Cement is an understated source of climate change in the public view. It’s remarkable the portion it contributes on its own.Methane byproduct mostly and of course all that concrete.

I'm confused why you think that, am I missing something? Everything I've ever read says we've cut down approximately 50% of trees worldwide since the start of human civilisation?Funny thing is that we never had as many trees than now in the whole human history
Genuinely I didn't want to antagonize anyone on that. I always read the oppositeI'm confused why you think that, am I missing something? Everything I've ever read says we've cut down approximately 50% of trees worldwide since the start of human civilisation?
There are more trees than originally estimated, but we've still halved the total really quickly.

That's interesting, I never knew that the trees in the Amazon being cut were being covered by trees growing in areas that couldn't sustain them before because of global warming!Genuinely I didn't want to antagonize anyone on that. I always read the opposite
I have kids, and they are becoming ever more aware of the shit show they are going to inherit. So for their sake I can't accept it. There are things that can mitigate co 2 emissions and it's up to us to create the political pressure to get them done.Funny thing is that we never had as many trees than now in the whole human history. Lack of trees are not the main problem (in terms of regenerating CO2 to O2. Killing ecosystem is another matter though). Nuclear energy would be the fastest way to cut emissions despite the risk and waiting for the fusion as the only solution. Anyway there is many other things like aviation (will not be solved in 30 years) that will keep increasing) and mostly meat consumption and specially, human birth rate
Oh, and we are fecked, accept it
Well,I don't accept it and neither should you. I have kids, and they are becoming ever more aware of the shit show they are going to inherit. So for their sake I can't accept it. There are things that can mitigate co 2 emissions and it's up to us to create the political pressure to get them done.
Yup, las t link didnt read it to be honest, I wanted to overwhelmed you with quantity. Why you even open it, since when people goes further than the first lineThat's interesting, I never knew that the trees in the Amazon being cut were being covered by trees growing in areas that couldn't sustain them before because of global warming!
I think the last link is a bit disingenuous though. It talks about trees going from 1 trillion to 3 trillion, but that was actually due to estimates being below reality and satellites being better able to count tree cover as mentioned in my article. That one also suggests that overall tree cover is going down.
There's obviously more to it than I thought though.
To be fair, there's a fairly massive difference between "human history" and 37 years. The last link claims to fact check a claim that we have more trees than 100 years ago, but it doesn't actually ever answer the question. There might be more trees now than a hundred years ago, but I bet not much further back than that.Genuinely I didn't want to antagonize anyone on that. I always read the opposite

That is not true. more than 100 years ago, american forest were barely touched, specially the ones in latinamericaTo be fair, there's a fairly massive difference between "human history" and 37 years.

Seems like you're arguing against your own point here, though?That is not true. more than 100 years ago, american forest were barely touched, specially the ones in latinamerica
A low point in Europe, sure.Wood was massively used during the medieval age causing a low point on forest levels. I am just talking about on memory about a graphic that I saw a looong time. I will try to find it
This is true for the UK, and some other European countries, but I doubt it's true for most of the world. We're definitely on our way up, though.I proof myslef wrong. Wasn't the medieval age.
But for example, UK, if the graph is true, the forestry percentage cover never been better in the past 700 years
Seems like you're arguing against your own point here, though?
A low point in Europe, sure.
That was just an example that is trending for the whole europe and asia, for the rest, visit the links. Don't be lazyYeah if you square that vs the Amazon rainforest's deforestation alone I'd wager that the UK's woodland increase in the last 700 years is irrelevant and that's before including the rest of the world.
Factor in Russia alone an area the size of Belgium that is currently burning and there's an awful of more wildfire activity in the Northern Hemisphere now. These fires are going to burn for months.Yeah if you square that vs the Amazon rainforest's deforestation alone I'd wager that the UK's woodland increase in the last 700 years is irrelevant and that's before including the rest of the world.
Always curious as to how do these fires start.Factor in Russia alone an area the size of Belgium that is currently burning and there's an awful of more wildfire activity in the Northern Hemisphere now. These fires are going to burn for months.

Lightning strikes, arson, electrical equipment arcing, the usual stuff plus tinder dry grass. Get the same shizzle in Australia every summer, but it’s more expected here.Always curious as to how do these fires start.
A friend of mine recently told me that the only way that we are going to tackle Climate Change is through leaving the EU.Tweet

Have they asked for help? Just yesterday I watched Bolsonaro saying the NGO's are to blame for the fires, that the fires are normal at this time of the year and he sees no need in using the army to help fight them.I read with horror that the Brazilian government says that it does not have the resources to fight the massive number of fires in the rain forest.
Surely if climate change is such a high priority, why are the other governments not falling over themselves to offer their support and help.
One minute I am optimistic that the penny is dropping and CC is now really high on the public agenda.
And the next minute we hear about the huge increase in Rain Forest deforestation.
The level of human stupidity has no bounds...
He should be 'persuaded' to ask for help with financial inducements.Have they asked for help? Just yesterday I watched Bolsonaro saying the NGO's are to blame for the fires, that the fires are normal at this time of the year and he sees no need in using the army to help fight them.
Remember Brazil (and south america) are the USA backyard. I would assume, any help needs to be authorized by them first, and of course, they prefer to let the rainforest to burn a little bit longer. More space to install their farming and mining industries.I read with horror that the Brazilian government says that it does not have the resources to fight the massive number of fires in the rain forest.

Ahhhhhh yes. Climate change and CO2 emissions pay attention to country borders.A friend of mine recently told me that the only way that we are going to tackle Climate Change is through leaving the EU.
I could hardly believe my ears.
But he is convinced that 'when we get back control of our borders' we can control the population and hence control CO2 emissions.
I did remind him that CC is a global problem but it just goes to show how narrow some peoples views are. Particularly Brexiteers.
Thank you for this.Remember Brazil (and south america) are the USA backyard. I would assume, any help needs to be authorized by them first, and of course, they prefer to let the rainforest to burn a little bit longer. More space to install their farming and mining industries.
Now that the news has finally reached the mainstream, after weeks of hiding it, help will start coming.
Chile government announced today they are in talks with Brazil officials and offering help.
I would be very interested to hear about the work you are involved with.Ahhhhhh yes. Climate change and CO2 emissions pay attention to country borders.
Am doing quite a bit of work in this field, and considering the UN report on climate change, theres no point getting too stressed about mitigating against climate change. It's too late... we are f*(&ed.
Well we are doing work for local government on their Strategic Environmental Assessment. Large team of PHDs and MSCs and it's all quite alarming. Basically 15 or so years left before we pass the tipping point, and at the rate we going we wont manage to course correct in time.I would be very interested to hear about the work you are involved with.
Despite being a huge optimist, I am becoming less and less convinced that the species who is responsible for the damage has the wherewithall to do anything about it.
Thank you and I wish you well in your job.Well we are doing work for local government on their Strategic Environmental Assessment. Large team of PHDs and MSCs and it's all quite alarming.

The fire forest that are happening is probably nothing to be worried on thegic scheme of things. Is very visual and terrifying but has probably not much impact at the rate is happenning. Another thing is that it will get worse and worse, but right now that should not worry us. What it matters is our consumption pattern. Specially the meat/dairy industry and the energy consumption. You tackle both (veganism/0 waste + renewables) and the solution would be there. Unfortunately, is too late for this drastic changes as it will not come for the will of the people to change nor the governments will implement anything against the big coporationsThank you and I wish you well in your job.
It is incredible is it not that our planet is some 4.5bn years old and humans have been around for a tiny fraction of that time AND we claim to be an intelligent species.
AND yet, as your work now tells us that we have about 15 years before we pass the point of no return for damaging climate change.
I am a grandfather of 4 young children. And I look at them with genuine fear as to what their world is going to be like for them.
Me and my wife are doing our best to reduce our CO2 output.
But all of this is swamped by the devastating fires in both the Arctic and Brazil.
To say that I am angry is a massive understatement.

A majority in the UK doubt the existence of man made climate change? Surely not. That's just...depressing.A brexiteer who has actually believes in man made climate change seems to be a rarity in my experience.
Most polls I've come across seems to have UK beliefs at around 45% for man man made climate change, wonder what political assertion those other 55% might be.

"The Climate Change Act 2008 set the country's emission reduction targets. The "legally binding"targets are a reduction of least 80% by 2050 (against the 1990 baseline)."A friend of mine recently told me that the only way that we are going to tackle Climate Change is through leaving the EU.

Thank you. He is one of those who really believes the Brexit publicity and that everything will be sorted out when we leave."The Climate Change Act 2008 set the country's emission reduction targets. The "legally binding"targets are a reduction of least 80% by 2050 (against the 1990 baseline)."
I wonder if your friend is thinking of this. In 1990 the population was estimated at 57 million by 2030 its projected to be 71 million. Its not making reaching the targets any easier, that is for certain but Brexit thinking on it stopping immigration is probably wrong anyway.
I've been so pessimistic about things that 15 years actually a lot of time to me - I remember about 10 years ago people saying we had 7 years to sort things out. It's crazy how we're still burning fossil fuels and forests like there's no tomorrowRead up above there, by spaceboyrsa.
Firstly well done for choosing to study Engineering. It may not be the most popular or most financially rewarding career but Engineering is actually something that the UK is very good at. I am a retired Gas Turbine Aero Engineer and in the main found it highly rewarding.Question - as someone who's always worried about climate change but never really studied it in detail (3 years left of an engineering degree in college), how fecked are we in the near and far future? How much leeway have we?
