Scottish Government to seek new advice on climate change targets

But most governments now fear the cost of a global overhaul of the world's energy economy in the short time needed to meet the Paris climate goals. Limiting global warming to less than 2ºC will hopefully allow ecosystems and animals to adapt to the gradually rising temperatures.

The IPCC, the UN's top climate panel, issued the report from Incheon, Republic of Korea, where for the past week, hundreds of scientists and government representatives have been pouring over thousands of inputs to paint a picture of what could happen to the planet and its inhabitants with global warming of 1.5°C (or 2.7 degrees Fahrenheit).

One of the report's authors noted that limiting warming to 1.5ºC is possible within the laws of chemistry and physics, but that doing so "would require unprecedented changes". "It really reduces the impacts of climate change in very important ways", said Prof Jim Skea, who is a co-chair of the IPCC.

Tweeting shortly after the report was launched UN Secretary-General António Guterres said that it is not impossible to limit global warming to 1.5°C, according to the report.

According to a report released by Britain-based Christian Aid, coastal cities like London, Houston, Jakarta and Shanghai are set to become extremely vulnerable to storm surges and flooding.

While much has been said about the need to limit global warming temperatures - what exactly is the difference between 2C and 1.5C and how does it impact the world?

However, that changed in 2017 with a 1.4 per cent increase in emissions from China.

"Countries like India, with large populations dependent on the agricultural and fishery sectors, would be highly impacted", he said. In order to limit the increase to 1.5°C, the models predict that a 45 percent decline in Carbon dioxide emissions is necessary from 2010 levels by 2030.

Another recent report from the consulting firm PwC makes it clear that even limiting warming to 2 degrees C will be a stretch: "There seems to be nearly zero chance of limiting warming to well below two degrees (the main goal of the Paris Agreement), though widespread use of carbon capture and storage technologies, including Natural Climate Solutions, may make this possible", it says.

They're calling for "rapid, far-reaching and unprecedented changes" across society to prevent world temperatures from rising by two degrees Celsius. Among them, sea level rises would be around 48cm if the temperature was 1.5C and 56cm for 2C. However, the damage is already done in so many fragile ecologies. The likelihood of an Arctic Ocean free of sea ice in summer would be once per century with global warming of 1.5°C, compared with at least once per decade with 2°C.

This means that weaning off coal and fossil fuels could not only help reduce carbon emissions and help limit the global temperature rise but also result in economic benefits. We also will need to rely on carbon removal-whether that's as low-tech as planting trees or using new technology like direct air capture that can suck CO2 from the atmosphere. We are displaying global leadership for all humankind. "We have to act, and we're a short time-frame to do so before we lose the ability to turn things around", Solheim told IANS in a recent interview.

A new United Nations report has warned that unprecedented changes across all aspects of society are needed in order to limit unsafe global warming.

The impact of 1.5 degrees Celsius warming is greater than what was anticipated earlier while the impacts at two degrees Celsius are "catastrophic" for the poor and for developing nations such as India, the Centre for Science and Environment (CSE) said.

One gigatonne is roughly equivalent to one year of transport emissions in the European Union, including aviation.
