Climate change report urges immediate action

Climate change report urges immediate action

Very - the report calls for "rapid, far-reaching and unprecedented changes in all aspects of society". It has been reported, for instance, that the USA has been obstructionist in the deliberations in Incheon, South Korea, at the recent meeting to determine the final text of the report.

The report, which was authored by 91 scientists and review editors from 40 countries, cites over 6,000 scientific references, and represents the work of thousands of experts and government employees.

President Donald Trump acknowledged receiving an alarming report on climate change from the United Nations' Intergovernmental Panel on Climate Change Tuesday, at the same time saying "I want to look at who drew it". Coral reefs would decline by 70 percent to 90 percent with global warming of 1.5 degrees Celsius, whereas virtually all would be lost with 2 degrees Celsius. Trillions of dollars will soon be invested in new infrastructure; if we make the wrong choices, they'll be locked in, according to the same recent report.

Former Vice President Al Gore Jr. warned that "time is running out" after the release of a United Nations special report Sunday giving the world 12 years to head off climate calamity by radically transforming "all aspects of society".

According to the report, limiting global warming will require greener cities and more sustainable transportation industries.

The 1.5-degree scenario will require cutting Carbon dioxide emissions by as much as 45 percent over the 20-year period from 2010 to 2030 and to a net zero by 2050-net zero meaning that all Carbon dioxide released will need to be captured and stored or reused. Global CO2 emissions may need to peak around 2020.

Four scenarios are modeled in the report that reflect different strategies governments could take to deliver "no or low overshoot" of the 1.5°C target.

However, all methods "are at different stages of development and some are more conceptual than others, as they have not been tested at scale", the report warned. It would also cut down on species loss and extinction and reduce the impact on various ecosystems.

Fellow author Valerie Masson-Delmotte said: "The report shows that we are at a crossroads".

In any non-nightmarish scenario, world leaders would gather together upon receipt of this report, generated by highly respected scientists at the top of their game (the Intergovernmental Panel on Climate Change), and work overtime to solve the global and systemic problems stemming from overuse of dirty energy sources such as coal and the mass production of greenhouse gases, for two.

"This is one of the most important reports ever produced by the IPCC, and certainly one of the most needed", Hoesung Lee, the chair of the body, said at a press conference in South Korea on Monday. Previously, the threshold for serious damage was set at an increase of 3.6 degrees Fahrenheit, but that number has been edited as scientists have come to understand global warming.

It is critical that world leaders understand the IPCC report and use it as a template for immediate action. Instead, the Trump administration rejects the science of climate change and actively favors dirty energy sources over clean ones. India, as will the rest of the world, will continue to experience increasing negative impacts as the temperature rises, albeit much lesser than the calamitous effects of a 2°C warmer planet. Although the report says that emissions would not be the sole contributor to temperatures above 1.5°C, the future rates of emission reductions will determine whether temps rise.

Personal changes might include everything from eating less meat to using energy-efficient appliances and reducing air travel, said Patricia Pinho, a Brazilian climate scientist and report author.

So how can we make sure that warming does not exceed 1.5°C and take us into highly risky territory?
