It fools the media. Press the Liberal government on how to achieve these so-called emissions cuts as the oil industry continues jacking up production, and the response is invariably "technology". Trudeau simply trusts Big Oil's pledge that it will work toward carbon neutrality.
Nowadays, the Big Stall is centred on suckering the media with fanciful stories about storing emissions underground. It's never been proven to come close to the scale necessary to prevent us all from being fried. Donald Gutstein's 2018 book revealed the Trudeau strategy in stark detail: go for a carbon tax, not production cuts. That's because with a carbon tax, the Canadian oil industry can continue ramping up the export of dirty, diluted bitumen. And that would keep money flowing into provincial and federal treasuries and prop up the Canadian dollar.
Don't get me wrong: a carbon tax is desirable. But it will never come close to saving our collective hides as long as Big Oil continues developing new fossil-fuel infrastructure, subsidized by Canadian taxpayers. Last year, Environmental Defence estimated that the Trudeau government subsidized and supported this industry to the tune of $18 billion. It's worth repeating: Big Oil prefers a carbon tax over production cuts.
So now, Trudeau is doing its bidding by advancing this idea internationally with one of his favourite phrases: "putting a price on pollution". It's been a masterful performance. I would like to say that history won't be kind to Trudeau for not urging a sharp decline in the production of oil and gas. But there won't be much of a history to document if this game of political charades ends up in societal breakdown and widespread famine.
