Banning petrol cars by 2030
As part of the UK's move to become more carbon neutral, the government announced that it plans to ban the sale of petrol cars by 2030 meaning that electric cars will dominate the market; this is great news for the environment but there are concerns around ensuring that there is enough infrastructure to cope with the numbers of cars and vehicles that will need regular recharging

Oil pollution in the Arctic
New rules around shipping in the Arctic have been recently brought in to protect it from oil pollution which can threaten wildlife; it appears, however, that some of these rules don't go far enough as there are several loopholes that allow ships from Arctic coastal states to sail around which will mean that some oil will still enter the waters

Hurricane Zeta makes landfall in the US

The US has seen another powerful hurricane make landfall this week after building up speed and strength in the Gulf of Mexico.  Hurricane Zeta moved inland through Louisiana and Mississippi on Thursday and left more than 2.6 million people without power across a number of southern states.  Wind speeds are thought to have reached 100mph and six people are known to have died.  

A lot of damage has been done to buildings and power lines as the fierce winds ripped through the streets and brought down trees and electrical cables.  In coastal areas, flood waters have risen and flooded people's homes and businesses.  For residents of New Orleans who remember the damage caused by Hurricane Katrina, this has brought back some difficult memories from that time.

The US has seen 27 storms so far in this year's hurricane season.  It normally sees around 6 hurricanes and 12 large named storms.  This increase in storm frequency is becoming part of an all too common change in global weather patterns.  Climate change is adding warmth and moisture to these storms which makes them more powerful, more frequent, and more likely to cause devastating damage when they reach land.  If the US and other countries around the world can work together to reduce carbon emissions, it should help stop the frequency of these storms which will help save lives and save money from the cost of damage caused.

Losing the Great Barrier Reef

Scientists have been monitoring the Great Barrier Reef for several decades. The phenomenon of coral bleaching is now widely known as a devastating impact of the warming oceans that they live in.  This is a stress response by the coral that causes them to expel the algae that live inside them, resulting in the coral losing the bright colours that the algae give them and returning them to their white skeletal colour. 

The warming seas are a direct result of climate change.  When the earth's atmosphere warms, the water warms with it. Marine life such as coral are extremely sensitive to these changes and cannot tolerate even a small rise in temperature.   The coral starts to die and this has a knock on effect on the species and organisms that feed on and live off the coral.  

Australia's Great Barrier Reef is now thought to have lost around half of all its coral since 1995. This has occurred across all types and sizes of coral, and we are now seeing reduction in the sealife that use the coral as a habitat too. 

The warming has also contributed to the growth of other organisms that thrive in warmer waters and this is changing the balance of the ecosystems.  So what can be done?  The main answer would be to halt the rise in global temperatures.  This is a difficult challenge and can only be done by committing to reducing greenhouse gas emissions and investing in renewable energies.  We can also try to limit our plastic pollution as this can also harm the wildlife that live in this delicate ecosystem.  Scientists are also looking at ways to restore coral reefs and grow it back by creating coral nurseries.  This looks to be a successful option but will take time to establish and will only be sustainable if temperatures don't continue to rise.

The future of wind power

There has been a lot in the news this week about the future of wind power.  Britain is looking to invest more money than ever in new offshore wind farms in order to make this the main source of energy for homes and businesses.  This is a good move as it will make our energy cleaner and more sustainable, and it will reduce our reliance on importing energy and being subject to sudden changes in oil and gas prices.  

The government is proposing to spend £160 million on building turbines and updating existing facilities, and in the process will create 2,000 new jobs. This will generate more security in the green economy and should hopefully make a good base to support more green jobs in the future. 

The main benefit of investing in wind power is that it will reduce the amount of carbon dioxide and other greenhouse gases that are pumped into our atmosphere every day.  This will help the UK reach its climate change goals for 2050 and will contribute to the global effort to minimise the impacts of climate change.  If carbon emissions were to continue at the current rate, we would start to see even more extreme weather events such as floods and wildfires, and our oceans would be at risk from increased warming.  This endangers all wildlife on land and in the sea and so it is vital that we don't let our ecosystems deteriorate any further. 

The investment in clean energy is part of what is being called the 'green recovery' from the recession caused by the coronavirus pandemic.  Making sure we 'build back greener' is essential to ensuring we meet climate targets, become independent in our energy generation, and ultimately protect our planet so that we don't interfere and damage any further the wilderness areas.

World's wildlife facing a crisis

If you watched David Attenborough's latest programme called 'Extinction: The Facts' on Sunday night, you will be fully aware of the problems facing the world's wildlife.  Most of these have been caused by our human actions and decisions we have made, often when we are far away from the consequences.  It is only when we see programmes like these that we become fully aware of the bigger picture and the harm that is happening to wildlife and also to people who live in the most poverty-stricken areas of the world. 

Deforestation is a huge issue, and is the most common cause of most loss of wildlife.  This is driven by the need to farm cattle, sheep and goats, or to grow animal feed crops such as soya which requires huge amounts of land, fertiliser and water.  It is usually cheaper to just clear new land than to help recover and reuse previously farmed land.  

Fishing is another problem.  Fish are caught inside huge industrial nets which catch many other fish and sea life, not just the desired species that they are after.  Quotas may be in place but are not monitored or enforced properly.  Many animals each year are entangled in fishing-related equipment or consume plastic items which remain inside their stomachs and cause death if they are unable to feed successfully. 

Animal poaching is a hidden problem that continues to happen without much detection.  Many animals such as rhinos, elephants and pangolins are trapped and killed for their horns, tusks or scales in the belief that they will cure diseases such as cancer, and they can sell for thousands of dollars on the black market.  Animals may also be kept alive in terrible conditions and have very poor quality of life. 

The UN announced in a report yesterday that the world has failed to meet any of its targets set out in Japan in 2010 to protect wildlife and reverse the damage that has already been done.  They have said 'humanity is at a crossroads' and that it is up to us to take the next steps.  Some progress has been taken in some areas, but large areas of vegetation and habitat are still being destroyed and many species are still at risk of extinction particularly in areas such as South America.  

Governments can make decisions that will help put laws in place, but it is also up to us as individuals to take actions that will reduce our impact on the planet.  To find out more visit the links below:

Hurricane Laura hits the US

A new storm named Hurricane Laura has made landfall in the south US this week. The storm was labelled a category 4 (the highest being category 5) with wind speeds of around 150 miles per hour.  It was headed towards the states of Texas and Louisiana which is just west of the city of New Orleans which was battered by Hurricane Katrina back in August 2005.  

As Hurricane Laura approached, half a million people were told to leave the area in case of storm surges but the effects of the storm were not as bad as were feared.  There were widespread power cuts to around half a million homes and the strong wind speeds caused damage to buildings and vehicles.  Six people are known to have died, four from falling trees, one from a boat that sank and one from carbon monoxide poisoning.  There was also a chemical fire at an industrial plant.  Overall, the storm was less damaging than was expected as it quickly lost its power over land and began to track east.  It has now been downgraded to a tropical storm and 1,500 people have moved in to help with the clean up operation.

This is probably one of the first of many storms during America's hurricane season. The UK also saw bad weather this week with Storm Francis bringing heavy rain and unseasonably strong winds of up to 80mph.   With climate change continuing to alter weather patterns, it is only looking increasingly likely that we will have more of these storms in the future and will have to look at better ways of mitigating their impacts.

Drilling for Arctic oil

Many parts of the Arctic have been drilled for oil over recent decades. The rock beneath the ice and snow holds a wealth of natural fossil fuels which various governments and corporations have sought to exploit in order to benefit from the profits and industrial development that such a resource brings.

This week, it has come to light that the US government is now going to allow a new plan to go ahead to drill in the Arctic National Wildlife Refuge.  This is an area in north-east Alaska which is home to many different animals including reindeer and polar bears and many other mammals and birds. It sits above millions of barrels of oil which can be extracted by drilling deep down into the ground.

The government say that drilling for oil will provide jobs for hundreds of Alaskan people and generate large amounts of income for the area.  However, we have already seen from other projects like this that the environment is usually destroyed to the point of no return and animals have to migrate elsewhere which disrupts the balance of the ecosystem.  

Many people also feel (now more strongly than ever) that there is no room for these kinds of projects with the current impacts of climate change hitting almost every corner of the globe.  They believe money should be being invested into green alternative energies, and not finite fossil fuels whose reserves will quickly be used up. There is no need that is great enough to risk having the oil spills, habitat destruction, noise pollution, and the increased greenhouse gas emissions that would result from another oil refinery.  

Arctic areas are seeing the impacts of global warming more than ever, with ice melting at an increasing rate and more and more risk to polar bears who rely on the ice for fishing and migrating.  It seems, illogical, therefore, to go ahead with such an outdated and dirty fossil fuel extraction project in an area that it trying to cling on to its status as a pristine wilderness.

'Highest recorded temperature' in the US

The US's west coast has recently been experiencing a heatwave which is sending temperatures soaring. Some days were so hot that it caused a power plant to malfunction and there were blackouts in certain areas.   A recent reading has shown the thermometer in Death Valley to reach 54.4 degrees C which is thought to be the highest and most credible temperature reading in history (there have been some slightly higher recordings in the past but these are though to be inaccurate).

This recent heatwave is yet another indicator of a rapidly warming climate.  The hot weather is stretching across four or five states from Arizona up to Washington, with extreme weather phenomena such as firenadoes being seen in California.  People are having to cope with a loss of electricity and an increase in pressure on the health systems as people struggle to manage in the extreme heat.

Severe heat waves and droughts can also have impacts on the land and wildlife.  Crops will begin to fail if they go long enough without adequate water.  If forest fires break out, animal habitats and their food stores will be destroyed and it will be difficult for them to find new areas.  Flash floods that often follow heatwaves can also damage land and wash away valuable soils, making it harder for vegetation or crops to regrow.

Fires in the Amazon

The Amazon Rainforest in Brazil is already seeing an alarming increase in the number of fires it usually experiences, and it is only the start of the new fire season. Around 10,000 fires have been spotted within the first 10 days of August which is a rise of 17% on last year.  To many people who know the value of the Amazon and want to protect it, this is not good news.

Rainforests such as the Amazon are huge stores of carbon, and as such are vitally important in the fight against climate change.  Organisations in Brazil are aware of this and are trying to protect the trees from fires that not only destroy the trees and habitat for wildlife, but also release tonnes of carbon dioxide into the atmosphere at the same time.  

Unfortunately, it seems that although Brazil's government have made agreements to protect the Amazon, not enough has been done on the ground to prevent these fires from being started.  Many people, both local villages and large scale companies, are keen to burn vegetation to make way for farmland as this is much more profitable.  However, it will take far too long for the trees to grow back into the complex network they were once in, and for the wildlife and ecosystem processes to return.  Many believe that with a changing climate, the rainforest may end up lost forever with only dry or temperate grasslands in its place.

Climate change affecting UK's weather

The UK is seeing an increasing number of warm spells with temperatures now regularly reaching above 30 degrees.  Last week, the UK recorded its third warmest day ever and another wave of high air pressure is set to bring soaring temperatures again next weekend.  This is all part of a pattern of increasing extreme weather that the UK is seeing, with more flooding events and warmer winters than ever before.

Scientists believe that these weather patterns are a direct result of climate change, and if actions are not taken then we will continue to see increasingly unpredictable weather events.  This not only causes problems for people living in flood risk areas, but it also puts farming livelihoods at risk which could make food production a problem.  Ecology and local ecosystems could become unbalanced with wildlife struggling to adapt to the changes.  

We are seeing efforts made towards becoming more carbon neutral.  The UK is now hardly dependent on coal as a fuel source, with most coal power stations now shut down.  However, more needs to be done both at government level and individual level to reduce the amount of carbon emissions we produce. 

Read this government report to find out what the UK is doing to build a green and healthy future.
