Global temperatures in 2018 were the fourth warmest on record, US government scientists have confirmed, adding to a stretch of five years that are now collectively the hottest period since modern measurements began.

Global Warming Made 2018 Temps Historically Hot

The world in 2018 was 1.5F (0.83C) warmer than the average set between 1951 and 1980, said Nasa and the National Oceanic and Atmospheric Administration (Noaa). This means 2018’s average global temperatures were the fourth warmest since 1880, placing it behind 2016, 2017 and 2015. This follows a broader pattern of human-induced climate change, which is boosting increasingly punishing heatwaves, sea level rises and extreme weather. Last year saw a pair of devastating hurricanes hit the eastern US, while record wildfires ravaged California. Antarctica's contribution to sea level rise was mitigated by snowfall. By Maria-José Viñas, NASA’s Earth Science News Team A new NASA-led study has determined that an increase in snowfall accumulation over Antarctica during the 20th century mitigated sea level rise by 0.4 inches.

Antarctica's contribution to sea level rise was mitigated by snowfall

However, Antarctica’s additional ice mass gained from snowfall makes up for just about a third of its current ice loss. “Our findings don’t mean that Antarctica is growing; it’s still losing mass, even with the extra snowfall,” said Brooke Medley, a glaciologist with NASA Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study, which was published in Nature Climate Change on Dec. 10. Union of Concerned Scientists. Factcheck: What Greenland ice cores say about past and present climate change. Causes. › en español Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 — warming that results when the atmosphere traps heat radiating from Earth toward space.


Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks. " Gases that contribute to the greenhouse effect include: Water vapor. On Earth, human activities are changing the natural greenhouse. The consequences of changing the natural atmospheric greenhouse are difficult to predict, but some effects seem likely: On average, Earth will become warmer. ISWA: In Defense of Science – Global Warming is Not an Opinion « Opinion. As the now famous young Ms Greta Thunberg from Sweden said in Katowice, Poland, -“You’re never too small to make a difference!”

ISWA: In Defense of Science – Global Warming is Not an Opinion « Opinion

Science is establishing facts through investigations and research. It aims to advance our understanding of causes and effects and the nature of reality. So, let’s start with what we know. Scientists Agree: Global Warming is Happening and Humans are the Primary Cause. Human fingerprintsImage: IPCC AR5 The evidence is overwhelming.

Scientists Agree: Global Warming is Happening and Humans are the Primary Cause

- The Washington Post. How the Weather Gets Weaponized in Climate Change Messaging. It’s time to be scientific about global warming, says climatologist Judith Curry. We’ve all come across the images of polar bears drifting on ice floes: emblematic victims of the global warming that’s melting the polar ice caps, symbols of the threat to the earth posed by our ceaseless energy production—above all, the carbon dioxide that factories and automobiles emit.

It’s time to be scientific about global warming, says climatologist Judith Curry.

We hear louder and louder demands to impose limits, to change our wasteful ways, so as to save not only the bears but also the planet and ourselves. In political discourse and in the media, major storms and floods typically get presented as signs of impending doom, accompanied by invocations to the environment and calls to respect Mother Nature. Only catastrophes seem to grab our attention, though, and it’s rarely mentioned that warming would also bring some benefits, such as expanded production of grains in previously frozen regions of Canada and Russia. Nor do we hear that people die more often of cold weather than of hot weather. Curry is a scholar, not a pundit. Global Warming and Its Effects. Global Warming Issue Unites World Opinion. Guest Opinion: Global Warming Twenty Years Later.

Tipping Points Near Today, I will testify to Congress about global warming, 20 years after my June 23, 1988 testimony, which alerted the public that global warming was under way.

Guest Opinion: Global Warming Twenty Years Later

There are striking similarities between then and now, but one big difference. Again a wide gap has developed between what is understood about global warming by the relevant scientific community and what is known by policymakers and the public. Now, as then, frank assessment of scientific data yields conclusions that are shocking to the body politic.

Now, as then, I can assert that these conclusions have a certainty exceeding 99 percent. World Opinion on the Environment. More on: Global Energy and Climate Policy Polls and Public Opinion This page is part of Public Opinion on Global Issues.

Perception of Climate Change as a Problem or Threat A majority in every country polled says that global warming is a problem or a threat and that governments should give it a high priority, while only small minorities say it is not a problem. Readiness to Take Action Large majorities around the world support taking action to address the problem of climate change. Changing Energy Usage To motivate changes in energy usage, majorities in most countries believe that it will be necessary to increase the cost of energy that causes climate change.

Reducing Reliance on Oil and Coal Role of Developing Countries Multilateral Efforts to Address Climate Change Assessing Country’s Government in Addressing Problem. Public Opinion on Global Warming, Environment and Energy. Section 7: Global Warming, Environment and Energy Opinions about the environment and energy sharply divide the typology groups, with the two predominantly Republican groups – Steadfast Conservatives and Business Conservatives – standing out for their skepticism of global warming and relatively low support for environmental protection.

Public Opinion on Global Warming, Environment and Energy

The other typology groups generally express pro-environmental views, and majorities in these groups say the average temperature on Earth has increased over the past few decades. However, most typology groups also favor building the Keystone XL pipeline, with the notable exception of Solid Liberals. Quora.
