Climate Change and Idai

Cyclone Idai is one of many extreme weather events.

Storms on this scale are not a new thing. But we have to expect more storms of increased severity as the planet heats up.

One of the main drivers of weather is transfers of energy between the atmosphere and the oceans.

One of the lesser-known facts about climate change is that 90% of the extra energy being captured by greenhouse gases is in the oceans.

While warming of the surface is alarming that is, so as to speak, only the tip of the iceberg.

Here in South Africa, we see a limited effect – the temporary loss of electricity from Mozambique’s Cahora Bassa hydroelectric power plant. But for our neighbours, this is a massive calamity.

Can we still stand by quietly while the forces of fossil fuel propel our planet towards the risk of a major extinction event?

The risk is not theoretical and distant – it is real and on our own doorstep, with major impacts not only in Mozambique but in Malawi and Zimbabwe.

So why is climate change not a big issue in the 2019 South African elections? Instead, we hear a ramping up of xenophobic rhetoric – and that is before we have a significant number of climate refugees caused in part by our own addiction to fossil fuels.

  1. Its above the oceans that the two main green house gases form, these are water vapor and clouds! There is a lot of propaganda about CO2 being a “ polluter” but it is the building block of all life on earth. Humans excell CO2 ( plus water, hidrogĂ©nio and oxigen)! CO2 Saturates in the atmosphere and no matter how much you add, levels remain pretty much constant. Climate change is a natural fenomena but climate disruption is due to planetary geoengineering programs, the elephant in the room. And make no mistake, anthropogenic aerosols, the “new species of clouds” are by no means a product of combustion but a product of the deliberate dispersing of particulates in the atmosphere. Co2 seems to interfere with this technology and for that reason needs to be captured, demonized...And of course the carbon Tax will fill the policy makers pockets. It is immoral to deny poor countries to explore their resources and coal, etc is now being demonized. Meantime uranium mines in SA are the biggest polluters. A power plant breath is identical to your breath. Greenpeace is posting photos of coal cooling towers releasing black smoke when they should only release water vapor...Greempeace is totally subject to power and so is the mainstream media and alternative media... Children are now used to further the powers that should not be agendas...The world and humanity are indeed in danger!

  2. 1. Every climate scientist knows about water vapour and clouds; they are factored into the models and nothing is driving an increase in either other than warming caused by CO_2.

    2. Your claim about aerosols is weird. This is also a known phenomenon and mostly reduces warming; there is no evidence that the effect on clouds is a significant impact on climate.

    3. It is bunk that CO_2 “saturates”. In the far distant past, CO_2 levels were many times higher than today. CO_2 is a long-lived gas, meaning it does not have a mechanism like precipitating out to reduce its content; once short-term processes like dissolution in the oceans are exhausted, much slower process like weathering remove the remaining excess on a time-scale too long to matter to humans. CO_2 levels have been increasing steadily over the industrial age.

    The claims you make have been debunked many times over. There is one lobby that overwhelmingly attacks climate science: fossil fuels and their allies. They stand to lose massively if action is taken. That is the only conspiracy and it is in plain sight.
