Climate Change Update - Here and Now




The International Panel on Climate Change has been telling us for decades that we can expect extreme weather events.

Well, the extreme weather events are here! See for yourself.

And here is what happened in just one month; July 2021. Take a look.

These catastrophic weather events have occurred with just 1.1 Deg. C warming. Because there is so much Carbon Dioxide in our atmosphere; even if we went to zero carbon emissions today, global warming will continue to increase. It will bring with it increased severity of weather events.

Reducing our carbon emissions by 50% by 2030 is critical if we are to avoid irreversible climate change.

What we Know – The Climate Emergency.

In December 2015, the United Nations Framework Convention on Climate Change (UNFCC) held 21st Conference of the Parties in Paris (COP21). 196 countries agreed to limit global warming to well below 2, preferably to 1.5 degrees Celsius, compared to pre-industrial levels.

Unfortunately, the carbon emission reductions submitted by nations were far short to achieve this objective. However, it was agreed that nations would submit new emission reduction targets along with their plans to reduce emissions by 50% by 2030 and 100% by 2050 at COP 26 in November 2021.

During this time, more research revealed the existence of imminent risks that could tip the climate into irreversible climate change. There are a few Tipping Points, but the thawing of the Tundra, releasing billions of tonnes of methane into our atmosphere is very concerning and has already started.

There seemed little action for the Paris goals until 2018 when the International Panel on Climate Change (IPCC) released its Special 1.5 deg. Report.

The report effectively launched the Climate Emergency by outlining the catastrophic consequences of exceeding 1.5 deg. global warming, together with the deadline of reducing carbon emissions by 50% by 2030 and 100% by 2050. Many large businesses sprang into action, but most governments were still reluctant to move.

Government inaction changed significantly when the IPCC released the Sixth Assessment Report (Ar6) in August 2021.

Governments and businesses around the world realised their imminent risks and catastrophic consequences of exceeding 1.5 deg. C warming.

It is not all bad news. Read the blog in the following week to see how we can avoid irreversible climate change.
