Climate Change is Real

Thanks to extensive research and noticeable changes in weather and storm prevalence, it’s getting harder to turn a blind eye to the reality of climate change. Since the Industrial Age spurred the increasing usage of fossil fuels for energy production, the weather has been warming slowly. In fact, since 1880, the temperature of the […]

Humans most likely to have caused extreme weather

Extreme weather events over the past decade have increased and were “very likely” caused by manmade global warming, a study in the journal Nature Climate Change said on Sunday.

The high amount of extremes is not normal

Scientists at Germany’s Potsdam Institute for Climate Research used physics, statistical analysis and computer simulations to link extreme rainfall and heat waves to global warming. The link between warming and storms was less clear.

“It is very likely that several of the unprecedented extremes of the past decade would not have occurred without anthropogenic global warming,” said the study.

The past decade was probably the warmest globally for at least a millennium. Last year was the eleventh hottest on record, the World Meteorological Organization said on Friday.

Extreme weather events were devastating in their impacts and affected nearly all regions of the globe.

They included severe floods and record hot summers in Europe; a record number of tropical storms and hurricanes in the Atlantic in 2005; the hottest Russian summer since 1500 in 2010 and the worst flooding in Pakistan’s history.

Last year alone, the United States suffered 14 weather events which caused losses of over $1 billion each. Continue reading Humans most likely to have caused extreme weather

Climate change intensifies El Niño and La Niña

The severe drought in the Horn of Africa, which has caused the death of at least 30 000 children and is affecting some 12 million people, especially in Somalia, is a direct consequence of weather phenomena associated with climate change and global warming, environmental scientists say.

“The present drought in the Horn of Africa has been provoked by El Niño and La Niña phenomena in the Pacific Ocean, which unsettle the normal circulation of warm and cold water and air, and dislocate the humidity conditions across the southern hemisphere,” Friedrich-Wilhelm Gerstengarbe, senior scientist at the German Potsdam Institute for Climate Impact Research (PIK, after its German name), told IPS.

Both phenomena are a part of the southern oscillation climate pattern that occurs across the tropical Pacific Ocean every five to seven years. It is characterised by variations in the temperature of the surface of the tropical eastern Pacific – warming or cooling known as El Niño and La Niña respectively – and a changing air surface pressure in the western Pacific.

Dead turtles wash up on Australian beaches

WWF has received numerous reports from aboriginal groups on the north-eastern coast of Australia of large numbers of sick, starving and dead turtles washing up on beaches. The reports come following the loss of sea grasses after Cyclone Yasi and floods hit the area back in February.

Five species of marine turtle are classified as endangered or critically endangered

The increase in turtle deaths for April may be more than five times higher this year compared to the same time last year.

“If these numbers are accurate, then this is a shocking development for the Great Barrier Reef​” said WWF’s Conservation on Country Manager Cliff Cobbo. “We urgently need clarification from the Queensland Government on how many turtles are being found dead along the Great Barrier Reef coast”.

Turtle hospitals in Townsville, Queensland are being overwhelmed with sick and starving animals and do not have the resources to handle the number of turtles expected to need emergency care over the next 18 months.

Some local aboriginal groups have been so concerned by what they are seeing they plan to suspend issuing hunting permits within their saltwater country.

CEO of the Girringun Aboriginal Corporation, Phil Rist, said large numbers of dead turtles and dugongs had been found in recent weeks and that strandings are occurring on a weekly basis. Continue reading Dead turtles wash up on Australian beaches

Scientists to highlight water insecurity

Demand for water in agriculture and energy production could spike in the coming decades while catastrophic floods and droughts strike more often, a water conference in Canada is to hear this week.

“At unpredictable times, too much water will arrive in some places and too little in others,” said Zafar Adeel, chair of UN Water which coordinates water-related efforts of 28 United Nations organizations and agencies.

Within a generation, water demand in many countries is forecast to exceed supply by an estimated 40 percent.

In other parts of the world prone to flooding, catastrophic floods normally expected once a century could occur every 20 years instead.

Meanwhile, spending on technologies and services to discover, manage, filter, disinfect and desalinate water, improve infrastructure and distribution, mitigate flood damage and reduce water consumption by households, industry and agriculture is expected to rise to a trillion dollars annually by 2020.

Some 300 scientists, policy-makers and economists will release these and other research findings as well as proven new tools, ideas and best practices for optimizing water management at a Canadian Water Network international conference in Ottawa.

The event kicks off on February 28 and runs through March 3. Continue reading Scientists to highlight water insecurity
