IPCC report: Charts detail climate change

[ad_1]

The problem of climate change is not caused by one person and will never be solved with one solution. Climate change is a result of a multitude of factors and will be addressed with a variety of adaptation and mitigation strategies.

There has been significant progress on the global level to reduce greenhouse gas emissions and slow down global warming. But it’s not enough.

This is a complex story, and charts are included in the latest Intergovernmental Panel on Climate Change report which was published MondayVisual storytelling can help you tell your story.

Although the solutions and factors are incremental in nature, they have clear and dire consequences if we fail to act.

“We are on a fast track to climate disaster: Major cities under water. Inexpensive heatwaves. Terrifying storms. Water shortages are widespread. A million animals and plants could be extinct. It isn’t fiction. Science tells me that this is what our current energy policy will produce.” United Nations Secretary General António Guterres said on MondayIn response to the report.

Humans have been increasing greenhouse gas emissions

Over the past few decades, anthropogenic greenhouse gas emissions (originating from human activities) have increased.

Intergovernmental Panel on Climate Change, (IPCC).

Climate change has become a serious problem due to global anthropogenic greenhouse gas emissions, which are derived from human activity. Considered as a whole. emissions reductions from efficienciesCompared to rising global activities, they have been lower than the emissions increase.

In order to limit global warming to around 1.5° Celsius (2.7° Farenheiht) above pre-industrial levels, which is the generally accepted goal established by the 2015 Paris Climate AgreementAccording to the IPCC’s analysis, greenhouse gas emissions must reach their maximum peak by 2025. According to the IPCC report, greenhouse gas emissions need to be cut by 43% by 2030. 278 scientists and experts.

But that’s not the direction where the world currently is headed. Guterres stated Monday that current climate promises would result in a 14% increase of emissions. “And many major emitters aren’t taking the steps necessary to fulfil even these inadequacies.” 

True, however, is that it also holds true for the rate of growth of greenhouse gas emissionsThe difference between 2010-2019 was smaller than between 2000-9999.

Renewable energy costs have plunged

Costs of renewable energy and their adoption.

Intergovernmental Panel on Climate Change, (IPCC).

In the past decade, the prices of solar and wind energy have fallen precipitously due to their rapid development and scale-up. These technologies are being adopted more and more.

But, it is essential that the rate of transition to renewable energy be tripled. Guterres said on MondayIn response to the report. He stated that renewables were already much cheaper in most cases.

Countries around the globe have been forced to reduce their dependency on Russian energy by the war in Ukraine. The result was that leaders including those U.S. Secretary of Energy Jennifer GranholmThey called for an increase domestic oil production and lower prices to satisfy wartime demand.

But, even a temporary increase in oil production was rebuffed by the UN secretary-general.

“Inflation has risen and war in Ukraine caused energy and food prices to soar. Guterres claimed Monday that the increase in fossil fuel production would only worsen matters. “The commitment to 1.5°C will not be fulfilled if countries don’t make the right choices now.” 

Climate action in the current climate is inadequate

For different policy approaches, projected greenhouse gas emission.

Global response to climate changes is inadequate at the moment.

Even if national contributions are made before the COP26 climate conference, global warming will still not be controlled by greenhouse gas emissions.

As you can see, the current trend in policies implemented is shown in red. The light blue and green lines show greenhouse gas emissions that would be necessary to limit global warming to 1.5° Celsius and 2° Celsius, respectively. The red trend line indicates where the globe is currently heading. Both trend lines lie below it.

Limiting global warming requires more drastic reductions

Intergovernmental Panel on Climate Change, (IPCC).

Global warming (shown to the right) is dependent on how aggressively we reduce our emissions.

The lessening of global warming will be achieved by a more aggressive policy (C1), which uses a lighter color. Global warming will be greatest if there is a less aggressive policy to reduce emissions (C8), which is dark red.

It is urgent to take action on pathways that will limit global warming by 1.5 and 2 degrees Celsius.

It is urgent to take action on mitigation pathways that reduce global warming by 1.5- or 2-degree Celsius.

It chart above shows greenhouse gas (GHG), carbon dioxide (CO2) methane (CH4) and nitrous oxide (N2O) emissions under various potential scenarios, what the IPCC calls illustrative mitigation emissions pathways (IMPs).

The red-shaded ranges show the projected emissions pathwaysIf existing policies and promises are maintained. The blue shaded range show emissions pathways if more aggressive policies that limit global warming to 1.5°C are implemented.

“It’s now or never, if we want to limit global warming to 1.5°C (2.7°F),” said Skea in a written statement. “It will not happen without immediate, deep emission reductions in all sector sectors.

Consumer behavior changes can lower demand

Changes in the demand for electricity, food and manufactured products could have a significant impact on climate change mitigation. This can be done by infrastructure adaptations and behavioral adaptions.

Intergovernmental Panel on Climate Change, (IPCC).

The key ingredient to reducing greenhouse gas emissions is limiting demandIPCC has broken down the change into three distinct types. Individuals make choices about their behavior through socio-cultural factors. Changes in infrastructure design that enable individuals to make alternative choices are called “Infrastructure usage”. Changes in technology use by end-users are called “end-use tech adoption”.

The right infrastructure, policies and technology can help to reduce greenhouse gas emissions from 40-70% by 2050 if there are the right policies in place. “This has significant untapped potential,” Priyadarshi Shikla, co-chair of IPCC Working Group III, said in a written statement. These lifestyle modifications can also improve our overall health and well-being, according to evidence.

People who can easily walk or only travel short distances between cities have the option of leaving a smaller carbon footprint.

Additionally, efficiency will be a key factor in building design. Skea said, “We have examples of zero-energy and zero-carbon buildings in nearly all climates.” Skea stated, “It is crucial to take action in the next decade to harness the mitigation potential for buildings.”
