Floods are causing widespread economic and non-economic Loss and Damage all around the globe with impacts ranging from loss of lives and damage of infrastructure to health and food security related concerns Floods are hydro-metorological hazards that occur caused due to a variety of both hydrological and anthropogenic factors Challenges such as lack of data and complex nature of interplay between hydrological and anthropogenic factors make it difficult for scientists to attribute floods to climate change

What Is Desertification?

|

|

Desertification is land degradation in arid and semi-arid regions, a change caused by human activities and climatic variations. Desertification reduces water availability, agricultural productivity, biodiversity, and introduces social issues such as poverty and migration. Combating desertification requires sustainable land management practices, reforestation efforts, and international cooperation to restore degraded lands and support affected communities, such as the semi-arid Sahel region in Africa.

Wildfires: Their Impact On Climate, Biodiversity And Society

|

|

Wildfires are increasing in frequency and intensity due to rising global temperatures, posing a significant threat to climate, biodiversity, and society. Wildfires not only contribute to climate change but also disrupt ecosystems, leading to biodiversity loss and detrimental effects on human health and economies. Effective policy interventions are needed to manage wildfires, mitigate their causes, and reduce their impact on communities and ecosystems.

Nature-Based Solutions: An Introduction

|

|

Nature-based solutions (NbS) are an umbrella term that involves using nature to address societal problems as well as create benefits for biodiversity and climate action. NbS have gained traction in international policy in recent years as a form of climate action being mentioned in various COPs. There is potential for NbS to combat the biodiversity and climate crises, however, the site-specific nature of NbS, makes it difficult to generalise and compare with other alternatives.

What Is Maladaptation?

|

Jun 2, 2024

|

Maladaptation is failed adaptation that increases vulnerability instead of reducing it. Seawalls and urban greening are examples of adaptive measures that have a risk of being maladaptive. Maladaptation can be prevented by focusing on holistic and inclusive long-term solutions

Tipping Points Part 2: Positive Tipping Points

|

Apr 16, 2024

|

Technological, social or cultural changes can reach tipping points, from which point they accelerate rapidly These tipping points hold the key to rapid progress on climate change We need to identify and accelerate potential tipping points to achieve positive change

Tipping Points Part 1: Negative Tipping Points

|

Apr 16, 2024

|

Climate change can cause damaging feedback loops, known as tipping points Tipping points risk dramatically worsening the impacts of climate change Even small temperature increases can determine whether these irreversible tipping points are hit

Climate Change And Extreme Events: Droughts

|

Aug 20, 2023

|

There are multiple categories of drought; agricultural, meteorological, hydrological and socioeconomic. Climate change has exacerbated the frequency and intensity of drought. In Somalia droughts have caused an estimated 43?,000 more deaths compared with the mortality levels in 2015–2016.

Climate Change And Extreme Weather Events: Introduction

|

May 1, 2023

|

There are no natural disasters, only natural hazards whose probability is being altered by the climate crisis. Extreme weather events together with the vulnerability and exposure of a population determine the impact of a disaster. Attribution studies provide a statement about how human greenhouse gas emissions have altered the intensity and frequency of an extreme event.

Global Warming: Analysing Its Current Stage ?

|

May 21, 2022

|

‘Global warming’ is defined by the International Panel for Climate Change (IPCC) as an increase in combined air and sea surface temperatures averaged over the globe over 30 years. Earth’s temperature is believed to have risen by 0.08° C per decade since 1880. Global warming reached about 1°C by 2020.
