Global Temperature To Rise By 1.5 Degree Celsius Between 2030 And 2052


Global Temperature To Rise By 1.5 Degree Celsius Between 2030 And 2052

Impacts of climate change, from droughts to rising seas, will be less extreme if temperature rises are curbed at 1.5C above pre-industrial levels than if they climb to 2C, the UN-backed study said.

Neither Premier Ford nor Mr. Kenney have yet said what policies they would employ to cut emissions, or whether they support Canada's objective of reducing greenhouse gas emissions by 30 per cent below 2005 levels by 2030 - a commitment made under the Paris accord.

The 2015 Paris Agreement sets a goal to cap the increase in the global average temperature to below 2 degrees above pre-industrial levels.

An Associated Press article poignantly captures what the IPCC said in its "gloomy" report: That "preventing an extra single degree of heat" - meaning the 2 degrees C mark - "could make a life-or-death difference in the next few decades for multitudes of people and ecosystems on this fast-warming planet".

The world is experiencing around 1C of warming and floods, storms and heat waves like the one experienced by the United Kingdom this summer have become increasingly likely as a result of climate change, according to experts.

Countries must take "unprecedented" action to slash carbon emissions to zero by 2050 and limit unsafe global warming, a key report warns.

Jim Skea, who worked on the report, said: "Limiting warming to 1.5C is possible within the laws of chemistry and physics but doing so would require unprecedented changes".

The report stated that allowing the global temperature to "overshoot" 1.5 degrees would mean a greater reliance on removing carbon dioxide from the air.

The IPCC accepted the invitation, adding that the Special Report would look at these issues in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.

Dr. Michiel Schaeffer, director of science, said: "The IPCC confirms that it is feasible to hold warming to 1.5°, or very close to it, throughout the 21st Century, but that there is no time for complacency".

Temperatures during summer heatwaves, such as those just experienced across Europe this summer, can be expected to increase by 3 degrees C says the report.

The US delegation - the first since Donald Trump took office to work on an IPCC report - did not throw a monkey wrench into the process, as many here had feared.

Coral reefs would decline by 70 to 90 percent with global warming of 1.5 C, whereas virtually all, over 99 percent, would be lost with 2 C.

The report goes on to conclude that the global economy would effectively need to "stop on a dime" to deal with the impacts of climate change in time to reverse them, Freedman said.

The report underlines how even the smallest increase in the base target would worsen the impact of recent natural disasters. However, limiting the global temperature rise to 1.5℃ as opposed to 2℃ can help in reducing poverty as well as reduce losses in yields of maize, rice, wheat and other cereal crops, mainly in Asia.

Coral reefs would decline by 70% to 90% instead of being nearly completely wiped out.

President Trump announced in June he would pull out of the Paris accord, saying it would put the USA economy at a global disadvantage.

"The good news is that some of the kinds of actions that would be needed to limit global warming to 1.5 °C are already underway around the world, but they would need to accelerate", said Valerie Masson-Delmotte, Co-Chair of Working Group I.

But meeting the more ambitious goal of slightly less warming would require immediate, draconian cuts in emissions of heat-trapping gases and dramatic changes in the energy field.

In order stop climate change from reaching unsafe levels, it is necessary to reduce worldwide emissions whilst at the same time removing Carbon dioxide out of the atmosphere. Industries and investors need to be bold and far-sighted, for example by cutting all links to fossil fuels and supporting a carbon price.

Responding to the report, Prof Corinne Le Quere, from the University of East Anglia, said: "For the United Kingdom, this means a rapid switch to renewable energy and electric cars, insulating our homes, planting trees, where possible walking or cycling and eating well - more plants and less meat - and developing an industry to capture carbon and store it underground".
