Why farmers are forcing climate change into the spotlight

11 October 2018

The climate change taking place around us is a sign that it's high time to work collectively to Earth from being polluted.

If global emissions continue as per the commitments made under Paris Agreement, the carbon budget (the amount of CO2 that the world can emit) for 1.5°C warming will be exhausted by 2030, the CSE said referring to the report. You know, which group drew it.

Where Has The Warning Come From?

But to do that, the UN's Intergovernmental Panel on Climate Change (IPCC) says, would require "rapid, far-reaching and unprecedented changes in all aspects of society".

Is It A Big Deal?

Society would have to enact "unprecedented" changes to how it consumes energy, travels and builds to meet a lower global warming target or it risks increases in heat waves, flood-causing storms and the chances of drought in some regions as well as the loss of species, a United Nations report said on Monday.

The special report was requested by 195 nations when they adopted the Paris Agreement in December 2015 at the 21st Conference of the Parties (COP21) to the UNFCCC. "The next few years are probably the most important in our history, ' she said", as cited in the IPCC press release in question.

Trump talks up second North Korea summit
This version of the story corrects 4th paragraph to make clear that Washington has been seeking inspection of Yongbyon. Pompeo, however, played down the differences. "I would certainly expect so", the official said.

How Can Cuts Be Achieved?

Temperatures have already risen an average 1C since the mid-1800s as industrialisation fuels the growth of carbon dioxide emissions (CO2), the main greenhouse gas blamed for climate change.

"International cooperation is absolutely imperative to limit emissions and therefore global warming and its impacts, as well as coordinating effective and widespread adaptation and mitigation", said Sarah Perkins-Kirkpatrick, a fellow at the Climate Change Research Center at the University of New South Wales.

Currently, the world has seen 1C of warming over the past 115 years, according to a United States report last year. More worrying estimates include a complete meltdown of the Greenland ice sheet, and rising sea levels that would be enough to submerge London, National Geographic reported. Global sea levels rose 17cm in the 20th century.

If no immediate action is taken to control global warming beyond the1.5ºC increase, sea levels across the world might rise to 10cm.

While coral reefs could decline 70% to 90% with 1.5C of warming, virtually all the world's reefs would be lost at 2C, while far more creatures and plants across the world face losing a large part of their range.

Clearly, that deceivingly small half-degree difference has the potential to bring about significantly worse effects.

Kanye West Meets with Trump at White House
He also shared his dream of seeing Trump and Colin Kaepernick together at the Super Bowl , both wearing MAGA hats. He said he "loves" the president, before hugging him. "I love Hillary .

"We are still going to see many challenges at 1.5°C".

What Has Been The Reaction So Far?

Limiting warming to 1.5°C is possible within the laws of chemistry and physics but doing so would require unprecedented changes, Co-Chair of IPCC Working Group III Jim Skea said. We can't find any historical analogies for it.

The report warns the world is set to breach the 1.5C threshold by around 2040 and is heading for 3C by 2100 and even warmer after that.

"Climate activists have been calling for decades for leaders to show responsibility and take urgent action, but we have barely scratched the surface of what needs to be done".

"It also means adapting to the growing impacts of climate change that are felt here, particularly to the increasing flood risks from heavy rainfall and from sea level rise along our coasts".

Pre-industrial levels refers to the climate before the industrial revolution when greenhouse gas emissions were stable.

Advisers had also cautioned Trump against doing anything dramatic in the weeks before the midterm elections next month. As he left the White House for Orlando, Trump was asked by a reporter if he had any plans to fire Rosenstein.
