Owl’s Residence is concerned about how our atmosphere will have an effect on owls in southern Africa. After performing some analysis we located that the owl – like several other bird species – faces a variety of challenges to sustain its existing numbers. These birds of prey play vitally essential roles in the preservation of our ecosystems and biodiversity. The high and intermediate conservation priority owl species at the moment incorporate the African Grass Owl Tyto capensis, the Marsh Owl Asio capensis and the Cape Eagle-Owl Bubo capensis.

Some of the threats to owl populations include:

1. Habitat loss

According to Cape Nature the loss and degradation of habitat continues to be the largest threat to avian biodiversity in the country. One of the driving forces behind this threat is the escalating human population growth and its connected impacts on the transformation of essential habitat. Important bird habitat such as indigenous forests has been degraded by means of logging, resulting in a loss or decline of species. These locations have been placed under the management of the South African National Parks, supplying the forests and their inhabitants with better statutory protection. As a establishing country, South Africa requires sustainable development to enhance its economic growth. The regulated Environmental Impact Assessment (EIA) approach aims to either prevent development inside sensitive areas or mitigate those aspects of development that would seriously impact on the environment.

2. Powerlines

Powerlines pose a critical threat to birds either by means of birds colliding with the conductors or via electrocution, whilst landing, perching or taking off from these structures. Eskom is totally aware of the impact that their structures have on South Africa’s birdlife and have formed a partnership with the Endangered Wildlife Trust (EWT) to monitor the problem and to create and increase mitigation measures to decrease bird mortalities. A number of Eskom powerlines in the Western Cape are ending their lifespan and are becoming refurbished and re-routed about sensitive areas. The erection of powerlines above 33kV is a listed activity in terms of the environmental impact assessment regulations.

3. Roadside bird mortality

Barn Owl a Victim of Roadside Mortality by Google Images

With the improve in the quantity of quick-moving vehicles and the simultaneous development of road developing technology, roadside bird mortality has turn into an increasingly essential environmental problem. 554 owls of four species, namely Marsh Owls, the Red Data listed Grass Owl, Barn Owl and the Spotted Eagle Owl were collected on the stretches of the R550 and N17 roads in the rural regions in between Springs and Devon in the East Rand of Gauteng Province during the period among October 2001 and September 2003. It was located that greater site visitors speeds undoubtedly having an increasingly detrimental impact on the owl mortalities. Weather circumstances also play a role in mortality counts, with the mortalities getting drastically negatively correlated to rainfall. Gravel roads had really low incidences of owl mortalities with the highest mortalities recorded along tarmac roads that are bordered by open grasslands or cattle grazing paddocks. Another element influencing the road mortalities of the owls is grain that is spilled on the road in the course of transport. This initially seemed to be the major element in attracting granivorous rodents to the roads, and in turn, attracting the owls to prey on them.

four. Climate modify

The African climate has often been altering, but the dilemma with current climate alter is thresholds, speed and compound effects. Energy pollution is making the air hotter and richer in CO than at any other time in human history – making ‘non-analogue conditions’. Statistical evidence suggests that South Africa has been getting hotter over the past four decades, with average yearly temperatures escalating by .13

Question by Beans: climate change?
I write an essay on climate change, choosing a side of the debate and arguing in its defense, for school. I want to investigation both arguments first but I am unable to discover an article giving Specific EVIDENCE that ties human activity to climate change apart from “Scientists now agree that…”

do you know of any such articles? can you post a link?

thanks a bunch

The Climate Crisis: An Introductory Guide to Climate Change

An incredible wealth of scientific data on global warming has been collected in the last few decades. The history of the Earth's climate has been probed by drilling into polar ice sheets and sediment layers of the oceans' vast depths, and great advances have been made in computer modeling of our climate. This book provides a concise and accessible overview of what we know about ongoing climate change and its impacts, and what we can do to confront the climate crisis. Using clear and simple graph

The climate is drastically changing all through the world, there are countries that are forever getting colder and colder and there are also nations which are just acquiring hotter and hotter. This has been confirmed by the weather in the UK. We are now seeing terrible bouts of cold climate coming and staying. I was really reading an article only the other day that mentioned in the subsequent decade we could nicely be facing an Armageddon all through the world triggered by the weather. So what could we expect to see in this Armageddon? Let us take a look.

Tornados
Here in the UK we do not truly get that several tornados, but that could all effectively be changing as the winters and the atmospheric conditions get worse and worse. We could effectively see enormous tornados hit the shores of the UK.

Hailstones, Sleet and Snow
With tornados will come sleet and snow, but most worryingly hailstones are going to come and hit us all. But not just tiny hail stones, these hail stones are going to be massive enough to smash vehicles and houses, so the safest bet would be to stay at property.

Immense Hot Weathers
But it is not just the cold that will affect the world we already know that nations such as Australia, Asia and many much more continents are going to literally become way to hot and factors such as fires are going to break out around the world. Not only this, but we are also going to see more and a lot more individuals get skin diseases and the older generation fall victim to issues such as skin strokes.

All this becoming mentioned although are we personally in the UK prepared for such terrible weather. I say this since of one example. If you for instance take a look at the new homes, buildings and structures which are becoming put up all more than the location they are all built with plaster board which is absolutely ridiculous. If the UK ever has an earth quake or bad weather then these house would all become casualties to the weather.

Rest assured that atmospheric conditions are altering a vast quantity and we will start to see in the subsequent handful of months the weather modify. Already in November 2009 before winter has totally kicked in, we have observed the weather change and have observed autumn gusts of about 80 MPH batter the complete nation.

Rough Winds: Extreme Weather and Climate Change (Kindle Single)

For the last few years, and especially in 2011, a new extreme weather event seems to pop up each week. Some decide to stick around: Texas and Oklahoma have been suffering from historic droughts for six months, with no sign of relief. No sooner does Hurricane Irene disappear than Tropical Storm Lee appears to flood Louisiana and stir up wildfires in nearby Texas. We seem beset by more, and more extreme, heatwaves, droughts, wildfires, torrential rainstorms, tornadoes, hurricanes, and blizzards th

Weather is not like climate that typically stays the exact same for much longer periods, weather changes extremely usually every single day or every single hour. 1 day witnesses sunny skies and the subsequent day it is cloudy. Often, it would be a rainy morning and a sunny and warm in the afternoon. The weather changes so typically that it is challenging to predict. One wonders why and how the weather changes.

One the very same hand, Mars is said to be Earth’s twin plant. Mars and Earth orbit about the sun almost at the identical speed. Despite the fact that lately astronomers have discovered newer, smaller planets that resemble with Earth more than Mars does. But Mars function in Earthling history no matter whether actual or imaginary, remains unquestionable. There have been many movies, stories, books and artworks depicting Mars as a globe- in-waiting.

For a extended time, it has been thought that Mars harbor life simply because of the visible changes of color on its surface that is said to be caused by the altering of the seasons. Mars might have harbored life millions of years ago but it remains a mystery why it went extinct. There is a wide belief that Mars has both warm and cold seasons and a surface that looks deceptively fit for human habitation. Human’s mind certainly desires to know why Mars have seasons.

When talking about the changing of weather on earth, there are factors that affect weather changes which are wind direction, elevation and clouds. The direction the air is moving from affects the kind of weather such as air from the ocean will bring in a lot more humid air, air from the desert will bring in dry air and air from the Polar Regions will bring in colder air. The elevation element comes in when the weather will be far more unsettled at the time air is flowing from a lower elevation towards a greater elevation. Weather becomes far more fair and calm when air is flowing from a high elevation towards a lower elevation. The factor of clouds come in when weather tends to be cooler for the duration of the day when there are clouds blocking most of the sun’s heat and UV rays. It will get warmer at night when there are clouds in the sky. The heat that has gathered during the day can not simply dispel at night due to the fact the clouds kept it inside the lower atmosphere near the ground.

Weather modifications also depend on the sort of pressure. Low pressure tends to bring in cloudy circumstances and rainfall. On the other hand, high pressure tends to bring in fair weather. Tropical low pressures do not have fronts. This keeps the air mild even when the weather gets unsettled.

Mars tilts at an angle comparable to earth spins around an axis that does not move up or down. When Mars tilts on 1 side, the northern side points to the sun while on the other side of the orbit which is the southern portion faces the sun also. When most parts face the sun then the sun naturally gets a wider mileage. Back on the surface the sun’s light gets really intense makes the surface a lot warmer. This results in the summer season. The other component that sides away from the sun does not get warm so it is winter season over there. Since Mars has volatile atmosphere, the altering of the seasons is usually accompanied by high temperature swings.
