Global warming


NASA, NOAA data show 2016 warmest year on record globally


Asian temperatures could rise disastrously


Profligate fossil fuel use could cause Asian temperatures to rise by 6°C, bringing floods and food shortages for hundreds of millions.

LONDON, 21 July, 2017 – Unrestrained climate change could have serious consequences by forcing Asian temperatures drastically upwards; it could limit economic growth and reverse recent human advances for hundreds of millions, according to a new study. 


Climate refugees will search hard for homes

Where can the climate refugees go, if 2 billion are driven away by rising tides, and the interior available becomes ever more inhospitable?

LONDON, 29 June, 2017 – By 2060, around 1.4 bn people could be climate refugees, driven from low-lying coastal cities by sea level rise. By 2100, as the global population may have reached 11bn, there could be 2bn climate refugees.



Climate change causes killer heatwaves

LONDON, 14 June, 2017 – In southern Asia, mortality is likely to rise with the thermometer. Researchers have established a direct link between global warming and heat-related deaths from killer heatwaves.

A tiny rise of 0.5°C in mean summer temperatures in India or another comparable tropical developing nation could result in a 146% rise in mass death from the heat.

The message is that even moderate increases in mean temperature will have negative effects on human health. And for the poorest – and in India more than 300 million people live on an income of less than $1.25 a day – the effects could be fatal.

Paris 1.5°C target may be smashed by 2026

What appears to be a recent change to a positive phase of the Interdecadal Pacific Oscillation is likely to accelerate global warming, breaking through the agreed Paris target of 1.5°C by as early as 2026.


As Arctic Ice Vanishes, New Shipping Routes Open

As global warming melts sea ice across the Arctic, shipping routes once thought impossible — including directly over the North Pole — may open up by midcentury. But high costs may keep the new routes from being used right away.


About 13.1 Million People Could Be Displaced by Rising Sea Levels, Study Suggests

As of January 4, 2017, the sea level is about 88.2 milliliters, as per NASA's Vital Signs of the Planet. The rate of change of sea level is estimated to be 3.4 milliliters per year.


We owe our planet this climate march. But we also owe it – very faint – hope

If the capitulation of some parts of the establishment, and the invigoration of some progressive leaders, count as two small positives, there’s also a third: the unleashing of the full energy of lots and lots of people who have had to speak more softly in the past.


Cold snap: massive iceberg just off coast draws Canadians eager for close-up

The iceberg, which has dwarfed the nearby small town of Ferryland, is estimated to measure some 46 metres (150ft) at its highest point. “It’s the biggest one I ever seen around here,” mayor Adrian Kavanagh told the Canadian Press. “It’s a huge iceberg and it’s in so close that people can get a good photograph of it.”


Rising Walls, Falling Bridges

Even more than politics, all weather is local. So, while most of the nation basked in record warmth this week, the West Coast was battered again by a system carrying enough water vapor to equal the flow of about 10 Mississippi Rivers.

The U.S. is Poised to Set a Record-Setting Record

There have been 3,146 record highs set for the month-to-date compared to only 27 record lows, ensuring February will go down as the 27th month in a row with more highs than lows. The astonishing 116-to-1 ratio of highs to lows would easily set a record for the most lopsided monthly ratio in history. There have also been 248 monthly record highs and no monthly record lows.

Long-term sea level rise set in motion by near-term carbon emissions threatens major coastal cities across the world. Here we present paired images showing how iconic locations — in London, Shanghai, Mumbai, Sydney, Rio de Janeiro, Durban and New York — could fare under scenarios of business as usual vs. a sharp transition to clean energy.


Australia’s new normal … as city temperatures hit 47C people shelter from the deadly heat

Australians are no strangers to hot weather. But for the past week large parts of the continent have suffered a heatwave of unusual length and intensity. Temperature records were beaten in cities and rural towns around the country.


 It's more than just climate change 

The disparity is even greater when inequality within countries is included. For example, about 50 percent of the world's people live on less than $3 per day, 75 percent on less than $8.50, and 90 percent on less than $23. One effect of this inequality is that the top 10 percent produce almost as much total carbon emissions as the bottom 90 percent combined.


Heat waves are not unusual in Australia

This map shows peak land surface temperatures between February 7 and 14, 2017, a period when some of the most extreme heating occurred. The map is based on data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite.


Heat Is On for 2017, Just Not Record-Setting

While that streak is expected to end, in part because of the demise of one of the strongest El Niños on record, 2017 is still expected to be among the hottest years in more than 130 years of record keeping, according to a forecast from the U.K. Met Office.



Arctic ice melt 'already affecting weather patterns where you live right now'

The dramatic melting of Arctic ice is already driving extreme weather that affects hundreds of millions of people across North America, Europe and Asia, leading climate scientists have told the Guardian.


2016 Is Days Away from Sealing Record-Hot Spot

It will be the third straight record-setting year — and of the 17 hottest years, 16 have been this century — a clear sign of the human-caused rise in global temperatures caused by the buildup of heat-trapping greenhouse gases over the past century.


Climate Change Will Stir ‘Unimaginable’ Refugee Crisis

Climate change is set to cause a refugee crisis of “unimaginable scale,” according to senior military figures, who warn that global warming is the greatest security threat of the 21st century and that mass migration will become the “new normal”.


Temperature and Precipitation Maps

The combined average temperature over global land and ocean surfaces for October 2016 tied with 2003 as the third highest for October in the 137-year period of record, at 0.73°C (1.31°F) above the 20th century average of 14.0°C (57.1°F).


Was that climate change? Scientists are getting faster at linking extreme weather to warming 

Is it still true to say you can’t point to any single extreme weather event and claim you can’t link it to human-caused climate change?

Plenty of people seem to think this is still the case. But a rapidly evolving field of climate science suggests that it’s not. 


Cumbrian lakes hold a centuries-long flood record

Any plan to protect homes and businesses from flooding has to understand the scale of the problem being confronted.


These Images Show Near-Record Low 2016 Arctic Sea Ice

This year has been exceptional by many standards. March saw the lowest sea ice maximum ever recorded followed by a string of record low months. The Northwest Passage opened up, allowing a luxury cruise ship to travel from Anchorage to New York. And a freak storm in August turned ice thin and brittle near the North Pole.


August Ties July as Hottest Month Ever on Record

In NASA’s dataset, August marks the 11th record-setting month in a row. That streak goes back 15 months through July in data from the National Oceanic and Atmospheric Administration. Each agency handles the global temperature data slightly differently and uses a different period of comparison, leading to slight differences in the monthly and yearly temperature numbers. Overall, though, both datasets show clear agreement in the overall warming trend.

Temperatures in India reach a terrifying 123 degrees.

India is no stranger to high temperatures and large disasters: 2015 was an especially devastating year for the country, with heat, drought, and floods killing hundreds of citizens. All of these disasters have been linked to climate change, which especially affects developing nations like India, where over 20 percent of the population lives on less than $1.90 a day and 300 million lack electricity.


World heading for catastrophe over natural disasters, risk expert warns

Last year, earthquakes, floods, heatwaves and landslides left 22,773 people dead, affected 98.6 million others and caused $66.5bn (£47bn) of economic damage (pdf). Yet the international community spends less than half of one per cent of the global aid budget on mitigating the risks posed by such hazards.

How This El Niño Is And Isn’t Like 1997

So it’s no wonder that it is the touchstone event that people think of when they hear that name. And naturally, as the current El Niño event has gained steam, the comparisons to 1997 have been increasingly bandied about.


Strong El Niño Brings Warmer Global Temperatures

The strong El Niño is likely playing a role as the average global temperature of an El Niño year is 0.4°F higher than a La Niña year. However, the strong El Niño is not solely responsible for the warming planet. Global temperatures have been trending upward since 1950, regardless of whether or not the Pacific Ocean was in an El Niño, La Niña, or neutral phase. In fact, La Niña years in the 21st Century are now warmer than El Niño years just 30 years ago.
