I want to shout about climate change but I’m too polite. Writing is easier for somebody quiet like me.
In my first venture into blogging, I begin my quiet contribution to the climate emergency response by recapping the climate change story so far.
Climate Change is Happening
“Right now we are facing a manmade disaster of global scale, our greatest threat in thousands of years: climate change,” said Sir David Attenborough at the United Nations summit on Climate Change.
Attenborough was speaking to politicians gathered from around the world shortly after scientists had warned governments they only have until 2030 to stop the most damaging effects of climate change.
The Intergovernmental Panel on Climate Change (IPCC), which uses research from the world’s leading scientists, published a report on 8th October 2018 flagging the dangers of allowing increases in global temperatures to continue rising.
Global temperatures in 2018 were the fourth hottest since modern measurements began in 1850. The three hottest? 2016, 2015 and 2017.
Derek Schmidt, a top NASA scientist, said that 2018 was “quite clearly the fourth warmest year on record and it was probably warmer than many hundreds of years before that”.
We see the effects of higher temperatures through news reporting on the devastation caused by storms, floods, droughts and wildfires. We know climate change caused by increases in global temperatures makes events, like the recent floods in Mozambique and the wildfires that scorched California, more likely and more severe. Schmidt confirmed, “The impacts of long-term global warming are already being felt – in coastal flooding, heatwaves, intense precipitation and ecosystem change.”
The World Meteorological Organisation (WMO), which uses thousands of weather stations, ships, aircraft, radar and satellites to take measurements from land, sea and air, also measured 2018 as the fourth warmest on record.
“The degree of warming during the past four years has been exceptional, both on land and in the ocean.” said the boss of the WMO, Petteri Talaas. “Many of the extreme weather events are consistent with what we expect from a changing climate. This is a reality we need to face up to.”
Climate Change is Man-made
“Comprehensive assessment by scientists shows that it is extremely likely that human activity has been the dominant cause of warming since the mid-20th Century.” So say the Committee on Climate Change (CCC) which advises both UK and Scottish governments.
They point out there is strong evidence that increased amounts of greenhouse gases released into the atmosphere by human activity is the cause of global heating.
Scientists have known since the early 1800s that greenhouse gases, which include carbon dioxide, trap heat from the sun. The amount of greenhouse gases in the atmosphere fluctuates naturally by a small amount but there has been a massive spike in the amounts recorded since 1950. Levels are now well above the natural cycle of the last 800,000 years.
The 1950s was the dawn of the modern lifestyle we now enjoy. Governments spent billions to help economies recover after the Second World War and the post war ‘golden age’ was fuelled by a boom in oil production. ‘Black gold’ became the world’s most important natural resource. The number of barrels produced increased from 10 million per day in 1950 to 50 million per day by 1970. We now produce more than 80 million barrels per day.
The lives we live are dependent on oil. We use it to fuel our vehicles, heat and light our homes and make the chemicals and plastics that underpin our modern lifestyle. However, burning oil, and other fossil fuels, belches greenhouse gas emissions into the atmosphere, trapping heat from the sun.
Scientists say there is a 95% probability climate change is man-made.
Our Future is at Risk
A global movement has grown from the concerns of young people for their future. Young people across the world are choosing not to attend school to protest against politicians response to climate change.
Greta Thunberg, the Swedish school girl who inspired the school strikes, has become the voice of future generations. In a no-nonsense speech to MPs at the Houses of Parliament she said, “You lied to us. You gave us false hope. You told us that the future was something to look forward to. ”
The climate change predictions made by scientists in the IPCC report make the risks to future generations frighteningly clear. We are warned that sea level rises will wipe out small islands, like the Maldives, and large coastal cities, like Miami, and life in many parts of the oceans will die. On land, habitats will be transformed and many species will become extinct. For humans, poverty and disadvantage are expected to increase, health will be affected by heat related illness and the spread of disease, such as malaria and dengue fever, growing crops to feed ourselves will become harder and water will become more scarce.
“And the saddest thing is that most children are not even aware of the fate that awaits us,” Thunberg quietly raged.
Safeguarding our planet
Scientists have worked out we can reduce the impacts of climate change if we limit global heating to 1.5C above pre-industrial levels. Average global temperatures are currently at 1C above and rising fast. The IPCC predict we only have ten years left to make the “far-reaching and unprecedented changes” needed to avoid the biggest dangers of climate change.
“The good news is that some of the kinds of actions that would be needed to limit global warming to 1.5C are already underway around the world, but they would need to accelerate,” said Valerie Masson-Delmotte, one of the authors of the IPCC report.
To help accelerate Scotland’s response, the CCC recently urged the Scottish Government to set a target to reach net zero emissions by 2045. This means any greenhouse gases released into the atmosphere must be taken back out so that the overall level remains the same.
Responding to the CCC’s advice, Roseanna Cunningham, the Cabinet Secretary responsible for Scotland’s response to the Climate Emergency promised,“this government will be placing climate change at the heart of everything we do,” and issued a rallying call, “Our response to the climate emergency will impact on how we live as a society and on how our economy operates. This must be a shared, national endeavour: we all need to think more about how we can make our lives more sustainable, cutting down on waste and excess.”
I will help with this endeavour by trying to make my voice heard at home, at Parliament and, now, on social media.
I have started by sharing what I know about climate change. I will be keeping myself up to date with what is being said, what is being done and what more I could be doing to safeguard the planet for future generations.
I will make my quiet contribution to the climate emergency response and write about it here.
