Thousands of & # 39; the world's greatest scientists have united to declare that & # 39; immeasurable human suffering & # 39; is inevitable without profound and lasting changes in human activities.
An alliance of more than 11,000 scientists signed the newspaper explaining the climate emergency before providing a series of effective measures that people could take to limit the damage caused by their greenhouse gas emissions.
The global group is led by William J. Ripple professor of ecology at Oregon State University and researcher Christopher Wolf.
Professor Ripple said: “Despite 40 years of major global negotiations, we have continued to do business and have not addressed this crisis.
& # 39; Climate change has arrived and is accelerating faster than many scientists had expected. & # 39;

The article pointed to six areas in which humanity should take immediate steps to delay the effects of a warming planet.
Firstly, reducing energy consumption and replacing fossil fuels with low-carbon renewable energy sources – leaving remaining fossil fuel stocks in the ground.
They describe how this can be encouraged by scrapping subsidies to fossil fuel companies and imposing carbon taxes high enough to limit the use of fossil fuels.
Secondly, the newspaper called for the reduction of & # 39; short-lived pollutants & # 39; drastically reduce methane, soot and fluorocarbons – calculating that the reduction could reduce the warming trend by 50 percent in the short term in the coming decades.

The article also suggests that ecosystems such as forests, grasslands and mangroves are protected to & # 39; ecological potential & # 39; and act as carbon dioxide converters – a common greenhouse gas created by human activity.
People are encouraged by the researchers to follow a diet with fewer animal products.
The food shift would significantly reduce methane and other greenhouse gas emissions and free up agricultural land for growing human food instead of feed.
Reducing food wastage is also considered crucial – the scientists say that at least one third of all food produced is disposed of as waste, meaning that unnecessary emissions have occurred during its production.
Scientists argue for a & # 39; carbon-free & # 39; economy, shifting goals from the growth of gross domestic product and the pursuit of extreme wealth.
Instead, people would increase their & # 39; biosphere dependence & # 39; must realize and put them first, according to the newspaper, which limits the exploitation of ecosystems.

Finally, the paper states that the rate of growth of the human population, which is increasing by more than 200,000 people per day, must be slowed in order to maintain an ecologically healthy world.
They add that population control should be approached with methods that ensure social and economic justice.
The paper was published today in BioScience and contained more than 11,000 signatories of science articles from 153 countries.
In conclusion, the article states: & Limiting and adapting to climate change and at the same time respecting human diversity entails major changes in the way our global society functions and works with natural ecosystems.
& # 39; We are encouraged by a recent peak of concern. Government agencies make climate statements. School children stand out. Ecocide lawsuits are ongoing in the courts. Movements of citizens on the basis of change demand change, and many countries, states and provinces, cities and companies respond to this.
& # 39; As an Alliance of World Scientists, we are ready to help decision-makers make a fair transition to a sustainable and equitable future. & # 39;
In recent decades, several other global assemblies have agreed that urgent action is essential, but greenhouse gas emissions are still increasing rapidly
Graphs of vital functions in the paper illustrate various important indicators and factors for climate change over the past 40 years, as scientists from 50 countries met at the First World Climate Conference in Geneva in 1979.
In recent decades, several other global assemblies have agreed that urgent action is essential, but greenhouse gas emissions are still increasing rapidly.
Other ominous signs of human activity include continued increase in meat production per capita, global loss of tree cover and number of airline passengers.
There are also some encouraging signs – including declines in global birth rates and delayed forest loss in the Brazilian Amazon and increased wind and solar energy – but even those measures have been taken with care.
For example, the fall in the birth rate has slowed over the last 20 years and the rate of loss of the Amazon forest seems to be rising again.
Professor Ripple added: Global surface temperature, ocean heat, extreme weather and costs, sea level, oceanic acidity, and burnt areas in the United States are all rising.
& # 39; Worldwide ice disappears quickly, as evidenced by the decrease in the minimum summer ice in the North Pole, Greenland and Antarctic ice sheets and the thickness of the glacier. All these rapid changes underline the urgent need for action. & # 39;
WHAT STEPS CAN WE TAKE TO LIMIT CLIMATE CHANGE?
Steps detailed in the article written by William J. Ripple professor of ecology at Oregon State University and researcher Christopher Wolf.
- Implement mass preservation methods
- Replace fossil fuels with low-carbon renewable energy sources
- Leave residual stocks of fossil fuels in the ground
- Abolish subsidies to fossil fuel companies
- Impose CO2 allowances that are high enough to limit the use of fossil fuels
2) ShoRT lived pollutants
Quickly reduce methane, soot, hydrofluorocarbons, and other short-lived climate pollutants – this can reduce the short-term warming trend by more than 50% in the coming decades.
Restore and protect ecosystems such as forests, grasslands, peatlands, wetlands and mangroves, and allow a larger proportion of these ecosystems to reach their ecological potential for storing atmospheric carbon dioxide, an important greenhouse gas.
- Eat more plants and consume fewer animal products. The food shift would significantly reduce methane and other greenhouse gas emissions and free up agricultural land for growing human food instead of feed.
- Reducing food waste is also crucial – the scientists say that at least one third of all food produced ends up as waste.
Turn the economy into a carbon-free one to tackle human dependence on the biosphere and shift goals from the growth of gross domestic product and the pursuit of wealth. Fighting ecosystems to maintain the long-term sustainability of the biosphere.
Stabilize a global human population that is growing by more than 200,000 people a day, using approaches that ensure social and economic justice.
