United Nations report warns of possible climate disaster by 2040

United Nations report warns of possible climate disaster by 2040

"Countries like India, with large populations dependent on the agricultural and fishery sectors, would be highly impacted", he said.

But the agreement's more ambitious goal was to prevent temperatures from rising more than 1.5 degrees C. That's because even 1.5 degrees of warming will cause catastrophic effects, including more intense storms, searing heat waves, mass extinctions, and droughts.

It will be one of the main items discussed at a global conference in Poland in December, when governments will review the Paris Agreement (which the USA withdrew from in June 2017).

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. These heat-trapping gases are the byproduct of industrial processes such as refrigeration and can be eliminated from those processes by re-engineering.

US President Donald Trump said he has yet to read a United Nations report warning of global warming-caused chaos unless drastic action is taken and added that he is sceptical.

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 Summary for Policymakers (SPM) presents the key findings of the Special Report, based on the assessment of the available scientific, technical and socio-economic literature relevant to global warming of 1.5 °C.

Action in cities - which consume more than two-thirds of energy globally and account for about three-quarters of carbon emissions - are pivotal to meeting the target, said report author William Solecki, a professor at Hunter College-City University of NY.

Google exposed personal data of nearly 500,000 and didn't disclose it
Google says that like other tech companies, it has encouraged third-party developers to "build on top of our various services". The WSJ quoted an internal Google memo that said doing so would draw " immediate regulatory interest ".

This means that any remaining emissions would need to be balanced by removing Carbon dioxide from the air.

Yesterday, the United Nations released a terrifying report about climate change, which basically said we've got around 12 years left to keep climate change to a minimum.

He said the difference between a 1.5ºC rise and a 2ºC rise would have a particularly harsh effect on the mean temperature and rainfall in Southern Africa, which is a "hot spot because it is semi-arid and is water-stressed". With a 2°C rise, the impacts can be too serious for communities to adapt. "Even the scientists were surprised to see how much science was already there and how much they could really differentiate and how great are the benefits of limiting global warming at 1.5 compared to 2", Thelma Krug, vice-chair of the IPCC, told Reuters.

To contain warming at 1.5C, man-made global net carbon dioxide (CO2) emissions would need to fall by about 45 percent by 2030 from 2010 levels and reach "net zero" by mid-century.

Approved by the IPCC in South Korea on Saturday ahead of COP24 in Poland in December, Global Warming of 1.5°C was produced by 91 authors and reviewers from 40 countries. It would also cut down on species loss and extinction and reduce the impact on various ecosystems.

The world needs to make decisions now for the future.

Professor Piers Forster, a leading author of the report who lectures at the University of Leeds, said current policies put the world on course for a "super-risky 3C of warming", adding: 'The report shows that limiting warming to 1.5C is barely feasible and, every year we delay, the window of feasibility halves. The most-affected areas in India will be mega cities, coastal areas, high-mountain and small-island regions. "The only way to achieve it is to stop all fossil fuel extraction and redirect the massive resources now spent on the fossil fuel economy towards the renewable energy transition".

Limiting the increase to 1.5 degrees would also have a dramatic impact on economic growth and development in poorer countries, which could reduce the number of people both exposed to climate-related risks and susceptible to poverty by several hundred million by 2050, it said. Otherwise, the world will probably begin seeing massive droughts, floods, and food shortages by 2040.
